Clean indoor air is essential for allergy sufferers, as indoors is one of the few respites available in allergy seasons. If you're looking for an economical air purifier to help handle pollen and other common allergens, keep reading to see the best air purifiers under $100 so you can breathe healthier air quickly.
The main consideration is how well the unit captures or kills particles and microbes, so you also want to consider these filtration factors when searching for an effective air purifier:
- True HEPA Filtration: Often known as the gold standard when it comes to removing tiny airborne allergens, a HEPA air filter captures particles down to 0.3 microns with 99.97 percent efficiency. This includes pollen, dust, mold, and more. Learn more about what a HEPA filter is and how it works.
- High Heat: This is an effective alternative to HEPA filtration. Air purifiers that use heat to kill or disintegrate particles effectively sterilize the air, and are very quiet when operating.
- UV-C Light: Sometimes incorporated along with a HEPA filter, UV-C light kills airborne microbes too small for HEPA filters to capture, such as viruses.
