Filtration Technology
The MA-45 uses a medical-grade H13 HEPA filter that captures 99.95% of airborne particles at 0.3 microns and cleans down to 0.1 microns, covering pollen, dust mites, pet dander, mold spores, and fine particulate matter. The built-in UV-C light adds a secondary layer by targeting airborne bacteria and viruses as air passes through the unit.
This dual-stage approach puts it ahead of purifiers that rely on standard HEPA alone, though it lacks a dedicated activated carbon stage for gas-phase pollutants.
Noise & Performance
With a dust CADR of 350 CFM, the MA-45 cleans its full 1,544 sq ft coverage area in about one hour , significantly faster than most competitors in this category. At max speed the unit produces 66 dB, roughly the volume of a normal conversation, which is typical for a purifier pushing this much air.
Sleep mode drops noise and dims the display for bedroom use, making it workable for overnight operation in bedrooms and offices at lower speeds.
Smart Features & Controls
Controls are handled via a touch panel on the unit with 4 fan speeds, a dedicated sleep mode, and a built-in timer for scheduled operation. There's no WiFi connectivity, app control, or voice assistant integration, so all adjustments are manual.
The absence of an auto mode with air quality sensing is the biggest gap , you won't get hands-free speed adjustments based on real-time air conditions, which is a feature found on many competing models in this tier.
Filter Maintenance
Medify rates the filter life at approximately 4 months under normal use, though heavy-use environments like homes with multiple pets or during wildfire season may shorten this. The unit includes a filter change indicator to take the guesswork out of replacement timing.
Replacement filters are readily available through Medify's website and major retailers , look for the MA-45 replacement filter to ensure compatibility.

FAQ
How large of a room can the Medify MA-45 actually clean?
The MA-45 covers up to 1,544 sq ft in one hour with its CADR of 350 CFM. This makes it effective for large living rooms, open-concept apartments, and even whole-home use in smaller homes.
For faster air changes in bedrooms or offices, using it in spaces under 800 sq ft will cycle the air roughly twice per hour.
Is the Medify MA-45 good for allergies and pet dander?
Yes , the H13 HEPA filter captures 99.95% of particles at 0.3 microns, including pollen, dust mites, pet dander, and mold spores. The UV-C light adds an extra layer against airborne microorganisms.
For homes with pets, the 1,544 sq ft coverage means it can handle dander circulation across large spaces effectively.
How loud is the Medify MA-45 air purifier?
At maximum speed the MA-45 produces 66 dB, which is about the volume of a normal conversation. Sleep mode significantly reduces noise output and dims the display, making it suitable for bedrooms and offices at lower speeds.
Most users will find speeds 1-2 quiet enough for sleeping.
Does the Medify MA-45 remove smoke and odors?
The H13 HEPA filter is effective at capturing smoke particulates, which is why Medify markets it for wildfire smoke. However, it does not have a dedicated activated carbon filter, so gas-phase odors like cooking smells or VOCs won't be fully eliminated.
For heavy odor removal, consider a purifier with a substantial carbon filter stage.
How often do you need to replace the filter on the MA-45?
Medify recommends replacing the filter every 4 months under typical use. The unit has a built-in filter change indicator that alerts you when it's time.
In high-pollution environments or homes with multiple pets, you may need to replace it more frequently , roughly every 2-3 months.
Can you control the Medify MA-45 with a phone app or Alexa?
No , the MA-45 does not have WiFi connectivity, app control, or voice assistant integration. All controls are managed through the touch panel on the unit, which includes 4 speed settings, sleep mode, and a timer.
If smart home integration is a priority, you'll need to look at WiFi-enabled models from other brands.
