Good Call!!!You should be able to remove that screen section which should then give you access to the threads inside that faucet spout. Once you see these threads, you should be able to find an adapter possibly.
about pulling out the screen, hope ;Nailbiting there's some threads behind it 
Excellent idea, especially if any adapter can't be found for the faucet. I haf s terrible time finding an adapter to fit a sink where I use a python house system!Buy one of these and connect under the sink

I have to for the winter.Well,
I run my RO/DI unit off a faucet too. Not the most efficient way to run an RO/DI, but it works.
Maybe some needlenose pliers that could fit into those small grooves.That’s the thing....I’ve struggled to removed the screen section but I only tried using my fingers, no tools.
MOEN is the brandWho's the faucet manufacturer?
Squid,
I might want to go that route.
I thinking I'd get more water pressure than using the faucet. What's your thoughts?
I run one of these.Went to Home Depot and Lowe’s. Neither Store had 13/16” male adapter required to run the faucet adapter that I have.
