It’s that time of year again! Time to change your air filter so you can breathe easy (literally and figuratively), knowing that your air filtration system is doing its job! But let’s be honest. The air filtration aisle of a home improvement store can be a little overwhelming. All the air filter options with different sizes, thicknesses, and MERV ratings, OH MY! The question you probably have at that point is, “what is a MERV rating, and which one do I need for my home”?
MERV stands for minimum efficiency reporting value. These ratings measure the amount and size of particles that it captures. The higher the MERV rating, the thicker the filter, therefore the more large particles it will trap. But pro tip – you may want to rethink choosing a filter with the highest MERV rating as they tend to add more resistance against airflow. The more resistance, the more energy your HVAC system will use. Curious about which rating you need? Check out these ratings and what each means.
Filters with this MERV rating provide the bare minimum protection. They are thin, flat, and catch contaminants such as pollen, dust mites, roach debris, and other particles smaller than 10 microns.
Filters with this MERV rating provide medium-quality protection. They capture particle size 3.0-10.0 microns, including mold and pet dander. These filters are the suggested size for most residential homes.
Filters with this MERV rating provide above standard protection in residential homes. They can help control allergies, asthma, and other respiratory conditions. They block out larger particles from sizes 1.0-3.0, including most molds, dust, and pet dander.
Filters with this MERV rating provide superior protection and block out viruses, smoke, bacteria in addition to dust and mold. They capture particle sizes from 0.3-1.0 and are typically used in hospitals.
The moral of the story, choosing the right MERV rating for your air filter plays a big part in your health and indoor air quality. Let Avis Home Solutions help you make the right decision and call us today at 949-328-3374 to schedule an air cleaner service!
