Does MERV 8 filter smoke?

However, a MERV 8 filter captures less than 20% of particles smaller than 0.3 microns. That means things like pet dander, smoke, and some airborne bacteria are likely to get through a MERV 8 filter.

What are 30% filters?

For instance, a 30% filter (based on arrestance) means that 30% of the weight of the dust has been captured. Depending on the size of the dust particles the actual number of particles (and hence the percentage of particles) captured may be substantially less.

What is a HEPA rating?

A HEPA is the creme de la creme of air filters with an equivalent rating of a MERV 17 or higher. A HEPA filter at a MERV 17 rating will trap 99.97% of air particles that are 0.3 microns in size, but capture an even higher percentage of particles smaller or larger than that size.

What MERV rating is best?

According to the ASHRAE, the best rating for residential HVAC systems is MERV 13. But before you upgrade your filter, make sure your specific system can accommodate that rating. A higher MERV rating often means lower airflow, which can cause the system to work harder—use more energy—to do its job.

What MERV filter does carrier recommend?

Selecting a good quality filter with 12 – 16 MERV to remove a high percentage of offending particulates. Be sure to check your filter at a minimum of once per month.

Is MERV 5 Good enough?
