That’s a fantastic question. Lots of air purifiers air cleaners have activated carbon filters to help remove chemicals, odors, smoke, etc, and often it’s hard to tell if it’s still working or otherwise or exactly when you need to modify them. The manufacturers usually provide a suggested time frame for changing filters, however claim that just how long an activated carbon filter lasts really depends on the amount of pollutants in the area, that is a little confusing.
A great rule of thumb is always to change out all filters, activated charcoal once annually, particularly when you’re really responsive to indoor air pollution. If you’re extremely sensitive, don’t take a risk-change your filters at any time symptoms even start to reappear.
Throughout us which could struggle to know if we’re really sensitive or not, yet still need a better idea of how long our activated carbon/charcoal filters last and incredibly when you should change them, there is a approach to ‘test’ it-by how well it is still removing odors and smells.
Military grade carbon in gas masks, and then in good carbon/charcoal air cleaner filters work by absorbing or attracting airborne chemical residues in the air. And also, since odors and smells come from airborne chemical molecules and residues, if the activated carbon/charcoal filter in your air cleaner continues to be working well, it must 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 place your air purifier either in your kitchen after you’ve finished cooking, making coffee, or spray a little air freshener or cologne into the air surrounding you, then turn air purifier on high for a quarter-hour approximately. In the event the smell goes away completely or possibly is very noticeably reduced, the activated carbon/charcoal filter is probably still doing its job trapping the airborne chemical molecules in charge of the smell.
You can test the filter again later and if it will take longer to get rid of the odors, that lets you know that this carbon is ‘filling’ up and also the air is having to circulate with the air cleaner a few more times to iiaqqj clean. True military grade carbon or charcoal filters (as with Austin Electronic home air cleaners) is going to do a better job and last longer, but once you start to notice that odors aren’t going away like they utilized to, that carbon filter is probably ‘full’ and must be changed to successfully and your family are still breathing clean air.
It is very important, however, if you’re using an air cleaner for severe health issues, chemical sensitivities, or in an industrial application where hazardous airborne chemicals are present, to change the carbon filters or at least install fresh bulk carbon on schedule or a little before to make certain compared to the air cleaner isn’t circulating more pollutants than usual since the carbon filter is saturated and just blowing polluted air through the unit.
There are also various electronic and saturation / color change type chemical and VOC detectors and for any industrial applications where dangerous vapors or gases exist, we strongly suggest using those that have your air cleaner to let you know when the filter has stopped eliminating the pollutants, or if the environment cleaner isn’t sufficiently removing them.
