The market is flooded with different air purifiers, making choosing the best air purifier for your needs challenging. In this comparison, I will make it easier for users who are in a dilemma whether to choose the Hamilton Beach True Air or the Medify Air MA-15 air purifier.
I will comprehensively compare their performance, noise levels, operating costs, and all their specifications.
The first thing I noticed when testing these two devices is that the Hamilton Beach looks old-fashioned, and I think it needs a refresh in design. In contrast, the Medify Air is a contemporary air purifier that would fit into any home decor.
The Hamilton Beach True Air is intended for rooms up to 160 sq. ft., while the Medify Air MA-15 can effectively purify rooms up to 138 sq. ft. Both air purifiers are able to clean the air 4.8 times within one hour in the recommended room sizes. Although the difference in coverage is not huge, in terms of all other characteristics, these two devices are totally different.
The Medify MA-15 uses three-stage filtration technology consisting of a pre-filter, a True HEPA filter, and an activated carbon filter. On the other hand, the Hamilton Beach True Air uses only one filter, and it’s HEPA-grade, which isn’t even True HEPA.
I suggest checking the table below for an in-depth comparison of the two devices’ specifications.
