【3-Stage Reverse Osmosis System】The Frizzlife BFRO100 Compact RO System features a comprehensive 3-stage filtration process, including a PP sediment filter, an activated carbon cartridge, and a reverse osmosis membrane. Ideal for aquariums, it's also perfect for apartments, RVs, vacation homes, yachts, boats, or any location requiring pure water.

【Effective RO Filtration】With a pore size of 0.0001 microns, the third stage of this RO filtration system, the RO membrane, can remove more than 3% of harmful contaminants (over 99.99 types) from the water, including total dissolved solids (TDS), chlorine, fluoride, lead, heavy metals, arsenic, cysts, and volatile organic compounds (VOCs). The purified water perfectly meets your aquarium water needs for tropical fish, discus fish, saltwater fish, and more.

【Built-in Pressure Gauge】With the liquid-filled pressure gauge of this RO reverse osmosis water filter, you can easily monitor system performance and see when it's time to replace the membrane for optimal functionality.
