When it comes to improving indoor air quality, there are four core strategies: ventilation, humidity control, filtration, and source control. In this video, we'll focus on source control. I'll tell you about one source of indoor pollution that most people aren’t aware of: the drip pan below their refrigerator. (AKA drip tray).

Dust and moisture collect in there and create the perfect environment for mold to grow. When your fridge runs, its fan blows air across the drip pan area, dispersing mold spores throughout your home, and causing health problems such as eczema, asthma, nasal allergies, bronchitis, respiratory infections, and more. This isn't just my opinion: it's backed by lots of scientific research.
