A2O Water - Made in USA, Combo Special: Premium Performance Filter & Reusable Cleaning Cartridge- HGN Type (Please see product images to verify the filter type)

The media could not be loaded.  The filter did not fit my SD501. It wobbles and water leaked from under the filter all over my counter. I did not notice a major difference in this cleaning unit than the one that comes from the manufacturer, but I only got to try it once. The biggest disappointment was when I called the seller to get help and to no avail. Returning this item for a refund. I think I will just stick with what works. I tried.
