Dehumidifiers & Air Purifiers
ENERGY STAR® certified air purifiers and dehumidifiers boost your comfort and safety by improving air quality.
Dehumidifiers combat mold and rot by removing moisture from indoor air, making it fresher and your space more comfortable. Air purifiers (also called room air cleaners) improve air quality by filtering out smoke, dust, dander, and pollen. If you’re shopping for one of these technologies, look for ENERGY STAR certified models—at least 15% more efficient for dehumidifiers, about 25% more efficient for purifiers, and just as effective as standard models.
Choosing the Right Size Dehumidifier
Dehumidifiers are rated by the amount of water they remove from the air over 24 hours—anywhere from 10 to 70 pints. Use this chart from ENERGY STAR to select the right size dehumidifier based on the square footage and humidity of your space. A larger tank may make sense if you’re unable to empty it frequently and can’t connect it to a drain. But keep in mind that mold can grow in any water basin that’s not regularly emptied and cleaned out.
- Choose the correct size based on your square footage and current humidity level
- A dehumidifier’s energy factor (EF) measures overall efficiency: look for a minimum 1.85 EF
- Some ENERGY STAR certified models are rated for use in colder temperatures, as low as 42 degrees
