4 Stage MyAquaFilter Countertop RO system has following stages:
  • 1st stage: Premium Quick-Connect 5 micron sediment filter. Dust and rust particles are trapped here in the filter which also extends the life of the RO system and the membrane.
  • 2nd stage: Premium USA made Quick-Connect T28 coconut activated carbon filter – VOCs (volatile organic compounds) and other common chemicals are removed from the water in this stage. This filter removes chlorine, chloramine, pesticides and herbicides, benzene, trihalomethane (THM) compounds, radon, solvents, and hundreds of other man-made chemicals found in tap water,  This stage removes offensive odors, colors, and unpleasant taste.
  • 3rd stage: Premium High Rejection TFC type Reverse Osmosis membrane (membrane made in USA).  96%-98% of total dissolved solids (TDS) and other elements are removed in this stage. Arsenic, fluoride, lead, chromium, radium, viruses, bacteria, aluminum, cyanide, methane, silver, copper, chromium, strontium, uranium, benzene, nitrates, cysts, radium. cloudiness and other unhealthy contaminants are removed from the water. 75 or 150 gallons per day capacity (it takes approx 22 minutes to get 1 gallon of pure water for 75 GPD membrane, and 11 minutes – for 150 GPD membrane).
  • 4th stage.  Option #1. Standard T33 coconut shell activated carbon filter. The last stage removes any potential remaining unpleasant taste.  Option #2. Premium Antibacterial KDF-55/T33 Omnipure Made filter. We recommend this filter during travel time or if you do not plan to use RO system regularly.

This Reverse Osmosis Purification System delivers approximately 3-6 gallons of pure water per hour. Our 4 stage Reverse Osmosis Water Purification System is the best fit for water treatment in the areas with fairly clean municipal water supply (TDS level in the range of 20-300). Removes more than 220 different hazardous contaminants from the water.

What to expect.
  • If your tap (source) water 300 ppm, after filtration – 20..46 ppm (test can be performed not earlier than 4-6 days of regular use).
  • RO System dimension: 14″x6″x6″.
  • This RO system produces 1 gallon of water every 11-22 min (very slow, water purification output depends on membrane GPD rating, water dripping not flowing). We highly recommend collecting water in advance (every day or every second day) to always have it on hand. Don’t be surprised, Countertop RO systems purify water 8-10 times longer than a regular water filter.
  • Every RO system in the world split water into 2 flows pure and waste water. The ratio is 1 part of pure water for 2.4 parts of waste water. This is how Reverse Osmosis technology works.

Why choose Reverse Osmosis system.

The heart of any RO purification system is a reverse osmosis membrane. RO membrane splits water with 0.0005 micron filtration, approx 1000 times more effective than any water filter without RO membrane (see picture below).

    Great product wish I had purchased it earlier

    I received this at the end of July 2020, and have been using it for all my drinking and cooking water. Out of the box, it was putting out water at 2ppm on a municipal water supply that was around 243 ppm. It’s currently January 2021, and that’s when I took the picture. It is still producing excellent water at 2 ppm.

    It’s a one person/one cat household, but several times I have accidentally left it running all night long wasting gallons of water. So my usage is probably a normal three person family. Takes about 28 minutes to fill a gallon. I Just set a timer now so I don’t forget.

    It is super easy to install, sometimes I’ll just leave it hooked up and use the bypass valve. But it’s stores neatly on the shelf above my sink when not in use. I will update this review before it’s time to replace the filter.

    Well worth the money, it will save you hundreds of empty plastic bottles and lugging cases of water around, or buying filters that really don’t perform anywhere near the level that this filter does. My goal was to remove the poisonous fluoride & lead in my municipal water supply, and this gets that out along with nearly every other particulate matter. Cheers!

    I am genetically modifying plants and growing them via hydroponic (dwc) garden the PPM is a constant 23 ppm once you pump the first gallon or so through. If you are looking for a portable filter this is definitely the one. My water tests at around 240 ppm here at the house so my waste was about 3:1. The shipping was very fast.

    Works very slow , but it is ok…

    Excellent unit. RO unit is truly an outstanding water filter option, especially considering its unbeatable price. I purchased this unit several months ago, and I occasionally check the ppm levels approximately once a month. During my last check, the ppm reading was an impressive 12. This level of filtration is truly remarkable. To ensure its continued performance, I do recommend investing in a TDS (total dissolved solids) pen. This handy tool allows you to monitor the effectiveness of the system over time and keep an eye on its ongoing performance. It’s a worthwhile addition to maintain confidence in the quality of the filtered water.

    Yummy! MyAquaFilter Countertop RO unit is an excellent choice for those who are tired of constantly purchasing short-lived water filter pitchers for their fridge. However, there are a couple of minor improvements that could enhance the user experience. Firstly, I believe the hoses should be longer, as once the system is attached and in place, your faucet becomes somewhat restricted. Additionally, a true quick connect feature would be beneficial. When it comes to taste, the Countertop RO system delivers delicious water. Even if you leave it out overnight, the water retains its refreshing flavor and doesn’t develop the unpleasant taste that is often associated with other filtered waters. This is particularly noteworthy for those, like myself, who keep a glass of water on their nightstand and dislike the taste of water in the morning.In conclusion, while there are a few minor improvements that could be made, the Countertop Reverse Osmosis system is an ideal alternative to short-lived water filter pitchers. Its ability to consistently provide great-tasting water, even after sitting out overnight, makes it a worthwhile investment for anyone seeking a convenient and refreshing drinking water solution.
