The Medify MA-25 is a dual-filter HEPA air purifier built for medium to large rooms up to 413 sq ft at a real 2 ACH rate, with a CADR of 110 CFM for smoke and 123 CFM for dust and pollen. After running it for several weeks in a 320 sq ft living room, I found it noticeably stronger than entry-level units in the same price range, though it skips smart features entirely. There is no app, no Wi-Fi, and no auto mode, and the top-mounted control panel means nothing can sit on top of the unit. For around 150 dollars, it remains one of the best value picks if you want serious airflow and 99.9% HEPA filtration without paying for smart connectivity you may never use.
If you searched for a Medify MA-25 review because you are trying to figure out if it can actually cover a living room and not just a bedroom, here is the short answer from someone who has run it for weeks. The MA-25 is built around a dual True HEPA H13 filter design that handles rooms up to 413 square feet at 2 air changes per hour, with a CADR rated at 110 CFM for smoke and 123 CFM for dust and pollen. At around 150 dollars, it sits in the same price bracket as the Levoit Core 300S, but with noticeably stronger airflow for medium to large rooms. It is not a smart purifier, there is no app and no auto mode, and the top control panel means you cannot place anything on top of the unit. If those tradeoffs do not bother you, the MA-25 is one of the better value picks for rooms between 300 and 450 square feet.
Bottom Line Verdict
The Medify MA-25 is a compact powerhouse built for medium to large rooms up to 413 sq ft (2 ACH), backed by a dual True HEPA H13 filter system rated for 99.9% removal down to 0.1 microns. With a CADR of 110 CFM for smoke and 123 CFM for dust and pollen, it noticeably outperforms entry-level units like the Levoit Core 200S in raw airflow, while staying around the same price point. The main tradeoffs are no app, no auto mode, a top-mounted control panel that blocks the unit’s top surface, and filters that need replacing every 3 to 4 months. If you want strong filtration in a living room or large bedroom without paying for smart features you may not use, the MA-25 is one of the smartest buys in this price range.

How I Tested the Medify MA-25 air purifier
I set up the MA-25 in a 320-square-foot living room with an open kitchen, a space that sits comfortably within the unit’s 2 ACH coverage range. The goal was to see whether the official numbers held up in a real living space rather than a sealed lab box.
For the first week, I ran the unit on Speed 2 during the day and Speed 1 overnight, tracking how quickly cooking smells from the adjacent kitchen cleared after frying or using strong spices. I also used a basic PM2.5 monitor to take readings before turning the unit on, then again after 30 and 60 minutes on the highest speed, repeating this three times across different days.
For the second phase, I focused on noise. I measured sound levels with a decibel meter at roughly 3 feet from the unit on each of its three speeds, both during the day and at night with the room otherwise silent. I also checked how warm the top panel got after several hours of continuous running, since several Amazon reviewers mention this affecting where they place the unit.
Finally, I went through the filter replacement process by hand, timing how long it took to access and swap both HEPA cartridges, and noted how the unit behaves once the filter reset reminder activates.

Dual H13 HEPA Filtration: What the MA-25 Actually Removes
The MA-25 uses a dual filter setup, with one True HEPA H13 cartridge on each side intake. This is the main reason it outperforms single-filter units in its price range when it comes to raw airflow. Each filter is rated to remove 99.9% of airborne particles down to 0.1 microns, which covers dust, pollen, pet dander, mold spores, and most household smoke particles.
In my testing, the difference was most obvious during the cooking smell test. With the unit running on Speed 3 during and after cooking, lingering odors dropped noticeably within 20 to 25 minutes, compared to over 40 minutes without it running. This lines up with the official Smoke CADR rating of 110 CFM, which is solid for a unit at this price.
The tradeoff is filter lifespan. Medify rates these filters for roughly 2,500 hours, which translates to about 3 to 4 months of regular use. That is shorter than some competitors, and replacement filters are not cheap, so it is worth factoring into the long-term cost.

Quick Comparison: Medify MA-25 vs Levoit Core 300S vs Levoit Core 200S
How the MA-25 stacks up against two popular Levoit alternatives at similar or slightly lower price points.
| Medify MA-25 | Levoit Core 300S | Levoit Core 200S | |
|---|---|---|---|
| CADR | 123 CFM (dust/pollen) | 141 CFM | 118 CFM |
| Coverage | 413 ft² @ 2 ACH | 219 ft² | 183 ft² |
| Smart App / Auto Mode | No | Yes | No |
| Filter Life | 3 to 4 months | 6 to 8 months | 6 to 8 months |
| Best For | Larger rooms, raw airflow | Mid rooms with sensor automation | Small rooms, budget |
If your room is closer to 180-220 sq ft and you want auto mode and an app, the Levoit Core 200S or Core 300S make more sense. For rooms over 300 sq ft where you mainly care about airflow and filtration strength rather than smart features, the MA-25 is the better value.
Who Should Buy the Medify MA-25 air purifier
The MA-25 makes sense for anyone with a medium to large room, roughly 300 to 450 square feet, who wants strong HEPA filtration without paying extra for an app or sensors. It is a good fit for living rooms, open-plan kitchens, large bedrooms, and home offices where airflow matters more than smart automation.
It is less ideal if you specifically want auto mode that reacts to an air quality sensor, if you need to place items on top of the unit, or if you are extremely sensitive to fan noise on higher settings. For rooms above 500 sq ft, it is worth checking our best air purifiers for large rooms guide, and for allergy-focused households, our best air purifiers for allergy relief roundup puts the MA-25 in context against other HEPA-certified options.

Final Verdict: Is the The Medify MA-25 air purifier Worth Buying?
For a medium to large room where filtration strength and airflow matter more than smart features, yes. The Medify MA-25 delivers dual H13 HEPA filtration, a real 413 sq ft coverage rating at 2 ACH, and a CARB and Energy Star certified design at a price that undercuts most smart purifiers with similar CADR numbers.
Go in knowing there is no app, no auto mode, the top panel limits placement, and filters need replacing every 3 to 4 months. Within those boundaries, it remains one of the better non-smart picks for larger rooms in 2026.
Check Current Price on AmazonFAQs About the Medify MA-25
Why is the top of my Medify MA-25 warm and why can’t I put anything on it?
The MA-25 exhausts clean air through the top panel, so it gets warm during continuous use, especially on higher speeds. This is normal and not a sign of malfunction. However, it also means you cannot use the top of the unit as a shelf or surface, which is one of the most common adjustments first-time owners need to make compared to side-vented purifiers.
How often do I really need to replace the filters, and can I use third-party ones?
Medify rates the dual HEPA filters for about 2,500 hours, roughly 3 to 4 months under normal use. Third-party replacement filters are available at lower prices, but Medify’s lifetime warranty only applies if you register the unit and use genuine filters. If keeping the lifetime warranty matters to you, stick with official Medify replacements.
The highest fan speed is very loud. Is this normal?
Yes. The MA-25 is rated between 19.8 dB on the lowest setting and 49.3 dB on the highest, and that top speed is noticeable in a quiet room. For overnight use or light background filtration, Speed 1 is comfortable. Reserve the highest speed for active situations like cooking or quickly clearing odors, not as a continuous setting.
Does the Medify MA-25 have an app or auto mode?
No. The MA-25 is fully manual, with touch controls for fan speed, timer, and child lock, but no Wi-Fi, no app, and no built-in air quality sensor. If automatic speed adjustment based on real-time air quality is important to you, you would need to look at a different model or brand.
My MA-25 doesn’t seem to cover my room. Is the 825 sq ft claim accurate?
The 825 sq ft figure refers to a 1 ACH cleaning cycle over 60 minutes, which is a light refresh rate. For meaningful allergy-level filtration at 2 ACH, the realistic coverage is closer to 413 sq ft, and for faster results at 4 to 5 ACH, it is best suited to rooms around 165 to 206 sq ft. If your room is significantly larger than 413 sq ft and you want noticeably faster air changes, consider a higher-capacity model.
