This dual-stage drinking water system delivers clear, clean, fresh-tasting water for drinking and cooking. Flow controlled filtration ensures a long "contact" time with the activated carbon cartridges for superior results, making this an ideal system for not only filtered drinking water, but also for icemakers, water coolers, or anywhere else you want to improve the taste and odor of your water. The included cartridges, according to the manufacturer, will typically filter up to 1,000 gallons of water before needing replacement, though please note the actual quantity will vary depending on your particular water conditions. This is about one year's usage for an average family of four but, if you can afford it, we recommend changing the cartridges more frequently at about every 6-9 months to get top, peak performance from the carbon (recommended for all brands of carbon).

Frequently Asked Questions

Q. "When should I change my filter?"
A. According to the manufacturer, these filters will work for about 1 year (1000 gallons). However, we recommend replacing that you replace your filters every 6 to 9 months for peak performance. Carbon filters absorb chemicals like a sponge, and once saturated the carbon can no longer absorb any more chemicals and must be disposed of. For other replacement filters, click here.

Q. "What is a micron rating?"
A. The average size of the openings between pieces of the filter media are represented in microns. For example, a 40-micron filter has larger openings than a 5-micron filter. Consequently, the 40-micron filter element will let larger particles pass through the filter than the 5-micron element. As a general rule, the smaller micron rating for a filter is better, but as with most everything, there is a trade-off. Flow capability usually drops off as the micron rating gets smaller.
