Medify Air MA-15 Dual True HEPA Air Purifier – Review

In this review, I will test and evaluate the Medify Air MA-15 air purifier. Medify Air is a brand that makes air purifiers of various sizes for multiple purposes and for rooms of different sizes.

So far, I have not tested any air purifiers from this brand. I opted for the MA-15 model because it seems like a perfect option and a competitor to many air purifiers designed for rooms of similar dimensions. Medify Air MA-15 is designed for rooms up to 330 sq. ft.

Medify Air MA-15 - Air Purifier Review

Medify MA-15 uses 2 identical filters, which are placed on the sides. The MA-14 model is similar to the MA-15, but at first sight, you can see that the MA-15 is more advanced considering the airflow and obviously overall performance. Because of the specifications, I decided to review the successor and the somewhat more powerful MA-15 model.

How good it really is, how much it helps to use two filters, and whether it can handle everyday conditions, I will write in the review below.

Short on time? Here are highlights of the Medify MA-15

  • Medify MA-15 is designed for rooms up to 330 sq. ft.
  • The MA-15 uses a dual True HEPA filter, which is most deserving of good performance.
  • This is a small, portable air purifier, which is currently available in silver and white color.
  • The MA-15 has minimal energy consumption; the engine power is only 25W.
  • It is entirely safe to use, and does not produce ozone.
  • Medify Air offers a Lifetime Warranty for the MA-15 air purifier if you commit to regular filter replacement.

Design

Medify MA-15 is a small, compact air purifier, rectangular in shape.

It is available in silver and white color. For this review, I bought a device in silver because it is unusual, unusual, and in my opinion, more beautiful than the model in white color.

Medify Air MA-15 Air Purifier - Positioned on the Desk

The device I am testing is entirely silver, except for the frame on the upper side, which is black. I don’t like that on some parts of the device, you can see traces of paint underneath. The device is not very well painted in silver color. For example, the Smartmi P1 that I recently tested is also available in silver, but the color is much better; the difference is very noticeable.

In my opinion, it would be good if the designers installed handles for easier carrying. Still, since this is not a giant air purifier, you probably won’t have any problems transporting it from room to room. The plastic is not top quality, but that is not a big deal.

All in all, this air purifier is one very lovely device, which will fit into almost any ambiance. It will fit nicely on a desk, dresser, nightstand in the bedroom, or in a similar location.

Control Buttons

The device control buttons are located on the top. Touch buttons are well responsive even on the slightest pressure. Each time you press the button, you will hear a beep.

Medify Air MA-15 Air Air Purifier - Controls

In my opinion, the buttons are kind of small, so sometimes it happens that I don’t press the correct button.
There are Child-Lock, Timer, On / Off, Speed ​​, and Dimmer button on the button bar.

Airflow

The MA-15 has openings on the sides. The device draws in air through these openings, which is then filtered and exits through the openings on the upper side. The device draws air through openings on the sides because the two filters it uses are arranged there.

When placing the device in the desired location, be sure to move it at least 6 inches away from the wall or other objects.

Size and dimensions

The Medify MA-15 air purifier weighs 5.8 lb. The low weight allows you to move the air purifier from one location to another without a problem. The dimensions of the device are 8.9 x 8.9 x 14.6 inches.

What’s in the box?

When you buy the device, you get Medify Air MA-15,1x AC Power Adapter, True HEPA Filters, and a User manual.

Packaging is standard cardboard packaging. The filters are immediately inserted into the device. However, it is necessary to remove the plastic bag and reinstall them before the first start.

Features

The Medify Air MA-15 has a “Timer” as an optional extra option. The timer can be set to 1x, 2x, 4x, or 8x hours. This is a valuable option if you need to set the device to turn off after a certain amount of time.

Child Lock

This is also a handy option, especially if you have a small child.

Namely, after the Child-Lock is activated, the air purifier will not react to any button’s pressure.

Holding your finger on the Child-Lock button for 3s will activate it. Likewise, a 3s re-hold will deactivate it.

Dimmer

Press the Dimmer button to change the backlight to a certain brightness.

There are 4 brightness levels to choose from. Each time you press the Dimmer button, the level changes. Also, in addition to the 4 lighting levels, it is possible to completely dim the lights on the buttons. All you have to do is keep pressing the Dimmer button until all lights are off.

Filter Replacement Indicator

This is one of my favorite options that an air purifier can have. The filter replacement indicator makes it much easier to use the device by notifying you when it is time to replace the filter. This way, you don’t have to manually track when it’s time to replace filters, but you can entirely rely on the indicator.

Room Coverage and CADR

Medify MA-15 is a slightly smaller device, but it has excellent performance thanks to a powerful engine. MA-15 is designed for rooms up to 330 sq. ft. This device will clean the air in a room of 165 sq. ft. in just 15 min, while in a room of 330 sq. ft. the air is clean in about 30min.

These are laboratory results listed by the manufacturer. However, users will not always use the device in ideal conditions, so I suggest you keep on reading the Medify MA-15 review, where I will write more about the performance and other tests I did on this outstanding air purifier.

Filtration

Medify Air MA-15 uses 3 stage filtration. The device uses two identical filters, which are placed on both sides. You can find this identical filtration principle on the Levoit LV-H128 model, which I had the opportunity to test recently. What I really like about MA-15 is that it uses a True HEPA filter.

Medify Air MA-15 Replacement Filters

Always buy genuine filters for the best performance. As soon as the filter reset indicator is on, you are ready to change filters. Do it as quickly as possible.

Pre-filter

The first stage of filtration in the MA-15 is the pre-filter. It is a nylon mesh attached to a True HEPA filter. Its purpose is to capture large particles and thus extend the life of the HEPA filter.

This pre-filter type is very common in Levoit models such as the Core 300, where the pre-filter is also attached to the HEPA filter.

True HEPA H13 Filter

The second stage of filtration is the True HEPA filter. This filter has the power to remove up to 99.9% of airborne particles as small as 0.1 microns, such as allergens, pollen, dust, germs, pet dander, odor, mold spores, and smoke from the air that passes through the filter.

I really like that the MA-15 uses a True HEPA filter, as many devices on the market do not have True HEPA filters.

Carbon Odor Filter

The third stage of filtration is the carbon filter. Its purpose is to eliminate household odors and VOCs (volatile organic compounds) gases as shown by independent laboratory testing.

Medify MA-15 uses carbon pellets. However, the amount of pellets in the filter is very small, and they are not densely arranged at all. I don’t like that at all, and I think that’s why the gas filtration is a bit weaker with this device.

The MA-15 would be a much more complete and better device if it had a carbon filter in line with the quality of True HEPA filters.

How to Replace Medify Air MA-15 Filters?

The filters on the MA-15 are not washable, so they need to be changed at a certain time. With this model, the filter will last about 2500 hours, approximately 3-4 months.

The good thing is that the Medify MA-15 has a built-in filter replacement indicator, which will notify you when it’s time to replace the filter. Besides, I would recommend that you clean the inside of the device at least once a month and remove the dirt accumulated on the pre-filter.

Total time: 10 minutes.

Step 1

Unplug the air purifier. Remove filter cover on both sides by pushing the lockers on top of the cover.

Step 3

Before installing a new filter, you can use a vacuum cleaner on the insides of the air purifier to remove any accumulated dust. A new filter needs to be installed with the white side facing out.

Noise Test

Medify MA-15 uses 3 fan speeds. The engine has a vast airflow. I can say that I was a little surprised about it, considering that this air purifier is not that big.

Medify Air MA-15 Air Purifier - Noise Test

The biggest airflow is at the third speed, which is also the loudest speed, so it will be a problem for many users to use the device constantly at the highest speed. The first and second speeds are much quieter, and it is much easier to stay indoors if the machine is running at either of these two speeds.

Speed Value (dBA)
Speed 1 41.2 dBA
Speed 2 47.1 dBA
Speed 3 61.1 dBA

My complaint is that the MA-15 has no sleep mode. However, at the first speed, it produces 41.2 dBA of sound, which is as low as some competing devices in sleep mode. Also, the Dimmer button can be used to dim all the lights on the device, and in this way – in combination with the first fan speed we can get something similar to what we would get with sleep mode.

Performance Tests

Medify Air MA-15 air purifier is a small device, but it is nevertheless intended for rooms up to 330 sq. ft. This is the first such a small device, which I have tested so far, and that it is intended for rooms up to 330 sq. ft. 

Medify MA-15 Air Purifier - Performance Test

Many, much larger devices, such as the Winix C535 or Hathaspace HSP001, are designed for rooms of similar dimensions but are also several times larger than the MA-15. Given the specifications, I tested it in the recommended dimensions, and I was pleasantly surprised by its efficiency. I am glad that one smaller device can produce so much airflow and make solid performance. Below I will show the tests in two separate rooms where I tested the Medify MA-15 air purifier.

194 sq. ft. Room Test

I tested the MA-15 in a 194 sq. ft. room. This room is slightly smaller than recommended. I tested the device for 60min, the air purifier worked all the time at the highest speed.

# Starting Baseline After 60min
PM 2.5 98.9 7.6
PM 10 138.5 10.6
Particles 143521 11038
AQI 129 10

During that time, the MA-15 improved room air quality by about 92%, lowering the AQI from 129 to 10. This is an excellent result, and I can say that I am positively surprised.

320 sq. ft. Room Test

I also put the device to the tests in a 320 sq. ft. room. And in this room, the device was running at third speed all the time.

# Starting Baseline After 60min
PM 2.5 96.8 10
PM 10 135.5 14.1
Particles 140366 14604
AQI 127 13

In just 60 minutes, the device lowered AQI from 127 to 13, thus improving air quality by about 90%. This is also an outstanding result and just as unexpected as in the previous test. The MA-15 is one compelling device by all accounts, which didn’t let me down on performance tests.

Operating Costs

Medify Air MA-15 air purifier uses a very small engine, which has a power of only 25W. The device uses an AC adapter, which comes in the purchase box.

Medify Air MA-15 - Operating Costs

Air purifiers do not normally consume much electricity, and that is also the case with this device. If you leave the Medify MA-15 running for 24 hours non-stop, at top speed, and so on for a month, you will pay about $ 2. This is not such a high figure, especially considering that you will not be using the device at the highest speed all the time.

Speed Power Usage (W)
Stand-by 0.9W
Speed 1 2.2W
Speed 2 5.3W
Speed 3 23.7W

Slightly higher costs are replacement filters, which in my opinion are too expensive. Another problem besides the cost of replacement filters is the frequent replacement of filters. Namely, it is recommended to change the filters on average between 3-4 months.

Although the MA-15 is not a large energy consumer, the cost of replacement filters and frequent replacement leads to the MA-15 having slightly higher maintenance costs on an annual basis overall.

Medyfy Air Warranty and Customer Service

At first glance, the lifetime warranty offered by Medify Air is very tempting and sounds just amazing. However, I don’t like that this warranty is conditioned in some way. To be valid, the manufacturer “forces” you to change the filters every three months and always use original filters, which are not cheap at all.

Also, 30 days from the product’s purchase, you need to register it on their webshop and thus start your warranty. My recommendation is to read the warranty agreement and, therefore, better understand how the Medify Air warranty works.

In addition to the warranty, customer support, and the way the company treats customers are very important. I tested the support via email and via the Facebook page. I am satisfied with the speed of response I received through both channels. Some of the answers were a bit generic, but that’s probably because I asked simple questions that many users ask.

FAQ

Does Medify Air MA-15 produce ozone?

No. Medify MA-15 does not use Ionizer, UV-C, or any other form of filtration that could produce ozone. The device is entirely safe to use.

How long is the warranty on the Medify MA-15?

Medify offers a lifetime warranty on this device. However, the warranty is subject to regular filter replacement.

How often should the filters be changed?

The manufacturer recommends that you change the filters on average between 3-4 months.

In which rooms is it best to use this device?

This is a small but strong device, so you can use it in any room up to 330 sq. ft., even in somewhat larger rooms. My recommendation is not to use it in rooms where there is a lot of smoking because the carbon filter is not that powerful.

Pros and Cons

To revise, here are advantages and disadvantages of Medify Air MA-15:

Pros

  • Very small Energy Consumption
  • Energy Star and CARB certified
  • 2x True HEPA H13 filter
  • Very High Airflow for Such a Small Device
  • Available in a Unique Silver Color
  • SolidPerformance on Tests
  • Good Customer Support

Cons

Final Thoughts

Medify is a brand that offers a variety of very popular models. In this review, I tested one model from their series of smaller air purifiers.

Medify MA-15 is an air purifier with a beautiful design, very high airflow, double true HEPA filter, and excellent performance. However, I would like to emphasize that the device’s maintenance is not proportional to its price, which leads to the fact that you will only spend more on replacement filters per year than you paid for the device.

Overall, I am delighted with the performance and what the Medify MA-15 air purifier offers. If slightly higher maintenance costs are not a problem for you, then my absolute recommendation is this device.
