Systems with disposable lters require more frequent lter inspection. Exposure to
humid makeup air can accelerate lter degradation. Replace lters when needed
using the same type of lters as the original.
Supply Air Filters - The supply air lters are 4-inch pleated disposable lters.
Replacement lters are listed in the table below. Do not use any other type of lters.
