We actually ended up returning it within the return window bc there was an issue tech support could not help us resolve quick enough, so returned while that was still an option. We meant to get a new one but never ended up and now do no have the same need. We did use it at an event and found it effective (as measured by its own sensor, which was a pretty sweet device on its own), but the clean air output is limited to being very near the device. In all, a great device for pouting directly at you on a desk or for travel. But, no, we did not have it long enough to notice how the battery lasts over time, to change the filter, or to see if there were any other noises.
Any updates after 5 months? Battery life ok, any weird noises? Replace the filter yet?
