When it comes to air filtration, the Minimum Efficiency Reporting Value (MERV) is an important factor to consider. MERV ratings are used to measure the effectiveness of air filters in capturing particles of different sizes. A Merv 8 filter is one of the most common ratings, and it is effective in controlling mold spores, hairspray, dust, and other particles between 0.3 and 10 microns in size. MERV 8 filters are 90 percent efficient on particles that are 3 to 10 microns in size.
This makes them suitable for most residential, commercial, and industrial settings. They are also a good choice for households with pets or smokers, as they can help eliminate odors. However, if you are concerned about outdoor air pollution or have family members with respiratory problems, then a higher merv rating might be a good idea. A Merv 13 filter is an excellent choice if you want to create a healthier home environment and protect your family from airborne viruses, smog, and smoke.
When choosing an air filter, it is important to follow the manufacturer's recommendations for maintenance and replacement. If you're not sure which MERV rating to use, you can have professionals make a recommendation for you during a routine HVAC basic maintenance visit. Overall, MERV 8 air filters are an effective way to trap most indoor particles that could weaken people with asthma and allergies or cause long-term respiratory problems. They are also suitable for homes with pets or smokers, as they can help eliminate odors.
However, if you are concerned about outdoor air pollution or have family members with respiratory problems, then a higher merv rating might be a good idea.
