5 Stage MyAquaFilter Countertop RO system with Alkaline or Mineral stage 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  gallon 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: Standard T33 coconut shell activated carbon filter. The last stage removes any potential remaining unpleasant taste.
  • 5th stage. Option 1. 3-in-1 Alkaline, ORP and Tourmaline media filter. Increase pH level to 8.5-9.5. Filter contents 3 different media. Tourmaline (also known as Magic Stone) natural gemstone is a semi-precious mineral stone well known for its incredible ability to aid in the detoxification process of the human body. Studies have shown the increased incidence of chronic disease is directly related to toxic overflow in the body. Tourmaline gemstone is known to aid in relieving stress, increase mental alertness, improve circulation and strengthen the immune system. Far Infrared Rays and negative ions gently heal, soothe, stimulate and detox the body. ORP media reduces water Oxidant Reduction Potential to -50mv~-150mv. Enrich pure water with minerals (Calcium, Magnesium, Sodium, K, P, Zn, etc).  Option 2. 4-in-1 Mineral media filter: tourmaline, FAR infrared, mineral and maifan stone. Release soluble essential minerals back into water such as Calcium, Magnesium, Sodium, K, P, Zn, etc. Restore mineral balance after Reverse Osmosis filtration Increase amount of dissolved oxygen. Only natural media from stones. Raise pH level to 8-8.5

Our Universal Alkaline 5-stage RO system is the best RO Water Purification System for water treatment and remineralization. This Reverse Osmosis Purification System delivers approximately 3-6 gallons of pure water per hour. Our 5 stage Reverse Osmosis Water Purification System is the best fit for water treatment in areas with mild or hard water supply (TDS level above 100-300ppm). Removes more than 220 different hazardous contaminants from the water. RO removes between 90% to 98% of fluoride.

What to expect.
  • If your tap (source) water is around 300 ppm, after the last stage Alkaline filter – 35-65 ppm in TDS and around 8.5-9 in pH. If you choose RO with Mineral post filter 25-55 ppm and 8-8.5 pH.  The test needs to 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 to choose Reverse Osmosis system.

The heart of any RO purification system is 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).

    I would highly recommend this RO to customers. It reduced the dissolved solid content in my apartment tap water from 350+ to 30 within 2 hours after installation. Good solution for those who are buying water from supermarket. This will save money and time.


  2. Leonid

    I would highly recommend this filter to customers. It reduced the dissolved solid content in my apartment tap water from 300+ to 45 within 4 hours after installation. Good solution for those who are buying water from supermarket. Save your money and time as well.


  3. Joshua

    Tasty water for apartment people. I am 100% satisfied with the water and taste better. The water filtering was decent fast. Value for money.

    I received this 5-stage countertop RO system as a gift, and it has exceeded my expectations in terms of water purification. It effectively reduces the TDS (total dissolved solids) from 750 to 60, ensuring a remarkable level of cleanliness. Initially, I had concerns about the pH level, as my pH reader indicated that the RO water was around 6-6.5. However, the customer service representative I contacted was outstanding. They promptly addressed my concerns by sending me an alkalizing filter and a pH meter, completely free of charge. After replacing the last filter with the one they provided, I noticed a definite increase in pH.

    One of the advantages of this system is its compact size, taking up minimal space on the countertop. Additionally, the installation process is incredibly easy, and replacing the filters is a breeze. Considering the affordable price point, it offers exceptional value for achieving completely purified water. The taste of the water is fantastic, comparable to, if not better than, bottled water. I wholeheartedly recommend this RO system. Not only does it provide peace of mind by offering safer water compared to systems with under-sink tanks, but the company behind it also delivers a great buying experience.

    This is the perfect unit for a condo/apt – even for an aquarium!

    I was actually buying water from local grocery store, it was 0.40 cents per gallon, not bad. Until one day I bought a TDS meter and realized that my RO from grocery was virtually the same as tap water. It even tasted like tap water, I was paying 40 cents a gallon for tap water, what a rip off. Then I went to Safeway. Their machine showed a TDS of less than 50 PPM and it tasted great, but cost 50 cents a gallon. Then their machine broke, and all they sold were 5 gallon jugs for $7.50. So I was paying over a dollar a gallon for drinking water. So in a little over 2.5 months I was paying about what this water filter cost.

    If you buy this filter you for sure will need a TDS and PH meters. When you first start it up the TDS will be sky high until it flushes itself out and the timing on that depends on your water pressure. Start collecting water when it gets below 45 PPM. Seems like the longer you run this filter the lower the number gets and the better the water. But when you start it back up the numbers are high again for the first 20 minutes or so, I drain that off before I collect it.
    Whatever you do, don’t ever drink your tap water no matter how good you think it is. I’m a retired chemist and let me tell you that there is no way to test your water for everything. Most water tests will only test the basic few parameters. For a wide spectrum of compounds you would need to spend thousands of dollars in various tests, and even then you could be contaminated with a new designer drug or something that will bypass the tests and they would never detect it. What you really want is RO water, but not with a TDS of zero, you want minerals added back. This system is the best I’ve seen, it will remove all compounds and minerals and then add back just enough to make it taste good and 100% safe.

    I really love this system. I have been using it approximately for 1 week. It is very easy to connect to the faucet. I read the manual that test needs to be done after 20 gallon of water passing through the system. I was able to test today. Originally my tap water TDS was 340ppm, after filtration it’s 45 ppm, pH 8.6 is little higher then I expected (my target was pH 8.5-8.7) but I cool with it. I’m happy with purchase.
