What size PEX on Water Filter?

Getting ready to do some re-routing of water lines in and out of water filter on my Micro Lite. I have the OE filter housing that uses the KW-1 filter element.

Not replacing the filter, just want to know what size PEX to buy before I dig in. Unable to get to the filter now and when I do I'd like to have things at hand so I don't have to make several trips to HD.

Anyone know? 3/8"? 1/2"?

I just looked at our camper. It looks like the pex itself is 1/2. What I did was screw a 1/2 pipe thread sleeve coupler to remove the filter housing. On one side when removing the filter I rotated the fitting in the pex. On the other side, once the first side is off I rotated the filter housing. Did the same thing installing the sleeve, rotated one fitting in the pex. No leaks in 2 years. You could just cut it out and use a push in fitting instead. Jay
