For over 50 years, Aprilaire dehumidifiers have been the ultimate solutions for humidity control throughout your home. Available in basement and whole house models, these dehumidifiers control excess humidity to stop mold and mildew growth, eliminate allergens, and put an end to humidity-related damage to your interior. Aprilaire whole house dehumidifiers install as part of your home’s central HVAC system to dehumidify all the rooms in your room as you condition or heat your air. Aprilaire basement dehumidifiers are freestanding units designed to extract damaging moisture from your basement or crawl space.

Aprilaire dehumidifiers are proudly made in the USA.
