Is it necessary to install a pre-filter? I have used it for 3 years, talk about my experience

Water is the source of life. The current drinking water environment is getting worse and worse. Large particles such as sediment and rust are often found in tap water. In order to improve the quality of tap water, many people will consider installing a pre-filter in their home. However, I often see some decoration bloggers on the Internet saying that pre-filters are IQ taxes. Not only can it fail to meet the drinking water standard, but it may also cause secondary pollution. But friends who have used it say that the pre-filter is still very practical. When I was renovating my house, I also struggled for a long time, should I install a pre-filter? Later, with the attitude of giving it a try, I installed one. The price is not expensive. It is only a few hundred meters, and it is still affordable. Now that I have been using it for 3 years, talking about the experience of using it, I find that it is more and more inseparable from it.

1. What is a pre-filter?

Before we decide whether to install or not, we have to figure out what a pre-filter is. The pre-filter, as the name suggests, is the equipment installed at the forefront of the water in the whole house. It is the first barrier for water in the whole house. Through a metal filter with an accuracy of about 40 microns, it intercepts large particles such as sediment, rust, and aquatic plants in the water.

Second, the role of the pre-filter

If the tap water is turbid, the water can be made clear with the help of the pre-filter. Its main function is to improve the quality of tap water visibly to the naked eye and ensure the health of drinking water and water. Because the filter screen of the pre-filter is relatively thick, it can only intercept impurities of large particles. But its role is also very large. It intercepts large particles such as sand and rust, so there is no need to worry about these large particles entering water heaters, washing machines, floor heating, wall-hung boilers, and water purifiers. In this way, it can effectively protect these electrical appliances, reduce sediment deposition, and prolong the service life. If the faucet with a ceramic valve core is used at home, once the ceramic valve core enters the sediment particles, it may cause the valve core of the faucet to be scrapped. At this time, the effect of the pre-filter is reflected.

Three, effectively solve the problem of scale

The main components of scale are calcium and magnesium. If the scale is not cleaned for a long time, it will not only damage household appliances and water pipes, but also will affect the body. Because the pre-filter can intercept large particles such as sand and rust in tap water, it just solves the problem of scale in tap water.

Fourth, the location must be correct

The pre-filter should be installed at the front end of the water pipe in the whole house, such as the water meter and the entrance gate. Front. Some people install it under the kitchen sink so that it only works on the sink, and of course it becomes tasteless.

V. Installation time

The installation time of the pre-filter also needs to be paid attention to. Generally, the installation will only be carried out after the hydropower enters the site for the pressure test. It is best to buy the pre-filter in advance, and then communicate with the water and electricity master in advance to reserve the installation location.

Six, how to buy a pre-filter

The stainless steel filter element of the pre-filter is mainly divided into 304 and 316, of which 316 is medical grade stainless steel , Corrosion-resistant, safer and more hygienic. If you buy a pre-filter, it is best to choose a 316 filter element to avoid secondary pollution. For the main body of the filter, it is better to choose lead-free copper or lead-separated copper, which is safer and more secure. The filtration precision is about 40 microns. Although it is said that the finer the filtration, the better the filtration effect, but if it is too fine, it is easy to cause the filter to block and affect the water output. It is best to choose the backwash mode for the filter screen, and add the double-sided scraping function, double-sided scouring and double-sided scraping, so that the washing can be done with half the effort. If the water pressure is relatively large, the explosion-proof function is preferred.

Seven, it is best to install it with a water purifier

The reason why some decoration bloggers say that the pre-filter is an IQ tax is mainly because it cannot Tap water is purified to drinking water standards. This is really difficult for a strong man, no matter how good a chef is, there is no way to cut carrots into diced meat. The function of the pre-filter is to achieve basic filtration, and a water purifier is responsible for purifying water quality. If you want to meet the drinking water standard, it is best to match the RO reverse osmosis water purifier. The pre-filter filters out the large particles in the water, which can effectively reduce the pressure of the water purifier, avoid clogging and prolong the service life of the water purifier. Then the water purifier purifies the heavy metals, bacteria, viruses, microorganisms, disinfection water and other pollution in the water, and finally reaches the standard of direct drinking water.


Pre-filters are inexpensive, but they can make muddy water clear. It is really cost-effective to filter out large particles of impurities and protect the faucets, showers, washing machines, dishwashers, water heaters, floor heating, wall heating, water purifiers and other equipment in the home to a large extent.
