About Crawl PPD
Crawl PPD provides transparent comparisons of crawl-space dehumidifiers to help homeowners and contractors make informed decisions.
Mission
The crawl-space dehumidifier market lacks clear, up-to-date comparison data. Manufacturers publish AHAM PPD ratings at test conditions (80°F / 60% RH) that don't reflect real crawl-space performance. Street prices fluctuate weekly. Warranty terms and pump specifications hide in spec sheets.
Crawl PPD tracks this data systematically: AHAM PPD, minimum operating temperature, built-in pump lift capacity, warranty length, filtration options, and current street prices from major retailers.

Important Disclaimer
AHAM pints-per-day ratings (80°F / 60% RH) differ significantly from actual crawl-space output. Crawl spaces typically operate at cooler temperatures (55-65°F) and higher humidity (70-85% RH), reducing effective capacity by 20-40%. Always consult manufacturer performance curves for your specific conditions.
