Delhi's air quality worsens; tips for choosing an air purifier
According to India Today, Delhi-NCR is experiencing high levels of air pollution again, with the Air Quality Index (AQI) reaching hazardous levels. Staying indoors may not provide sufficient protection as indoor air can be more polluted than outdoor air.
To combat this, using an air purifier is recommended. When selecting one, prioritize a True HEPA filter, preferably H13 or H14 grade, which captures 99.97% of particles at 0.3 microns. Look for multiple layers of filtration, including a pre-filter and activated carbon filter, and ensure the Clean Air Delivery Rate (CADR) is suitable for your room size.
This situation highlights the importance of clean air for health, especially in urban areas like Delhi. Individuals with respiratory issues or allergies should pay particular attention to air quality and consider investing in a suitable air purifier.
What to do
- Research air purifiers with True HEPA filters and a good CADR rating for your room size.
- Check the availability and cost of replacement filters before purchasing an air purifier.
- Ensure the air purifier has a filter-change indicator and operates quietly, especially for bedroom use.
- Keep doors and windows closed while using the air purifier to maximize its effectiveness.
- Run the air purifier at a higher speed during times of high pollution or when the AQI is poor.
