Do you have a link? I can't find one at that price that also includes the filter (filters are typically ~$100).

My mistake, I did not realize the Walmart link included an extra filter

I did more research. I believe the Walmart link only includes one G3 CB filter (normally worth ~$30), not the 3 filter bundle needed.

I'm thinking about installing this next to my refrigerator. What T fitting will I need to use the existing refrigerator water outlet? Image attached.

You need a drain line for the waste water to go.

Waterdrop undersink systems use a 3/8" supply line. I was able to convert a 1/4" T for an icemaker to a 3/8" with this fitting:

As someone else mentioned, you'll also need a place to connect a drain line for the waste water this produces as well as for periodic back-flushing for clearing the RO membrane.
