Medify MA-112 vs Smart Air Blast Mini Mk II
Quick take: The Medify MA-112 costs $100 less; the Medify MA-112 moves more air (561 CADR, 40% more cleaning power); the Smart Air Blast Mini Mk II costs about $125 less per year in filters — over five years that often outweighs the sticker gap; the Medify MA-112 is the quieter bedroom unit (35 dB on sleep mode); the Medify MA-112 has a particle sensor with auto mode, so it actually responds to cooking smoke and pollen spikes on its own.

| Rating | — | — |
| Type | Extra-Large | Extra-Large |
| CADR (smoke) | 561 CFM | 400 CFM |

| Filter Cost / Year | $274 | $149 |
| Filter | Dual pre-filter + H13 True HEPA + activated carbon (two filter sets, dual intake) | Single oversized H13 HEPA panel (23" x 23") + optional VOC/carbon filter |

| Auto Mode | Sensor + auto | Manual only |
| Ionizer | None | None |
| WiFi Control | None | None |
| Weight | 33.5 lbs | 59 lbs |
| Maintenance | This is the trap: the dual-intake design uses a full filter set rated at only 2,500-3,000 hours - roughly 4-6 months of real use - and a genuine replacement set runs about $137, so honest upkeep is ~$274/yr, more than half the purchase price annually. Third-party sets cost a third as much, but Medify's lifetime warranty explicitly requires registering within 30 days and replacing genuine filters every 4-6 months, so cheap filters void it. Wipe the sensor port and glossy panel regularly; at 33.5 lbs it's not a unit you'll casually move. | One enormous 23-inch H13 HEPA panel lasts a rated 13 months at $149.99 (add the optional VOC filter and you're at ~$235/year); a washable pre-filter behind twist screws catches the big stuff first. No app, no DRM, no subscription — just a rear dial and lockable wheels. The real ownership cost is electricity: 122.7W at top speed runs about $136/year 24/7, pushing total running cost near $285. |
