Pre-Filters and Why They Are Important

This will be the first in a series of posts detailing current observations and issues we come across in the field as certifiers. This first topic concerns device and fan filter unit prefilters.

The majority of positive and negative isolators, laminar flow units, non-ducted fan filter units, balance enclosures, Class I biological safety cabinets, and some Class II B2 biological safety cabinets have prefilters. Prefilters are critical to help remove larger dust particles and extend the life of the HEPA filter, the blower motor, and components. If prefilters are not changed out regularly, they can cause imbalanced airflows and pressures in the unit, thus causing the device airflows to fall outside the manufacturer’s acceptable range of protection for the patient, product, personnel or environment.
