Materials

Fitting & Care

Wash with water and mild detergent, then re-spray filter adhesive where the design calls for it.
Keep a spare set so the unit never runs unfiltered during cleaning.

Common Mistakes

Using a metal pre-filter as the final filter.
Re-installing filters wet, which carries water onto the coil.

When Commercial Permanent Metal Air Filter Is Not the Right Choice
