Summary
The Medify MA-125 is Medify’s big-room bruiser: a wheeled console that can genuinely hit 5 ACH in ~800 ft² thanks to an ENERGY STAR-verified 538 CFM (Cubic Feet per Minute) CADR (Clean Air Delivery Rate). Its H14-grade filter, optional UV-C, and sub-35 dB low speed make it a strong wildfire-smoke scrubber for family rooms—if you can stomach ~$250 per year in filters and occasional 60 dB fan roar when you crank it past speed 6.
Here's what this purifier does best
- Serious airflow: >500 CFM (Cubic Feet per Minute) smoke CADR (Clean Air Delivery Rate) cleans large living rooms or open basements quickly.
- H14 HEPA + pellet carbon: Hospital-grade particle capture and real VOC/odor adsorption without an ionizer.
- Toggleable UV-C: Adds germicidal protection and can be switched off to avoid extra lamp noise or energy draw.
- Nine fan steps + 24 h timer: Fine-tune noise vs. airflow and schedule operation without an app.
- Caster wheels: 45-lb chassis rolls between rooms instead of being lugged.
Consider these trade-offs
- Pricey upkeep: Two $130+ cartridges a year push annual costs near $250.
- Loud on high: 58–63 dB at top speeds—louder than normal conversation; best run while the room is empty.
- No Wi-Fi or app: Competes in a price tier where smart control is common.
- Marketing overreach: 4,000 ft² coverage claim is based on 1 ACH (Air Changes per Hour)—ignore and size to ~800 ft².
- No AHAM seal: Conflicting CADR numbers (538 vs. 781 CFM) make apples-to-apples comparison tricky.
