What is the difference – Medify MA-25 vs MA-40

Portable design

It has the rectangular shape for its body. The Medify MA-25 Air Purifier is a lightweight and compact purifier at 7.3 pounds. It has the height of only 13.5 inches and the width of 8 inches.

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. 

Top panel

Medify MA-25

At the top of the model, where the outlet is commonly featured in most purifiers, you have the control panel. Covered by tempered glass, it allows easy access to the controls. You need to know that the tempered glass is scratch-resistant, unlike plastic.

Medify MA-40

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.

Suitable Room Size

The ACH of Medify MA-25 is 1X to 4X. If the Medify MA-25 does only one exchange in 1 hour, it can cover a space of 1000 square feet. And for an ACH rating of 4X, the room coverage is just only 250 square feet.

The CADR of Medify MA-25 is 147 cfm in general. Remember that Medify Air used m3/h for air flows unit, which they just said “CADR 250”.

Allergies and/or asthma5220 sq ft12 min
Smoke or highly contamination8140 sq ft8 min

If you have higher ceilings, use our Air Changes per Hour Calculator to calculate the suitable room size.

Noise

With a fairly low-power fan, the Medify MA-25 is only 35 decibels (db) on lowest speed, and I believe this is just the noise level of the library mode. On highest speed, the noise level only reaches 51 decibels, which is a lot better than many air purifiers with the same fan power, like Levoit LV-PUR131 or RENPHO RP-AP001.

In Medify MA-40, 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.

What are the Similarities – Medify MA-25 vs MA-40?

Build

Available in white, black, and silver, it’s made of ABS plastic. As such, it is impact resistant and can withstand corrosive action from chemicals. This makes the air purifier perfect for the kitchen and office.

Simple 3-Stage Filtration System

All Medify air purifiers have a 3-stage filtration system. The 3-stage filtration system is the industry standard. It includes 3 filters: pre-filter, HEPA filter, and carbon filters.

All brands – including CowayLevoitOkaysouWinixHathaspaceHoneywellBlueair, even Alen, to name just a few – use it to improve indoor air quality.

The how-it-works is simple: pre-filter captures large particles like pet dander, True HEPA filter captures small particles down to 0.3 microns, and carbon filter removes the gaseous odor.

The one between Medify air purifiers and other purifiers is that Medify uses H13 HEPA (captures down to 0.01-micron particles) instead of 0.3 micron True HEPA.

What is the alternate of Medify MA-25 vs MA-40?

Molekule VS Medify

It’s interesting to compare Molekule vs Medify air purifiers. Molekule’s new-age PECO filters are primarily designed to destroy (literally fry) bacteria and certain viruses.

Of course, all HEPA-based air purifiers try to do that as well but many bacteria and viruses are smaller than 0.3 microns (the lower size range of HEPA filters). Medify’s H13 HEPA filters, however, have a 0.1 micron lower size range.

Within 0.1 and 0.3 microns, there are a number of bacteria and viruses Medify air purifiers do capture.

However, capture is not the same as destroy. In the battle between Molekule Air and Medify MA-40, for example, Molekule Air will always wina because it destroys bacteria, not merely captures them.

Medify VS Levoit

Levoit is actually the closest air purifier brand to Medify in terms of the model range, CADR ratings, 3-stage filtration system, and even prices.

Example: Levoit LV-H135 vs Medify MA-40. Both have a 300+ CADR rating, cost about $300, and have a 400-500 sq ft recommended coverage area. Even the filter lifespans are similar.

There is one big difference between Levoit vs Medify, of course:

Levoit uses HEPA filters, while Medify uses H13 HEPA filters.

Essentially, for people with allergies, it makes sense to filter out as many air pollutants as possible. Medify’s H13 HEPA filters certainly do a better job than Levoit HEPA filters.

That means that Levoit still leaves out those smallest below 0.3-micron air pollutants in the air. Those are the ones Medify filters out of indoor air.
