Our Verdict
The Medify MA-40 is the pick for asthma and allergy sufferers who want the highest filter grade available without paying premium brand prices. The H13 HEPA standard and lifetime warranty are genuinely differentiated. The trade-off is higher annual filter costs and no smart features. For medical-grade filtration in a bedroom or home office, it punches above its price.

Pros & Cons
✅ Pros
- H13 True HEPA captures 99.97% of particles at 0.1 microns — the highest filter grade in this price bracket
- Lifetime warranty from Medify — strongest warranty coverage in the category
- AHAM-verified CADR 222 smoke validates the performance claims independently
- Compact 11-inch width fits in tight spaces — good for studios, offices, or bedrooms
- No ionizer or UV — pure mechanical filtration for users who want no additional emissions
❌ Cons
- Filter replacement every 6 months at ~$40 means ~$80/yr — highest annual cost in our comparison
- No auto mode or air quality sensor — manual speed selection only
- Medify's room coverage claims (840 sq ft) are based on 1x ACH — overstated for allergy use
- Brand recognition is lower than Levoit, Winix, or Coway — harder to find in-store
