Query: Not for everyday usage as machine just won't hold up.

I am a chronic allergy sufferer. I use this machine daily and when it works, it works great. However, I am on my second unit now (first one lasting about a year) and this one is dead in less than 7 months. The motors in these pumps just don't hold up. They burn up and lock up regardless of any type of regular maintenance the instructions tell you to do. To be short, if you're going to use it daily, use a different brand as this one won't hold up.
