Medify MA-15 Air Purifier Review: Small, Effective, and Cheap!

Last updated on April 19th, 2021

The starters

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.

Airflow, speed, and CADR

Being one of the best affordable air purifiers in the market, Medify MA-15 can cover up to 330 square feet of room space in mere 30 minutes. You can select between the 3 preset fan speeds based on operational hours. For example, set it to max speed when you are away for work or holiday, set it to low speed when you need clean air to breathe in with peacefulness in mind. Take note that Auto or Sleep mode is not available here so everything has to be done manually. Medify MA-15 CADR mirrors the impressive airflow output. Clean air delivery rate or CADR measures how fast an air purifier can remove particulates in a room. Under a fixed environment, it can deliver 150 cubic feet per minute (CFM) of clean air free from dust, pollen, and smoke. Safe to say Medify MA-15 is ideal for medium room sizes e..g. bedroom, kitchen, dining area, walk-in wardrobe, office, or studio room.

What’s inside count

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.

Keep it down

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.

At what 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.
