Why are there so many grades of water purifier filters?

The filter elements of water purifiers on the market generally have levels 3, 4, 5, and some even have levels 6, 8 and so on. This makes many consumers wonder whether the higher the level of the filter element, the higher the filter level of the water purifier. The better the effect? Why are filter elements divided into so many grades? In fact, if you think so, you would be wrong. The reason why water purifiers need multiple filter element combinations is that they need to purify and intercept harmful substances in tap water layer by layer, such as heavy metals, bacteria, viruses, sediment, rust, etc., and different filter elements have different functions.

The first-stage filter element: PP cotton; it can filter out large particles in the water, such as rust, sand, colloidal substances, algae, etc., as the first barrier, which intercepts large substances and has a relatively short life span, generally 3 months The left and right need to be replaced once.


The second level filter element: activated carbon filter element; this kind of filter element has strong adsorption capacity, mainly for gas pollution, such as residual chlorine and chemical residual gas, generally replaced once every six months

The third level filter element: ultrafiltration membrane; this filter element is generally used in ultrafiltration water purifiers and reverse osmosis water purifiers. The purification accuracy is better than the first two filter elements. It can intercept substances with a precision of 0.01 micron or more in tap water. After the tap water can be used to wash vegetables and cook in the kitchen at home, it is recommended to boil for drinking.

The fourth-stage filter element: RO membrane filter element; this filter element has the highest filtration accuracy of all filter elements, up to 0.0001 micron, and it is no problem to remove tiny heavy metals and bacteria in the water.

The fifth level filter element: taste factor filter element; the main function of this filter element is to improve the taste of water and inhibit bacterial regeneration, or it is called a post activated carbon filter element. The life of this kind of filter element will be relatively longer, about once a year to replace.


These filter elements are arranged and combined according to their own functions to purify water quality, but this does not mean that the higher the filter element level, the better the water purifier. This is because if there are too many filter elements, it will increase the subsequent use cost, because the water purifier itself can be used repeatedly, and the filter element needs to be replaced.

However, in order to save consumers' filter replacement cost, most water purifiers have been simplified into two-stage, three-stage or four-stage filter elements. The function is not reduced, but the composite filter element is developed using composite technology to cover a variety of filter element functions. For this reason, when choosing a water purifier, don't be fooled by some superficial phenomena.

Quality of water purifier filter element:
Among the brands of water purifiers, what are the filter elements used by various manufacturers and what is the quality?

It mainly depends on which water purifier you are using. The main supplier of the 2008 Beijing Olympic Games water purifier is considered to be the industry's top product mainly using Guangzhou Lvyuan Water Purification Equipment Co., Ltd. PP cotton activated carbon ultrafiltration The quality of the activated carbon filter element behind the membrane is considered good.

However, its product reviews are neither good nor good. Founder does not have technical products, as long as the materials are good, they are basically the same. The main filter element materials are: Guangzhou Lvyuan Water Purification Equipment Co., Ltd.pp cotton, activated carbon, ultrafiltration membrane. The material is pretty good.


Which is the best water purifier filter?

Ceramic filter elements, PP cotton and the like belong to the primary filter, and are the filter materials of some simple water purification equipment. If we choose according to our current standards, we will definitely choose higher standards and better filtration effects, so there are ultrafiltration membranes and reverse osmosis membranes, which have better filtration effects.
