Air purifiers are a great way to reduce the amount of allergens in your home. HEPA filters are especially effective in trapping contaminants like pollen, pet dander, dust mites, and tobacco smoke. These filters work by forcing air through a fine mesh that captures the particles, preventing them from floating and being inhaled. Whole-house HEPA filters must be installed by a professional HVAC company to ensure that air passes through and not around the filter.
Air purifiers equipped with HEPA filters can also help reduce pet dander, which is a common cause of allergies. The downside of air purifiers is that they can be noisy, consume energy, and require frequent filter replacements. To get the most out of your air purifier, make sure it is running all day in the room you spend the most time in. Whole-house air filtration units can also bring fresh air from outside and filter it before distributing it throughout the house.
HEPA filters are especially effective at reducing indoor pollen levels due to their ability to capture larger particles. To determine the air exchanges, divide the volume of air in the room by the cfm of the machine. The best air purifiers for allergies will use a combination of technologies to trap, reduce, and destroy airborne allergens.
