If you searched for a modify air purifier, you were most likely looking for Medify, a brand that builds HEPA H13 air purifiers in sizes ranging from small tabletop units to machines rated for thousands of square feet. Medify’s lineup is organized mostly by room coverage, which makes it easier to match a model to a bedroom, dorm or whole apartment than with brands that blur the lines.
The five models here cover roughly 470 to 4,455 square feet per hour, so the main differences are coverage, noise at full speed, and the extra features larger units add, such as auto mode and a PM2.5 indicator on the MA-112.

The Medify MA-40 Air Purifier with HEPA is Medify’s mid-to-large option. It cleans up to 1,793 square feet in one hour, or 896 square feet in 30 minutes, with a CADR of 406. The HEPA H13 filter is described as removing 99.9% of particles including allergens, odors, VOCs, smoke, pollen and pet dander, down to 0.1 microns. The listing title references 0.3 microns while the features say 0.1, so the exact figure depends on which test you read.
It has three fan speeds, running from 46 dB at the lowest setting to 66 dB at the highest, and a sleep mode that dims the panel lights completely. The touch screen includes a 0 to 8 hour timer, a filter replacement indicator and a child lock. The medify ma-40 draws 95 watts, is CARB and ETL listed, and carries a registered lifetime warranty. Its replacement filter lasts about 3,000 hours, or roughly six months.
This is the model for a living room, open-plan apartment or office where you want serious coverage without stepping up to the largest units. It is too big to take on a trip; for a bedroom or rental stay, the MA-25 or MA-14 is a better fit.

Its standout feature is noise: three fan speeds run from 19.8 dB to 49.3 dB, the quietest range in this group, although the specifications separately list 51 dB. It draws only 28 watts. The touch panel includes a 0 to 8 hour timer, sleep mode, a filter replacement indicator and a child lock. The replacement filter lasts about 2,500 hours, or three to four months. The listing does not give a CADR.
The medify ma-25 is the pick for bedrooms, dorm rooms, nurseries and short-term rentals where quiet sleep matters most. It is small enough to move from room to room, and it gives way to the MA-40 only when you need to clean a larger open space.

Pros
- Smallest tabletop unit
- CADR 120
- Night light and sleep mode
- 360-degree filter
Cons
- 470 sq ft per hour only
- No timer or child lock listed
The Medify MA-14 Air Purifier with HEPA is the smallest model in this roundup. It cleans up to 470 square feet in one hour with a CADR of 120, which suits a small bedroom, nursery or home office. It uses True HEPA H13 filtration with a 360-degree high-efficiency filter, and Medify says it removes 99.9% of particles down to 0.1 microns.
Three fan speeds top out at 55 dB, while the specifications list 44.6 dB. The control panel has fan speed, a night light, sleep mode and a filter replacement indicator. Unlike the MA-25, the listing does not mention a timer or child lock. The replacement filter lasts about 2,500 hours, and the unit is CARB and ETL listed with a lifetime warranty. The specifications list 95 watts and a floor area of 4,455, both of which look copied from a larger model, so rely on the feature text instead.
The medify ma-14 suits anyone who needs a compact purifier for a single small room. The MA-25 covers nearly twice the area and runs quieter at the low end, so it is worth the step up if you need a timer or child lock.

The replacement filter lasts about 2,500 hours, or three to four months, which is shorter than the MA-40’s.

Medify MA-112 Air Purifier V3.0 for Whole Floors
4.1 Amazon buyer average
Best for: Whole floors and open offices
What the listing says
- MAXIMUM COVERAGE Cleans large spaces up to 4,455 sq ft in one hour, 2,228 sq ft in 30 minutes (CADR 1009).
- DUAL HEPA H13 FILTRATION Trusted to remove 99.9% of harmful particles including allergens, odors, VOCs, smoke, pollen, pet dander, dust,…

Pros
- CADR 1009
- Dual HEPA H13 filters
- Auto mode and PM2.5 indicator
- Dust sensor
Cons
- Up to 70 dB
- Coverage figures conflict
The Medify MA-112 Air Purifier V3.0 is the largest model here, with a CADR of 1009. The feature text says it cleans up to 4,455 square feet in one hour and 2,228 in 30 minutes, while the title claims 5,948 square feet. We use the feature figure, but the discrepancy is worth noting.
It uses dual HEPA H13 filters and lists activated carbon in its filter class. The touch panel adds features the smaller models lack: an optional ionizer, a dust sensor, auto mode and a PM2.5 pollution indicator, along with a 0 to 8 hour timer, sleep mode, filter indicator and child lock. It has four fan speeds with a maximum of 70 dB, the loudest here. The replacement filter lasts about 3,000 hours.
The medify ma-112 suits large open homes, offices and classrooms. It is not portable and will be loud at full speed, so pick it only when the space truly demands the coverage.
Before you choose
How to Choose the Right Medify Air Purifier
Start with room size. Measure the square footage and pick a model whose one-hour coverage comfortably exceeds it: the MA-14 for small bedrooms, the MA-25 for bedrooms and dorms, the MA-40 for living rooms, the MA-50 for large open spaces and the MA-112 for whole floors.
Next, consider noise. The MA-25 has the lowest listed range, starting at 19.8 dB, while the MA-112 reaches 70 dB at full speed. For sleep, lower is better.
Filter life affects maintenance. The MA-40 and MA-112 filters last about six months, while the MA-25, MA-14 and MA-50 filters last three to four months.
Finally, features. Only the MA-112 lists auto mode, a dust sensor and a PM2.5 indicator. If you want a smart purifier that adjusts on its own, that is the one. For comparable options in the middle of the range, see our guide to a medium room air purifier.
