The eSpring® Carbon Water Treatment System filter replaces the filter shipped with your original unit and is easily installed. The filter’s “smart-chip” monitors system performance and sends messages about function or replacement timing, which appear on the eSpring unit's lighted display. The patented carbon-block filter effectively reduces more than 140 potential health-effect impurities, while allowing beneficial minerals like calcium and magnesium to pass through.
If you registered your eSpring Carbon Water Treatment System when you purchased it, you will be contacted automatically with a reminder to replace your cartridge. You can also set up an automatic annual purchase through the DITTO® delivery service, at checkout.
Will the carbon filter reduce all impurities?
No. Activated carbon readily adsorbs (causes to stick to its surface) organic carbon-based compounds, but it doesn't have an equivalent reduction capacity for inorganic compounds such as iron, nitrates, hardness minerals (such as calcium and magnesium), or soluble heavy metals like chromium or cadmium.
Can I still continue to use the unit without changing the filter when I’m supposed to?
It is not recommended. The filter life is determined based on performance testing. Failure to maintain the unit as recommended may impair the performance.
What inorganic compounds will the eSpring filter reduce?
It's possible for a well-designed carbon filter to reduce certain inorganic impurities. The eSpring carbon-block filter has been certified for the reduction of lead, mercury, and radon and its decay products.
How does the activated carbon-block filter work?
Carbon molecules tend to attract other carbon molecules. Most health-effect impurities pesticides and their byproducts, VOCs, and THMs, for example contain carbon molecules. The eSpring carbon-block filter is "activated" carbon, processed to create pores in the carbon that increase its surface area. This increased surface area increases the ability of our filter to attract and "trap" carbon-based impurities 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 filter must be replaced every year.
Does the eSpring unit change the taste of water?
The taste of water depends on what's in the water. The eSpring Carbon Water Treatment System removes chlorine taste and odor and improves the clarity of water.
How will I know when it's time to change the filter?
You'll know just by looking at the LED display on the unit. It shows you at a glance the filter's remaining life on an indicator that resembles a gas gauge on a car. When the filter is nearing the end of its life, the last bar becomes yellow and the unit beeps once when activated. When it is time to change, the last bar becomes red and the unit beeps when the water is on.
How often should I change the batteries?
There is an indicator light on the display module that will tell you when your battery is dead. It is best to change them each time you change your filter even if there still appears to be life in the batteries. Changing the batteries does not reset your unit.
Is the filter hard to change?
No. The patented, easily replaceable eSpring replacement filter screws in like a light bulb and lasts for up to 1,320 gallons or one year, whichever comes first. And the eSpring monitor automatically resets itself when the filter is replaced. There is simply nothing else this easy out there.
I've just replaced the filter 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 filter, it's likely that the top filter is not installed correctly.
- Remove the top shroud (display/cover) and new filter again.
- Reinstall the filter – press into the bracket and then twist to thread it until it comes to a stop.
- 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 up to 1,320 gallons of water, whichever comes first.
