What MERV rating is a 95% filter?
MERV 13 will prevent less than 75% of the 0.3-1.0 micron particles from passing through, MERV 14 will get up to 84%, MERV 15 up to 94% and MERV 16 can trap 95% or more of the smallest particles.
What MERV rating is a 30% filter?

What is filter class G4?
A coarse G4 filter is designed to capture pollen, fog and coarse dust particles (≥10μm). It also captures leaves, insects, textile fibres, sand, ash, mist and hair.
Is MERV 11 or 8 better?
A MERV 11 rated filter captures 85% or better of particles between the sizes of 0.3 and 10 microns. This may not seem like a significant difference compared to the MERV 8 filter, but a MERV 11 is also more capable of capturing between 65% and 79% of smaller particles.
What is the MERV rating of an air filter?
An air filter’s minimum efficiency reporting value (MERV) rating measures how effectively the filter stops dust and other contaminants from passing through the filter and into the air stream. Filters with higher MERV ratings trap small particles more effectively than filters with lower MERV ratings.
What is the difference between Merv 10 and Merv 11?
M 10 filters are easy on air blowers and fans. We recommend MERV 11 filters as our “better” air filter. These air filters are great for people with pets. They remove pet dander and most allergy causing air particles.
What are Merv 17-20 filters?
They are usually reserved for superior commercial applications. HEPA and ULPA filters are represented in the 17 through 20 ratings. ASHRAE no longer recognizes MERV 17-20 values. This level of filtration does fall into the MERV system but they are shown here to add continuity to the overall filter picture.
What is Merv 1 through 4 used for?
M values 1 through 4 are designed to remove large particles. These filters are used primarily to protect equipment. They are used in light industrial and residential applications. Their average efficiency from 3 to 10 micron is less than 20. The Average arrestance is used to determine MERV 1 through 4.
