Abducted, squatting the people, burying the people, turning the people, deceiving the people, and seeing what happened to the body of the water purifier.
Nowadays, I can often see some water purifiers for cabbage prices, so buyers often don't understand how the brand water purifiers on the market sell so expensive. In the end, what are the "cores" for those cheap water purifiers?
Let's talk about the "core" of the water purifier, which is the filter element of the water purifier. The filter element is the main component of the water purifier. If we want to know what brand of water purifier is good, we must first look at the quality of the filter element. A good filter can cost hundreds of pieces, which may be expensive for ordinary families. Therefore, some people may ask: Is there a water purifier that does not need to change the filter?
Is there a water purifier that does not need to change the filter?
The water purifier filter must be replaced. The water purifier that does not need to change the filter element does not exist. Just, different filter cartridges, the replacement time is not the same. Nowadays, some filter cartridges on the market claim to be replaced in 5 years. In fact, some boastful flavors are inside.
Generally, household water purifiers use filter elements such as RO reverse osmosis membrane, ultrafiltration membrane, PP cotton filter, and activated carbon filter. Among them, the fine filter PP cotton filter and activated carbon filter, the replacement time is about 3 to 6 months; and the core RO reverse osmosis membrane and ultrafiltration membrane can generally be used for 2 to 3 years.
In addition, the quality of the water influent water and the frequency of use of the water purifier will affect the life of the filter.
Why should the water purifier replace the filter element?
That is because the water purifier filter separates the impurities in the water and releases clean water. The impurities blocked by these filter elements can not be completely rinsed after being washed. After a long time, the impurities will accumulate more and more. . In fact, the water purifier that will be blocked is a good water purifier, which is a good filter, which proves that it plays a role.
So, is there a water purifier that does not need to change the filter? The answer is: no. However, we don't think that the filter is expensive, we don't buy water purifiers. We buy water purifiers for drinking and cooking. We can use good water, so it is worthwhile to spend some money on the filter.
The harm of cheap filter
There are many cheap water purifiers on the market. In fact, the filter has a "track", cut corners, and shoddy. Take the pellet carbon and PP cotton as examples. We all know that pellet carbon has many different raw materials, which is better. The import of coconut shell carbon, but many businesses will use coal-based carbon, or common fruit and shell miscellaneous materials mixed together, large size, poor adsorption capacity, less grams, low iodine value, can not play the national standard purification, and even It also releases substances harmful to the human body. PP cotton is used as the first filtration, and the process is also divided into flat winding and progressive progressive winding. The number of grams is divided into 100g/120g/130g, etc., which will cause the first stage of filtration, poor PP cotton can not effectively isolate the pollutants. Let the pollutants directly enter the filter element behind, causing the filter element behind to be quickly contaminated! The water purifier using the inferior filter element can not only guarantee the safety of the user, but instead adds a sewage device to the filter. Water has formed "secondary pollution" and long-term drinking has seriously affected the health of family members.
For the health of you and your family, it is recommended that you consider installing a water purifier to address the health of the source of life.
