The purpose of installing the pre-filter and the water purifier is to purify the water quality, but because the accuracy of the two filtration is different, the installation position is different, the water flux is different, there is no conflict in the function of the two, and there is no need to install the pre-filter problem of installing the water purifier. More importantly, the pre-filter has three advantages that water purifiers cannot replace.
First, large flux, the whole house water purification without burden
The filtration of the water purifier is fine, but the filtration speed is slow, which can only meet the needs of drinking water. A small front filter can meet the needs of sanitary water in the whole house. The flux of the pre-filter on the market is generally between 2T-4T, which is basically competent for the normal water use scenario of any home.
2. Protect other household wading equipment
The pre-filter is usually installed on the water inlet main pipe, which can reduce the impurities in the pipes in the home, so that the faucet, shower, etc. will not affect the amount of water due to the blockage of impurities. Filtered water is also more reassuring for washing, laundry, and washing dishes. It is more important to protect wading equipment such as washing machines, dishwashers, water heaters, and water purifiers to ensure their normal service life.
If there is no pre-filter, then the work of filtration must be undertaken by the water purifier. This will inevitably affect the service life of the water purifier filter, and it is also a big expense to replace the filter element frequently.
Third, one installation, once and for all
The service life of the filter element of the water purifier is generally 3-6 months, while the pre-filter is filtered by the pressure of tap water, and it is made of stainless steel, which is corrosion-resistant and durable, and does not need to change the core for life. The valve head of the Paikang pre-filter is made of fine copper, bacteriostatic and antioxidant, and there will be no precipitation of heavy metals; The housing is made of transparent PC material, which is durable and visible, which is convenient for timely detection of impurities on the filter element, disassembly and washing, without any consumables.
The cleaning methods of the pre-filter are direct punch, recoil, siphon and laminated flushing, among which the backwash mode used by the Paikang pre-filter is more recognized. The automatic cleaning ability is strong, and impurities can flow out through the sewage outlet below, reducing secondary pollution.
In general, the pre-filter is installed to intercept impurities generated or carried during tap water transportation, and to restore tap water to factory standards, in other words, to improve the quality of water in the whole house. Generally, the filter accuracy of the pre-filter is 40-80 microns, such as the Paikang pre-filter using a 40-micron stainless steel filter, which can intercept impurities such as sediment, rust, algae, detritus, etc., improve the turbidity of water quality, rust smell, thick scale at the bottom of the kettle, water heater is always blocked and other issues. Water purifiers are installed to improve the quality of drinking water. The water purifier can filter out heavy metals, bacteria, viruses, etc., so that the filtered water can meet the standard of direct drinking.
