Model 500 by Carmella Discianno (Chicago Il US)
I originally ordered the wrong model number(400). However, I contacted one of your representative and replaced it with the correct number (500). Within 2 weeks I had the correct model and I was able to install the filter and the new plastic holder very easily. I was very pleased with the service.
