Q & A

Getting the latest innovations in water filtration technology in your home doesn’t have to mean paying to completely remodel the kitchen. The Anchor AF-5001 - 4-Stage Reverse Osmosis Water Filter combines the latest technologies in water filtration for residential use, membrane separation (reverse osmosis), activated carbon adsorption, and conventional filtration, to reduce a wide spectrum of contaminants that can be found in water. This system comes with a 2.2 gallons capacity storage tank. 

Superior quality, made from NSF/FDA-approved components so you can be certain you’re getting a truly reliable water purification system to improve the clarity, purity, safety, taste and smell of your water for drinking and cooking.

Includes 100% lead-free sleek designer chrome finish faucet to match your modern kitchen. The non-air gap faucet has one water line that goes up to the faucet and there is no gurgling sound. Advanced ceramic disc valve structure provides smooth operation and precise flow control.

Reverse Osmosis Filtration Stages:

• Stage 1 - 5 micron NSF polypropylene sediment pre-filter - extracts suspended materials such as sediment, rust, insects, and other particles down to 5 micron.

• Stage 2 - 5 Micron NSF Activated Carbon Block - High purity coconut shell activated carbon block filter reduces sediments, taste, odor, color, SOCs(soluble organic compounds) like pesticides, dioxins, and VOCs (volatile organic compounds) like chloroform and petrochemicals.

• Stage 3 - NSF-Certified TFC (thin-film composite) Reverse Osmosis 50 GPD membrane - this high-rejection filter removes upto 99% of contaminants and wide range of total dissolved solids (TDS) like arsenic, fluoride, hexavalent chromium, nitrates, lead, copper, barium, mercury, cadmium, selenium, many other heavy metals, and bacteria.

• Stage 4 - Inline GAC filter - NSF Media - Polishes water by removing any dissolved gases, bad taste and odor before water finally ends up in your glass or pot.

Each RO system comes complete, ready to install, and with the following installation kit: Purification unit, Tank, Faucet, Wrench, and Manual.

Age of the filters depends on GPD consumed and quality of feed water.

  • i just bought this thing and the drain keeps draing none stop what do i do to stop it

    If you are consuming water, the system will refill it by filtering more water. This process is automatic & continuous, and that is how Reverse Osmosis systems work. Do note that in RO systems, for every 1 gallon of water, about 3-4 gallons is rejected by the system as it contains high amount of dissolved solids. This is normal in any RO system and hence the draining.

  • What it the ratio of filtered potable water to discharged water: i.e gal/gal

    The ratio of filtered to discharged water is about 1:3.

    It's like using water to clean water, similar to using water to clean any other thing like utensils, fruits & vegetables, clothes etc.
