Medify Clean Air Solutions is known for manufacturing high quality air purifiers for homes, offices, schools, universities, classrooms, hospitals, restaurants, businesses even cars.

Their focus on creating air purifiers that offer superior indoor air quality came from their founder’s concern about indoor air pollution. One way they address that is by exclusively using HEPA H13 filters in Medify air purifiers. They also have COVID rated air purifiers that have been independently tested.

Following our review of their current product line, here are our recommendations:

All Around Winner: Best Medify Air Purifier

Medify Air Purifier – Up to 840 sq. ft. – COVID Tested

Best Medify Air Purifier

The Medify MA-40 is our best all-around Medify Air Purifier pick. It is rated for rooms up to 840sf, and has been independently verified to remove 99.99% of airborne COVID-19 (SARS-Cov-2) particles. Before diving into the MA-40, we did want to note that it barely edged out the MA-50 due to it’s price.

If you’re looking for both COVID particle removal and UV disinfecting, check out the MA-50 below.

True HEPA H13 Protection

The Medify MA-40 is one of the best selling and most highly rated units the company sells. Whether used in a home, medical, dental or office setting, the MA-40 provides True HEPA protection.

To extend the life of the HEPA filter, it also has a pre-filter to capture larger sized particles. And, active carbon takes care of any odors that need to be addressed.

Medify notes that their H13 filtration goes beyond the H11 filters used in other brands. While being effective at removing pollen, dust, mold, bacteria, dust mites, smoke, lead dust and pet dander, the H13 filter does more. It also combats asbestos, bacteria, carbon dust, insecticide, paint pigment, tobacco smoke, virus carriers and even anthrax.

Room Size and Fan Speed

We noted the 840 square-foot room size earlier. In a room of that size, the unit can purify all the air in 30 minutes. That also sets its coverage at 1,600 square feet every hour and 420 square feet in 15 minutes.

The unit is simple to use and has a high quality build. The control panel is a tempered glass touch-screen that is easy to read and operate.

Like most Medify air purifiers, the MA-40 has 3 fans speeds to choose from. On its lowest setting the unit operates at 46dBA. At its highest, it is 66dBA. Other notable features include an ozone-free ionizer which can be turned on or off, a child lock and sleep mode.

Air Filtration and Cost of Operation

Medify’s high-quality H13 filters run in the $50 to $60 range. The manufacturer estimates a filter life of 4-5 months. They’ve arrived at that number with a 3,000 hour filter life.

Electric consumption is nominal at 68 watts. Overall, we’re impressed with the cost of ownership for this level of air purification.

Reviewer Notes

One 5-star reviewer noted “We have been surrounded by wildfires for two weeks. Not able to open windows, for days at a time, with smoke trapped by cloud cover overhead, we were miserable. The purifier immediately cleared the house of smoke, and the tiny particles that come with it.

Review of Medify MA-40

“This product is what I have been looking for, medical grade HEPA filtration.” He continued to explain “finally woke up with out any breathing issues or being stuffed up.”

MA-40 Air Purifier Owner

Another verified buyer rated the Medify 40 at 5 stars stating “We absolutely love our MA-40. We put it in our living room/kitchen area. When we cook, we notice the smells disappear quickly. We have also noticed our allergies have virtually disappeared and that the dust level in our house is a lot less! The unit is very quiet and looks great in our house. I would not hesitate to recommend this purifier to anyone in the market for one.”

Premium Air Purifier: Medify True HEPA COVID Air Cleaner with UV Disinfection

Medify MA-50 COVID/UV Disinfecting Air Purifier – up to 1,100 sq. ft.

Best Medify Air Purifer: MA-50

Right on the heels of the MA-40 is the newer Medify MA-50. The MA-50 boasts not only COVID particle removal but also UV light disinfection. This Medify air purifier is also capable of handling larger rooms at home or the office – up to 1,100 square feet.

It is easily arguable to say that this is the best Medify air purifier as opposed to the one above. The only reason the MA-40 edged out the MA-50 is because it is more affordable. The MA-50 is clearly the premium air cleaner, especially for those with allergies or anyone looking for the best possible air filtration.

H13 True HEPA Plus UV Light

UV light has long been used in air purification in addition to traditional filters. Some industrial air scrubbers have even started to use UV light for restoration and renovation use.

With its combination of 3-layer filtration and UV-C light, the MA-50 is adept and removing smog, smoke, pollen, pollutants, virus, allergens, odors, pet dander and just about anything else that might pass through it. Of all Medify units, this one currently provides the highest level of air cleaning power.

With it’s higher level of air purification and COVID particle removal, Medify was targeting a broad audience which includes doctors, dentists and other public businesses. Of course, that protection is welcome in the home, too.

One notable difference that the MA-50 has which many others do not is 4-sided air intake. This means the unit is drawing air from the room in from all sides. All of the purified air is returned to the room through the top of the MA-50.

Room Size and Fan Speeds

Medify says the MA-50 can clean 1,100 square feet of air in 30 minutes, 2,200 in an hour, or purify 550 square feet in 15 minutes. Four fan speeds are available, and the unit boasts a quiet 35dBA on its lowest setting. On the highest fan setting, noise is a very respectful 56 dBA. We think the low noise level is a byproduct of the 4-sided filter design. Those filters seem to be also reducing noise from the air purifier’s motor and fan.

Air Filter Replacement and Cost of Operation

Filters for this premium unit run around $60 or $70. For the level of air purification the unit provides, it is reasonable. Filters are expected to last 2,500 hours which Medify says is about 3-4 months for the average user. But, for homes wanting the best level of protection, that’s probably not much of a concern.

Reviewer Notes

Complimenting the air purifer, one reviewer said “It’s whisper quiet even on the level two setting, we turn it up higher overnight or when we’re out of the house to get increased air circulation and filtering – then drop it back to level two and let it run 24/7. We love it! Couldn’t be happier with Medify Air!”

MA-50 Reviewer

Several reviewers commented on COVID prevention including this 5-star review: “I chose this because of the level of the HEPA filters. H13 helps to protect against viruses, while H11 (the standard) cannot. It’s good to know that we are doing what we can to keep COVID out of the air here.”

Review from Verified MA-50 Purchaser

Many reviewers own multiple Medify units. Here’s an example: “This is the second air purifier I have bought from this company. The first was for my work. This one is for my house. The performance is perfect.”

Review Notes

“I have COPD and I have animals I sleep with in my room. The MA-25 has allowed me to sleep and breathe so much more comfortably. I wake up feeling rested as I didn’t before.” stated a verified purchaser on Medify’s website.

Another noted she “bought this for my mom, who has an auto immune disease. She occasionally travels to my sisters and when she does has to lug a 3ft purifier in her car. This one seemed like it would be easier to move plus hospital grade quality was a HUGE PLUS. Since receiving my mom has commented on noticing a considerable upgrade in air quality…”

“The air purifier has been working really nice in our house. I like all the bells and whistles that come with it. It has variable speeds, night mode and a timer. It cleans the air of a large room very quickly. I have had a hepa filter in the past, but nothing compared to the quality of this air purifier. This has a sleek profile, looks cleans and compliments my room. My favorite feature is how clean the air smells.” another reviewer said.

Review Notes

I am so happy with the Medify Air MA-112 air cleaner. I have been using it for approximately 3 weeks for cigarette smoke. My building is supposed to be non-smoking, but like every other apt building I’ve lived in, in the U.S., it’s not. I have facial migraines that make me have sinus infections chronically which leads to more antibiotics. I have tried five other kinds of air cleaners and none of them worked. This really does work. The MA-112 cost more than I have ever spent on an air cleaner…and it is COMPLETELY WORTH IT!!!!!!

Review on Medify’s website

“I bought two of these units. One in June for living and kitchen area and one in August for the basement and I’m about to get a third one for my upstairs master suite. I believe these are the best air purifiers on the market. We had a birthday party for my father who is 72 and has asthma and was here for three or four hours and didn’t cough or wheeze once.”

5 Star Reviewer on Medify.com

The Medify Air Purifiers do their job and they do it very well. We bought a lot of purifiers from them for all of our schools. They are quiet machines – we even had a meeting yesterday surrounding an MA-112 and no one seemed to notice it was on! But what I like best about Medify is the incredible customer service!
