  • Well water: 

There are currently very few types of filters that can meet the quality of the output water as well as the life of the filter. It depends on the level of heavy or light water pollution. Many families have installed a filter to get water samples tested for qualified water. But maybe only the next day, a week later or a month later, the water quality has changed because the filter core is not eligible to meet the contamination of well water. 

The only treatment is that you have to roughen the water before putting it into the filter by building a multi-storey filter tank, including black sand, yellow sand, activated carbon, then depositing and then going through a water filter to drink. Although expensive, in return, you will have guaranteed water to use. If your family does not have conditions to build a filter tank, you can use rainwater to filter.

For the current RO series, there are many RO filters: RO Filmtex of Kangaroo, Sunhouse, and RO Aqalast of Karofi. However, Karofis RO AQUALAST ™ 1812 filter is more outstanding in its ability to handle diverse water sources and water quality up to QCVN6-1 / 2010 Ministry of Health Te.

Aragon of Geyser, USVR-AquaVallis of Sunny-Eco, and some other Nano cores of Nano Sky and OhiDo, among these technologies, are Aragon and USVR-AquaVallis. However, Aragon is more outstanding in ability, persistent and bactericidal.

  • Disadvantages of Nano water purifier :
