The EDV-4000 is the first home/office dehumidifier to use innovative rotary desiccant technology to provide high volume dehumidification without requiring a compressor. The unit is safer than compressor-based systems and designed for low maintenance operation, with a high capacity water catch basin that requires only periodic emptying. Also includes a built-in ionizer and bacteria-killing filter to improve air quality, if needed.

The Eva-Dry 4000 dehumidifier is designed for medium to larger spaces of up to 4000 cubic feet, including:

  • Large closets: Eva-Dry prevents damage to fabrics and musty odors caused by excess moisture.
  • Bedrooms and Baths: Absorbs musty odors, and prevents damage caused by excess moisture that can accumulate.
  • Cabins: Keeps the air dry, helping to inhibit mold growth. Ideal for cabins and vacation homes on or near the water.
  • Large RVs and boats: Protect your investment from excess humidity and harmful mold. Helps keep allergens down in areas prone to high humidity.
  • Basements: Keeps basements dry and humidity-free, alleviating condensation build up and dripping.
  • Offices: Protects hardwood floors from moisture and mildew damage.
