Ait Filters - testing used filters for efficiency?

Hoping this is the right section to post this in,

We are spending a lot of money on air filters for our main warehouse HVAC units. We are a spice bottling company so dust/particulate buildup is definitely an issue. My boss suggested finding a company that tests used filters to assess the efficiency of the filters after a few weeks use. Does anybody know of a service for this?

Good day, what are you testing for? If it is microbial tests any micro lab can do it

What you need is the swab which comes with buffer. You need to swab your filter and send it for analysis

I deduce you are installing new filters.

Required filter ratings are afaik typically assessed from published lists based on specific product type/environment.

i would have anticipated that a reputable supplier should be capable of directly handling yr query ?
