You may not know it but indoor pollution is now a serious problem. The air in buildings that lack proper ventilation may be up to five times more polluted than the air outside.
The reason for this is that modern buildings are designed to be energy efficient, trapping warm or cool air indoors. At the same time, pollutants are also trapped inside.
Because the average American spends most of his time indoors, it is important to keep the air in the home or office free of pollutants. The best air purifiers are useful in removing allergens and other airborne pollutants so people can breathe pure, fresh air.
Common Indoor Pollutants
Molds, dust and dust mites are common air pollutants in the average home. Pollen is also a major airborne pollutant, as well as viruses and bacteria. It you have pets, you can be sure there is dander all over the house.
Volatile Organic Compounds (VOCs) such as fragrances, cleaning agents, solvents and pesticides in the air can also cause allergic reactions and other health problems.
What To Look For In An Air Purifier
The best air purifiers are able to remove dust, smoke, dander, odors and pollen from your home or office. There are some considerations to think about if you want to ensure that your air purifier is doing the best job.
• The air purifier must have a high CADR or Clean Air Delivery Rate, a measure of how many cubic feet of clean air the unit can deliver per minute. Choose an air cleaner with a CADR rating of at least 50 for every 80 square feet of space in the room.
• Air purifiers with HEPA filters are best for removing airborne allergens and other pollutants. HEPA filters can remove at least 99.97% of pollutants measuring as little as 0.3 microns.
• Some air purifiers have electrostatic ionizers that charge the airborne particles in the air and trap them, or cause them to be heavy enough to fall to the floor. The drawback with this kind of air cleaner is that it produces small amounts of ozone that can cause health problems.
• Many of the best air purifiers are equipped with activated carbon filters to remove odors, tobacco smoke, chemical toxins and gases. They also have the ability to trap VOCs.
• Ask to have the air purifier plugged in and tested. Listen to the level of noise that it makes. Some air purifiers are quiet while others are noisy enough to be annoying.
