CUSTOMER CAVEAT -- These are new and never used water filters, they are simply left over in inventory from a model change. NSA discontinued making the 50C in favor of the (also now antiquated) CT-2000 countertop filter. As such, both filters have now become obsolete, and further, NSA is no longer in the water filter business. ESD owner Steve Harrison is no longer affiliated in any with NSA, so these filters are sold here as "salvage inventory." We have been advised that NSA will no longer warranty the 50C as it is a discontinued model. However, ESD has such confidence in this great workhorse of a water filter that WE will offer the same 3-year pro-rated warranty as was offered by NSA. In short, these filters are as good as they were factory fresh, they just gathered a bit of dust on their boxes. We've dusted them off, marked them down to a VERY fetching CLEARANCE DISCOUNT SALE price. Do note that due to the "salvage" nature of these filters, all sales are final. Returns accepted only in the event of shipping damage (must be documented with the carrier as damaged in shipping) or for a critical malfunction at onset of usage. Do also understand that a botched installation (attachment of the diverter valve to the faucet, the hose to the diverter valve, or the hose to the filter) would not constitute a malfunction. In short, if you simply decide you didn't want this filter after all, your best bet would be to sell it locally (garage/rummage sale) as the actual retail price on this filter was $179.00 and it's worth every cent of that.
