Does the water purifier need a pre-filter?

All pre-filters are front-end devices installed in the tap water pipe, so they are also called front-end filters. However, water purifiers are different. They are installed at the terminal of the tap water, which is the place that is most directly in contact with human skin. The installation locations of the two are very different. In addition, the water purified by the water purifier can not only be used as domestic water, but also as drinking water. It belongs to fine filtration, but this must be based on the first filtration. Otherwise, the purification effect will not only be greatly reduced, but also damage the water purifier equipment. The first filtration here is the pre-filter. This filtering equipment is the first rough filtration equipment for the tap water of the whole house. It is mainly used to filter the mud, rust and large particles in the tap water. It is precisely because of the first filtration process that the water purifier can purify the water source more finely, so that the water quality in the whole house can meet the drinking standard.

Where is the pre-filter installed?

The pre-filter is installed at the water meter at the front end of the water inlet pipe.

The pre-filter is the first coarse filtration device for the water used in the whole house. It can filter out the mud, rust, and large particles in the tap water. The pre-filter is usually installed at the front end of the pipe, so it is named "pre-filter"; and "filtration" refers to the basic principle of this type of equipment. It is usually a "T" structure. The "horizontal" position above is the water inlet and outlet on the left and right ends respectively. The "vertical" position below is the body and the internal cylindrical filter screen, and the bottom end is the sewage outlet, which is controlled by a valve to open and close.

What is the difference between a pre-filter and a water purifier?

The pre-filter is called the pre-water purifier, and the water purifier is called the terminal water purifier.

1. Difference: The water purification effect of the terminal water purifier is better than that of the pre-filter, and the price is relatively high.

2. Pre-filter: Usually installed behind the water meter of the water inlet pipe to ensure that the large amount of precipitated impurities generated in the pipe network will not cause harm to the human body, and play an active protective role in concealed pipes, faucets, electrical appliances, etc. The pre-filter is the nemesis of secondary pollution and is a reliable impurity filtering device. The household pre-filter is the first coarse filtration device for the water used in the whole house. It can filter the sediment, rust, and large particles in the tap water.

3. Terminal filter: It is usually installed on the water outlet pipe or directly on the faucet to complete the final purification.
