As a more advanced way of healthy drinking water, household water purifiers and pure water machines are gradually entering thousands of households. As a professional manufacturer of household water purifier filter cartridges (PP melt blown filter cartridges)
When buying a water purifier, it is necessary to strictly follow the recommended time in the manual or replace the filter element regularly for a period of six months, otherwise it will cause secondary pollution, which not only cannot purify but also is harmful to the body. Don't let the water purifier age too early, regularly maintain or replace it.

The water flow not only contains sediment, but also bacterial clusters and sediments from the water pipeline. Although the water plant has undergone disinfection treatment, the flow of tap water in metal pipes still generates secondary pollution.

With the emergence of water dispensers and bottled water, people's drinking water safety has been significantly improved to a certain extent. However, with frequent problems in the quality of bottled water, secondary pollution caused by long-term non cleaning and mold growth of water dispensers, people are gradually turning their attention to trusted water purifiers. The characteristic of water purifiers is that they achieve terminal water purification, and the market was once booming, but are water purifiers really useful?

1. Is water really dirty? What can various water purification equipment purify?
The common water filtration methods in the market include microfiltration, ultrafiltration, nanofiltration, and RO (ultrafiltration and nanofiltration are often referred to collectively as ultrafiltration), corresponding to the following substances that may be contained in tap water. The filtration capacity is shown in the table below:

Imagine different impurities as fish of different sizes, and different filtering methods are fishing nets with varying pore sizes. The expression based on pore size is shown in the following figure:

So, to solve different water quality problems, it is necessary to choose corresponding equipment.

2. Types of water purification equipment
(1) Pre filter
Installed at the front end of the home's water pipeline (behind the water meter), this device is a coarse filtration device used to filter large particles such as mud and sand, in order to protect the water purification equipment and shower heads in the back. The filtration accuracy of 90-110 microns is sufficient. If it is too small, it is easy to block. The pre filter for backwashing is easier to clean the filter.
Advantages: No need for dedicated after-sales service, no need to replace filter elements, intuitive and transparent filtration effect (clear observation of filtration effect and usage status), long service life (up to several decades).
Disadvantage: Only coarse filtering is possible.

(3) Reverse osmosis water purifier (RO machine)
The filtration accuracy of the RO membrane can reach 0.0001 micrometers. In addition to being able to filter through ultrafiltration, it can also remove ionic impurities, etc. Basically, it can only allow water molecules to pass through the RO membrane.
Advantages: Strong purification ability, good effect, and can basically meet the standard of pure water.
Disadvantages: Low water yield can cause water resource waste and high cost.
