Everything about indoor air quality.
The importance of clean and healthy air
Poor air quality has a major impact our health. In many cases, indoor air is more polluted than outdoor air. Because we spend most of our time indoors these days, exposure to poor air quality puts us at risk for a variety of diseases such as stroke, heart disease, lung cancer, and both chronic and acute respiratory conditions.

How do you measure air quality?
Indoor air pollution is often invisible. Tiny particles are 30 times smaller than a human hair, so you can’t rely on sight alone. The easiest way to monitor air quality is with a PM2.5 laser sensor. This sensor, built into devices like the Bright 2, measures fine particulate matter in micrograms per cubic meter (µg/m³).
- 0–20 µg/m³: Excellent to good air quality
- 21–75 µg/m³: Moderate to slightly unhealthy
- 76–999 µg/m³: Unhealthy to hazardous
By keeping track of these levels, you can take action to improve the air you breathe at home, protecting your health and comfort.
How to improve poor indoor air quality
If the air in your home feels polluted, an air purifier can help. These devices draw in air, remove pollutants with a multi-layer filter, and release clean air back into the room. Some purifiers also release negative ions, which help fine dust particles settle so they can be captured more easily.
To choose the right air purifier, check the Clean Air Delivery Rate (CADR). The CADR shows how many cubic meters of air the purifier can clean per hour. A higher CADR means the device can clean the air faster and is better suited for larger rooms. Always match the CADR to your room size for optimal results.
