Is tap water only filtered with PP cotton?

2023-08-17

Sure！ The tap water coming out of the water plant is originally qualified, and there is no problem in terms of safety, but it will be polluted by rust sludge after passing through various old pipes. The pp filter element just solves this problem. PP cotton is made of non-toxic and tasteless polypropylene particles, with a minimum filtration of 1 micron, which can effectively filter rust, sediment, insect eggs, algae and other large particles in water, and is usually used as a pre-physical filter. The water output has almost no attenuation. Raw water (tap water, ground water, etc.) flows from the outside of the PP cotton to the inside, and is filtered layer by layer. The closer to the inner layer of the filter element, the smaller the pore size, the higher the filtration accuracy. When the particulate impurities pass through the pores of the PP filter element, bridging will occur. Even particles smaller than the pores can be blocked, thus effectively removing various particulate impurities in the filtered liquid.

Is it better to use two cottons and one carbon for the first three stages of the reverse osmosis water purifier or one cotton and two carbons?

The effect of the two-layer PP cotton filter element is better, it can intercept large particles of impurities, such as suspended solids in water, sediment, rust, etc., and can prolong the service life of the water purifier.

The two filter elements are one of the more widely used water purifier filter elements, but their functions are different. The pp cotton filter element is used to remove larger particles in the water, while the activated carbon filter element is used to absorb chlorine and bacterial microorganisms in tap water and kill bacterial microorganisms.
