If you are an allergy sufferer, you may have heard that an air filter can help with allergy symptoms. But, which air filter is the best one?
Which Air Filter Is Best for Home Allergies?
There are many different allergens, including dust mites, pollen, molds and many others. Particles of different allergens also range in size. As such, it’s important that an air filter is capable of capturing a range of different sized particles.
With this in mind, the best air filter for allergies is the HEPA filter (which stands for high-efficiency particulate air), one of the most powerful air filters available on the market today. HEPA filters are capable of trapping 99.97% of particles in the air that are as small as 0.3 microns. That means that HEPA filters are capable of capturing very small particles, including dust, pollen, dander and even tobacco smoke.
Just how much can HEPA filters help? HEPA filters can actually remove the majority of airborne particles that make your allergy symptoms worse. That’s why many medical experts will advise that allergy sufferers invest in HEPA filters as part of their treatment plan. One important thing to note, however, is that there are many air filters on the market that claim to be HEPA filters, but actually aren’t as effective. In order to be considered a real HEPA filter, it has to be able to trap at least 99.97% of all particles down to 0.3 microns in size.
How HEPA Filters Work
HEPA filters work by effectively trapping various airborne allergens inside them. Essentially, the air filter forces air through the fine mesh filter that traps various allergens like pollen, pet dander and so on. Keep in mind, however, that it’s important that you change the air filter as often as recommended by the manufacturer for best results.
HEPA filters can be purchased for your HVAC system, your vacuum cleaner and even your air purifier. HEPA equipped vacuum cleaners prevent various allergens like dust and pet dander from being dispersed back into the room as you vacuum.
HEPA filters are highly effective at trapping airborne allergens. However, as you likely know, allergens are also present in rugs, bedding, drapes and so on. Therefore, it’s important to ensure that these are also cleaned regularly to remove any allergens.
