After running this unit for just one week I've noticed a great reduction in dust from our fireplace which used to settle on everything. We have it sitting very close to our TV but it runs very quietly - even on high - and doesn't interfere with the volume on the TV.
The only reason I did not give it five stars is because it has a pre-filter I was unaware of which has to be replaced several times a year. At $15 each that could add up quickly. However, I purchased a smaller Honeywell unit for the bedroom which also has a pre-filter and the instructions say that it can be rinsed and air dried so I don't see why I can't do the same with this one.
All things considered, I'm very happy with this unit.
