5 Factors to Consider When Choosing a Water Purifier
1. Filtration Technology
The first and most important factor is the quality of filtration , since each water purifier uses a different technology, such as Reverse Osmosis (RO), Activated Carbon, UV, UF and Hollow Fiber Membrane
Cleansui uses Hollow Fiber Membrane technology , which can filter out germs, bacteria, viruses, and tiny contaminants down to 0.01 micron while retaining the minerals that are good for your body. Unlike RO systems, which filter out everything, water filtered by Cleansui keeps its natural, healthy taste.
2. Contaminant Removal Performance
Cleansui can filter out up to 13 types of contaminants , including chlorine, lead, mercury, cadmium, and chemicals that are harmful to health. It is also certified to the NSF (National Sanitation Foundation) standard in the United States, confirming that Cleansui’s filtration system is of the highest international quality.
3. Retaining Beneficial Minerals
Unlike RO water purifiers, which remove all minerals, Cleansui water purifiers retain beneficial minerals such as calcium, magnesium, and potassium, so your water keeps its nutritional value instead of being plain water stripped of nutrients.
4. Easy to Install and Use
Cleansui water purifiers come in a wide range of models, including faucet-mount (EF Series) and under-sink (EU Series) models that are easy to install, with no wall drilling and no electrical hassle.
No costly upkeep: Cleansui filter cartridges are long-lasting and easy to replace.
5. Long-Term Value
With outstanding filtration quality, Cleansui helps you save on the cost of bottled water. On average, a Cleansui water purifier can run for many months without frequent cartridge changes, which also cuts plastic waste and helps protect the environment.
