ZRO-4 Undercounter 4 Stage Zero Waste RO Water Filter
Item #: wfuz4

Forget about expensive delivery services and bottled water. Invest in an affordable, long-term option that uses your existing water supply and requires little maintenance while keeping your counters clear and your fridge clutter-free. Allergy Be Gone’s ZRO-4 undercounter system uses the same state-of-the-art technology found in water purification and bottling factories right in your home’s kitchen. Many similar models create as many as four gallons of waste per gallon of purified water, while this zero-waste reverse osmosis system does just the opposite. Environmentally-friendly and budget-conscious families alike will appreciate this model’s cost- and water-saving features.

Each ZRO-4 filter is designed to pass water through four different stages of filtration. The first stage uses a 5-micron sediment filter to remove dirt, sand, and dust. The second 10-micron carbon block filter reduces the taste and odor of chlorine. Next, water passes through a thin film composite (TFC) membrane to separate up to 25 gallons daily of purified water from the impurities down to 1/10,000 of a micron and up to 98 percent of total dissolved solids (TDS). The final filter is a granular-activated carbon (GAC) filter to enhance taste. These four stages come together to reduce arsenic, barium, selenium, copper, and other contaminates to treat allergies while improving the overall taste of your water supply.

The ZRO-4 is IAPMO and NSF-tested and certified to Standard 58, ideal for areas with low water pressure or higher water costs. You will conserve water with every use with our zero waste design. No drain connection is needed for quick installation. This complete system takes no prior plumbing knowledge to maintain. Change the first two filters after either six months of use or 1350 gallons of water. The third stage only needs to be replaced after two to five years, while the fourth filter should be replaced annually. All of the replacement accessories you need are available at Allergy Be Gone for convenient one-stop shopping.
