That’s a great question. Plenty of air purifiers air cleaners have activated carbon filters to aid remove chemicals, odors, smoke, etc, and often it’s difficult to determine if it’s still working or otherwise or exactly when you want to change them. The makers usually provide a suggested period of time for changing the filters, but then suggest that just how long an activated carbon filter lasts really depends on the level of pollutants in the area, that is a little confusing.
A great principle is to change out all filters, charcoal teeth whitening once each year, particularly when you’re really responsive to indoor air pollution. If you’re extremely sensitive, don’t take a risk-alter your filters any time symptoms even commence to reappear.
Throughout us that may struggle to know if we’re really sensitive or otherwise not, yet still need a better idea of how long our activated carbon/charcoal filters last and incredibly when you ought to change them, there is a method to ‘test’ it-by how well it is still removing odors and smells.
Military grade carbon in gas masks, as well as in good carbon/charcoal air cleaner filters work by absorbing or attracting airborne chemical residues within the air. And since odors and smells are available from airborne chemical molecules and residues, if an activated carbon/charcoal filter inside your air purifier continues to be working well, it should be able to mostly or completely remove an odor or smell in a question of minutes, right?
So, one way to ‘test’ your activated carbon/charcoal air filter is to put your air cleaner either in the kitchen after you’ve finished cooking, making coffee, or spray just a little air freshener or cologne in to the air around you, then turn air purifier on high for 15 minutes or so. When the smell goes away completely completely or is very noticeably reduced, the activated carbon/charcoal filter may well be still doing its job trapping the airborne chemical molecules accountable for the smell.
You can test the filter again later and if it takes longer to eliminate the odors, that tells you that this carbon is ‘filling’ up and the air is being forced to circulate through the air purifier a few more times to iiaqqj clean. True military grade carbon or charcoal filters (like Austin Electronic home air cleaners) is going to do a better job and keep going longer, but once you start to notice that odors aren’t going away like they employed to, that carbon filter is probably ‘full’ and has to be changed to make sure you and your loved ones are still breathing clean air.
It is very important, however, if you’re utilizing an air cleaner for severe medical issues, chemical sensitivities, or perhaps in an industrial application where hazardous airborne chemicals can be found, to switch the carbon filters or at least install fresh bulk carbon on schedule or even a little before to make sure compared to the air cleaner isn’t circulating more pollutants than usual since the carbon filter is saturated and just blowing polluted air from 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 strongly recommend using those that have your air cleaner to inform you if the filter has stopped taking out the pollutants, or if the air cleaner isn’t sufficiently removing them.
