Coverage Area – The first thing to note is the coverage area of an air purifier you are about to buy. First, you should know the area of your room and then you should buy an air purifier that is effective for the entire room. Otherwise, covering half the area will be ineffective. There are certain purifiers available that are suitable for the entire home as well.
Filter Type – There are different filters available in different air purifiers. Some of the filters are HEPA filters, activated carbon filters, antibacterial filters, charged media filters, electrostatic precipitator, pre-filter, heat filters and much more. The more filters you have in your air purifier, the more efficient it is. HEPA is perfect for removing allergens and particulate matter. Carbon activated filters absorb odors and gases as well as neutralize certain chemicals. Antibacterial filters are a must. PCO breaks down chemicals and make them harmless. Pre-filters eliminate dust and large particles like hair. Heat filters kill bacteria, viruses, mold, and mites. Check out the air purifier reviews before buying any.
Air Exchange Rate – This is a technical factor that most of the buyers do not pay attention to.
