The first step in treating indoor allergies is to prevent those allergens from entering the home. That’s why people with allergy respiratory diseases are commonly advised to use air filtration as part of their environmental management strategies.

Allergens are often nontoxic chemicals that might cause an unfavorable allergic reaction in some people. These small allergens and minuscule air pollutants can often and occasionally even severely aggravate allergy responses in those who already have allergens. Understanding the kind and location of environmental allergen sources is essential to avoid or lessen the symptoms of common allergies.

Scientific research has discovered that air filtration lowers the number of airborne contaminants in the air and may offer some comfort to those affected by allergies. That’s where a MERV filter comes in.

What Is MERV?

MERV is referred to as Minimum Efficiency Reporting Value.  When an air filter is considered efficient, it can effectively filter out particles of a particular size or range from the air that passes through it. An air filter’s MERV rating shows how effective it is at lowering the amount of 0.3 to 10 micron-sized airborne particles that flow through into the filter.

The effectiveness of appropriate MERV air filters for allergies is determined by how successfully they filter out particles of various sizes. The rating method is known as the Minimum Efficiency Reporting Value or MERV. The ratings vary from MERV 1 to MERV 20, with the greater number suggesting filters that can remove the tiniest particles, including various allergen species.

These filters work by pushing air through tiny mesh that collects airborne allergens and particles including dirt, animal dander, dust mites, cigarette smoke, and more before they can penetrate our bodies through breathing. The higher the MERV rating, the more particles it will filter out of the air you breathe.

Do MERV Filters Reduce Allergy Symptoms?

Air filters for allergens are designed to stop considerably smaller contaminants. For example, an air filter with an appropriate MERV filter rating can be used to eliminate the allergens brought on by pet dander. Most air purifiers collect particulates like dirt and pollen. Where the finest air purifiers, such as higher-rated MERV filters, can eliminate particles bigger than 0.3 microns, especially animal dander, which is a major allergic trigger. 

While cuddling with dogs or opening a window to allow in some fresh air may be pleasant, doing so can also leave a significant amount of dust, pollen, or other airborne pollutants inside. Allergies, asthma, and other respiratory problems can all be harmed by tiny airborne particles, many of which are so microscopic that they can never be seen. 

However, installing an air purifier will help remove many of these allergens from the air. It’s essential to consider the airborne pollutants you would like to filter and the size of the space in which you’ll be utilizing the air purifier before buying one to lessen allergy symptoms.
