You will adore this particular air purifier if you are looking for a device that can completely eliminate smoke, formaldehyde, and other harmful odors and particles from the air. Its 4-stage filtration system gives an incredible performance. Unfortunately, we did not like how noisy the device gets at high speed.

The details

Featuring H13 HEPA filters, the Medify Air Purifier does a spectacular job at removing different allergens and pollutants from the air. It has a tempered glass panel that is easy to clean and it is scratch-resistant. Whether its features or maneuverability, the unit is rated the best in each category.

Noise level

The air purifier is not a bedroom-centric product. Though lower settings of the fan might be suitable for bedroom use, it can still be loud for people who like to sleep in pin-drop silence. The loud noise level is due to its powerful fan so while it can efficiently remove all germs from the air, it does so very noisily. The highest speed level produces 65 dB which can be annoying for some.


The unit contains a 4-stage filtration process to clean all and every particle with an accuracy of 99.9%. To make it accessible for bedroom use, the unit has a ‘Sleep Mode’. Moreover, it also has a smart sensor that manages the speed of the fan precisely. The auto mode is enabled by the smart sensor and it sets the optimal speed level depending upon the quality of the air. The unit also adorns a child/ pet lock and an LED indicator for filter replacement.


The built-in filtration system is a 4-stage process that includes a pre-filter, true HEPA filter, activated carbon filter, and an ionizer. The filters do their best to remove all particles and unfriendly odors from the air. We noticed that the activated carbon filter is made from carbon pellets which are known for removing odors of smoke, wildfire, cooking smell, formaldehyde, and other toxic odors from the air. Furthermore, you have the choice of using the ionizer; it can easily be switched on and off.


With an impressive performance, the Medify MA-40 air purifier can be used for almost all purposes. It can clear out smoke, wildfire, cooking smells, pollen, pet hair, and every kind of pollutant that can be floating invisibly in the air. We liked the smart sensor and the auto mode since it makes using the unit convenient.

Final verdict

Overall, the unit is definitely worth buying. It offers great features, a strong filtration system, and portability. Although we were let down by the noise level, especially at high speed, it is still good enough to be used at homes or offices during the daytime.
