Medify Air is only a young company for air purifiers, but they only serve the top high-quality products for customers, just like what Levoit did. Also, this is the second air purifier company with lifetime warranty policy, which is clearly following the unique selling point of Alen. Medify MA-40 is the ace of this brand for many years, thanks to its high performance that can only be found from high-end machines. So today, we will dig deep with this Medify MA-40 Review.

Medify MA-40 Price

High fan power, phenomenal performance and a premium design combine to make this a fantastic buy for anyone looking for a more affordable flagship air purifier.

Looking at the Medify MA-40, it’s hard to believe that the company that made it was less than four years old. This is an air purifier that manages to hold its own alongside flagship devices from companies that have enormous pots of money to spend on research, development and design, and a decade or more of experience making air purifiers.

Medify Air has always made impressive air purifiers at sub-flagship prices, but with this iteration the American startup has learned from previous mistakes, and built on its successes, to create an all-round fantastic air cleaner device.

The Medify MA-40 sits higher than the Medify MA-Smart and Medify MA-25 in price, placing it firmly in mid-range segment with $349. But if you look for the air purifier in Medify Air’s website, you can find it usually down to only $274, which is just $50 higher than the previous model. It’s quite reasonable, because Medify Air decided to put in more power.

Levoit has a quick response for releasing the Levoit LV-H135, which is quite similar to the popular Medify MA-40, and reduce the price of the Levoit LV-H134 to a point it can compete with our today unit. You can also find the Winix AM90 or Honeywell HPA8350B in this price range, and both these devices have the Smart Wi-Fi connectivity function, something that the Medify MA-40 missed from the MA-Smart.

But hey, the Medify MA-40 is a great deal that you can’t just skip it. Do you like to take a deal of this air purifier at lowest price? If yes, then grab it now.

Medify MA-40 Design and Size

Medify Air produces two versions of the Medify Air, one is our testing unit with white color, and another to be the black version of this device. If you enjoy the more polished and premium black color option of Medify MA-40, you can get it below.

For some people, the Medify MA-40 is the best-looking device the company has made to date. Even the next-gen Medify MA-112 is following the design concept from this popular air purifier.

The Medify MA-40 is made in rectangular design than previous iterations, which means it stands firmly in the height of 22 inches and width of 10 inches. This size makes the air purifier smaller than both the Levoit LV-H135 at 25 inches and Winix AM90 at 23.5 inches.

Medify MA-40’s feel is premium with the perforated holes in the air grill. The device is clean and simple, which has rooted in Medify Air’s design from the first Medify MA-14 to the newest Medify MA-15. You will have an unusual back-to-front air flow system concept for a price in mid-range segment, however, it works very well for the overall shape of Medify MA-40.

On top of this air purifier, you will find an aesthetic glass control panel. Also, you will find the carved logo of Medify Air above the air quality indicator bezel. This tempered glass panel is used again in the newest Medify MA-25.

For the weight, the Medify MA-40 is 15.5 lbs. This is 50% increase in the weight of the previous model Medify MA-Smart. Luckily, you can move it quite easily with the convenient handle.

Medify MA-40 Filters

To decide the performance of one air purifier, normally we will check the quantity and quality of the air filters inside it, as well as the air filter types. As a mid-range air purifier of Medify Air family, the Medify MA-40 runs with a signature 4-stage air cleaning system as below.

  1. Pre-filter – A layer of pre-filter covers the True HEPA filter, to prolong the life time of the core filter, by trapping the large objects of pollutants like fur, hair and large dust.
  2. True HEPA filter – The True HEPA Filter (graded H13) that captures 99.97% of as small as 0.3 microns allergens, virus particles, pollen, mold and fungi particles.
  3. Activated Carbon filter – Uses substantial carbon filter with carbon pellets to remove toxic odors and formaldehyde.
  4. Ionizer – Produces negative ions to charge particles and trap them inside the unit. Can be switched on/off.

Like many air purifiers in Medify Air lineup, like Medify MA-18, Medify MA-440 and later, Medify MA-112, our today Medify MA-40 runs a high-quality H13 True HEPA filter, enhanced with the anion generator to trap any allergens with size down to 0.01 microns.

Moreover, the Medify MA-40 is fully tested by the California Air Resources Board (CARB) for meeting the safety ozone emission of 0.05 parts per million (ppm). This is a must-have standard for one product to be shipped and used in California, and with this certification, you can enjoy using the Medify MA-40, as it never trigger asthma or any other breathing issues.

The Medify MA-40 was tested in a room of 200 square feet and under 1 hour, just like many famous air purifying devices reviewed by Breathe Quality. In this test, I also used the Winix HR900, Inofia PM1539 and Oreck Air Response Large to compare with our today unit. As you can see from the below result, the Medify MA-40 was the best performer, with the highest efficiency of 99.95% for trapping any particles down to 0.3 microns in size.

There is only one disadvantage to use the H13 HEPA filter from Medify Air – the short life. You can only use it for 6 months, and replacing it at $69 each time is truly high for an affordable device.

Medify MA-40 Room Coverage

The big headline performance-wise is that Medify Air has decided to upgrade the performance of this Medify MA-40 a lot. It can cover a room of 400 square feet, which is better than even the more expensive Medify MA-440.

The ACH of Medify MA-40 is 2X to 4X. If the Medify MA-40 does only two exchanges in 1 hour, it can cover a space of 800 square feet. And for an ACH rating of 1X, the room coverage can be 1300 square feet.

The CADR of Medify MA-40 is 186 Dust/ 206 Smoke/ 246 Pollen (cfm). This high fan power is a bit less than the Inofia PM1539 and Winix U450 at the same price.

Medify MA-40 Sound

Medify Air doesn’t boast about the silent operation in this Medify MA-40 just like the latest Medify MA-440. That means the air purifier can’t hide the noise from its powerful fan, and if you want a device to clean the air in your bedroom, you should run on lowest speed.

The noise level of this Medify MA-40 is measured to be 65 decibels (db) on highest speed, which is fairly noisy to accept. The good news is that you have a Smart Sensor, to manage the fan speed as low as possible anytime.

Medify MA-40 Power Consumption

One of our most FAQs is “Do air purifiers use a lot of energy?” In fact, air purifier must be used for a long time to be efficient. And power consumption is one important criteria to review if this air purifier is good or not.

Power consumption is one of the few areas where a flagship can standout from its rivals, and the Medify MA-40 needs to keep it just low. However, you are using an air purifier with tremendous power, and you should be happy with the rated power of only 68 watts.

If you run the Medify MA-40 for 8 hours per day, it would cost you $24 each year.

Medify MA-40 Additional Features

Medify MA-40 returns the most high-end features from an air purifier, like the accurate Smart Sensor to enable Auto Mode and give you thoughtless air cleaning. This feature, for unknown reason, is unavailable in the latest Medify MA-440.

However, there is no Smart Wi-Fi connectivity function in this air purifier, which is exclusively for the Medify MA-Smart. Perhaps, you should wait a bit more for this feature to be available on Medify MA-40.

Again, we will have the basic settings like a Night Mode to limit the air purifier on lowest speed, or a Timer to schedule the time off for 1, 2, 4, or 8 hours. Medify MA-40 introduces the Child Lock for the first time in this family, to avoid children or pets from changing the current settings.

Finally, the Medify MA-40 has one LED indicator for filter replacement, so you can live a convenient life.
