Who is this for – Medify Air MA-40-W V2.0 air purifier with H13 HEPA filter?

  • A purifier for large spaces– the MA-40 is powerful enough to cover areas of up to 800 sq.ft.
  • Respiratory problems (asthma, allergies, and sinus) – this air purifier uses a 4-stage H13 True-HEPA filtration system to remove air pollutants. A True HEPA is a filter that has been certified to remove 99.97% of air pollutants 0.3 microns small. Medify Air claims to push these limits with its H13 filter that also removes 99.95% of air contaminants down to 0.1 microns.

    H13 is one of the 5 standard ratings used to classify True HEPA filters further according to their ability to remove pollutants measuring 0.1 microns. This rating starts from H10 to H14. The higher the number, the higher its efficiency. 
  • Smokers– this filter has a thick Activated Charcoal bed that most previous buyers affirm that it has incredible smoke removal capabilities.
  • Pet owners– the Activated Charcoal filter works not only for smoke, but strong smells, including pet odors too.


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.

Medify Air MA-40-W V2.0 air purifier with H13 HEPA filter reviews


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


Medify Ma-40 2.0 is a sleek and modern air purifier with H13 true HEPA filtration technology. The compact body is made with high-quality plastic with a glossy finish, which feels very premium by touch.

The top is fully covered with tempered glass, and the control panel is here, which is an entirely capacitive touchscreen with indicator lights. The ambient light sensor is placed on the top panel. This control panel features a child lock, timer, power switch, speed, and the anion controller button.

On the backside, there is a large air inlet and a carrying handle. The Air inlet has a removable cover for filter installment. As the filters are included in a single package, it is very convenient to install or replace the compact filter.

The front panel has a large air vent where the fresh air comes out and the Medify Air branding. The air quality indicator light has been removed from the upgraded 2.0 model.


The glass-top touch screen control panel is very convenient to use and feels premium to touch. The starting sound is charming. It has 3 manual fan speeds. You can manually turn ON or OFF the Anion, which generates ions to capture particles. A downside is it has no remote or app control features.

Child lock

Child lock is another useful feature for preventing any unwanted button pressing on touch. You need to press the button for 30-45 secs to deactivating the child lock, which is kind of annoying.

Night Mode

It has a night mode that activates the dark environment. Night mode only actives if the automatic mode turns on. All indicator lights turn off on the night mode except the power and front air quality display indicator. The fan runs low on night mode.

Medical-Grade H13 Filter

To trap allergens, eliminate odors and adsorb VOCs without air escaping between the layers, Medify put a huge three-in-one filter in the MA-40. This filter consists of an activated carbon layer, a pre-filtration layer and a true-HEPA layer.

Genuine HEPA filters come in varying levels of efficiency. The HEPA filter in this air purifier is a medical-grade H13 media. Therefore, it not only traps 99.97 percent of 0.3-micron particles but also 99.95 percent of 0.1-micron particles, achieving a level of clean that many other purifiers can’t reach.

Anion Filtration

The unit has a negative ion generator in addition to its air its filtration arrangement. However, it is optional, and using it will give the air purifier some boost (usually increase the CADR by 8%) in the air cleaning rate. Ionizer produces a small amount of ozone. However, the unit is ozone-safe and CARB approved.

However, you shouldn’t use the feature if someone has asthma or breathing difficulties at home.

Activated Carbon Filter

The activated carbon filter will help to absorb VOCs and odors from the air. They didn’t mention the activated carbon substances’ total surface area or amount, but it looks thick, which is suitable for remove odors, VOCs, and some gases.

Also, the compact filter includes a pre-filter layer to protect the primary HEPA filter.

The compact 3-in-1 filter is easy to install or replace. However, the combined filter set has some downsides. As you know, the activated carbon filter got saturated quickly than the HEPA filter, so the odor filter’s performance will lower after a couple of months’ usage.

The filter has 3000 hours of life, which is excellent. But the filter replacement cost per year is a bit higher.

Another downside of the combined filter is the pre-filters are not washable. Although, you can clean the filter surface gently to remove pet hair, dust, and lints. The filter set needs to be replaced every six months or 3000hrs of usage.


You will get a noise level of 66 decibels on the highest fan speed, which is not the quitter. For reference, the average sound level of a vacuum cleaner is 70 decibels.

On the lowest fan speed setting, it’s around 46 decibels, but the performance (CADR) will drop. However, from the noise level perspective, this is not a quieter air purifier.

Coverage, CADR, and ACH

The CADR of Medify MA-40 2.0 is 330 cubic meter per hour (m3/h) or 194 cubic feet per minute (cfm), which is capable of cleaning a large room of 800 square feet with 2 air changes per hour (ACH) or 400 square feet with 4 air changes per hour. This moderate CADR level is good enough for medium to large-sized rooms.

Medify Air MA-40-W V2.0 air purifier with H13 HEPA filter customer reviews

This air purifier makes a noticeable difference in my 1000 sq. ft. apartment. If I light a cigarette, just a moment later, the unit automatically amps up until the air is clear again and then it goes back to low speed. Even at high speed it is not noisy. Nice looking unit and not very large. Also very easy to operate – just plug it in and turn it on, set it to “Auto”. I’ve found the customer service to be great – I live in Canada and inquired about purchasing replacement filters and they responded immediately. The unit itself arrived very soon after I ordered it, which surprised me – I t
