question:
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..
answer:
Good Review
