That’s a fantastic question. Plenty of air purifiers air cleaners have activated carbon filters to help remove chemicals, odors, smoke, etc, and often it’s difficult to tell if it’s still working or otherwise not or exactly when you need to modify them. The manufacturers usually offer a suggested time period for changing filters, however suggest that how much time an activated carbon filter lasts really depends on the quantity of pollutants in the area, which is actually a little confusing.
A great guideline is always to change out all filters, charcoal powder once annually, particularly if you’re really understanding of indoor air pollution. If you’re extremely sensitive, don’t take a chance-improve your filters any moment symptoms even start to reappear.
Throughout us that may struggle to determine if we’re really sensitive or not, but still want a better notion of just how long our activated carbon/charcoal filters last and really when you ought to change them, there is a way to ‘test’ it-by how good it really is still removing odors and smells.
Military grade carbon in gas masks, and then in good carbon/charcoal air purifier filters work by absorbing or attracting airborne chemical residues in the air. And also since odors and smells are available from airborne chemical molecules and residues, if the activated carbon/charcoal filter within your air purifier continues to be working well, it will be able to mostly or completely remove an odor or smell in a case of minutes, right?
So, one way to ‘test’ your activated carbon/charcoal air filter is to place your air purifier either in the kitchen after you’ve finished cooking, making coffee, or spray just a little air freshener or cologne to the air around you, then turn air purifier on high for fifteen minutes or so. If the smell goes away completely completely or possibly is very noticeably reduced, the activated carbon/charcoal filter is most likely still doing its job trapping the airborne chemical molecules in charge of the smell.
It is possible to test the filter again later and in case it takes longer to eliminate the odors, that tells you that the carbon is ‘filling’ up as well as the air is needing to circulate from the air purifier a few more times to iiaqqj clean. True military grade carbon or charcoal filters (as with Austin Air purifiers) can do a more satisfactory job and stay longer, but once you start to notice that odors aren’t disappearing like they employed to, that carbon filter is probably ‘full’ and has to be changed to successfully and your family continue to be breathing clean air.
It is very important, however, if you’re utilizing an air cleaner for severe health issues, chemical sensitivities, or in a commercial application where hazardous airborne chemicals are present, to replace the carbon filters or at best install fresh bulk carbon on schedule or perhaps a little before to make sure compared to air cleaner isn’t circulating more pollutants than normal as the carbon filter is saturated and just blowing polluted air with the unit.
In addition there are various electronic and saturation / color change type chemical and VOC detectors and for any industrial applications where dangerous vapors or gases exist, we highly recommend using those that have your air cleaner to let you know if the filter has stopped removing the pollutants, or maybe air cleaner isn’t sufficiently removing them.
