Filter System

Filtration Technology

The MA-40 uses a three-stage filtration system: a pre-filter captures large particles like pet hair and dust, the H13 True HEPA filter removes 99.95% of airborne particles down to 0.1 microns (including pollen, mold spores, and bacteria), and the activated carbon filter absorbs odors, smoke, and VOCs. The H13 grade places this above standard True HEPA (H11/H12) filters found in many competitors, putting it closer to hospital-grade air purification.

CADR & Sound

Noise & Performance

With a dust CADR of 406 CFM, the MA-40 can process the air in a 1,793 sq ft space in about one hour , placing it in the top tier for coverage among consumer purifiers. Noise ranges from 46 dB on the lowest setting to 66 dB at maximum speed; the low setting is comparable to a quiet library with some ambient hum, while max speed sounds like a normal conversation.

For bedroom use, the dedicated sleep mode dims the display and reduces fan speed, though sensitive sleepers may still notice the baseline noise.

Connectivity

Smart Features & Controls

The touch-panel controls offer three fan speeds, auto mode, sleep mode, and a programmable timer, all paired with a built-in air quality indicator that provides real-time feedback. Auto mode is the standout feature , it reads ambient air quality and adjusts fan speed accordingly, eliminating the need for constant manual adjustments.

However, there is no WiFi connectivity or smartphone app, so all control must happen at the unit itself, and there is no integration with Alexa, Google Home, or other smart home platforms.

Upkeep

Filter Maintenance

Replacement filters (model B07MTQFFNT) have a six-month lifespan under normal use, and the built-in filter change indicator alerts you when it is time for a swap. The pre-filter captures larger debris to extend the life of the HEPA and carbon stages.

Maintenance is straightforward , no tools are required for filter replacement, and the pre-filter can be vacuumed periodically to maintain optimal airflow between full filter changes.

Who Is This Air Purifier For?

Ideal For

  • Allergy and asthma sufferers , H13 HEPA filtration captures 99.95%+ of allergens including pollen, dust mites, and pet dander down to 0.1 microns
  • Pet owners in large homes , carbon filter neutralizes pet odors while the HEPA filter traps dander and fine pet hair across 1,793 sq ft

  • Wildfire smoke and odor management , three-stage filtration with activated carbon absorbs smoke particles, cooking smells, and VOCs

Not Ideal For

  • Smart home enthusiasts , no WiFi, app control, or voice assistant integration means you must adjust settings manually at the unit
  • Light sleepers in very quiet rooms , the 46 dB minimum noise floor is louder than many competitors' sleep modes, which often sit below 30 dB
  • Small apartment dwellers looking for an entry-level option , the 2-pack is designed for large spaces, and a single smaller unit would be more well-equipped for studios or one-bedroom apartments

FAQ

How often do I need to replace the HEPA filter in the Medify MA-40?

The replacement filter (model B07MTQFFNT) lasts approximately six months under normal use. The MA-40 has a built-in filter change indicator that alerts you when the filter needs replacing.

In homes with heavy pet dander, smoke, or high dust levels, you may need to replace it slightly sooner.

Is the Medify MA-40 quiet enough for a bedroom?

The MA-40 includes a dedicated sleep mode that reduces fan speed and dims display lights. However, the minimum noise level is 46 dB, which is audible in very quiet bedrooms.

On medium and high settings, noise increases up to 66 dB. Light sleepers may want to test the sleep mode before committing to overnight use.

Can the Medify MA-40 actually cover 1,793 sq ft?

Yes, each unit delivers a dust CADR of 406 CFM, which is sufficient to cycle the air in a 1,793 sq ft space roughly once per hour. For faster air changes or heavily polluted spaces, using the 2-pack across separate rooms or zones in your home will provide more effective coverage than relying on a single unit for the entire area.

Does the Medify MA-40 work with Alexa or Google Home?

No, the MA-40 does not have WiFi connectivity or app control, so it cannot integrate with Alexa, Google Home, or other smart home systems. All adjustments must be made via the touch controls on the unit itself.

If smart home integration is a priority, you would need to look at purifiers from brands that offer app-connected models.

Does the Medify MA-40 remove smoke and wildfire odors?

The three-stage filtration system is effective against smoke. The H13 HEPA filter captures fine smoke particles down to 0.1 microns, while the activated carbon filter absorbs smoke odors, VOCs, and other gases.

With a CADR of 406 CFM, it can clear smoke from large living rooms and open-plan spaces relatively quickly.

Is the Medify MA-40 good for pet owners with allergies?

The MA-40 is an excellent choice for pet owners. The pre-filter traps pet hair and larger debris, the H13 HEPA filter captures 99.95% of pet dander particles, and the activated carbon filter neutralizes pet odors.

The 1,793 sq ft coverage means it can handle homes and apartments where pets roam freely across multiple rooms.
