What is MERV 13 equivalent to?
MERV 11 vs MERV 13 MERV 13 air filters provide even additional filtration power against fine particle matter compared to MERV 11 filters. Additional benefits of MERV 13 air filters are that they can filter out smoke, airborne viruses, and smog.
What is H14 HEPA filter?
H13-H14 HEPA are within the highest tier of HEPA air filtration and are considered medical-grade. “A HEPA grade of H13 can remove 99.95% of all particles in the air measuring 0.2 microns in diameter, while a HEPA grade H14 removes 99.995%,” says Nagl.
What is a G4 grade filter?
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. (Note: 10µm is 0.01mm.) Medium filters were classified according to the average efficiency (Em) of 0.4μm particles.
Does MERV 13 filter out viruses?
Minimum Efficiency Reporting Values, or MERV, reports a filter’s ability to capture particles. Filters with MERV-13 or higher ratings can trap smaller particles, including viruses.
What is the MERV rating of a G4 filter?
6-8
Air filter selection chart and Performance Ratings

What is an F9 filter?
A F9 minipleat filter is an effective air filter for offices, schools and public buildings. As minipleat filter specialist we can supply F9 air filters in various dimensions, frames and applications. Upgrade your ventilation and filter efficiency with minipleat filters.
What is the difference between F7 and F8 filters?
Even a G4 bag filter will become F8 by the end of its like, this is the mechanical process in these filters. As they catch more particles the air can only move through smaller holes and the filter becomes finer. The difference between the F7 & F8 is very minor and completely unnecessary for Home ventilation.
Can you breathe MERV 13?
The viral nuclei contained within the water vapor is what the MERV 13 filter material is rated as being able to filter. You can use a higher rated MERV filter in a pocket mask if you can obtain it, however it will be harder to breathe through.
What is the new en779 air filter standard?
The standard replaces the old 2002 standard which classifies coarse and fine air filters. In EN779:2002 air filters were classified on their average efficiency across the life of the filter, allowing the filter to underperform in its new and clean state.
What is enenen779?
EN779:2012 is the new European Standard for air filters and will come into effect by the end of 2012. The standard replaces the old 2002 standard which classifies coarse and fine air filters.
What is the difference between en779 and en779 2012?
EN779:2012 only calls for Minimum Efficiency on filters of grades F7 to F9 and to clearly define this, filters previously classified as F5 and F6 are now changed to M5 and M6 in a Medium Filter Category. Note: The characteristics of atmospheric dust vary widely compared to those of the synthetic dust used in the EN779 tests.
What is en 7779?
EN779:2012 is a laboratory test and is not predicting real life performance Energy rating system contributes to a lower cost environmental friendly system The filter is the base of the success
