This is our best performing Countertop Reverse Osmosis System specially designed for hard water. The Reverse Osmosis System easily attaches to your kitchen faucet without the need for a plumber. Ideal portable solution for your apartment, home, RVs, aquarium or during your travel time.
This advanced 5-Stage Premium Alkaline Reverse Osmosis System connects directly to your kitchen faucet with
no plumber needed. It’s an ideal portable solution for apartments, homes, RVs, aquariums, and travel — delivering clean,
great-tasting alkaline drinking water.
Reverse osmosis (RO) uses a semi-permeable membrane to remove dissolved solids and contaminants from water by applying pressure
and forcing water molecules through tiny pores. This multi-stage process provides a higher level of purification than
traditional filters.
1) Sediment Filter (5 Micron)
Removes dust, sand, rust, and other large particles to protect downstream filters and extend system longevity.
2) Activated Carbon (T28)
Premium carbon reduces chlorine, taste & odor, VOCs, and many common chemicals found in tap water for cleaner, better tasting water.
3) RO Membrane
High-rejection reverse osmosis membrane removes the majority of total dissolved solids (TDS), heavy metals, and many harmful contaminants.
4) Post Carbon Filter (T33)
Final carbon polishing stage improves taste by removing any remaining trace taste or odor.
5) Alkaline Mineral Filter
Adds beneficial minerals and increases pH to produce alkaline drinking water with improved taste and mouthfeel. These minerals help gently
raise the pH level for balanced water.
Both membrane options deliver excellent purification quality. A 150 GPD membrane produces water faster based on feed pressure
and temperature, while the 100 GPD membrane offers reliable performance for standard usage.

After a break-in period (about 4–7 days of use), this system delivers noticeably cleaner, smoother water.
RO systems produce purified water at a slow, drip-style rate — typically about 1 gallon every 14–24 minutes depending on membrane size,
pressure, and temperature.
We recommend collecting purified water ahead of time to ensure you always have supply available.
Approximate filtration accuracy: ~0.0005 microns

This system can be connected using the included or optional adapters, allowing flexibility for many faucets:
Actual performance and filter life vary with water quality, usage, and other conditions. Routine filter replacement ensures optimal
performance over time.
