Query: Very Reliable

I know a lot of folks struggle with the right thing to purchase and I just want you to know that I have had this item for nearly 10 years and it has run at the highest setting non stop. And it still works! There was a "brown spot" that appeared after about 6-7 years near where the led lights are at but it hasn't affected anything. Looks like I went a while without changing the filter and the LED lights got hot. I'm just delighted this thing has lasted this many years! At this point it's just bragging rights. I hope the rest of you experience the same as I have with this Air Cleaner.
