Then again, filters that exceed the necessities of the ‘HEPA air filter’ and capture over 99.999% of particles are referred to as ‘ULPA filters’ or ‘extremely-minimal penetration air filters’.

[citation desired] This refers to their Minimal Efficiency Reporting Value (MERV) score.[citation necessary] These ratings are used to level the flexibility of an air cleaner filter to get rid of dust through the air as it passes through the filter. MERV is an ordinary utilized to evaluate the overall efficiency of a filter. The MERV scale ranges from 1 to sixteen, and measures a filter's capability to get rid of particles from ten to 0.3 micrometer in size. Filters with higher ratings don't just clear away additional particles through the air, but they also remove lesser particles.
