- And many are overpriced for what they deliver

What Actually Matters in an Air Purifier
1. True HEPA Filtration
Captures:
- Dust
- Pollen
- Mold spores

2. Activated Carbon (for toxins)
Removes:
- VOCs
- Odors
- Chemical pollutants
👉 This is where many cheaper units fail
3. Room Size Coverage
Match purifier to room size—or it won’t work effectively
4. Air Changes Per Hour (ACH)
Higher ACH = cleaner air faster
