【4-stage reverse osmosis system】The Frizzlife FAF100 Compact RO System features a comprehensive 4-stage filtration process with a PP sediment filter, activated carbon cartridge, reverse osmosis membrane, and DI resin filter. Ideal for aquariums, it's also perfect for apartments, RVs, vacation homes, yachts, boats, and any location that requires clean water. It's also an excellent solution for rental properties or locations where installation isn't possible.

【Activated carbon block】The second stage of the RO water filter for aquariums and water treatment consists of a high-quality, high-precision 5-micron activated carbon block. It effectively blocks sediment and reduces 99% of chlorine, cysts, volatile organic compounds, and bad tastes and odors in the water. Replacement after 6 months is recommended. The first and second pre-filters significantly extend the lifespan of the delicate third-stage reverse osmosis membrane.

【Effective reverse osmosis filtration】With a pore size of 0.0001 microns, the reverse osmosis membrane, the final stage of the RO system, can remove over 99.99% of harmful contaminants (over 1,000 types), including arsenic, lead, cysts, copper, and fluoride, from the water and reduce total dissolved solids (TDS) by over 99%. The purified water optimally meets the water needs of an aquarium with tropical fish, discus fish, saltwater fish, and more. Replacement after 12 months is recommended.

【Easy installation and replacement】The compact RO water filter kit is pre-assembled. Follow the step-by-step instructions and easily install it yourself within 10 minutes. The system package includes the RO water filter, a quick-connect faucet connector, a faucet diverter, an RO membrane housing wrench, a locking clip wrench, and mounting screws. This allows you to supply the system with RO water at any time. You can also mount it on the wall with the included screws.

【100 GPD and convenient use】 With a capacity of 100 GPD, the three-stage reverse osmosis aquarium water filtration system can produce 4 gallons of filtered RO water, providing daily water for your fish, plants, and pets. Connect and open the faucet whenever you need RO water. Compatible with M100, F22, and 24/3-inch male thread faucets. The RO system package also includes a T-diverter, allowing you to use your faucet and RO system simultaneously.
