In-depth Review of Medify MA-40:
HEPA Filtration: It seems like a great air purifier with its high specifications and beautiful design. They advertised the unit has medical grade H13 class HEPA filter, but this is a bit confusing. H13 class is air filter rating on Europian standard (EN 1822-1:2009) which efficiency is 99.95% at 0.12-0.25 microns. On the other hand, true HEPA filter efficiency is 99.97% at 0.3 microns on US standard. So, this medical-grade is sort of a marketing term though the filter is true HEPA which is good news.
Activated Carbon Filter: The activated carbon filter will help to absorb VOCs and odors from the air. They didn’t mention the total surface area of the activated carbon substances, but it looks thick, and it performs excellently to remove odor.
The filter set is included with a pre-filter and an activated carbon filter. The combined filter set is easy to install or replace. However, the combined filter set has some downside. As we know, the activated carbon filter got saturated quickly than the HEPA filter, so the performance of the carbon filter could be down after a couple of months’ usage. The filter set has 3000 hours of life, which is excellent. But the replacement cost per year is a bit higher compared to the other. Check latest filter price
Another downside of the combined filter is the pre-filters are not washable. Although, you can clean the filter surface gently with a dust cloth. The filter set needs to be replaced every six months or 3000hrs of usage.
Anion filter: The unit has an ion generator in its filtration system. However, it is optional and turns it on will give you some boost (8% increase in CADR) in air cleaning. They claim it is ozone free though all ionizers produce some amount of ozone. Ozone has some kind of metallic smell, and Medify MA-40 doesn’t smell noticeable when the Anion is turned on, so it looks like the ozone emission is very low.

Coverage, CADR, and ACH: The company claims Medify MA-40 can clean a room of 800 square feet with 2 air changes per hour (ACH). So, we can calculate its actual CADR in cubic feet per minute with the formula: CADR = (2 ACH x 800 sq ft x 8 ft ceiling)/60 minute = 213 cfm or we can convert 330 cubic meter/hr = 194 cubic feet/minute. Don’t confuse with the advertised 330 CADR which is in cubic meter per hour.
However, 194 CFM is enough for a medium-sized bedroom of 200 square feet, where you will get 8 air changes per hour, or it takes 8 minutes to clean the air from the entire room. Thus this could be a great choice for selecting an air purifier for smoke or heavily contaminated air for 200 square ft room. Find your required air delivery rate with our simple CADR Calculator.
Noise: On the highest fan speed, you will get a noise level of 66 dB, which is not the quitter. For reference, the average sound level of a vacuum cleaner is 70 dB. On low-speed setting, it’s around 50 dB, but the performance (CADR) will drop. However, from the noise level perspective, this is not a quieter air purifier.
Particle (PM2.5) Sensor: Medify MA-40 has a built-in PM2.5 particle sensor that works fine most of the time. The indoor air quality displays on the front panel as blue, green, and red, which looks cool. Also, automatic mode runs based on its PM2.5 sensor.
Control: 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 and an automatic mode. Automatic mode works very nicely based on its PM2.5 sensor. You should clean the PM2.5 sensor regularly to get the best result. 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.
Night Mode: It has a night mode that activates the dark environment. Night mode only actives if the automatic mode turns on. On night mode, all indicator lights turn off except the power and front air quality display indicator. The fan runs low on night mode.
Child lock: Child lock is another useful feature for preventing any unwanted button pressing on touch. Though you need to press the button for 30-45 secs to deactivating the child lock, which is kind of annoying.
Power: The rated power 68W is a bit high compared to other air purifiers in its category. The monthly operational cost will be no more than $3 (at $0.12 per kWh energy rate) on daily 15 hours of usage. The unit runs on 110-120 V AC at 60 Hz.
