The most outstanding water purifier technology line

On the market today, there are prominent two lines of water purifier technology, RO and Nano water filtration technologies.

RO filtration technology

RO is a line of water purifiers that was born very early, but up to now is an effective and thorough water filtration technology with reverse osmosis membrane. RO technology is mainly used for salt water or hard water, this technique requires electricity to clean water and produce a lot of waste water.


  • Can drink water immediately after filtration extremely quickly and conveniently;
  • There is often a mineral supplementing core, which adds sweetness and oxygen to the filtered water;
  • RO membrane is capable of self-cleaning when filtering water;
  • With water pump, suitable for places with low water pressure;
  • The cost of replacing filter elements is quite low.


  • Do not retain natural minerals that are good for the body in water if the machine does not use additional mineral filter elements;
  • Depending on each manufacturer, each product will have purified water and wastewater filtration rates. For example, 10 liters of raw water will filter 3-5 liters of pure water;
  • Using electricity, inconvenient if power outages for a long time about 1-2 days.

NANO filtration technology

Born after RO water purification technology, Nano water filtration technology has the same structure with water filter to help eliminate bacteria and viruses. However, this filter is larger than the RO filter so the amount of minerals and heavy metals removed is lower.

Therefore, the quality of water filtered through Nano technology depends a lot on the water supply for this filter. Usually the source of treated water, the underground water has been filtered, …


  • Can drink water immediately after filtration extremely quickly and conveniently;
  • Retain many natural minerals good for the body, perfectly suitable for families with children and the elderly;
  • No need to use electricity, no waste water;
  • Does not consume electricity as well as save water efficiency for the family;
  • The machine does not use pressure vessels so extremely compact, making it easy to install in any position of the home.


  • Osmosis type filter, screen size is about 5-1 micron so it will not filter effectively;
  • Operation without pump, filter mainly thanks to the pressure of the inlet water source, so if the water is weak, it cannot filter;
  • Core replacement time is faster, core replacement cost is higher than RO filter;
  • Being limited when filtering many water sources such as alum, brackish water … filter clogging easily;

Choose to buy RO or Nano water purifiers

Sure, if your family or company is in need of a water purifier, you might be wondering whether to use a Nano or RO technology? If so, continue reading the following:

According to a lot of information on the Internet, depending on various factors you can consider the choice between RO or Nano water purifier: Brand, Warranty, Maintenance, … and a special concern for water purifiers to be able to operate in a stable and stable manner, the input water quality must be guaranteed.

  • With RO technology: Support to filter almost all water sources (if the water is contaminated with alum, acid, … it is advisable to use a raw filter before putting in the machine).
  • With Nano technology: This type is quite picky about the input water and it does not filter sources of water contaminated with alum, well water, … untreated.

Thus, through the above information, I believe that buying a water purifier using RO technology is the most reasonable and this is also the advice of the specialized sales sites available on the market.
