Families who use quality, properly fitted air filters in their home – and replace them regularly throughout the year – are more likely to reap the benefits of superior indoor air quality. That cleaner air will go a long way toward helping your family enjoy a happy, healthy home that’s resistant to respiratory irritants, asthma triggers, allergens and serious long-term conditions.

Proper Air Filters Help Reduce:

  • Dust and Dust Mites
  • Pollen
  • Pet Dander
  • Mold Spores
  • Gases, Chemicals and Smoke
  • Misc. Air Particles

Two acronyms you’re likely to see while researching air filters for your home will be MERV and HEPA. These are differing rating systems for air filters that give you a quick idea for how efficiently they filter irritating particles from the air you breathe.


MERV stands for Minimum Efficiency Reporting Value and is the rating measurement system used for whole home solutions--MERV16 being the highest. The higher the number, the more efficient the air filter, based on how small of an air particle they can pull from the air. According to, high-efficiency MERV13-16 air filters can filter particles as little as 0.3 microns with 75% efficiency.


HEPA stands for High Efficiency Particulate Air Filter and is a rating measurement used for portable or room air purifiers. You can think of these as MERV17-20. These filters are made to filter air at an exceptionally high scale. In fact, HEPA filters generally remove 99.97% of the invisible intruders in your home down to 0.3 microns. However, a filter rated this high isn't ideal for whole home HVAC systems as they create too much static pressure--or the resistance to airflow--which can cause damage to your systems fan. That said, fans in room air purifiers are specifically designed to handle this type of pressure, and therefore, are able to handle HEPA filters, providing a supplemental burst of fresh air.

Equip your healthy home with the highest rated filters possible for optimal indoor air quality.

Do’s & Don'ts


use an air filter designed for your needs

Particulate removal is based on your lifestyle and needs. The American Lung Association recommends filters rated MERV 11 or higher in whole home systems. Aprilaire offers air filters that can be tailored to your family's specific needs.


utilize a room air purifier with HEPA filters

Again, based on your needs, use a room air purifier anywhere your home needs fresher air. Make sure your room air purifier uses a HEPA filter, tailoring its use to your family's needs. Aprilaire room purifiers can help you filter specific particulates from your home.


use air filters that aren’t genuine to the system’s manufacturer

Generic air filters won’t always fit properly, meaning your healthy home’s central air system isn’t living up to expectations, decreasing indoor air quality in the process. For example, genuine Aprilaire filters offer a Pure Fit Promise that your filter will fit snugly with Aprilaire systems, offering more efficient air cleaning.


routinely replace your air filter as recommended by the manufacturer

If you’re experiencing a particularly bad allergy season or are kicking up more dust at home due to a renovation, consider replacing your air filter sooner than the manufacturer recommends. You should also consider clearing dust build-up in your system once a month.


forget to ventilate your home

Ventilation allows airborne debris to cycle through your healthy home, meaning the air is less stagnate and that airborne debris is more likely to be captured by your air filter, increasing indoor air quality in the process. Without ventilation, dust settles into nooks and crannies that can have an effect on long-term health.

Indoor air pollution causes an estimated 4.3 million premature deaths each year.”


For a healthy home, be sure to consider what type of air filters you use and how efficient they are at removing air particles to increase indoor air quality. This will go a long way toward making sure your family’s respiratory wellness is secure while staving off allergy and asthma triggers. Lastly, steer clear of generic-brand air filters that sacrifice quality and efficiency. Use genuine parts from the manufacturer such as Aprilaire’s Pure Fit Promise air filters to ensure a healthy home.
