How often do air purifiers change?
Air purifier inside the first layer of the common filter, which is shaped like a large air conditioning mesh filter, it can filter in advance, such as hair, such as pet hair bigger particle pollution. However, it will be used for a long period of time to gather a certain amount of dust, which can affect the intake and effect of air purification, so it needs to be cleaned in time. Pre filter is clean up 1 to 2 times a month, can remove the strainer when cleaning, use vacuum cleaners or cloth dust removal, such as the manufacturer to indicate the mesh can be washed, after rinse clean with water, dry or dry with hair dryer and then into the air purifier.
Basically see you use what kind of purifier, if it is physical adsorption, suggest you change of some more often, because organic pollutants within the purifier on the screen of accumulation, if the class of the purifier is a chemical decomposition, don't have that, because of the organic pollutants in carbon and hydrogen could be decomposed to produce water and carbon dioxide in the air. The latter is better than the latter, and I buy the UCHEER friendly, but not because of the lazy, but the idea that decomposing the formaldehyde is better than just the purifying effect of the adsorption
Your air purifier doesn't have a light. If you want to change the filter, you should look at your air environment for four to five months.
It depends on the environmental conditions and the frequency of use, generally on the air purifier has replaced screen prompt lamp, lamp to replace is ok according to clew, if pollution is severe suggest changing a march, but different mesh quality with long time is different also, generally good air purifier filter can use 6 months or so, a lot of air purifier is not once and for all appliances, personally, if you are lazy, like me, then I recommend you use UCHEER friendly air purifier, its catalytic filter itself has no loss in the process of decomposition of formaldehyde, can achieve more than 10 years of continuous function, and do not need to change, though not once and for all, but also save a lot of trouble.
