Filtration Technology
The MA-40 uses a medical-grade H14 HEPA filter, which captures 99.95% of airborne particles at 0.3 microns , a meaningful upgrade over the H13 standard (99.97% at 0.3μ) because H14 is tested at the most penetrating particle size and maintains efficiency down to 0.1 microns. The integrated UV-C light adds a secondary layer of purification by targeting airborne pathogens as they pass through the unit.
This dual-action approach puts the MA-40 in the same filtration tier as units found in hospitals and clinics, which is uncommon for consumer-grade purifiers in this tier.
Noise & Performance
With a dust CADR of 380 CFM, the MA-40 can cycle air in a 450 sq ft room approximately 4 times per hour, or cover its full 1,793 sq ft rating with one complete air change per hour. Customer feedback on noise is mixed , some find it acceptably quiet on lower settings, while others report it gets noticeably loud at higher speeds.
For bedrooms, this unit may be better positioned in a living room or office where ambient noise is less of a concern.
Smart Features & Controls
The MA-40 uses manual controls with multiple fan speed settings but does not include an air quality sensor, auto mode, WiFi connectivity, or app control. This is a straightforward, no-frills interface , you set the speed and it runs.
For users who prefer simplicity and reliability over smart features, this is a non-issue, but those who want automated adjustments or remote control from their phone will need to look elsewhere.
Filter Maintenance
Medify recommends replacing the filter every 4 months under normal use, with the replacement filter available under model number B07MTQFFNT. The unit includes a filter change indicator to take the guesswork out of maintenance timing.
Filter swaps are straightforward , the panel design allows quick access without tools, keeping ongoing maintenance simple and predictable.
Who Is This Air Purifier For?
Ideal For
- ✓ Large home owners needing whole-house coverage , 1,793 sq ft reach handles open-concept layouts, great rooms, and multi-room apartments
- ✓ Allergy and asthma sufferers who want medical-grade H14 filtration that captures particles down to 0.1 microns, including pollen, dust mites, and fine pet dander
- ✓ Pet owners in spacious homes , the high CADR of 380 CFM moves enough air to tackle pet dander and hair across large living rooms and connected spaces
- ✓ Schools, universities, and offices looking for a certified, high-capacity purifier with Energy Star efficiency and CARB compliance
Not Ideal For
- ✕ Smart home enthusiasts who want app control, voice assistant integration, or automated air quality response , this unit is manual-only
- ✕ Light sleepers needing a bedroom purifier , without a verified quiet mode, higher fan speeds may be disruptive at night
- ✕ Users primarily concerned with smoke odors or cooking smells , the unit lacks a dedicated activated carbon filter for gas-phase pollutants
Setup is minimal , remove the unit from packaging, unwrap and install the pre-included filter, plug in, and select your fan speed. Most users report being up and running in under 5 minutes with no tools required.
Remove all plastic wrapping from the filter before inserting , a common oversight that blocks airflow entirely
Run the unit on the highest setting for the first 1-2 hours to clear any initial manufacturing odors
Medify offers a USA registered Lifetime Warranty, one of the most generous in the air purifier market. Registration is required to activate the full warranty, so be sure to complete it promptly after purchase.
FAQ
Does the Medify MA-40 remove wildfire smoke effectively?
The H14 HEPA filter excels at capturing fine smoke particles down to 0.1 microns, and with a CADR of 380 CFM it can cycle air quickly across large spaces up to 1,793 sq ft. However, it lacks a dedicated activated carbon filter, so while particulate smoke is handled well, lingering smoke odors may not be fully eliminated.
How loud is the Medify MA-40 and can I use it in a bedroom?
Customer feedback on noise is mixed , lower fan speeds are generally quiet enough for daytime use in living rooms and offices, but higher speeds produce noticeable noise. For bedrooms, light sleepers may find it disruptive.
It's best suited for large common areas where some background noise is acceptable.
How often do I need to replace the filter and how much does it investment?
Medify recommends filter replacement every 4 months under normal use. The replacement filter model is B07MTQFFNT.
The unit has a built-in filter change indicator so you'll know exactly when it's time, and swapping the filter takes just a couple of minutes without tools.
What's the difference between H14 and H13 HEPA filters?
H14 HEPA filters capture 99.95% of particles at the most penetrating particle size, while H13 captures 99.97% at 0.3 microns. The practical difference is that H14 is tested more rigorously and maintains higher efficiency across a broader particle size range, down to 0.1 microns.
It's the same grade used in hospitals and clean rooms.
Can the Medify MA-40 cover my entire apartment or home?
With 1,793 sq ft of coverage and a CADR of 380 CFM, the MA-40 can handle most apartments and large living rooms in a single unit. For whole-house use in homes over 1,800 sq ft, you may want a second unit or to move it between spaces.
It delivers roughly one full air change per hour at maximum coverage.
Does the Medify MA-40 work with Alexa or Google Home?
No, the MA-40 does not have WiFi, app control, or voice assistant integration. It operates via manual controls only.
If smart home compatibility is a priority, you'll need to consider other models that offer WiFi connectivity and app-based control.

It sacrifices smart features and quiet bedroom operation for raw purification power , a trade-off that makes sense for large homes, apartments, offices, and schools where clean air coverage matters more than app control.
Best for large homes, open-concept apartments, and offices needing medical-grade H14 HEPA filtration across 1,793 sq ft
Consider alternatives if you need smart home integration, auto mode, or a whisper-quiet bedroom purifier
