Summary
Indoor air can be more polluted than outdoor air because of dust, mold, pet dander, and chemicals. The Environmental Protection Agency (EPA) and studies suggest that using air purifiers with HEPA filters can help clean indoor air and reduce health issues like allergies and asthma. It is important to choose air purifiers based on the size of the room and filter efficiency.
Key Facts
- Indoor air can contain more pollutants than outside air, such as dust, mold, and pet hair.
- The EPA notes that many people spend 90% of their time indoors.
- Air purifiers with HEPA filters can reduce tiny particles that can cause health problems.
- HEPA filters are designed to capture most small particles that can harm health.
- The Clean Air Delivery Rate (CADR) measures how effectively a purifier cleans the air.
- Choosing the right air purifier depends on room size and CADR rating.
- High-CADR models are recommended for larger rooms with more air cleaning needs.
- Budget-friendly air purifiers are available for smaller rooms and still meet HEPA standards.
