Activated Charcoal / Charcoal Air Filters: How Long Do They Really Last?

This is an excellent question. Many air purifiers / air filters have activated carbon filters to help remove chemicals, odors, smoke, etc., and sometimes it's hard to tell if it still works or not or when you need to change them. Manufacturers usually give a suggested time to change the filters, but then indicate how long an activated carbon filter really depends on the amount of pollutants in the area, which is a little confusing.

Replace all filters, HEPA filters and activated charcoal / charcoal once a year, especially if you are very sensitive to indoor air pollution. If you are extremely sensitive, do not take a risk – change your filters every time symptoms begin to reappear.

For the rest of us who can not know if we are really sensitive or not, but we still want to have a better idea of ​​the lifespan of our activated carbon / charcoal filters and know when to change them, there is a way to "test" them. – how odors and odors are always eliminated

Gas masks and charcoal / charcoal air purifier filters work by absorbing or attracting chemical residues into the air . And since smells and odors also come from molecules and airborne chemical residues, if an active charcoal / charcoal filter in your air purifier still works well, it should be able to eliminate an odor or smell in minutes,

So, one way to "test" your activated charcoal / charcoal filter is to put your air purifier in the kitchen after you finish cooking, making coffee or spraying some deodorant or cologne. around you, then turn the air purifier on high for 15 minutes or so. If the odor disappears completely or is very significantly reduced, the activated carbon / charcoal filter is probably still doing its job trapping the airborne chemical molecules responsible for the odor.

You can test the filter later and if it takes longer Get rid of odors that tell you that the carbon is filling up and that the air has to circulate in the air purifier a few times. more to become clean. True military-grade coal or coal filters (as in Austin Air purifiers) will do a better job and last longer, but once you start to notice that the odors do not go away like before, this carbon filter is probably full. must be changed to ensure that you and your family still breathe clean air.

However, it is very important to use an air filter for serious health problems, chemical sensitivities or in an industrial application where it is dangerous airborne chemicals are present, to replace the carbon filters or at least install loose bulk carbon on time or a little earlier to ensure that the air filter does not circulate more pollutants than normal because the carbon filter is saturated

There are also Various chemical and VOC type saturation / color change detectors and for any industrial application where hazardous vapors or gases are present, we strongly recommend to use Use your air filter to warn you when the filter has stopped. 39 remove the pollutants or if the air filter does not remove enough.
