4-Stage MyAquaFilter Countertop RO System Includes:

1st Stage: Premium Quick-Connect 5-micron sediment filter traps dust and rust particles, extending the life of the system and membrane.
2nd Stage: USA-made Quick-Connect T28 coconut activated carbon filter removes VOCs, chlorine, chloramine, pesticides, herbicides, THMs, radon, solvents, and hundreds of other chemicals. It also eliminates odors, discoloration, and unpleasant taste.
3rd Stage: Premium high-rejection TFC-type Reverse Osmosis membrane (USA-made). Removes 96%–98% of total dissolved solids (TDS) and contaminants such as arsenic, fluoride, lead, chromium, radium, bacteria, viruses, nitrates, uranium, and more. Available in 75 GPD (produces 1 gallon in approximately 22 or 11 minutes, respectively).
4th Stage:  Premium T33 coconut shell activated carbon filter to remove any remaining taste.

System Highlights:

This Reverse Osmosis system produces approximately 3–6 gallons of pure water per hour. It’s ideal for homes with a relatively clean municipal water supply (TDS level between 20–300 ppm). It removes more than 220 hazardous contaminants.

What to Expect:

• If your tap water is around 300 ppm TDS, expect filtered water to measure 20–46 ppm after 4–6 days of regular use

• System dimensions: 14″ x 6″ x 6″

• Produces 1 gallon every 11–22 minutes (purification speed depends on GPD rating; water drips slowly, not flows)

• RO systems split water into pure and waste streams — typical ratio is 1 part pure to 2.4 parts waste

Why Choose Reverse Osmosis?

The heart of any RO system is its membrane. RO membranes filter at 0.0001 microns — roughly 1,000 times finer than typical water filters — ensuring exceptional purification quality.
