In a whole-house water purification system, pre-filter is typically installed near the main water inlet of the plumbing, before other household water purification devices (such as central water purifiers, water softeners, and RO purifiers), serving as the first line of defense for household water. It performs preliminary filtration of the raw water entering the household pipes, removing larger particles, impurities, and sediment. As a result, it improves water quality and protects household water purification equipment from damage.
Equipped with a 316 food-grade 40-micron stainless steel filter mesh, it can intercept large particles, corrosion-resistant, and wear-resistant. It features a compact structure, low maintenance cost, no need for frequent part replacement, easy installation, and is suitable for places requiring high flow rates and good water quality.
5-micron big fat bottle filter cartridge is adopted for fine filtration, efficiently intercepts impurities in water, corrosion-resistant, wear-resistant, explosion-proof, and pressure-resistant. Equipped with a manually controlled four-position valve, it switches between filtration, bypass, backwash, and stop. The operation is simple, and the filter cartridge needs to be replaced regularly.
