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..

A: Good Review

Q: Item took long time with standard shipping but price was right. Works perfectly and no problems even after 3 months. Hope it stays like that. Good product! Thanks Amazon!

Q: This is a good looking coffee maker but the lid did not seat properly and always tipped over when placed on top. It kept overflowing making one of many trips to clean up. There was no way that I could pour with out spilling coffee. Not recommended. Very messy. Bought a stainless steel pot at Walmart. Much better! Even though Mr. Coffee's coffee machine looks great it leaves much to be desired. The company should stick to marketing their own products.
