It also captures leaves, insects, textile fibres, sand, ash, mist and hair. 0.4μm and larger particles include mould & plant spores, pet dander, textile dust, skin flakes, yeast cells, insecticide dust and most bacteria.

What do the numbers mean on air filters?

Filter efficiency and performance is often indicated by the filters’ minimum efficiency reporting value, or MERV rating. Standard MERV values range from 1 to 16, with the number serving as an indicator of how well the filter will remove material from the air. Higher MERV numbers indicate better filtration.

How do I know my MERV rating?

MERV ratings range from 1 to 20, with lower ratings denoting a lower-quality filter.

MERV 1-4 Filters: Filters with a MERV rating of 1 to 4 do little to trap harmful particles in your home’s air.
MERV 5-8 Filters: MERV ratings of 5 to 8 indicate a medium-quality filter that’s sufficient for most homes.

Is MERV 16 too restrictive?

Filters within a MERV rating of 17-20 are almost never necessary in a residential home. A MERV rating of 13-16 is considered hospital level air quality, so it is unlikely your home needs any more than that.

What is the MERV scale?

MERV stands for Minimum Efficiency Reporting Value. MERV ratings are on a scale of one to 20 depending on the minimum size of the particles a filter can be expected to capture: A filter with a MERV rating of one to four captures particles greater than 10 micrometers.

What is M6 filter?

M6 is for high efficiency filtration in heating, ventilation and air conditioning systems. As prefilters for high efficiency absolute filters.
