Pre-filter is a reliable impurity filter, can filter more than 40μm of particulate impurities, make the water quality back to the factory standard of tap water, prevent water pollution, avoid pipeline corrosion.

As a coarse filter, the prefilter can protect the filter core of the subsequent water purifier and extend the service life of the terminal water purifier product.Without the protection of pre-filter, the purifying system can quickly clog up.

Pipeline corrosion, sediment and other impurities will not only lead to the failure of brown water and water equipment control parts, such as faucet dripping, heat exchanger pipe blocking, rupture, and it also will precipitate down in the pipeline.On the one hand, they provide a breeding ground for bacteria, and on the other, they form electrochemical substances that can corrode or perforate metal pipes in just a few months.

The pre-filter is the first coarse filter device for the whole house water, usually installed behind the inlet pipe water meter. Can filter tap water in the sediment, rust, large particles.Ensure that the large amount of precipitate impurities produced in the pipe network will not cause harm to human body, and play a positive role in protecting the concealed laying, water pipes and household appliances.
