Faucet Mount Water Filter place to find the best faucet mount water filter offers and deals

Kitchen Faucet Quick Disconnect?

I just bought a Edgestar portable dishwasher for our home. This counter top dishwasher connects to our kitchen faucet with a quick connector. I also have a faucet mounted water filter. Where can I find a quick connector for the water filter so that I can easily switch between the water filter and the dishwasher?
The quick connectors that I have found have a course thread on the female end that connects to the water filter. I need one that is threaded the same as the faucet.
