I purchased Aquasana-4000 water filter, but it doesn’t fit to the faucet. What else should I buy? Any nipples? What type? Where to buy online?
Thank you in advance.

AQ-4000 is a countertop designed to fit a standard faucet. In fact, Aquasana designed this model so you can either use it as a countertop or as an undersink filter. So, if it doesn’t fit your faucet, you can buy the converter so you can use it as undersink.
You can find out more at http://www.waterfilters-camping-water-purifier.com/aquasana-water-filter.html . Aquasana has about seven different types of designer faucets you can choose from.
Hope this helps.
I ran into the same problem. I looked at every single faucet at Home Depot and not one would accommodate the AQ-4000 or the included adaptors. I think this is a serious issue for Aquasana.
