Maximum PPD and AHAM PPD measure different conditions.

Maximum or saturation removal reflects performance in very humid test conditions, while AHAM removal is a more standardized moderate-condition rating. Both are useful context, but a higher maximum PPD alone does not determine which unit is the better fit for a specific crawl space.

Capacity and coverage values shown here are manufacturer-reported specifications. Manufacturer maximum coverage is not a DrySpace sizing recommendation.
