What type of filter is best for allergies?

But the best air purifiers for allergies contain a type of specialized filter called a high-efficiency particle absorption (HEPA) filter, which is capable of trapping even the smallest pollutants and irritants in the air. Even small dust mite residues are no longer a problem for these machines. You should also pay attention to the type of filter that the purifier uses. HEPA (High Efficiency Particle Absorption) filters are recommended for their effectiveness, and their triple-layer design captures up to 99.97 percent of air particles.

These filters can capture allergens as small as 0.3 microns in size, making them even more important for those seeking to alleviate their allergy. Dass says that purifiers with HEPA filters have been the most studied and the only ones that have been shown to filter particles as small as 0.3 micrograms. Look for an air filter in second place If you've tried these tactics and can't find the right relief, it might be time to consider adding an air filter. HEPA filters remove particles as small as 0.3 microns, but you can also find filters that capture even smaller particles.

You can also order custom filters that focus on specific allergens and impurities, such as pet allergy filters, toxin absorbers, germ defense, or odor removers. So we looked for air purifiers with HEPA filters that would use activated carbon or similar purification ingredients to help filter out allergens such as pet hair, pet dander, pollen and smoke. This Levoit model combines intelligent functionality with impressive filtering power, thanks to the connectivity of its smartphone and a true HEPA filter capable of capturing particles as small as 0.3 microns in size. The washable carbon filter and pre-filter make this unit save a lot of money on filter replacement.

It also has a filter tracker that can tell you how many operating hours your filter has before it needs to be replaced. BLUEAIR purifiers are personally recommended by Fitzgerald, who points out that they can capture super-small particles (up to 0.1 microns) thanks to a HEPA filter and a carbon filter that collects excess smoke and contaminants.
