Here is a useful list of the most frequently asked question about the eSpring Water Puri fier.
Are both the carbon block and UV light really necessary?
While carbon filtration – used with varying degrees of effectiveness in many water treatment options, like pitchers and faucet-mount filters – is the most effective single treatment method available to most homeowners, we do not think it is enough. That is why we have developed the dual-technology eSpring™ cartridge/filter/UV light. Its carbon block filter removes compounds that affect taste and odor along with organic health-effect contaminants (such as pesticides and VOCs). Our carbon filter can also reduce inorganic contaminants (such as lead, mercury, and radon). The UV light destroys potential microorganisms providing a protective barrier for your family.
Can I still continue to use the unit without changing the cartridge when I am supposed to?
You really should not do that. cartridge life is based on the ability of the carbon block to trap contaminants; if you leave the carbon block unchanged when it has filled up with contaminants, it will not be able to trap new contaminants. Depending on how long it has been left in service, there’s a chance that accumulated contaminants may detach and “dump” into the treated water, making the treated water even worse than the water coming in. The UV lamp is rated for a certain number on UV “ON” time and starts. Depending on your use pattern it may depleted it’s life prior to the carbon filter. Guaranteed performance is the goal of the eSpring™ brand.
Will the carbon filter remove all contaminants?
No. Activated carbon readily adsorbs (causes to stick to its surface) organic carbon-based compounds, but it does not have an equivalent removal capacity for inorganic compounds such as iron, lime scale, nitrates, hardness minerals (such as calcium and magnesium), or soluble heavy metals like chromium or cadmium.
Can I use the eSpring™ Water System on well/bore water?
Yes. The eSpring Water System was designed for use on potable (drinkable) water sources such as municipal water or potable well/bore water. It is not intended for use on lake, river, or other untreated water. We recommend that you have your water tested regularly if you use well/bore water.
Can treated water be stored?
Yes. To prevent treated water from becoming contaminated, store in a clean container with a tight-fitting lid. If properly refrigerated in an airtight container, treated water may be stored for up to one week.
Can water damage the UV bulb?
No, the UV bulb is completely isolated from the water path.
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 virtually any filter in the market, including carbon filters, even those treated with silver. The eSpring™ Water System uses ultraviolet light to destroy any harmful bacteria present in water after it leaves the carbon filter.
Does the eSpring™ Water System change the taste of water?
The taste of water depends on what’s in the water. The eSpring Water System does not remove sulfur, but it will remove many substances that affect taste, odor, and clarity of water, such as particulates or chlorine.
Does the eSpring™ Water System remove fluoride?
The eSpring Water System does not remove fluoride from water because fluoride is not naturally attracted to carbon.
How does the activated carbon-block filter work?
Most health-related contaminants (pesticides and their by-products, VOCs, THMs) contain carbon molecules, and carbon molecules tend to bond together. So contaminants in tap water will tend to bond with the carbon block filter. We "activate" the carbon through a special heat process that creates thousands of pores. This increases the surface area available to attract contaminants. The carbon is then pressed together to create a fixed carbon block. This increased surface area increases the ability of our filter to attract and "trap" carbon-based contaminants as water passes through the block. Since the surface area of the pores is limited, the carbon filter has a limited trapping capacity. That’s why the cartridge/filter must be replaced every year.
How will I know when it is time to change the cartridge?
You will know just by looking at the LED display on the unit. Using a bar gauge indication, it shows you at a glance the cartridge's remaining life. When it is time to change, it makes an audible sound and the display flashes in red.
What is so special about the UV lamp?
Ultraviolet light is an effective way to destroy microorganisms without the use of chemicals. The UV lamp produces light in a specific wavelength that is destructive to the RNA and DNA of microorganisms. The light has to be the right intensity and the water must be exposed to the light for a specific amount of time to properly dose the water.
