Introducing deterministic non-captures (where there are a a class of particles not captured), can be a problem, as those will not be affected by the purifier.
With something like a MERV 14 HVAC filter there aren’t any particle sizes that it deterministically doesn’t capture, though it does have lower efficiency at some sizes (75% at worst performing size).
