Because people who have never used a water purifier think they can live well and healthily without this thing. People who have used it have not seen its most substantial changes, and feel that the water purifier has not changed much in life. So most people will think that the water purifier is a scam.

Some people think that the water purifier is a scam, mainly because the water purifier industry is not transparent enough and the water is deep. There are mainly four kinds of water purifiers on the market. The first kind of water purifier is called waterway protector, which mainly filters some relatively large impurities, such as sediment, rust and other large particles. If slag accumulates too much, it will do harm to human body. This water purifier can also protect household appliances that need water.

A kind of water purifier beneficial to human body is called ultrafiltration machine, which mainly filters some bacteria and colloids, as well as some harmful substances of macromolecules. In this way, people can avoid diseases caused by drinking sewage. The third kind of water purifier is called water softener, which uses ion exchange to remove calcium ions and magnesium ions from water. The last one, the reverse osmosis water purifier, is the highest-end water purifier on the market now, and its function can make the water basically reach the level of pure water.

In order to promote the water purifier, many merchants exaggerate its efficacy and even blow it to the point where it can cure diseases and preserve health. What's more, they spread rumors everywhere. Now the drinking water is not clean and the impurities exceed the standard. It has caused some elderly people who don't know the truth and people with low education level to panic, plus going to the countryside to sell some unqualified water purifiers. It has ruined the reputation of the water purifier industry and made many people think that the water purifier is a scam.

Therefore, the essence of the water purifier is not a scam, mainly because some people cheat, and they leave a bad impression. Water purifier is something that families with conditions can consider buying, and families without conditions can basically drink bottled water. If you really have no conditions, you can consider boiling water directly before drinking. If you want to buy a water purifier, don't believe in the efficacy, you must polish your eyes.
