What to Look for in an Air Purifier

Given the fact that there are so many air purifier brands on the market, it is necessary for consumers to know that the product they are investing in actually cleans the air. This article provides the most important features that an air purifier must have in order to truly provide real results.

True HEPA Filter

The top air purifiers in the world utilize a HEPA filter. Developed in the 1930s, HEPA was originally created for the US Military during the Manhattan Project. True HEPA filtration is rated to capture 99.97% of all particles, microorganisms and allergy triggers from the air. As contaminants are pulled into the air purifier, the HEPA filter traps them within the fine borosilicate fibers, where they are unable to be released back into the air. Because of this advanced particle filtration, both allergy and asthma sufferers benefit greatly from the use of HEPA filtration.

Carbon Filter

Another essential component would be carbon filtration. Typically featured as a blend with either zeolite or potassium, carbon is able to remove hazardous chemical pollutants, noxious odors and volatile organic compounds from the air. As polluted air passes through the carbon filtration stage, these invisible gaseous molecules become embedded within the carbon granules. Therefore, carbon filters are a must in environments where chemicals are present.

Large Surface Pre-Filter

A pre-filter is designed to capture mid to large sized particulates as they are pulled into the air purifier unit. In doing so, both the HEPA and carbon filters are able to focus primarily on removing the finer pollutants from the air. Having a large size pre-filter helps extend the life of the other two filtration elements.

Additional air purifier features to look for would include: ozone-free operation, durability, an extended warranty, and filters designed for long term usage. Most importantly, it is best to avoid low priced department store air purifiers as they are usually ineffective at cleaning the air, and in some cases, produce dangerous levels of ozone when in operation.
