Medify Air MA-15 weight
6.6 lb (3 kg)

A compact, HEPA air cleaning machine that stands at only 9.7 inches in diameter and 15.5 inches in height. Medify MA-15 is a highly portable air purifier where you can leave it on the work desk in the morning and bring in to the bed during night time. The lightweight 6.6 lb makes it carrying around simply by gripping on the handle. Surrounding the white modern exterior is the air inlet that sucks pollutants in and a huge top air outlet that distributes clean air out. Fitting is tight with zero off-gassings detected despite the plastic built. Expect the same build quality as other premium air cleaner models that cost 2-3 times more.

Moving to functionality, Medify MA-15 modern exterior is very easy to use thanks to the familar yet distinctive buttons. Starting from the left, you have the child safety lock button that locks the control to prevent children from meddling with it. A timer button that allows you to set between 1, 2, 4, or 8 hours when to shut down the air purifier, dedicated power off button that turn on/ off the machine, a fan speed button that allows you to cycle between the 3 speed, and a dimmable control light button allowing to dim the indicator light. There is also the filter replacement indicator that reminds you to change the filter after 2,500 hour or every 3-6 months.

To recap, Medify MA-15 air purifier is a compact, 3 speed, 4-stage H13 HEPA filtration air purifier with a built-in anion generator. It is ozone-safe, UL listed, AHAM tested, and comes with a lifetime registered warranty. You will never have to worry about manufacturing defects as long as it is equipped with Medify official filters and used within the U.S.A.

Filters And Performance

Despite the low price, Medify Air MA-15 is equipped with a dual intake 4-stage HEPA filtration that can capture all types of airborne contaminants. When air is drawn in, the pre-filter will block large particles like dust, hair, fibers, lint from proceeding. The medical-grade H13 TRUE HEPA filter will remove 99.9% of allergens as small as 0.1 microns e.g. dust mites, mold spore, pollen, bacteria, and viruses. The carbon filter with carbon pellets absorbs pet odors, cooking smells, cigarette smoke, musty mold, chemical fumes from cleaning products e.g. VOCs, asbestos, formaldehyde, benzene. Last but not least, the anion generator diffuses ions that latch to nearby pollutants in the air. The now merged ions will fall due to heavier weight allowing the filter to capture.

Overall, the filter quality is decent for its segment but we would prefer the use of a larger filter than the dual filter setup. The permanent pre-filter is washable so it should save you a lot in the long run. The optional anion generator is a nice feature to have and you can disable it at any time especially if you are an asthmatic person with sensitive lungs.

Noise And Energy Usage

Medify MA-15 has a modest 35 dBA noise output when you moderate at the lowest speed. Not the most silent air purifier in the market but it will not disturb your workflow or sleep during operation. At the highest speed, the fan noise is at 51 dBA which is audible but not overly loud. As for power usage, Medify MA-15 is very energy efficient hovering around 18 watts per hour. With 12 hours of continuous runtime, the estimated electricity cost is around $0.03 per day, $1 a month, or $12 dollars a year. For the recommended 24 hours, just multiply the numbers by 2 and the cost is still low compared to other home appliances.

^ Replacement filters/ estimated cost
At such an affordable price point, we can hardly find any fault with Medify MA-15 air purifier. It comes with genuine 4-stage filtration including a medical-grade H13 HEPA filter. The H13 filter itself is worth all the money you paid for. Staying with the filter topic, the 70 to 140 dollars recurring cost is rather steep given how cheap is the air purifier is selling at. Then again the filter cost is justifiable as you are using a dual filter set and have to replace it every 2500 hours or 3-4 months. If you can't bear the high filter cost, this is not the right model for you.
There are limited places you can get Medify MA-15 air purifier or any of the products from its lineup. Amazon is definitely the first place you should try as it offers great discounts, instant rewards, free shipping, and an assuring 30-day return policy. Medify official website is also a great option as it comes with almost similar perks and hassle-free purchases. Retailers like Walmart, Best Buy, Home Depot, Costco does carry electronic appliances but availability is subject to the store.

TREDY HEPA Air Purifier TD-1500 Review


Cheaper and comes with an air quality indicator, auto mode, sleep mode. You do have to compromise with a smaller purifying coverage and fewer filtration.
Levoit Core 300 True HEPA Air Purifier Review

LEVOIT Core 300

Identical but comes with slightly weaker airflow performance and CADR. Loses out on the ionizer feature but gains the upgradable filter option.
