Medify MA-112 is a clean, modernly designed air purifier that is surprisingly not that big given its strong airflow performance. At a 16 x 28 x 15 inches dimension, that are other bigger units that take up more interior space yet without the matching output. Available in 2 colors, the side air inlets support dual air intake is common across Medify air purifier lineup. The only downside is the heavy 32 pounds weight that makes it difficult for room-to-room purifying.

Usability is another strong suit of Medify MA-112 air purifier. It comes with a built-in sensor to support the AQ indicator and auto mode. The air cleaner will automatically run at a higher speed when there is a high concentration level of pollutants detected. There are also 4 variable speeds, 4 preset timers, ionizer, and sleep mode. Under notable features include a child lock that prevents children from changing the setting, a light button that dims all indicator light, and a filter replacement indicator that reminds you to change the filter after 3,000 hours of runtime. Build quality is spot on with tight removable panel fitting and a premium touch screen control panel. No misalignment or off-gassing can be found here.

Medify MA-112 comes with all the safety certifications that are safe for children and baby use. It is CARB (California Air Resources Board) approved ozone-safe, AHAM tested, UL, and ETL listed. Backed by a lifetime warranty that covers any manufacturer defects with original Medify filters purchased.

Filters And Performance

Why settle for True HEPA when you could go with medical-grade filtration used in hospitals? Medify Air MA-112 air purifier comes with a dual air intake that is protected by 2 pre-filter. The pre-filters will block large particles like dust, hair, fiber, lint from passing through and prevent the HEPA filter from getting clogged. The dual H13 filter removes 99.9% of microscopic particles as small as 0.1 microns e.g. lead dust, dust mites, mold, pollen, pet dander, bacteria, and virus carrier. The activated carbon filter absorbs common smoke and odor coming from pets, cooking, cigarette. It can also absorb toxic fumes e.g. VOCs, asbestos, formaldehyde, and benzene. There is an optional ionizer that diffuses negative ions to latch nearby pollutants ions in the air. The latched particles will fall from the increased weight allowing the air purifier to pull in and capture the pollutants. Overall, the proven H13 filtration is super effective but can be costly to replace especially in the long run.

Noise And Energy Usage

Medify MA-112 H13 air purifier noise output can be as loud as a handheld vacuum at 70 decibels. It is distracting in everyday use but you can tone down the noise by running at a lower speed or select the Sleep mode to achieve the same result. Running at 100 volts, the power usage is not the lowest but it still qualifies as an Energy Star rated model. To better manage the energy rate, leave it in Auto mode and Medify will only use higher speed when indoor air quality level drops. We are averaging around $3.5 dollars a month on the electric bill but your result will vary based on the respective states.

Medify MA-112 air purifier 600 price tag is not easy to chew on for normal folks. For this price, you're getting all the good stuff, premium materials, and high-end H13 air filtration, Another issue is the close to 400 dollars filter replacement set that you will have to incur just 4 months (3,000 hours) down the road. Rather than opting for third-party filters to cut costs and void the lifetime warranty, there are cheaper alternatives that will do a similar job at the cost of the airflow output.
Amazon is the best place to get Medify MA-112 air purifiers. Hands down. It offers seasonal discounts, bundled filter pack deals, free shipping, and Amazon Prime perks, and a hassle-free 30-day return policy if you are not happy with the purchase. Medify official website is another good option that comes with a competitive price and identical perks although you will have to register a new account. You can try also your luck local dealers or retailers like Walmart, Target, or Best Buy but most of them won't carry the brand especially this high-end variant.
