Update on Version 2.0: The newer version, which has been released back in March 2020, is known as Medify MA-40 v2.0. In the newer version 2.0, Medify Air removed the particle sensor (PM2.5) and the automatic feature since they found it is ineffective. According to their test, the sensor only detects airborne particles nearby the air purifier instead of the whole room.

Aesthetics

Medify Ma-40 v2.0 is a modern-looking air purifier with a higher-grade H13 HEPA filtration technology. The body is made with high-quality plastic with a glossy finish, which feels very premium by touch.

Front: The larger air outlet is located on the front alongside ‘Medify Air’ branding. The air quality indicator light has been removed from the upgraded 2.0 model.Medify MA-40 Air Purifier back with cover open and filter set

Back: On the backside, there is a large air inlet and a carrying handle. The back cover has magnets for an easy locking mechanism. As the purifier comes with a composite 3-in-1 filter package, it is very convenient to install the filter.

Medify MA-40 V2.0 Control and Display Panel

Top: The top is fully covered with tempered glass. The control and the display panel is located here. The controls are based on capacitive touch technology. This touch control panel features a child lock, timer, power switch, fan speed, and ionizer switch.

The timer has four modes: 1h, 2h, 4h, and 8h. It has 3 manual fan speed settings and a sleep mode. The indicator lights turn off when the sleep mode activates. It doesn’t have an automatic fan speed mode since the particle sensor has been removed from version 2.0. A filter replacement indicator is also located on the top panel.

The left and right sides are solid. It stands on four small feet.

In-depth Review of Medify MA-40 v2.0:

H13 Class HEPA Filtration

Medify MA-40 comes with an H13-grade HEPA filter as the core particle filtration, a high-grade particulate filter. The removal efficiency of an H13 class HEPA filter is 99.95% at 0.12 – 0.25 microns (MPPS). They can capture tiny airborne pollutants such as fine dust, smoke particles, and microorganisms. Medify claims their filter can remove 99.9% of particles that are sized down to 0.1 microns.

The first layer of the defense is a pre-filter net. The pre-filter traps larger pollutants such as lints, pet dander, mold spores, and dust. It also prevents the core HEPA filter from getting clogged so much early.

Pellet-based Activated Carbon Filter

The last stage of the composite filter is an odor and gas filter. The honeycomb-shaped filter is filled with activated carbon pellets, which adsorb odors and VOCs from the air. Medify didn’t mention the amount of the activated carbon material used in the filter, but it is thick enough to remove light household odors.

The composite filter is convenient when it comes to maintenance. However, the combined filter has some downsides. As you know, the activated carbon filter becomes saturated earlier than the HEPA filter, so it is not possible to change the carbon filter independently.

Another downside of the combined filter is, the attached pre-filter is not washable. Although, you can clean it gently to remove accumulated dust from the filter surface. The filter needs to be replaced every six months or 3000 hrs of usage. It looks like the filter replacement cost per year is a bit higher.

Optional Ionizer

Medify MA-40 v2.0 also has an ionizer add-on as optional. When it is turned on, it releases charged particles to be attached to the dust floating in the air. Then the heavy particles fall to the ground.

The ionizer only helps to remove particles from the air and cannot remove odorous pollutants. It usually increases the particle CADR by approximately 8 percent. Ionizer filtration also releases a small amount of ozone as a byproduct. However, the unit is ozone-safe, and CARB approved.

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

Room Coverage, CADR, and ACH

Medify MA-40 v2.0 has a particle CADR of 380 cubic meter per hour (m³/h) or 224 cubic feet per minute (cfm). You will get 2 air changes per hour in a 840 square feet room and 5 air changes per hour in a 336 square feet room. When the indoor pollution is higher, the more air exchange rate is better.

With the CADR ratings, the purifier is suitable for medium to large rooms based on your desired air exchange rate. Please check out our recommendations below for room coverage.

Noise Level

The air purifier’s noise level is 46 decibels on the lowest fan speed and 66 decibels on the top fan speed. The noise level is slightly higher compared to the air delivery rate. For reference, 70 decibels is the level of noise generated by a vacuum cleaner.

The minimum noise is 46 decibels, which is not “very quiet.” So if you want to use it in the bedroom at night in sleep mode, you have to keep it a little away from the bed.

Child lock

Control panel lock is another useful feature for preventing any unwanted setting changes by touch. You can easily activate it by tap and hold the Child Lock icon for 3 to 5 seconds. However, you have to tap and hold the icon for 30 to 45 seconds to deactivate the child lock, which seems annoying.

Warranty

Another advantage of this mid-range air purifier is that you will get a lifetime service warranty from the manufacturer. To claim the warranty, you must have to use the original replacement filter every 3000 hrs of usage.

Certifications

The air purifier doesn’t have an AHAM verification for the CADR rating. However, it is Energy Star certified, and CARB approved.

Suitable Room Size for Medify MA-40 v2.0:

*The room size calculation is based on an ideal situation. For best practice, consider the size of the room a little less than the calculated value.

      Yes, it’s normal as it operates based on surrounding air quality in automatic mode. Don’t forget to clean the air quality sensor with a dry cotton swab every two weeks to get accurate air quality reading.

    The air that it blows out, does this air purifier turn it hot? Or is it the same as what is being sucked in?

      Here is the answer from J Henry Scott, founder of Medify Air: You can and should run the unit 24/7. I have run mine on speed 2 for a year now and I designed these. And when I leave the house, I turn on highest to turbo clean the air. The air is return at the same temperature.

      From us: Since it has an electric motor inside, it must be a little hot when running it 24/7. The heat will release into the air it delivered, although it is nothing remarkable because the air purifier is designed to run 24/7.

    Which Timer mode should I use. The room is 1450 square feet. Should I use 1 hour, 2 hour, 4 hour, or 8 hour

      The air purifier has a maximum airflow of 330 cubic meter per hour. At this rate, it will take one hour to clean a 1450 square feet closed room (8 ft. ceiling) theoretically. So, if you run the purifier on top speed, you can use a 2-hour timer on the specific room to filter the air. However, it is suggested to run the air purifier 24/7 at the lowest fan speed.

      A HEPA filter equipped air purifier can effectively reduce the tiny particles or droplets in the air that might convey the virus. The HEPA air purifier will inhibit the spread of Coronavirus when someone tests positive or showing symptoms and currently self-isolating at home.

      No, this is not 100% ozone-free as it has an optional ion generator. These models are 100% ozone-free from Medify: MA-14, MA-18, and MA-Smart. Here you can find the top 100% ozone-free air purifiers.
