The first line of defense for water use in the whole house ——OSWNKW - 05 Whole house pre-filter

On the road to pursuing a high quality of life, the first checkpoint of household water use is crucial. OSWNKW-05 whole-house pre-filter, with exquisite German craftsmanship, creates an indestructible water defense line for you, protecting the water health of you and your family in all aspects.
1. Accurate filtration to intercept impurities
The 304L stainless steel filter element with a pore size of 40 microns is like a fine filter guard, accurately intercepting sediment, rust, algae and large suspended particles, so that these potential "water quality killers" cannot step into the house, ensuring that every step of your home is clean. Every drop of water is pure from the source.
2. Carefully guard and extend the life of the equipment
Hidden particulate impurities in urban water constantly threaten the "health" of household pipes as well as kitchen and bathroom equipment. Faucets, shower heads, water heaters, washing machines, RO water purifiers and other water-related equipment are easily blocked and damaged by these impurities. The OSWNKW-05 pre-filter, like a loyal guardian, effectively blocks impurities, significantly extends the service life of various water supply facilities, and saves you maintenance and replacement costs.
3. Convenient cleaning, one-click easy
When the pre-filter is filled with sediment, there is no need to tediously remove all pipes and fixtures. Just turn the key to the right, the sewage ball valve will open instantly, and the scraper can be manually rotated at the same time to deeply clean the filter and easily restore its original shape. Powerful filtering performance saves your operation time and effort.
4. Real-time water pressure monitoring to ensure you know how to use water
It is thoughtfully equipped with a built-in water pressure gauge to monitor the water pressure in your home in real time. When there are abnormal fluctuations in water pressure, family members can detect it in time and take effective measures. Generally, household water pressure needs to be maintained within a safe range of 0.1MPA - 1MPA. With OSWNKW-05, you can keep track of water pressure at any time to ensure safe water use.
5. Excellent material, quality choice
The 40-micron filter is made of selected 304L SUS stainless steel, which is tough, durable and has excellent corrosion resistance; the main body head is made of high-quality brass, which is sturdy and reliable. The heavy-duty food-grade transparent shell made in Germany is not only bisphenol A-free, but also has undergone 150,000 cycles of water hammer testing and a pressure test of up to 1,000 pounds per square inch. It has excellent explosion-proof performance and ensures the safety of your home water. The lifespan is more than several years.
6. Flexible installation, worry-free adaptation
The OSWNKW-05 pre-filter comes with a 1/2-inch and 3/4-inch male MNPT thread to fit any pipe. Whether your home has copper, PEX or CVC water pipes, you only need to purchase the corresponding adapter separately according to the actual specifications (the threaded adapter is not included in the package, but it is convenient to purchase) to easily complete the installation. Moreover, its advanced design ensures efficient filtration without affecting the existing water pressure level.
