Asit Kumar Mishra @akm76.bsky.social · 22/10/2023For example, have a look at the performance of different MERV rated filters, MERV 8 - 16 (hpac.com/industry-per...) For MERV 16, you can't say 1 micron particles will be trapped - they almost certainly will be, but not a definitive YES. 5/ 140 0
Asit Kumar Mishra @akm76.bsky.social · 22/10/2023Similarly, for MERV 13, particles between 0.3 and 1 microns, have about a 75% chance of getting trapped. Again, not a definitive NO or YES. More than an even chance, so not too shabby. 6/ 120 0
Asit Kumar Mishra @akm76.bsky.social · 22/10/2023At the same time, if you are interested in particles around 1 micron size, you would not even think of getting a MERV 8 filter. Not that they would not filter anything at 1 micron. Just that the values are not of practical interest and MERV 8s don't get rated at that size 7/ 130 0
