Filtration Technology
The Medify MA-40 uses a True HEPA H13 filter rated to capture 99.95% of particles at 0.3 microns and effective down to 0.1 microns , the same medical-grade classification used in hospital environments. The H13 HEPA filter handles fine particulates including wildfire smoke, pollen, dust mites, and pet dander.
While it excels at particle filtration, buyers who need heavy-duty odor or VOC removal should note the absence of a dedicated activated carbon stage.
Noise & Performance
With a CADR of 406, each MA-40 purifies 1,793 sq ft of space in one hour , placing it among the highest-coverage purifiers available and well above the median of 500 sq ft. Noise ranges from 46 dB on the lowest setting (comparable to a quiet library) to 66 dB at max speed (normal conversation level). The sleep mode drops noise further, making it workable for bedrooms, though the 46 dB minimum is slightly above whisper-quiet competitors.
Smart Features & Controls
Controls are handled via a touch panel on the unit itself, offering three fan speeds, a sleep mode, a timer, and a child lock , no WiFi, app, or voice control is included. The absence of auto mode means there is no built-in air quality sensor to dynamically adjust fan speed, so you will need to manually select settings based on conditions.
What it lacks in smart connectivity it makes up for in simplicity , setup is immediate with no accounts or pairing required.
Filter Maintenance
The MA-40 uses a dedicated MA-40 True HEPA H13 replacement filter and includes a filter change indicator light that alerts you when it is time to swap. Medify generally recommends filter replacement every 2,500 hours of use, which works out to roughly 3-4 months of continuous operation or 6-8 months of moderate daily use.
Maintenance is straightforward , remove the back panel, pull the old filter, and slide in the new one.
Who Is This Air Purifier For?
Ideal For
- ✓ Homeowners with large open-plan spaces , each unit's 1,793 sq ft coverage and CADR 406 handles great rooms, lofts, and combined living areas with ease
- ✓ Allergy and asthma sufferers , H13 HEPA filtration captures 99.95%+ of pollen, dust mites, mold spores, and fine particulates down to 0.1 microns
- ✓ Pet owners in large homes , True HEPA captures pet dander and fine hair particles across wide coverage areas, and the 2-pack lets you cover multiple floors
- ✓ Wildfire smoke season preppers , high CADR and medical-grade HEPA filtration make these effective at clearing smoke particulates from large indoor spaces
Not Ideal For
- ✕ Smart home enthusiasts , no WiFi, no app, no voice assistant integration means this won't fit into automated routines
- ✕ Users who need strong odor and VOC removal , without a dedicated activated carbon filter stage, gas-phase pollutants and persistent cooking or smoke odors won't be fully addressed
- ✕ Noise-sensitive bedroom users on high speed , at 66 dB max the unit is audible, though sleep mode mitigates this at lower fan speeds
Setup is nearly instant , remove the unit from packaging, take the HEPA filter out of its sealed plastic wrap, insert it into the back panel compartment, and power on. At 9.2 lbs per unit and compact 10.5 x 11 x 22-inch dimensions, placement is flexible even on countertops or side tables.
Remember to remove the plastic wrap from the filter before first use , a common oversight that prevents airflow
Position each unit with at least 12 inches of clearance on all sides for optimal air intake and circulation
Medify Air typically offers a limited warranty on their purifiers, though specific coverage terms and duration should be verified directly with the manufacturer or your point of purchase. Medify is a US-based brand with customer support available for filter replacements and troubleshooting.
FAQ
How large of a room can the Medify MA-40 actually cover?
Each MA-40 unit covers up to 1,793 sq ft in one hour with a CADR of 406, making it one of the highest-coverage purifiers in its class. For spaces like large living rooms, open-concept apartments, or combined kitchen-dining areas, a single unit is sufficient.
The 2-pack lets you cover two floors or separate wings of larger homes.
Is the Medify MA-40 quiet enough to use in a bedroom at night?
On sleep mode, the MA-40 reduces fan noise and dims the display for nighttime use. The minimum noise level is 46 dB, which is roughly equivalent to a quiet library.
Does the Medify MA-40 remove smoke and odors from wildfires?
The H13 HEPA filter is highly effective at capturing fine wildfire smoke particulates down to 0.1 microns. However, for gaseous odors and VOCs that accompany smoke, performance is more limited since there is no dedicated activated carbon filter stage.
It will significantly reduce visible smoke haze and particulate matter but may not fully eliminate lingering smoke smell.
How often do I need to replace the filters on the Medify MA-40?
Medify recommends replacing the MA-40 True HEPA H13 filter approximately every 2,500 hours of use. With daily operation of 8-12 hours, that translates to roughly every 6-8 months.
The built-in filter change indicator light will alert you when replacement is needed, taking the guesswork out of maintenance.
Can I control the Medify MA-40 with Alexa, Google Home, or a phone app?
No , the MA-40 does not include WiFi, app connectivity, or voice assistant integration. All controls are managed via the touch panel directly on the unit.
If smart home integration is a priority, you would need to look at WiFi-enabled alternatives, though you can use a smart plug for basic on/off scheduling.
How much does it cost to run two Medify MA-40 units continuously?
Each unit draws just 68W and is Energy Star certified. Running two units 24/7 at maximum power costs approximately -16 per month depending on your local electricity rate.
On lower speeds and sleep mode, actual consumption is considerably less, making the 2-pack an energy-efficient whole-house solution for large homes and apartments.
