Medify Air has carved out a strong niche by offering medical-grade H13 HEPA filtration with higher CADR-per-dollar ratios than most mid-range competitors. The MA-40 ($349, 330 CADR, 840 sq ft) and MA-25 ($199, 250 CADR, 500 sq ft) both feature dual air intake, H13 HEPA with ionizer, and AHAM-verified performance that competes with brands costing significantly more. Their flagship MA-112 pushes CADR to an impressive 500+ CFM for massive spaces.
Medify positions themselves as the "clinical grade at consumer prices" brand. Their marketing emphasizes the H13 HEPA standard (the same grade used in hospitals and cleanrooms), and all models feature dual-intake airflow designs that pull air from both sides simultaneously. It is an emerging brand worth serious consideration — especially the MA-25, which offers outstanding value in the $200 range.
Medify Filtration Technology
H13 True HEPA with Dual Intake
Every Medify purifier uses H13 True HEPA filtration (99.97% capture at 0.3 microns) with a three-stage system: pre-filter mesh, activated carbon layer, and the H13 HEPA media. The filters are combined into a single replaceable cartridge.
The dual-intake design is Medify's signature engineering feature. Rather than pulling air from one side, each unit draws air from both the left and right panels simultaneously. This doubles the effective filter surface area exposed to incoming air, reduces the work each fan has to do, and allows for higher CADR at lower noise levels compared to single-intake designs.
Ionizer Function
All Medify models include a negative ionizer that can be toggled on or off independently. When activated, it releases negative ions that charge airborne particles, causing them to cluster and settle out of the air faster. Ozone output is CARB-certified at well below the 0.05 ppm safety threshold.
Medical-Grade Claims: Medify's use of "medical-grade" refers to the H13 HEPA filter classification, which is indeed the standard used in hospitals and cleanrooms. However, the purifier unit itself is not an FDA-regulated medical device. The filtration media is genuinely H13 grade, which is the same specification used by Dyson, Levoit, and Coway in their current models.

Model Deep Dives
MA-112 V2.0: The Industrial-Strength Home Purifier
The MA-112 is Medify's most powerful unit, designed for very large rooms, open-concept homes, and commercial spaces. At 500+ CADR covering 2,500 sq ft, it outperforms virtually every residential purifier on the market including the Coway Airmega 400 (350 CADR) and Alen BreatheSmart 75i (347 CADR).
The dual-filter design uses two large H13 HEPA cartridges, one on each side. The unit is noticeably larger than typical home purifiers (approximately 28 × 16 × 16 inches, 30 lbs) and is designed to sit on the floor in a central location. At $499, it offers extraordinary CADR-per-dollar value for very large spaces.
Noise on the highest setting (66 dB) is loud — similar to a dishwasher. On the lowest setting, 28 dB is reasonable. Auto mode is not available — speed is manually controlled.
MA-40 V2.0: The All-Around Performer
The MA-40 is Medify's most popular model and strongest overall recommendation. At $349 with 330 CADR and 840 sq ft coverage, it competes directly with the Coway Airmega 400 ($350, 350 CADR) and Alen BreatheSmart 45i ($329, 245 CADR).
The dual-intake design keeps the MA-40 compact despite its high CADR output. Noise ranges from 26 dB (low speed, very quiet) to 56 dB (maximum, moderate). The unit includes a child lock, timer (1/2/4/8 hours), three fan speeds, and the optional ionizer.
MA-25 V2.0: The Value Champion
The MA-25 at $199 with 250 CADR is Medify's best value play. It covers 500 sq ft in a compact form factor and offers dual-intake H13 HEPA filtration at a price that undercuts the Coway Airmega 250S ($300) while delivering comparable CADR.
This is the model to buy if you want Medify's dual-intake advantage without the MA-40's larger size and higher price. For bedrooms and medium living rooms, the MA-25 is an excellent choice.
MA-15 and MA-14: Budget Entry Points
The MA-15 ($129, 150 CADR) and MA-14 ($99, 120 CADR) are Medify's compact, single-intake models for bedrooms and small rooms. They use the same H13 HEPA media but in single-filter configurations. Performance is solid for the price, competing with the Levoit Core 300S ($99, 145 CADR) and Core 200S ($79, 118 CADR).
