Under Sink & Under Counter WATER FILTERS

Water Filters Home Page > Under Counter & Under Sink Water Filter Systems

Our Under Sink and Under Counter water filters utilize the latest technologies in the water industry coupled with over 40 years of manufacturing expertise to provide you with high capacity filtering, the most effective filtering, producing the healthiest and great-tasting water conveniently and at the most affordable prices. These home, apartment and office use water filtering systems are attractive, easy to install and use.

Our Under Counter Water Filters are BPA FREE!

Our under counter / under sink water filters remove many contaminants*^ from your water while providing exceptional filtering for a long time (from 10,000 to 30,000 gallons of filtration**) before cartridge filter replacement - the unique high capacity and multi-stage design means no more over-priced and less effective water filters with replacement cartridges that often must be replaced after only a couple hundred gallons of filtering!

*^when those contaminants are present

  • All our CQ water filtering systems are BPA FREE!

Undersink water filter installation and 6 stage filtering informationCQ Classic Disposable Undersink Water Filter*** system eliminates the impurities of tap water to offer great taste and pureness. The perfect solution for any household, it is quick and easy to install and use, attractive, convenient, and effectively removes many contaminants*^ from your water via the 6 stage filtering process. This solid state water filter uses the latest technologies that blend the adsorption capabilities of coconut shell activated carbon (GAC) with Eagle Redox Alloy and more.

The disposable system can be easily back washed. Semi annually back washing of the unit not only ensures balanced filtration and eliminates the potential for channeling, but also back-flushes the unit.
