Do air purifiers really work?
Yes they do. A good HEPA air purifier would be able to remove airborne particles, smoke, and odors. The keyword you are looking for is HEPA. An air purifier with a True HEPA filter has a 99.97% efficiency in trapping particles as small as 0.3 microns. This includes hair, dust mites, pet dander, mold, mildew, pollen, bacteria, and virus. Brands like Blueair can further target allergens down to 0.1 microns with its HEPASilent. IQAir takes the cake with its HyperHEPA filter. It can capture particles 100 times smaller than what a standard HEPA filter would. For tobacco smoke, cooking smell, radon, VOCs, ammonia, or CO, a good carbon filter is needed instead. Look for keywords like activated charcoal, catalytic carbon, or zeolite.
There are many different types of air purifiers in the market that is simply ineffective. Out of the bunch, Ionizer and Ozone generator should never be in your consideration list. Also, choose the RIGHT air purifier according to your room size and needs. You can refer to the air purifier’s CADR or recommended room size to make your judgment.
Do Air Purifiers Improve Health
An air purifier can improve our health particularly to our lungs. By filtering out all the harmful particles, your lungs will only breathe in and exhale clean air. Also, fewer allergens will be able to infiltrate to our body via skin absorption and mouth. In short-run, you will experience less sneezing, headache, cough, and skin rash. In long-run, you are reducing the risk of many respiratory problems including asthma.
Air purifier exists for more than half of century and is still selling like hotcakes today because it works. However, it would not be able to address all the pollutants in a room. Regular vacuuming and mopping is a must as dust, allergens that are not airborne will fall. Keep your room well-ventilated by opening more windows or door. Ensure your furnace or HVAC system is properly maintained. Lastly, avoid burning scented candle, fireplace or smoking indoor.
Frequently Asked Questions FAQ
Do Air Purifiers Remove Smoke ?
Yes but only if the air purifier is equipped with an activated carbon filter or similar. Through chemical adsorption, the carbon filter will only remove smoke impurities. This covers cigarette smell, chemical fumes like VOCs, CO, cooking odors and more. Gaseous pollutants that are not attracted to the carbon will flow right through.

Do Air Purifiers Work for Mold
A genuine HEPA air purifier can remove airborne mold spores. If the air purifier comes attached with a carbon filter, it will get rid of the musty odors altogether. However, if the mold is already stuck to the wall or on the ground, there is nothing an air purifier can do. It also can't prevent mold and other microbes from growth. You will need a dehumidifier to do that.
