We have noticed a significant decrease in our allergies and in the dust in our home.
Replacing the prefilters every 3 months is a breeze - you just unscrew the bottom, unwrap the old one and wrap the new one onto the HEPA filter. (We do it outside to reduce dust in our home).
The one issue I have with it is the noise. If you came for something quiet you might want to look elsewhere. The consistent sound of what I can only relate to a central vacuum system constantly running forced me to shut it down for the night, even on its lowest setting. I imagine that it's a sound I could get used to but for now I just run it during the day on low when I'm home and medium when I'm away. The high setting almost seems like overkill to the point where the air being thrown out I would image presses it down to the ground. Blow through a straw as hard as possible and you get the tone of what this thing sounds like, but louder. Another small problem would be the brightness of the fan speed light, it's quite bright in a dark room.
Back to the high note though. The bottom is held off the ground by 4 half inch thick soft rubber pads so the little vibration it does produce is dampened to the point where the room below me can't hear it running. The entire top of the unit comes off by turning a very large knob on the bottom at which point the entire top/grill assembly comes off and reveals the filters simply sitting on the base (Though I must add that the filter makes a perfect seal against both ends and the unit assembled pushes everything to where it should be) so maintenance is quite simple and based on how large that filter is, it doesn't have to be replaced often. To top it off, the room SMELLS different. The AIR in here is clean, and with many cats, that's new.
Overall, it's a keeper, just louder than I was lead to believe.
-purifies the air in large rooms quickly
-easy to maintain
-prefilter is inexpensive, and you can just vacuum it out
-low power usage
-quiet enough not to disturb while on low
-very noisy on high, but its to be expected its moving large amounts of air
-large, but that's to be expected with such a massive filter
For the video I filmed using my iPhone at 8' away and 3.5' off the ground. I also ran a sound meter to record db during operation. The room baseline was 44db (only central air running).
