Today, I will explain it to you once and for all. First of all, let’s take a look at the mainstream water filters on the market. The filtering accuracy is classified from low to high.
First, the pre-filter.
It has an average filtering accuracy of 10 to hundreds of microns, which can remove large particles, such as mud, sand, rust, insect eggs, etc. Its main function is to protect all water equipment in your home from being polluted by large particles, including water heaters. Shower, faucet, etc.
The second category is ceramic water purifier.
Generally, it contains ceramics and carbon rods. The filtration precision can reach the level of 100 nanometers. It can remove most bacteria, viruses, residual chlorine, odor, etc., but can not remove ions in the water. In theory, it can be directly drunk, but the boiled water will generally have scaling.
The third category is ultrafiltration water purifier.
Generally, it includes pp cotton, activated carbon and ultrafiltration membrane. It does not need to plug in electricity or discharge waste water. The filtration precision can reach the level of 10 nanometers, which can remove smaller bacteria and viruses. Of course, it can also remove residual chlorine and odor, but it cannot remove ions in the water. In theory, it can be directly used for drinking, but the water will generally have scaling.
The fourth category is nanofiltration water purifier.
It generally includes PP cotton, activated carbon and nanofiltration membrane, which need to be plugged in and drained, and the filtration accuracy can reach the level of 1nm. It can selectively remove ions, with relatively low removal rate for low valent ions, such as potassium and sodium ions, relatively high removal rate for high valent ions, or high molecular weight ions, such as calcium, magnesium, heavy metal ions, etc., which can remove harm and retain benefits. In theory, it can also be directly drunk, and the boiled water generally does not scale.
.
The fifth type is reverse osmosis water purifier, namely RO water purifier,
which generally includes PP cotton, activated carbon and RO membrane. It also needs to plug in electricity and drain waste water. Please remember, this is a more intuitive method different from the ultrafiltration water purifier. Its filtering accuracy can reach the level of 1 nanometer, which can remove most of the ions, including potassium, sodium, calcium, magnesium, heavy metal ions, etc. In theory, it can also be directly drunk, and the water will not scale.
How to choose? Here are my suggestions for you.
First, if your home does not use tap water, there is no industrial pollution, there is no high incidence of water related diseases nearby, there is not much scale in boiling water, or you do not care about scale at all, it is not recommended to install a water purifier.
If not, it is recommended to install a RO water purifier.
Second, if your home uses tap water, and you are in the downstream of the river or worried about industrial pollution, scale is relatively serious or you care about scale personally, then install a RO water purifier.
If not, ceramic or ultrafiltration water purifier can be installed.
If the house is newly decorated or the installation conditions permit, a prefilter can also be added, preferably with a backwash function.
Finally, no matter what water purifier we install, we’d better choose one with brand and after-sales service, so that the product is more guaranteed.
I also don’t suggest that you drink it directly. You should boil it and drink it. Don’t ask me why. Also, you should buy the nanofiltration water purifier carefully, because there are too many fraudsters. I’m afraid you will be trapped.
The above is my suggestion for installing the water purifier. OK, let’s talk about it today. If you think I’m right, I suggest you like it and share it with people in need. Pay attention to the water purification brother, clean water does not step on the pit, so that the family can drink more at ease, thank you!
