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 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.
