Activated Carbon/Charcoal Air Filters: How Long Do They Actually Last?

That is a good query. A lot of air purifiers/air cleaners have activated carbon filters to assist get rid of chemical compounds, odors, smoke, and so on, and at times it’s difficult to tell if it’s nonetheless functioning or not or specifically when you need to have to alter them. The suppliers typically give a recommended time frame for changing the filters, but then state that how lengthy an activated carbon filter lasts actually depends on the amount of pollutants in the area, which is a tiny confusing.

A very good rule of thumb is to transform out all filters, HEPA and activated carbon/charcoal filters when per year, specifically if you happen to be seriously sensitive to indoor air pollution. If you’re incredibly sensitive, do not take a likelihood-transform your filters any time symptoms even commence to reappear.

For the rest of us that might not be capable to tell if we’re genuinely sensitive or not, but still want a much better thought of how lengthy our activated carbon/charcoal filters final and seriously when to transform them, there is a way to ‘test’ it-by how effectively it is nevertheless removing odors and smells.

Military grade carbon in gas masks, and in fantastic carbon/charcoal air purifier filters function by absorbing or attracting airborne chemical residues in the air. And considering the fact that odors and smells also come from airborne chemical molecules and residues, if an activated carbon/charcoal filter in your air purifier is still working effectively, it ought to be able to mostly or completely remove an odor or smell in a matter of minutes, suitable?

So, 1 way to ‘test’ your activated carbon/charcoal air filter is to put your air purifier either in the kitchen following you have finished cooking, creating coffee, or spray a tiny air freshener or cologne into the air around you, then turn the air purifier on higher for 15 minutes or so. If the smell goes away completely or is quite noticeably reduced, the activated carbon/charcoal filter is probably nevertheless undertaking its job trapping the airborne chemical molecules accountable for the smell.

You can test the filter again later and if it requires longer to get rid of the odors, that tells you that the carbon is ‘filling’ up and the air is needing to circulate via the air purifier a couple of extra times to turn into clean. Accurate military grade carbon or charcoal filters (as in Austin Air purifiers) will do a improved job and last longer, but as soon as you commence to notice that odors aren’t going away like they made use of to, that carbon filter is likely ‘full’ and demands to be changed to make confident you and your loved ones are nevertheless breathing clean air.

It is incredibly crucial, nevertheless, if you’re utilizing an air cleaner for serious overall health troubles, chemical sensitivities, or in an industrial application where hazardous airborne chemical substances are present, to replace the carbon filters or at least set up fresh bulk carbon on schedule or a small ahead of to guarantee than the air cleaner isn’t circulating a lot more pollutants than normal simply because the carbon filter is saturated and just blowing polluted air through the unit.

There are also a variety of electronic and saturation / color alter kind chemical and VOC detectors and for any industrial applications where unsafe vapors or gases are present, we highly advise employing these with your air cleaner to let you know when the filter has stopped removing the pollutants, or if the air cleaner isn’t sufficiently removing them.

Hi, ‘m Rex Murphy, owner of Air Purifiers and I wrote this post to aid shed some light on how extended carbon air filters last and when it makes sense to replace them.
