[Premium Sediment Filter] The first stage of the Frizzlife Compact reverse osmosis system is the sediment filter, made of high-precision (10 micron) PP material, which perfectly removes most large particles such as sand, dirt, sediment, rust, and more from the water. It is recommended to replace it every 6 months.

[Activated Carbon Block] The second stage of the RO water filter for aquariums and water treatment consists of a high-quality and 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 final stage of the RO system—the reverse osmosis membrane—can remove more than 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 perfectly meets the water needs of an aquarium with tropical fish, discus fish, saltwater fish, and more. Replacement is recommended every 12 months.
