Using a HEPA filter in your home can remove the majority of airborne particles that might be irritating or aggravate allergies. But the particles suspended in air are not the only ones in your home. There are far more in your rugs, bedding, and draperies and resting on countertops and tabletops. For that reason, it's important to keep these areas clean. It's also important, when possible, to get rid of the source of allergens and irritants. For example, the only effective way to keep tobacco smoke out of your home is to not smoke.
Nevertheless, these filters can be part of an effective strategy to remove irritating particles from your home.
