HEPA Filters & Vacuum Cleaners 
(High Efficiency Particulate Air)


These special filters are best for people with allergies because they capture hair, dander, pollen, dust, and other allergens. They are effective at picking up particles as small as .03 microns. HEPA filters are available in air purifiers and vacuum cleaners. Allergens, pet hair, and dirt embed deeper into carpets than traditional vacuum cleaners can reach, but vacuum cleaners with HEPA filters capture 99.9% of allergens. I highly recommend that vacuums without the HEPA feature be replaced for people with allergies or asthma. When vacuuming, make sure to clean all carpets, throw rugs, uphostered furniture, curtains, throw pillows, and books because they harbor dust mites and other allergens. I also recommend that HEPA air purifiers be run in the bedroom at night to help provide a more peaceful sleeping environment free of allergens.

When purchasing a HEPA air purifier or vacuum cleaner, be sure to investigate replacement filter costs. Replacement filter costs can be expensive, so look for ones without disposable filters. Some purifiers have the feature of filters that never need to be replaced, but only washed two to four times a year. Purchasing purifiers with this feature can reduce the expense and increase the convenience of owning a HEPA air purifier. HEPA filters with old or dirty filters serve no purpose, so make sure you clean or replace filters on a routine schedule!
