Question 1

What air filters can M19 instruments test?

Accepted Answer

HEPA/ULPA panel and pleated filters, cabin, and automotive HVAC filters, bag, and pocket filters, respirator, and mask media, and gas-turbine inlet filters.

Question 2

Which air-filtration standards are supported?

Accepted Answer

ISO 16890, ISO 29463, EN 1822, ASTM F2299 and ASTM F2100, plus ASTM F316/D6767 for pore structure — listed per product.

Question 3

Can the analyzer measure both efficiency and pressure drop?

Accepted Answer

Yes. Synchronised upstream/downstream particle counting is correlated with differential pressure, so you get true efficiency across particle sizes together with resistance.

Question 4

Does it support mono- and poly-dispersed challenge aerosols?

Accepted Answer

Yes. The aerosol control system supports mono- and poly-dispersed particles (e.g. PAO, NaCl, DEHS) for standard-specific tests.

Question 5

Is local service available?

Accepted Answer

Yes. Domestic manufacturing gives faster service, ready spares, lower cost and a 2-year extended warranty.
