Do Air Filters Help Reduce Allergy Symptoms?

The Environmental Protection Agency (EPA) has said that HEPA filters can remove up to 99.97% of dust, pollen, and any airborne particulate matter with a size of 0.3 microns. That means they could help get rid of airborne pet dander. For more information, see the EPA guide to indoor air quality in your home. Using a HEPA filter in your home can remove most airborne particles that could worsen allergies.\But airborne particles aren't the only ones in your home.

There's so much more in your rugs, bedding, and curtains, and rest on countertops and tables. That's why it's important to keep these areas clean. It is also important, when 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.\If you suffer from allergies, you're probably looking for simple ways to reduce those annoying symptoms.

While we know that air purifiers can reduce the amount of pollution in the air, can they help reduce allergy symptoms? Some studies suggest that yes. However, there is more than one way to keep the air in the house clean. Learn how to alleviate allergy symptoms with the help of an air purifier and other ways to improve indoor air quality.\While more research is needed, some studies have shown that placing an air filter in the home can reduce indoor air pollution and alleviate allergy symptoms to some extent. However, the type of air purifier you use is important, as some air purifiers have been shown to aggravate allergies rather than alleviate them.

Ionic electrostatic room cleaners are not recommended for allergy sufferers, as they produce irritating ozone from the ions they release. Cheap fiberglass oven filters can also be harmful, especially if you forget to change the filter frequently. Also, be wary of air purifiers that claim to relieve allergy.\There is no scientific evidence that air purifiers that use UV rays, UV light, a light that kills bacteria, is useful for reducing allergies, although it is sometimes marketed as such. Air purifiers are particularly useful for people with animal and pet allergies.

According to the EPA, animal dander and cat saliva are some of the most common household irritants in the air. You can reduce the amount of pet dander in the air by placing an air purifier equipped with a HEPA filter somewhere in your space. They are also effective against dust, pollen, and other airborne contaminants larger than 0.3 µm. If you're only going to use it in one place, choose an air purifier with a clean air supply rate (CADR) that matches the intended room size.

If your home uses a central heating, ventilation, and air conditioning (HVAC) system, you can help the filtration system work throughout the house by installing a better air filter.\Permanent and disposable air filters are available. Allergens are substances that can cause symptoms in people with allergies, asthma, or respiratory conditions. According to the American Asthma and Allergy Foundation, 8 out of 10 people in the United States are exposed to dust mites and 6 out of 10 are exposed to dog or cat dander. One study cited several reports that HEPA air purifiers can benefit people with various allergies by reducing the concentration of indoor allergens, including pollen, house dust mite (HDM) allergens, and dog dander.

Research shows that mold can be especially harmful to people with asthma and other lung conditions, especially children.\Mold is a fungal growth that forms and spreads on various types of damp surfaces. Its presence indicates a problem with excess moisture. The EPA states that portable HEPA air purifiers have been shown to benefit allergy and asthma symptoms, as well as cardiovascular health. However, the amount of the benefit may be small, and the benefits may not be due solely to air filters.\If you have any underlying health problems such as asthma and allergies; talk to your doctor about ways you can improve indoor air quality to control symptoms.

Never stop taking any medication without first talking to your doctor. You can also look for air purifiers and filters that are certified as suitable devices for asthma and allergies by the American Asthma and Allergy Foundation. An allergist may also have specific recommendations tailored to your needs.\To work effectively; air purifiers need to remove extremely small particles suspended in the air; between 0.1 and 1 um. Particle filters are recommended for most allergy triggers; but if you're concerned about gaseous contaminants; using an activated carbon filter in your Blueair purifier helps remove airborne chemicals and gases.

This makes air purifiers useful during short-lived smoke from indoor garden fires; but they are not fully effective in protecting against the adverse health effects of tobacco smoke; whether primary or secondary. To filter gases; you should choose a portable air filter with an activated carbon filter or other filter designed to remove gases.\Many air purifiers contain several filters - one for particulate matter; one for gases; and even more so for gases; chemicals; or odors - so consider starting your search for an air purifier by clarifying what exactly you want it to do in your home. The problem is complicated by the fact that; in addition to being carried through the air; particles can become embedded in furniture; bedding; and carpets; as well as accumulate on hard surfaces such as walls and ceilings - so be sure to select the right Blueair air purifier for your room size to optimize performance and reduce pollen allergy triggers in your home. Whole house air purification systems exist; but they are connected to a home's heating; ventilation; and air conditioning (HVAC) system or facility - a HEPA filter is a type of mechanical air filter; it works by forcing air through a fine mesh that traps harmful particles such as pollen; pet dander; dust mites; and tobacco smoke.
