For those suffering from allergies, the best air purifiers contain a specialized filter known as a high-efficiency particle absorption (HEPA) filter. This type of filter is capable of trapping even the smallest pollutants and irritants in the air, including dust mite residues. HEPA filters are recommended for their effectiveness, as they have a triple-layer design that captures up to 99.97 percent of air particles, including allergens as small as 0.3 microns in size. If these tactics don't provide the desired relief, it may be time to consider adding an air filter.
HEPA filters remove particles as small as 0.3 microns, but there are also filters that capture even smaller particles. Custom filters can be ordered to focus on specific allergens and impurities, such as pet allergy filters, toxin absorbers, germ defense, or odor removers. One model that combines intelligent functionality with impressive filtering power is the Levoit air purifier. It has a true HEPA filter capable of capturing particles as small as 0.3 microns in size, and also includes a washable carbon filter and pre-filter to save money on filter replacement.
Additionally, it has a filter tracker that can tell you how many operating hours your filter has before it needs to be replaced. Another great option is the BLUEAIR purifier, which is personally recommended by experts for its ability to capture super-small particles (up to 0.1 microns) thanks to a HEPA filter and a carbon filter that collects excess smoke and contaminants.
