Best Air Purifier Report 2019

Testing Method

Testing is conducted in a 12x18 sealed isolated room.  To test the effectiveness of the air purifier we inject cigarette smoke and dust into the room through a tube and measure how much pollutants get removed from the air.  We use a machine that analyzes the particles in the air and measure the concentration change over a 15 minute period.  

Noise level is measured in decibel meter at ear level 4 feet from the air purifier.

Conway AP-1512HH Mighty Review

After running tests in multiple testing enviroments (12x18 sealed room, NYC apartment, Wirecutter LA Office Room) the Conway Mighty proves to be one of the best all around air purifiers for most people.  Also its low upfront cost and low ongoing maitenance costs make it more affordable than some of its competitors.  

During 1 test the Conway Mighty reduced airborne particulate pollution in a 200 sq ft bedroom by 99% in 35 minutes.  In a room 4 x the size of a bedroom it took 1 hour to reduce 70% of particulate pollution.  

The filters on the Conway last a long time.  We did a test comparing brand new filter vs used filter that had been running 24/7 for a year.  And the used filter still cleaned the air as well as the brand new filter.  Meaning you can go longer between having to replace the filter than that of normal air purifiers.
