DIY Smart Home Air Cleaner

Air filtration devices can help remove unwanted odors, particles, and more. The simplest of such units typically incorporate a fan and one or multiple filters. Depending on the filter you use, you can achieve different effects. This article discusses a homemade air filtration device that uses a readily available and cheap 12V computer fan and an activated charcoal filter. This filter traps dust particles and also filters smells that linger in the air. In addition, the device incorporates an air-quality sensor. An additional Arduino board controls the fan speed depending on the air quality in the room.
