Air purifiers vary in effectiveness based on the space you're using them in and the types of contaminants you're targeting. Here's what to consider when picking the right one:
1. Understand Your Air Quality Needs
Allergies – Look for True HEPA filters.
Odors and VOCs – Choose models with activated carbon filters.
Smoke and PM2.5 – High CADR and HEPA combo is key.
2. Measure Your Room
Match the purifier’s Clean Air Delivery Rate (CADR) to your room size. Larger spaces need higher capacity units.
3. Check Filter Replacement Costs
Some brands offer low-cost filters; others are more expensive. Be aware of the long-term maintenance cost.
