An air purifier can mean cleaner air for those with allergies or breathing disorders of any sort, and just for those who are concerned about their surrounding environment. These purifiers can be necessary if you live in an area near a production facility that may have a smoke stack, or if your home tends to trap and hold dust, pet hair, and the like. When you're ready to shop for an air purifier, note a few tips for choosing the right filter or type of purifier for your home so you know you get something you'll love for many years to come.


Pre-filters work like furnace filters; they trap very large particles such as pet hair and dander, human hair and dead skin cells, and other such common irritants in the air. They don't work as well on microscopic contaminants but can offer a cleaner environment, especially if you have pets or just want to clean the air a slight bit for easier breathing and better health. They're also the most affordable choice for most and easiest to maintain, as you usually just replace the filter when needed as you do with your home furnace.

Carbon filters

Carbon filters will filter out things like cigarette smoke, mildew, as well as volatile organic compounds; these are irritants from paints, air fresheners, and other such materials. They also filter gasses and most odors in the air. These carbon filters are also typically easy to change and carbon filter air purifiers are also relatively affordable for most persons, although they may still be slightly more expensive than pre-filters. Note, however, that they don't typically filter out very fine or microscopic irritants.

HEPA filter

A HEPA filter is better at killing microscopic irritants than other filters, including mold spores and pollen. They are usually recommended for those who have severe breathing disorders or allergies, and those who are concerned about maximum cleanliness, as HEPA filters are used in hospital environments and doctor's offices. The HEPA filter itself is much more narrow than you would find in other filters and the fibers of this filter twist and weave to trap even the smallest irritant. However, this can be one of the most expensive of all types of air filters and the filters themselves can be costly. You may not need a HEPA filter until you've been recommended to have such a filter by your doctor, so you might consider it carefully before purchasing.
