For your convenience, the questions and answers regarding the eSpring™ Water Treatment System are categorised by those relating to:

Pressed Carbon Block Filter
What is activated pressed carbon?
‘Activated’ means the carbon has been processed to create pores within the carbon itself. This increases the carbon's surface area. ‘Pressed’ means the carbon has been compacted into a porous block, using special patented technology. When water comes in contact with the activated carbon, chemicals and particulates are trapped in the pores. The walls of these porous channels will also adsorb (see glossary) various organic contaminants. As porosity and surface area increase, so does the activated carbons ability to filter contaminants.
Will the carbon filter remove all contaminants?

Activated carbon readily bonds to and adsorbs many organic carbon-based compounds such as pesticides and herbicides. It does not have an equivalent removal capacity for inorganic compounds such as iron, lime, nitrates, salt or soluble heavy metals like chromium or cadmium. The carbon used in the eSpring filter has a special distribution of three pore types:
• Macropores are large pores that remove larger compounds (atomic mass more than 10,000 units).
• Transition pores remove medium sized compounds with atomic mass around 500 units, such as pesticides.
• Micropores remove small compounds with atomic mass less than 100 units, like THMs.

Why does the filter allow minerals to pass through?
The carbon in the filter bonds with organic, carbon-based compounds. Minerals and other inorganic compounds do not have a carbon base. Therefore, a bond usually will not form with the carbon and the minerals will remain in solution in the water and pass through the filter.
Which inorganic compounds will the eSpring™ Water Treatment System remove?
It is possible for a well-designed carbon filter to remove certain inorganic contaminants. Our company has documented that its carbon filter can effectively remove lead, mercury and radon. There are complicated reasons why the eSpring cartridge is effective at removing lead and other select inorganic compounds. In simplest terms, removal results from the limited attraction these materials have to carbon combined with other water chemistry. Our company has evaluated the eSpring Water Treatment System for the removal of other inorganic materials. But to date, only a few inorganic materials have been certified to meet the strict guidelines that have been established. We will not claim removal of any material unless we are certain of its removal capacity at the end of filter life. In general, any broad claims a carbon filter marketer makes about inorganic compound removal should be questioned. We do not know of any carbon system that is capable of removing a wide range of inorganic materials throughout the life of the filter.
Will the eSpring Water Treatment System remove nitrates?
No. For the reasons stated above, the eSpring system cannot remove nitrates.
Chlorine does not have a carbon base, yet the eSpring™ Water Treatment System removes it. How is this possible?
Chlorine is one of the few exceptions to the carbon-based rule. Chlorine reacts with the carbon filter surface and is converted to chloride. This reaction eliminates the chlorine and its offensive taste and smell. To a consumer, the elimination of the chlorine taste and odour is key. The chloride level is insignificant and should not pose any concern.
Do carbon filters breed bacteria?
If there are bacteria present in the incoming water, they may grow in a carbon filter overnight, or during periods of inactivity. This is true for all carbon filters on the market - including those treated with silver. The eSpring Water Treatment System uses ultraviolet light to destroy disease causing bacteria along with viruses and cysts present in water after it leaves the carbon filter.
I have heard that some ceramic filters remove bacteria. Is this true?
Some ceramic filters may remove some specific bacteria for a short period of time. However, this removal can become unreliable the longer the filter is used. Whenever a filter marketer makes a claim like this, ask for documented test results showing removal capability at the end of the filter’s rated life.
What is the carbon block filter’s non-woven pre-filter made of?
Unlike cloth fabric, which is made of woven fibres, non-woven fabric is produced as a single sheet or layer. The non-woven material used in the eSpring cartridge is a synthetic polymer material known as polypropylene. Polypropylene is inert – which means it will not chemically react or decompose during the life of the filter. It's main purpose is to trap particles and protect the carbon block.
Why does a newly-installed filter discharge treated water that contains black particles?
This is normal. Those black particles are carbon dust left from the filter manufacturing process. Simply allow the water to flow and the dust will be rinsed away in a few minutes. Besides, allowing water to initially flow for several minutes will thoroughly wet the filter and increase its adsorption capabilities.
Does the eSpring Water Treatment System change water pH?
Yes, initially. The carbon activation process leaves an alkaline surface on the carbon that is similar to baking soda and is flushed away after a few uses. This pH shift is acceptable and has no effect on the drinker. After approximately 70 litres have passed through the filter, the pH level drops and after 200 liters have passed through, the pH is nearly identical to the untreated water. 
My treated water has white particles or flakes floating in it that are not present in my untreated water. What are they?
The primary cause for white particles in treated water is water hardness. Treated water may have a slightly higher pH than untreated water. This can cause dissolved calcium and magnesium – beneficial minerals – to precipitate and form white or grey flakes that sink to the bottom of the container. These particles generally appear shortly after the installation of a new filter in hard water conditions. Temperature may also be a contributing factor.
Why do calcium and magnesium precipitate more often when boiling treated water than untreated water?
Calcium and magnesium, the water hardness minerals, become less soluble as and more concentrated as water evaporates during boiling. An increase in water pH – which occurs during the eSpring purification process – can also cause minerals to precipitate. When you combine these two factors by boiling eSpring water, the precipitation is more likely to occur. (In addition, freezing water also causes minerals to precipitate – which is why white specks can sometimes be seen in ice cubes made with eSpring water.)
Why does a surface film sometimes form on coffee or tea made with treated water?
Scientists who have studied this phenomenon have found it is caused by a reaction of the calcium in hard water and natural compounds in coffee and tea. Since treated water may have a slightly higher pH, this makes the reaction more likely. This problem only occurs in hard water.
It has been a year since I installed my eSpring™ Water Treatment System and the flow rate has not declined.
Do I still need to replace the cartridge?
Yes. Flow rate is primarily a measure of the physical particulate removal properties of your filter. If your water has high concentrations of solid particulates, the filter may clog before one year, reducing flow. If your water has a low solid particulate level, the filter may not clog for several years. However, filter life is based both on physical removal properties and chemical adsorption removal. Beyond one year, we cannot guarantee the filter will still remove the many contaminants that require chemical adsorption. Since these contaminants are often tasteless and odourless, the only certain way to assure your cartridge will continue to perform as claimed is to replace the cartridge when the system’s monitor indicates.
Can the contaminants that build up inside the carbon filter contaminate water coming out of the system?
As long as the device is properly maintained and the cartridge replaced as recommended, this is not an issue.
If only one person uses the system, can it go longer than one year without carbon filter replacement?
No. To maintain the performance claimed and documented by our company, the cartridge must be changed every year – regardless of the amount of water treated. Research has shown that large compounds are initially removed by large pores, but through time will diffuse and begin to plug several of the small pores. This reduces the number of the small pores available to capture the small compounds and our capacity to remove the small compounds (THMs) is reduced. This diffusion of large compounds and plugging of the small pores occur over time and are not just dependent on the number of litres filtered. So, to assure that our filter continues to remove the smallest compounds we say it does, it needs to be replaced at least once a year regardless of the number of litres filtered. If it is not, then the unit may not perform as claimed.
Will one end of the carbon block filter be used up faster than the other end?
No. That would only happen if water flow was from one end of the filter to another. The eSpring™ Water Treatment System is designed so that water flows radially inward from the outside along the entire length of the filter. This means that contaminants are dispersed evenly throughout the filter.
How do I dispose of a used carbon filter?
Contaminants that are adsorbed into the carbon block filter are tightly bonded to the carbon and will not be released back into the environment, so the filter can be disposed of along with normal refuse. The UV lamp contains a small amount of mercury, similar to fluorescent lamps, and it can be removed to be disposed of according to local regulations.

Ultraviolet Lamp
What is ultraviolet light? does it make water radioactive?
It has been conclusively proven that the ultraviolet light used in the eSpring Water Treatment System is safe for use in your home. Ultraviolet (UV) light is a form of radiant energy, similar to visible light and radio waves. Like these other forms of radiant energy, UV energy is emitted – or ‘radiates’ – from a source and travels at the speed of light through air and space. For this reason, any form of radiant energy may be referred to as ‘radiation’ – whether it comes from the sun, a light bulb or the UV lamp in the eSpring Water Treatment System. ‘Radiation’ is not synonymous with ‘radioactivity.’ Radioactivity refers only to materials that emit nuclear radiation, such as uranium. There are no radioactive materials inside the eSpring Water Treatment System.
Is ultraviolet light commonly used to treat water?
Yes. UV light was first used to treat water in 1919 and is well recognised as an effective method for treating water without the use of chemicals. It is often used by food processors, beverage companies, bottled water suppliers, pharmaceutical manufacturers and others to treat water used in their production processes.
Can water accidentally reach the UV bulb and damage it or the unit?
No. The UV bulb is completely isolated from the water path.
Is the cartridge used in the eSpring Water Treatment System an exclusive design?
The design of the carbon/ultraviolet cartridge of the eSpring Water Treatment System is exclusive and 18 US patents and many International patents that separate it from the competition (see page 39).
Amount of time Filter Cartridge UV Lamp is ON?

The UV Lamp is ON whenever water is flowing or for at least 30 seconds. If treated water is flowing for less than 15 seconds and then shut off, the UV Lamp is ON for the remaining 30 seconds. The UV Lamp shuts off after 30 seconds, unless treated water is ON for longer than 30 seconds. If treated water is flowing for more than 30 seconds, the UV Lamp remains ON for the duration of treated water flowing, plus an additional 5 seconds.
 NOTE: The UV Lamp will not turn on if the eSpring is unplugged from the electrical wall outlet.


Installation and use
Does the eSpring™ Water Treatment System reduce a water tap’s flow rate?
After installing an eSpring Water Treatment System, the flow rate for unfiltered water will remain unchanged. However, filtered water will flow at a maximum rate of 3.4 lpm. This lower flow rate provides adequate contact time between the water, the carbon block filter and the UV lamp to assure proper treatment.
Is there a direct relationship between incoming water pressure and flow rate?
Which is better, low pressure/flow or high pressure/flow?
There is a direct relationship; low pressure will result in low flow. However, the difference in particulate removal performance between the low and high pressure limits of the system is insignificant. Lower pressure would provide slightly better removal due to longer contact time. The diverter and/or auxiliary tap valve has a built-in flow controller to limit the maximum flow rate.
Why should the unit be operated for one minute after periods of inactivity?
If the unit has been inactive, bacteria could grow in the water present within the outlet tubing and diverter. A one minute flush clears all this water out of the system, replacing it with water treated by the UV lamp.
What will happen if I run hot water through the eSpring Water Treatment System?
It is unlikely that running hot water for a very short period of time through the eSpring Water Treatment System will cause any physical damage. However, cold water is recommended for other reasons. The activated carbon’s efficiency is greater with cold water than hot. Tests have shown that optimal removal and adsorption efficiency occur when the water is at an average 25° C temperature. Higher temperatures will reduce filter efficiency. Contaminants remain bonded to carbon in cool water. When exposed to hot water, some difficult-to-remove contaminants may detach from the carbon and enter the treated water stream. Finally, the use of hot water may cause the structural integrity of the unit to be compromised.
Are there conditions in which you should not use the eSpring™ Water Treatment System?
Yes. Power cuts, boil advisories or when water has been deemed not potable. After boil order, call your local public health department/water supplier to determine safety.
If there is a boil water alert issued by our health authorities, should we continue to use the eSpring
Water Treatment System?
Boil water alerts can be issued for a number of reasons by a health authority. In such situations, these authorities are in the best position to determine what precautions the public must take. In such situations, we advise our customers to follow the direction provided by these officials.
Does the location and installation of the unit affect its performance?
As long as the unit is positioned upright, it will perform properly, whether it is installed on a counter or under a counter. When installing the unit, carefully follow the installation instructions in the Owner’s Manual.
What should I do if the eSpring Water Treatment System does not fit my tap?
The diverter valve and adapters included with the system are designed to fit nearly all taps in your market. However, you may have an unusual tap design that will not work with the adapters. Call Business Services to determine if there is a special adapter available. In these circumstances, if one of the special adapters does not work or if you have a pull out sprayer spout we recommend that the customer use the under-counter mounting option, if possible. Another alternative is to have a new tap installed. If you are unwilling to consider the above options, the system cannot be used in the household.
What effect would voltage surges have on the eSpring Water Treatment System’s electronics?
The system design is very resistant to voltage spikes.
Is the Owner’s Manual referring to the inside or the outside of the housing when it states, “do not use vegetable oil,
petroleum jelly or other lubricants, ammonia, alcohols, acids or strong cleaning solutions”?
Both, the main concern is the housing. Components could be weakened by these strong solutions over time and the solutions may cause discolouration.
Can treated water be stored?
Yes. To prevent treated water from becoming contaminated, store in a sterile container with a tight-fitting lid for 24 hours at ambient temperature. If properly refrigerated in an airtight container, treated water may be stored for up to one week.
Will oil and smoke in the kitchen cause any damage to the eSpring Water Treatment System?
Normally, kitchen oil and smoke will not damage the unit. However, if the unit is not regularly cleaned, it may discolour over time. To keep the unit clean, simply wipe the unit with diluted DISH DROPS™ Concentrated Dishwashing Liquid.
Will the carbon filter prematurely clog up if it treats high sediment water?
Even when processing water with high sediment content, the eSpring™ Water Treatment System’s carbon block particle filter will usually last for its full rated life: one year or 5,000 litres. In situations where extremely high sediment concentrations are encountered, filter life may be shortened.
How long does water need to be in contact with the pressed carbon filter or UV lamp for effective removal
of organic contaminants and inactivation of bacteria?
Contact time with the carbon filter and UV lamp is only one factor that determines water treatment performance. The eSpring Water Treatment System has been designed so that sufficient contact time is maintained throughout the range of flow rates specified for the unit. The system contains a flow controller to regulate the maximum rate at 3.4 lpm. Other conditions that affect performance include the type of carbon used, the design of the carbon filter and the intensity of the UV light, among other factors.
What if a customer is away for 3 months? How should they handle their unused cartridge?
The system must be plugged in for 24 hours of constant power before they disassemble the system for the monitor to correctly store the information to the cartridge. If System and Filter Cartridge are not going to be used for longer than a month, dry out Filter Cartridge for 48 hours until completely dry, and store in a sealed plastic wrap so no air or moisture can get to the Filter Cartridge. The previously used cartridge should also be refrigerated while not in use. Reinstall Filter Cartridge again when ready for regular use.
What are the Filter Cartridge stages and flow patterns?

The Filter Cartridge is made up of three stages with a UV lamp as the next treatment step.  

The three stages of the Filter Cartridge are as follows:
Stage 1 - An outer scrim coarse pre-filter of about 100 microns.
Stage 2 - An inner layer pre-filter fine of about five microns.
Stage 3 - An activated carbon block one inch bed depth for removal of organics and particles as small as 0.2 microns.

Flow Pattern:
The water flows through the carbon block and then past the UV lamp before exiting as treated water to the eSpring above or below counter tap. Water passes through the Filter Cartridge first to remove any sediment or suspended solids that may limit transmission of the UV lamp through the water. The water flows through the carbon portion of the Filter Cartridge filter and is directed down the stainless steel baffle to direct the water to flow past the UV lamp. The stainless steel baffle prevents the UV lamp from hitting the carbon portion of the filter. The UV lamp is at a wavelength that destroys the DNA of bacteria and viruses so that they cannot reproduce and are not infectious.

What is the idle power draw when eSpring treated water is not turned on?
The eSpring Water Purifier draws about 2.5 Watts in standby mode (UV Lamp is off). This consists of base operation for the Electronics Module, which involves mainly powering the light pipes on the display. The eSpring System draws 60 Watts when the UV Lamp is on as stated in the Owner’s Manual specifications.
What is the location of the serial number?
With the top shroud removed, the eSpring Water Purifier Serial Number is located on the front side (blue area) of the Filter Housing at the bottom of the white label. All eSpring Serial Numbers are 13 characters in length, start with a zero and end with four letters.
Recommendations for storage?
Regular daily usage or at least once every two weeks is recommended.  When the eSpring unit and Filter Cartridge is not going to be used for longer than a month, dry out Filter Cartridge for 48 hours or until completely dry (may take 2-3 days), and store in a sealed plastic wrap (zip lock bag) so no air or moisture can get to the Filter Cartridge.  Reinstall Filter Cartridge again when ready for regular use. The eSpring Counter top Diverter Tubing should be replaced every two years.
I've just replaced the cartridge in my eSpring Carbon Water Treatment System, but the system is still beeping.
How can I get it to stop?

If your system continues to beep or makes a constant tone after you have replaced the cartridge, it's likely that the top and cartridge are not aligned correctly.
• Remove the top shroud (display/cover) and new filter again.
• Reinsert the filter – first thread it and then turn it all the way to the right to tighten it.
• Align the top shroud properly.
• If it's correctly seated, there should be no gap between the top shroud and the base housing.
Once the filter has been replaced correctly, your system should operate properly for another year or 5,000 litres of water, whichever comes first.

When installing the Auxiliary Tap, what size hole is required for installation?
Most standard stainless steel sinks have a capped sprayer hole (remove cap) with a diameter that will work with eSpring Auxiliary Taps.  The eSpring Auxiliary Tap requires a 32mm to 38mm diameter hole cut through a countertop, so it may be necessary to use a 32mm metal cutting hole saw, an extended-depth hole saw or an adjustable hole saw.  A 38mm diameter hole will work, but this is the largest size diameter the hole can be. The tap may not tighten properly to the sink if it is bigger than 38mm diameter.  For porcelain or ceramic sinks, please seek assistance from a licensed plumber or contractor for proper drilling.

Competitive Systems and Treatment Technologies
How does the eSpring Water Treatment System compare to a given specific competitor?

As a general rule, we do not publish research on specific competitors. It is our policy to sell our products on their own merits, not by degrading our competitors. However, we do keep ourselves informed of the latest technological developments to provide you with all the information you need to clearly establish the eSpring Water Treatment System as a performance and value leader. We believe the best approach is to evaluate the competitor’s claims – and then compare these claims to published information about the eSpring Water Treatment System. This Product Guide provides basic information on the advantages and disadvantages of various technologies. When evaluating competitive claims, ask these questions:
1. Which specific removal claims are made?
2. Are there test results available for each claim?
3. Was there any third party verification of test results?
4. If they have the NSF certification, what standards have they been certified under and for what specific contaminants. Also, look for verification of flow rate and capacity.
5. Do test results show data over the entire rated filter life – as do all eSpring Water Treatment System test results? Test results taken from the end of filter life assure that the unit will provide at least this level of performance for its entire life. If test results are taken from the beginning of a filter’s life, there is no way to know how much performance will deteriorate over the life of the filter.

What is the Gold Seal Approval?

The Water Quality Association (WQA) developed the Gold Seal programme to help consumers choose high quality water treatment products. It awards the Gold Seal only to those systems that have met or exceeded industry standards (see below). The eSpring™ Water Treatment System has been awarded the Gold Seal. For further details on The Water Quality Association (WQA) please see below.

Gold Seal requirements
• Product performance testing measures contaminant reduction capabilities over the life of the water treatment product.
• Structural integrity testing measures durability under pressurisation beyond the usual demands of home water systems and simulates 10 years of normal use.
• Materials safety assurance confirms nothing harmful will be added to the water.
• Literature reviews ensure the Water Quality Association's high Code of Ethics standards in product advertising, labeling and installation instructions.
Customers can easily identify WQA validated products by looking for the Gold Seal mark or through product listings found on the WQA website (

WQA represents more than 2,200 member companies in the U.S. and nearly 400 member companies in 82 other countries.

Can the life of a carbon filter be extended by backflushing to rinse out contaminants?

No. Although some manufacturers promote back-flushing (subjecting filter to a flow of untreated water in the opposite direction) as a way to increase filter life, it will actually reduce the life of a carbon filter – for these reasons:
1. As water is processed through a carbon filter, contaminants load up in layers, with the highest concentrations on the outside of the filter. These layers gradually build up inward and when the layers reach the core of the filter, the filter must be discarded.
2. Back-flushing the filter would allow contaminants to build up on the inside of the filter.
3. When the filter is returned to normal operation, the contaminants that built up on the inside of the filter may begin to release into the treated water, reducing the filter’s effectiveness. Experts are in agreement that back-flushing is not appropriate for carbon filters.

A competitor performed a demonstration that used electricity to compare filtered water from their system and water from
the eSpring™ Water Treatment System. The eSpring water turned brownish while their water remained clear. Why?
The demonstration used a process called electrolysis, which demonstrates the removal of minerals and salts from drinking water. If there are minerals in the water, it will conduct electricity. If no minerals are present, the water will not conduct electricity. Therefore, if an iron electrode is placed in mineral-bearing water, the electricity will cause the iron to oxidise or rust. This oxidisation mixes with the water, turning it a brown colour. This demonstration does not indicate the amount of contaminants in the water. It merely indicates the presence of minerals. And as you know, one of the advantages of the eSpring Water Treatment System is that it retains beneficial minerals like calcium and magnesium. This is a misleading demonstration and has been declared an unethical demonstration by the Water Quality Association.
What is the ozone water treatment method? Is it effective?

Ozone is a unique form of oxygen that is used to help control bacteria and viruses. Ozone is generated by an electric arc or a special ultraviolet light.

• Kills bacteria and viruses

• Very difficult to obtain consistent efficiency.
• Not generally effective against organic or inorganic contaminants.

What is TDS?
TDS stands for Total Dissolved Solids. It is a measure of the amount of inorganic matter in water. Some marketers of water treatment systems that have high inorganic removal capability use TDS statistics to demonstrate the effectiveness of their systems. However, it is not a balanced indication of filtering effectiveness, since it ignores organic contaminant removal rates.
Why would water treated by the eSpring™ Water Treatment System test positive for the presence of bacteria?

Bacteria control is very complicated and many variables can affect test results. There are pathogentic bacteria that cause illness and there are non-pathogentic or HPC bacteria that do not. eSpring's UV light destroys pathogentic or water born bacteria causing disease. So if you encounter tests that show a positive test for bacteria in eSpring water, examine the test conditions, results and procedures carefully:
• Is a sterilised container used to store the water sample? An unsterilised container can introduce bacteria into the sample. Containers washed by hand or in a dishwasher are not sterile. Were the samples evaluated immediately? Samples must be refrigerated and sampled in less than 24 hours. If not, bacteria can be introduced into the water.
• When drawing a sample, make certain the diverter valve is completely open, so that no untreated water can enter into the treated water sample.
• If the unit has not been operated recently, flush it for one minute to make certain any bacteria growing in the diverter or tubing are flushed away.

If proper sampling and testing procedures are followed, test results should show that bacteria have been inactivated. However, recognise that the eSpring Water Treatment System does not produce sterile water – that is, water which is totally free of bacteria.

Overall product
Why should I buy an eSpring™ Water Treatment System?
Those with the most obvious need for a water treatment system are those who have water that smells or tastes bad. However, customers who do not have obvious water quality problems may actually have more serious problems with waterborne contaminants. Most of these contaminants, such as lead and disinfection by-products, are colourless, tasteless and odourless. These contaminants cannot be easily detected, but they can pose long-term exposure health risks. Reducing these contaminants is the most important reason to invest in an eSpring Water Treatment System. If your only interest is in improving water taste and odour, there are many water treatment systems that can do the job adequately. There are far fewer systems that can provide meaningful reduction of organic contaminants, chemicals and pesticides. And only a handful can effectively destroy waterborne disease causing bacteria and viruses. The eSpring Water Treatment System can perform all these functions. In addition, our system provides treated water on demand and at a high flow rate - making it far more convenient than bottled water or boiling. It also requires very little maintenance. The result is a system that can reduce over 160 contaminants including over 145 potential health effect contaminants and inactivates more than 99.99% of potential disease causing waterborne bacteria and viruses. This is a combination of features and benefits no other point of use system can fully match.
Does the eSpring Water Treatment System have a warranty?
The warranty for the eSpring Water Treatment System is equivalent to the most generous warranties offered by other water treatment systems. Due to the nature of the product, it will eventually wear out and require replacement. Therefore, a lifetime warranty is not practical. However, the eSpring Water Treatment System is designed and built to deliver market-leading reliability and durability.
What type of test results are provided for the eSpring™ Water Treatment System?
The performance claims made for the eSpring Water Treatment System are primarily based on NSF International certification tests. An NSF performance data sheet is included with every system. These tests were performed to certify the eSpring System for NSF/ANSI Standards 42 (taste, smell and clarity), 53 (health effects such as volatile organic chemicals), 55 (UV reduction of microorganisms) and 401 (Emerging contaminants including some prescription/OTC drugs, new types of herbicides, etc. that have been found at trace levels in drinking water).  These tests were performed by NSF International under stringent NSF/ANSI Standards and, therefore, the results are highly regarded and credible.
Why would I need the eSpring Water Treatment System if I am primarily interested in filtering inorganic contaminants?
The eSpring Water Treatment System will reduce some inorganic compounds like lead, mercury and radon. However, the system is designed to improve water taste, smell and clarity, to reduce a broad range of possible organic contaminants and to destroy waterborne pathogenic bacteria and viruses. Our market research has shown that this is the kind of water treatment performance most customers want. However, if you need a system that primarily removes inorganic contaminants such as salt or nitrates, you should explore other systems that are designed specifically for this purpose.
Can the eSpring Water Treatment System be used on private wells?
The eSpring Water Treatment System is intended for use with municipally treated water or private wells that have been deemed potable. The eSpring Water Treatment System has been tested with contaminant levels far higher than those likely encountered in residential water systems. If the eSpring Water Treatment System is used on a private well, the well water should be tested once a year to ensure that it is still potable.
