Superior Water Purification: Effectively removes up to 99% of impurities found in tap water such as chlorine, arsenic, fluoride, lead, and much more to ensure that your family is drinking the cleanest and healthiest water possible.


High Capacity: With a capacity of 400 gallons per day and a flow rate of up to 0.4 gallons per minute, this system provides a constant supply of purified, high-quality waterfor your home.


3-in-1 Filtration: The first stage filter uses a combination of a sediment filter and carbon block to remove dirt, sand, dust, rust, and chemicals like chlorine, pesticides, radon, benzene, VOCs, and more. Then the 2nd stage filter, which is the reverse osmosis membrane removes even smaller particles down to 0.0001 microns plus 1000 morecontaminants like heavy metals (arsenic, lead, iron, mercury, and more), harmful
chemicals (fluoride, chlorine, chloramine, PFAS(forever chemicals) and more) and reduces TDS (total dissolved solids) levels. Lastly, the third stage filter, a granular activated carbon cartridge, eliminates any lingering gasses, foul tastes, and odors to enhance the taste of the purified water.


Filter Lifespan: Replace filters every 6-12 months. The RO membrane (Stage 2) can last longer if you have a water softener. This can vary depending on the quality of the feed water.


Compatibility: Only compatible with APEX EXPRT MR-5400 tankless RO system.
