Buyer’s Guide: How to Choose the Right Smart Air Purifier
Here are five key factors to help you pick the best air purifier for your needs:
1. Room Size
Always match the purifier’s coverage area with your room size. A unit designed for 300 sq. ft. won’t perform well in a 600 sq. ft. space.
2. Filter Type
Go for models with True HEPA filters to trap fine particles and allergens, and Activated Carbon filters for odors and gases.
3. Smart Features
Useful features include:
- Real-time air quality sensors
- App control and reporting
- Auto-adjusting fan speeds
- Voice assistant integration
4. Maintenance and Filter Cost
Check how often filters need to be replaced and their price. Some smart purifiers notify you when it’s time to change filters.
5. Noise Level
Look for a quiet or sleep mode if using the unit in bedrooms or nurseries.
