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 4-Stage Basic Reverse Osmosis System connects directly to your kitchen faucet and requires
no plumber, no permanent installation, and no tools.
It is an ideal portable water purification solution for apartments, homes, RVs, aquariums, and travel.
Stage 1 – Sediment Filter (5 Micron)
Removes dust, sand, rust, and suspended particles while protecting downstream filters and extending membrane life.
Stage 2 – Coconut Shell Activated Carbon (T28)
Reduces chlorine, taste and odor, volatile organic compounds (VOCs), and many common organic chemicals.
Stage 3 – Reverse Osmosis Membrane (TFC)
High-rejection RO membrane removes 95%–99% of total dissolved solids (TDS) and a wide range of dissolved
contaminants including arsenic, fluoride, lead, chromium, and other dissolved solids.
Stage 4 – Post Carbon Polishing Filter (T33)
Final carbon filtration stage improves taste and provides polished drinking water.
Both membrane options provide the same level of purification quality.
Higher GPD membranes produce water faster, while actual performance depends on water pressure and temperature.

Example TDS results:
If source water is around 350 ppm, filtered water may measure approximately 15–50 ppm
after regular use for 5–7 days following initial flushing.
We recommend collecting purified water in advance to ensure a steady supply.

Max –
I previously had a standard filtered water unit, but even after replacing the filter, the water never tasted truly clean or refreshing. I was determined to find a better solution and knew that reverse osmosis is one of the most effective technologies for removing impurities from water, so I decided to give this system a try. Installation wasn’t the simplest and does require some time and preparation. I recommend doing a bit of research beforehand and allowing yourself enough time, or even having a handyman help if needed. However, once the system was properly installed, flushed, and running, the difference was immediately noticeable.
The water quality is on a completely different level. You can taste the improvement right away, and it even makes difference when cooking—simple things like pasta—and when watering plants. Everything about the water feels cleaner and fresher. This system truly delivers, and it’s the real deal
