You want to make a difference in the air your family is breathing, but you’re not sure whether your air filter is actually doing its job. We totally understand because your family’s health is a priority.
First off, you need to decide what MERV rating fits your family’s needs. The range of a filter’s effectiveness at removing allergens and other particles is determined according to a number system. Filters with a lower number are typically inexpensive, but they aren’t as effective at removing smaller particles. The higher the MERV rating, then the smaller the particles the air filter is able to remove.
According to an article by the University of Illinois Extension, “some filters remove large, heavy particles from the air but allow smaller particles to flow through.” Therefore, it’s important to understand whether your air filter is able to remove both large and small particles or is mainly intended to remove large particles.

The easiest way to help minimize the amount of allergens in your home is make sure you change your air filter on a regular basis. If you don’t change your air filter, then you even be worsening your allergies.
Filters with a MERV rating of 9 or higher are better for individuals who suffer from allergies.

Allergy sufferers may want to look into getting an electronic air cleaner since it is able to remove the most particles from your air. We’ve broken down the filtering capabilities of filters based on their ability to remove sub-microns (i.e. dust and animal dander).
