Choosing an air purifier gets confusing when a large room-coverage number does not tell you how often the air is actually cleaned. The Medify MA-25 Air Purifier is a compact, three-speed model with HEPA H13 filtration, an active-carbon stage, and enough airflow for bedrooms, offices, and other small to medium spaces. Its strongest points are quiet low-speed operation, simple controls, and verified CADR performance, while its main tradeoffs are frequent filter replacement and the lack of app-based smart controls. This review explains the numbers so you can decide whether the MA-25 fits your room and daily needs.
Quick Verdict
Rating: 8.5/10, Recommended with caveats
Best For: Bedrooms, home offices, nurseries, and small to medium rooms where you want quiet mechanical filtration.
Bottom Line: The MA-25 combines a compact 7.3-pound body with three-stage filtration, verified CADR figures, and operation as low as 19.8 dBA. The main compromise is that its 825-square-foot claim represents only one air change per hour, so smaller rooms make better use of its airflow when faster cleaning is important.

What Is the Medify MA-25 Air Purifier?
The Medify MA-25 is a compact portable purifier designed to filter airborne particles in a single room or defined indoor area. It uses a pre-filter for larger material, HEPA H13 filtration for fine particles, and an active-carbon composite layer that helps with odors and smoke-related contaminants.
Its 8-by-8-inch footprint makes it easier to place on the floor or another appropriate stable surface without taking up the space of a larger console purifier. At 7.3 pounds, you can also move it between a bedroom and home office more easily than many higher-output models.
The MA-25 is not a smart purifier. Its current control set centers on the touch panel, timer, child lock, filter indicator, dimmer, and three manual fan speeds. That simplicity can be useful if you prefer direct controls, but buyers who want app monitoring, automatic particle sensing, or remote control should compare other models.
Who Should Buy It?
Best For
- You want a quiet purifier for a bedroom, nursery, or home office.
- You prefer simple touch controls instead of an app-dependent setup.
- You need HEPA particle filtration plus an active-carbon stage for everyday dust, pollen, dander, smoke particles, and odors.
Skip If
- You need several air changes per hour in a very large room.
- You want Wi-Fi, app controls, or an automatic air-quality sensor.
- You want long filter intervals with less frequent replacement expense.
Before You Buy: Do not judge the MA-25 only by the 825-square-foot headline. That figure represents about one air change per hour. If you want roughly four to five air changes per hour, its verified coverage is closer to 165-206 square feet.
Key Takeaways
- The MA-25 uses a pre-filter, HEPA H13 filtration, and an active-carbon composite stage.
- Its manufacturer-listed maximum coverage is 825 square feet at one air change per hour.
- For faster circulation, the same purifier covers about 206 square feet at four air changes per hour.
- Noise ranges from 19.8 dBA on speed 1 to 49.3 dBA on speed 3.
- The compact body measures 13.5 × 8 × 8 inches and weighs 7.3 pounds.
- Rated power is 28W, and the model is ENERGY STAR certified.
- Filters are rated for about 2,500 hours or roughly 3-4 months of continuous operation.
Filtration and Air-Cleaning Performance
The HEPA H13 filter is the main reason to consider the MA-25. Medify states that the filter material is tested to remove 99.9% of particles down to 0.1 microns. In practical terms, the purifier is designed to capture airborne material such as dust, pollen, pet dander, and fine smoke particles as room air repeatedly passes through the unit.
The active-carbon composite adds an odor-control stage. This can make the MA-25 more useful around cooking odors, pet smells, or smoke than a particle-only purifier. Carbon filtration has limits, however, and no portable purifier should be treated as a complete solution for every gas, odor, or pollution source.
The MA-25’s CADR numbers provide a better performance reference than the largest room-size claim. Medify lists 110 CFM for smoke, 123 CFM for dust and pollen, and 116 CFM for PM2.5. Those figures make it most convincing in small and medium rooms where the purifier can cycle the air several times each hour.
Design, Size, and Controls
The MA-25 has a narrow 8-by-8-inch footprint and a 13.5-inch height. Its compact shape makes placement easier in bedrooms and offices where floor space matters. Medify also uses a tempered-glass touchscreen-style control surface, giving the unit a cleaner appearance than purifiers with large mechanical switches.
You get three fan speeds, preset timer controls, a filter replacement indicator, child lock, and dimmer. These cover the basics well. What you do not get is built-in network capability, so you should not buy it expecting phone notifications, app scheduling, or remote air-quality monitoring.
Medify MA-25 Noise Levels: What to Expect
Noise is one of the MA-25’s better features. Speed 1 is rated at 19.8 dBA, speed 2 at 37 dBA, and speed 3 at 49.3 dBA. The lowest setting is therefore much more suitable for sleeping, reading, or desk work than the highest setting.
Higher fan speed moves more air, so there is a normal tradeoff between sound and cleaning rate. You can use a higher setting after cooking, cleaning, opening windows during high-pollen conditions, or when airborne particles have increased, then lower the fan once the room has had time to cycle.
How It Performs in Real Use
For Bedroom Use
The combination of a 19.8 dBA low setting and dimmable panel makes the MA-25 well suited to a bedroom. Its small footprint also makes placement easier than with a larger high-CADR purifier. For a bedroom around the 165-206-square-foot range, the purifier can deliver several air changes per hour rather than relying on the slower 825-square-foot rating.
For a Home Office
In a home office, the low and middle speeds give you a useful balance between air movement and noise. The touch controls make quick adjustments simple, and the 7.3-pound weight is practical if you move the purifier between work and sleeping areas.
For a Medium Living Area
The MA-25 can serve a larger living space, but cleaning frequency drops as the room gets bigger. At 413 square feet, the manufacturer rates it for about two air changes per hour. At the full 825-square-foot figure, it is rated for about one complete air change per hour, so a larger or higher-CADR purifier may make more sense when rapid cleaning is the priority.
For Smoke, Cooking, and Odor Events
The HEPA stage can capture airborne smoke particles while the active-carbon stage helps with odors. For an active smoke source or significant indoor pollution, however, use the purifier as a supplement to source control and appropriate ventilation rather than expecting filtration alone to remove every pollutant.
Setup Tips for Better Results
- Place the purifier where its air intakes and outlet are not blocked by curtains, furniture, walls, or clutter.
- Match fan speed to the situation. Higher speed provides more airflow, while lower speed is better when quiet operation matters.
- For a larger room, remember that the purifier needs more time to cycle the same volume of air.
- Check the filter indicator instead of relying only on the calendar.
- Follow Medify’s operating and filter-installation instructions whenever you replace or clean the filter assembly.
Pro Tip: If you are choosing between room-size ratings, use the rating with the higher ACH whenever faster particle removal matters. For the MA-25, a 165-206-square-foot room gives you much more frequent air cycling than an 825-square-foot space.
Safety and Air-Quality Notes
The MA-25 is a fan-and-filter air cleaner rather than a medical treatment. ENERGY STAR’s certified-product record lists the model with HEPA and activated-carbon filtration and reports 0.0 ppb ozone emissions under its certification data.
Even effective filtration cannot eliminate every indoor pollutant. If you are dealing with smoke, mold, strong chemical fumes, or another ongoing pollution source, address the source itself and use appropriate ventilation when conditions allow. Follow the purifier manual and professional guidance when an indoor-air problem involves health or building-safety concerns.
Filter Maintenance and Replacement Tips
Medify rates the MA-25 filter for about 2,500 operating hours, which it describes as roughly 3-4 months of continuous use. Your actual schedule can vary with fan speed, operating time, dust load, pets, smoke, and other indoor conditions, so the filter indicator is a useful reminder.
For routine maintenance, Medify advises vacuuming the pre-filter about once a month under normal use. Unplug the purifier first, remove the filter as directed, and use a vacuum brush attachment on the appropriate pre-filter surface. The filter should be reinstalled correctly before you reconnect power.
After replacing the filter, Medify’s support guidance instructs users to hold the DIMMER control for three seconds to reset the filter indicator. Using the correct replacement filter also matters because the limited lifetime warranty has conditions tied to registration, operation, and Medify’s warranty requirements.
Pros and Cons
Pros
- HEPA H13 filtration plus an active-carbon stage for particles and odors.
- Compact 13.5 × 8 × 8-inch body weighs only 7.3 pounds.
- Very quiet 19.8 dBA operation on the lowest fan speed.
- ENERGY STAR certified with a manufacturer-listed 28W power rating.
- Useful touch controls with timer, child lock, dimmer, and filter indicator.

- No app connectivity or network-based smart controls are listed.
Is It Worth the Price?
The Medify MA-25 sits in the mid-range part of the compact air-purifier market. Its value comes from verified airflow data, HEPA H13 filtration, quiet operation, modest 28W rated power, a small footprint, and a limited lifetime warranty rather than from smart-home features.
It makes the most sense if you want a straightforward purifier for a bedroom, office, or similar room and are comfortable replacing filters every few months of continuous use. It is less compelling if you want app controls, automatic air-quality adjustment, or enough airflow to produce several air changes per hour in a large open-plan room.
How It Compares to Alternatives
If smart controls matter, the Levoit Core 300S is worth comparing because it adds connected features while targeting a similar compact-purifier buyer. The Blueair Blue Pure 511i Max is another smart option with app-based controls, automatic operation, and higher listed smoke CADR.
If you care more about airflow than compact size, the Coway Airmega Mighty AP-1512HH offers substantially higher CADR and automatic/Eco operation, although it is larger and has a higher rated power draw. The MA-25 makes the most sense when you prioritize a narrower footprint, quiet low-speed use, and simple controls.
Frequently Asked Questions
How large a room can the Medify MA-25 handle?
Medify lists up to 825 square feet in 60 minutes, which equals about one air change per hour. For faster cleaning, it is rated for about 413 square feet at two ACH, 206 square feet at four ACH, or 165 square feet at five ACH.
How often should you replace the MA-25 filter?
Medify rates the filter for about 2,500 operating hours, or roughly 3-4 months of continuous use. Actual life can vary with your operating time and indoor particle load, so use the filter indicator as an additional guide.
Can you clean the MA-25 pre-filter?
Medify recommends vacuuming the pre-filter about once a month under normal conditions. Unplug the purifier first and follow the manufacturer’s filter-removal instructions before cleaning it with a vacuum brush attachment.
Can the Medify MA-25 help with cigarette or wildfire smoke?
Its HEPA stage is designed to capture airborne smoke particles, while the carbon stage can help reduce some smoke-related odors. It cannot remove every pollutant or replace eliminating the smoke source and using appropriate ventilation.
Is the Medify MA-25 useful in homes with pets?
The pre-filter and HEPA stage can capture airborne material such as hair-related debris and pet dander that reaches the purifier. The carbon stage can also help with some odors, but you will still need normal cleaning and source control around litter, bedding, and pet areas.
Does the MA-25 have Wi-Fi or app controls?
No network capability is listed for the MA-25. Its controls are handled through the unit’s touch panel, including fan speed, timer, child lock, dimmer, and filter indicator.
Is the Medify MA-25 quiet enough for sleeping?
Its lowest fan speed is rated at 19.8 dBA, making it well suited to quiet rooms. The highest setting reaches 49.3 dBA, so you may prefer running a faster speed before bedtime and lowering it when you sleep.
Does the Medify MA-25 have a lifetime warranty?
Medify describes the coverage as a limited lifetime warranty. Registration and compliance with the company’s warranty and operating requirements are important, so review the current warranty terms rather than assuming every failure is automatically covered.
The Bottom Line
The Medify MA-25 is a strong choice if you want a compact, quiet HEPA air purifier for a bedroom, office, or other small to medium room. Its biggest strengths are verified particle-filtration performance, low 19.8 dBA operation, straightforward controls, and a small 7.3-pound body, while its main limitations are frequent filter replacement and slower air turnover when used near the full 825-square-foot coverage claim.
If you need smart controls or high air-change rates in a large open room, compare a larger or connected purifier instead. For straightforward everyday filtration in a more appropriately sized room, the MA-25 earns its recommended-with-caveats verdict.
