[EX Q]: I've had these filters for about a month. I can notice an improvement in air quality, but no changes regarding our overall health. However, we use the filter everyday, so it's not like we're breathing cleaner air. This isn't to say that there aren't other better ways of providing clean air, though. Still, it seems worth it and we love being able to feel good knowing that we're doing something healthy with our money when using this..
[EX A]: Good Review

[EX Q]: After going through 2 sets of these I have thrown them in the garbage. We used all 4 lenses and could not make out what was on them. I can find nothing sharp when looking at my screen. Total waste of money. Bought another brand this weekend to replace these. This is a piece of junk that would be OK if they were 5 bucks. Not recommended. One star for Amazon Prime. As long as you get free shipping, go ahead & try it out. No hassle.
[EX A]: Bad review

[EX Q]: This unit worked fine for six months. Just now the LCD goes blank, no picture and will not come back on. The other features operate just fine, as long as you hold down the on button until it comes back! For some inexplicable reason every time I turn this player off my computer loses the connection to the internet. What a waste of money! Don't make my mistake. Buy one from a company that stands behind its products. You can't get any worse.
