That’s a fantastic question. A lot of air purifiers air cleaners have activated carbon filters to help remove chemicals, odors, smoke, etc, and sometimes it’s tough to tell if it’s still working or not or exactly when you need to change them. The manufacturers usually provide a suggested time frame for changing filters, however claim that how much time 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 to change out all filters, coconut shell charcoal powder once each year, especially if you’re really understanding of indoor air pollution. If you’re extremely sensitive, don’t take a risk-improve your filters at any time symptoms even start to reappear.
For the rest of us that may struggle to tell if we’re really sensitive or not, but still want a better idea of how long our activated carbon/charcoal filters last and extremely when you should change them, there exists a approach to ‘test’ it-by how well it really 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 in the air. And also, since odors and smells come from airborne chemical molecules and residues, if an activated carbon/charcoal filter inside your air cleaner 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 place your air cleaner either in the kitchen area after you’ve finished cooking, making coffee, or spray a bit air freshener or cologne to the air close to you, then turn the environment purifier on high for a quarter-hour roughly. 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 are able to test the filter again later and if it requires longer to eliminate the odors, that informs you that the carbon is ‘filling’ up and the air is needing to circulate with the air cleaner a few more times to iiaqqj clean. True military grade carbon or charcoal filters (as in Austin Air cleaners) is going to do a better job and stay longer, but once you begin to notice that odors aren’t going away like they utilized to, that carbon filter may well be ‘full’ and needs to be changed to make sure you and your family remain breathing clean air.
It is very important, however, if you’re employing an air cleaner for severe medical issues, chemical sensitivities, or perhaps in a commercial application where hazardous airborne chemicals are present, to replace the carbon filters or at least install fresh bulk carbon on schedule or even a little before to make certain compared to air cleaner isn’t circulating more pollutants than usual as the carbon filter is saturated and merely blowing polluted air through 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 are present, we strongly suggest using those with your air cleaner to inform you once the filter has stopped removing the pollutants, or maybe air cleaner isn’t sufficiently removing them.
