Is it really safe to filter water with a water purifier? Pure filter impurities are pre-filter, a set of water purifier can filter out harmful substances in the water, and retain the minerals needed by the human body.Generally speaking, the water purifier can filter out the following things:First, impurities such as rust and sediment;Two, remove calcium and magnesium ions in water, soften water;Third, remove residual chlorine, heavy metals, bacteria and various organic and chemical substances in the water.

Selection of air filters for central air conditioning Under normal circumstances,At the last level, the air filter of the central air conditioner determines the degree of air purification,The upstream filters at all levels only play a protective role,It protects the lower wind end filter to extend its service life,Or protect the air conditioning system to ensure it works properly.Air conditioning design,The efficiency of the final central air-conditioning air filter should be first determined according to the user's cleaning requirements,Then,Select the filter that plays a protective role,If this filter is also protected,Then add a filter on its upper end.The filters that play a protective role are collectively referred to as 'pre-filters '.The efficiency of central air-conditioning air filters at all levels should be properly matched.If the efficiency specification of the adjacent two-stage filter is too different,Then the previous level does not play the role of the post-protection level;If the differ
Is it reasonable for multi-media filters, self-cleaning filters, ultra-filtration, reverse osmosis, and mixing beds to be equipped in water treatment? Multi-media filter ultra-filtration reverse osmosis is only a process for producing pure water,If you use all this, it's not reasonable,The water you produce is estimated to reach 18 m,You can clean the circuit board directly---Multi-media filter,And the self-cleaning filter can be used in the pretreatment of reverse osmosis in the ultrasonic self-cleaning filter of Qinhuangdao century source,The added ultrasonic function has sterilization,The function of cleaning,Accuracy up to 2 microns.With the production of super-wave ultraviolet sterilizer,Super wave to remove wall dirt,Ensure that UV penetration is not affected,The sterilizer is thorough.
