1st Stage Pre Filters

A pre filter is the primary layer of filtration that collects large particles before they reach the HEPA filter. Eliminating these larger particles, dust and hair extends the life of your HEPA filter. Occasional vacuuming of the exterior of the unit will help extend life of the filters. Frequent pre filter changes will also prolong the HEPA filter life.
