88% found it quiet to operate; however, 12% experienced occasional noises
The device operates silently on low or night modes and is only audible if the room is completely quiet and your ear is next to it.
At low and medium speed, the noise levels are perfect and not noticeable unless the room is silent.
At level 4 HIGH, I noticed some noise, but it's not as bad as other systems I've used.
80% found the filters highly efficient; however, 20% experienced occasional issues with filter clogging or reduced effectiveness
The filters are of high quality, multi-stage and can easily suck up smoke, most smells and dust.
I found the Coway Airmega 400S to be super efficient with dual filters on each side and touted to have 99.99% efficiency down to 0.1 microns.
The purifier is not very efficient in eliminating odors because the filters do not have much carbon in them.
I need to clean the prefilter every other week due to the small intake hole.
74% liked its energy efficiency
At the lowest fan speed, this machine is very quiet and efficient for a bedroom of 2-300 SF.
I have personally measured the energy consumption of the AIRMEGA 300 air cleaner with LED Air Quality Light On and found it to be energy efficient.
70% appreciated its design
Attention to detail is evident in much of the design, down to even the braided nylon encased power cord.
The air purifier has a good design with magnetic catches, robust filter build and fit, great status display visible anywhere in the room, and an easy to use control panel.
I was impressed with the attention to detail in the design of the unit.
I have seen many air purifiers, but this one has a flawless design and is one of the best looking.

76% appreciated the air purifier's coverage area; however, 24% found it insufficient for larger rooms or complex layouts
In my living room, the purifier covers about 800 sq.ft of area.
I combined the air purifier with three GermGuardian floor standing air purifiers to cover my 3000+ sqft house.
At the highest speed, Airmega's published room coverage data allows me to calculate the maximum air flow as 416 cfm, which is a decent rate compared to other premium air filters.
Each purifier covers an area of about 900 SF and is effective in dealing with pet allergies.

The air purifier significantly improves air quality, especially for particulates and pollen.
I am satisfied with the air purifier's performance as it improved the air quality in my home.
After installing the air purifiers, I noticed that my wife is breathing easier and needs less inhaler medication.
