Pet odors cause can cause many allergy, asthma, and respiratory issues. Most pet owners purchase a pet air purifier to remove these pollutants from the air.

Pet air cleaners are definitely worth buying, but for an air purifier to effectively have a HEPA filter, an activated carbon filter with at least 4-5 pounds of the best quality granular carbon, and a strong output of at least 200 CFM. A true HEPA Filter removes over 99% of hazardous particles down to 0.3 microns from the air.

The carbon filter has to have a high quality activated carbon or charcoal to effectively remove pet odors, which are essentially VOC's, so look for carbon that can remove VOC's. The more carbon the filter contains the longer the filter will last. And the output is very important. If the unit can't move at least 200 cubic feet per minute of air, it will not clean the air.

Higher CFM units such as a 400 CFM, which means they can cycle all of the air in an average room in about 2 minutes, which is sufficient to prevent you from breathing the animal odors. Most cheap air purifiers don't have all three of these features and that is why they don't work very well.

So, if you buy a pet air cleaner with a quality HEPA filter, a substantial activated carbon filter and strong output, the unit will do the job, but you must replace the filters on time for best results.
