Product review (5 stars): This unit work's great for a small restaurant size
We Purchased the AI 210ss in 2012 and it worked for about Two month then stopped.  We contacted the customer service department and they sent a return label the same day.  It took about a month and they sent a us brand new unit that operated for three  years.  Then we decided that since they worked so well for us we purchased a new unit AI215ss just recently.  This unit work's great for a small restaurant size.  Air N Water definitely guarantees they're products and is timely.
