Do i need merv 8 or merv 11?

MERV 8 vs MERV 11 AIRFLOW The better an air filter is at trapping particles, the faster it will reach its maximum. If you're concerned about the effects of breathing fine air particles, that's another reason to choose a Merv 11 air filter instead of a merv 8 air filter. The fine air particles are 2.5 microns and smaller. MERV 11 filters are more efficient than MERV 8 filters because they can capture smaller particles.

They offer additional protection against pet dander, dust mites, automatic emissions and dust that damages the lungs. This is a good choice for homes with pets or those looking for even better air quality than what the MERV 8 can offer. It is also our most popular type of air filter. Since a high merv rating means that more particulates will be removed from the air, you can first think about using air filters with the highest MERV rating.

It should also be noted that filters at the lower end of the MERV scale are not even tested for efficiency in capturing E1 and E2 particulate matter. The MERV scale is not linear; the difference between a MERV 6 and a MERV 8 is almost double in the percentage of particles captured. The worst percentage of the six tests is selected as the official measure used to determine the MERV rating of a filter. Merv 13 filters, for example, also remove bacteria, tobacco smoke, car fumes, insecticide dust, pet dander and more.

The American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) uses particle size to classify MERV values. You are now equipped to monitor your air filter and change it regularly with the right MERV value for your home and family. If you want you to at least clean your air and handle dust, mold, pollen and bacteria, then a MERV 8 will do the job. At the heart of an optimally functioning HVAC system is an oven filter with the right MERV rating for you.

However, this depends on the MERV rating you choose for your home, along with a couple of other factors. Well, merv's ratings range from 1 to 20, with 1 being the lowest level of filtration and 20 being the highest. This page will compare MERV ratings 8, 11, and 13, and explain how to choose the right MERV rating for your home.
