I wasn't aware of this when I bought these filters but Watts no longer makes them. That's why I could only find generic versions. Long story short, these filters barely lasted 3 months in a house of 5, only using them for water and an ice maker in the fridge. The water now tastes worse than just the tap, so I'm not exactly sure what's going on. I guess if you calculate the costs it might even out eventually if you swap them out more often, but who wants to worry about that? I went to ebay and in fact there are people selling a stock of OEM watt filters, albeit at a higher price. This is something I will continue to do until supplies run out or are no longer available. At this point, a new filtration system is the only option.
