The Role of Different Water Filters

Before you choose to install a water filter, you need to understand the function of different types of water purifiers. They are an important criterion for you to choose a water purifier.
The pre-water filter can only filter out large particles that are generally visible to the naked eye, such as sediment, rust, bloodworms and other substances; the product structure is small and light, with a clear filtration accuracy (5, 50, 100), and a large flow rate. , It can discharge sewage, has a long service life of the filter element, and has a low failure rate. It can protect downstream equipment, such as high-end faucets from clogging, and less sediment in the water heater; it has limited functions and can only filter impurities that are greater than the set filtration accuracy, similar to yellow water. Black water, peculiar smell water, water alkali, scale, and heavy metals cannot be removed, because the filtering principle of sieving has a slight impact on the water pressure of the pipeline tap water.
The ultrafiltration water filter uses the hollow fiber membrane internal pressure or external pressure filtration technology, and the filtration pore size of the membrane reaches the nanometer level, so the filtration effect is much better than that of the pre-filter and PP cotton. Smaller bacteria, viruses, carbon black and other water-insoluble particulate matter can be intercepted and filtered; but it has no ability to remove organic pollution, chemical pollution, odor, pigment and other substances dissolved in water, resulting in poor taste after treatment of tap water .
The filtration accuracy of the reverse osmosis water filter reaches 0.5-10nm nanometers, which can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in the water; the filtration is more thorough, and the water produced by reverse osmosis and nanofiltration is clean, safe and tasteful Excellent; it can completely remove water alkali and scale, and the water purification effect is very obvious. If the water pollution is serious or the water quality is not clear, it is recommended to use this type of water purifier.
