Pleated filters provide prefiltration in compatible negative air machines and air scrubbers, capturing particles before they reach the HEPA stage. Spycor Environmental offers Omnitec MERV 11 primary pleated filters, Abatement Technologies 2-inch particulate prefilters and second-stage filters, and OmniCleanAir replacement filter kits.
Remediation contractors and facility maintenance teams can compare options by machine model, filter dimensions, filtration stage, rating, and pack quantity. Confirm the specified replacement and kit contents before ordering, not every listed filter has the same MERV rating or installation position.
