Carbon / Charcoal Air Filters Activated: How long do they really last?
That is a big question. Many air purifiers / air cleaners have activated carbon filters to help eliminate pollutants, odors, smoke, and so on, and sometimes it’s hard to tell whether it still works, or not, or exactly when you need to fix it. Usually the manufacturers give a suggested timeframe to change the filters, but then state that how long an activated carbon filter lasts is really dependent on the amount of pollutants in the area, which is a bit confusing.Learn more by visiting Pacific Coast Carbon LLC
A good thumb rule is to change all filters, HEPA and activated carbon / charcoal filters once a year, especially if you are really sensitive to air pollution indoors. Do not take a chance-change of your filters once symptoms begin to reappear if you are extremely sensitive.
For the rest of us who may not be able to say whether or not we are very prone, but who want a better understanding of how long our activated carbon/charcoal filters last and even when to adjust them, there’s a way to ‘check’ it-by how well it who absorbs odors and smells.
Military carbon in gas masks and good carbon / charcoal air purifier filters are used to absorb or attract airborne chemical residues in the air. And because odors and smells often come from airborne chemical compounds and contaminants, if an activated carbon / charcoal filter still works well in your air purifier, it should be able to eliminate the odor or smell mostly or completely in a matter of minutes, right?
So, one way to ‘check’ your activated carbon/charcoal air filter is to either place your air purifier in the kitchen after you’ve done cooking, coffee making, or spray a little air freshener or cologne into the air around you, then turn the air purifier on high for about 15 minutes. The activated carbon / charcoal filter is probably still doing its job trapping the airborne chemical molecules which are responsible for the smell if the smell goes away completely or is very noticeably reduced.
You should check the filter again later and if it takes longer to get rid of the odors, that can warn you that the carbon is ‘filling up’ and that the air needs to circulate a few more times to clear up the air purifier.
