Air purifiers trap dust, pollen and other contaminants that float in the air we breathe, so they can be effective in eliminating the source of allergies. However, it is important to note that they should not replace prescription medications. Only ionizing air purifiers can exacerbate allergies (more on them later). Studies have shown that air purifiers can help people with common allergies by trapping pollen and other irritants inside their filters, but there is still little consensus on the subject.
Using a HEPA filter in your home can remove most of the particles in the air that could worsen allergies. But airborne particles aren't the only ones in your home. There's much more to their carpets, bedding, and curtains, and they rest on countertops and tables. That's why it's important to keep these areas clean.
It is also important, whenever possible, to eliminate the source of allergens and irritants. For example, the only effective way to keep tobacco smoke out of your home is to not smoke. An air purifier can work in conjunction with a high-efficiency particulate air (HEPA) filter, the latter of which is best known for trapping airborne allergens. Like allergens, indoor mold particles can become especially dangerous for people with asthma and other lung conditions.
Air purifiers can work to a certain extent, but filtration is much more effective at removing mold from the air. Not only can your home be a source of airborne allergens and mold, but it can also be a source of indoor toxins from cleaning products, personal care products and more. Research shows that filtering air can help remove harmful particles from indoor spaces, especially allergens, smoke and mold. Never buy “air purifiers” ozone generators.
According to the EPA and doctors, ozone is a respiratory irritant and, in fact, can worsen allergy or asthma symptoms. The right air purifier can also remove irritants such as smoke, odors and VOCs (volatile organic compounds). These are not allergens, but they can make it difficult to breathe. So if these are the things that bother you, then an air purifier can really help you with your allergies.
A professional HVAC company must install a HEPA filter for the whole house and be properly sized for its air treatment unit, in order to protect the life of the equipment and ensure that air passes through the HEPA filter and not around it. If you have a central air conditioning system, consult an accredited contractor about replacing the manufacturer's filter with an approved furnace filter (the right size for your unit and the size of your air ducts) with a minimum efficiency rating (MERV) of 11 or 12, and then configure the fan so that it works continuously. The type of air filter you use is also important, as some work by capturing and filtering larger allergen particles, such as dust, while others, such as UV purifiers, work better at killing mold and bacteria. In fact, the Environmental Protection Agency (EPA) warns that the functionality of air purifiers is limited in terms of filtering gases and that filters must be replaced frequently to work optimally, usually approximately every three months.
Some versions are made with filters to trap particles as air passes through them, while others can neutralize other particles in the air without first filtering them. PhoneSoap states that this air filter can also reduce allergens, such as pet dander, and help purify polluted, smoke-filled air more than traditional filters, which can build up contaminants if not changed frequently enough. .
