Get a 1/4 inch tube/hose long enough and route it to back of fridge. But in general your frige needs to be pretty close by so that you don't need to route the tube through walls or furnitures.

Non-powered membrane RO3's are 4 to 1 unless you have good pressure and add a "Permeate Pump" ($60 waist water pressure based pump) and that brings it to 1.25 to 1.
I use a Aquatec ERP-1000 (100GPD) they also make a Aquatec ERP-500 (50GPD) and I dont know anything about it but the neoFlo / Neo-Pure HEPP200 is rated for 200 GPD

Very cheap on Amazon as most Ro3s go.
But for $150 I would just get the higher quality APEC 7 stage (UV light) off Woot for $152

Add splitter and run one line to supplied faucet and one to your fridge. It all depends on your kitchen configuration and how far your fridge is from the sink. I installed the same system in my basement and ran 2 lines thru the floor since my fridge is on the opposite wall from my sink, and running water line would be difficult.

Bought this 6 stage on Amazon a while back! It's GREAT! Obviously, it's not a 0 TDS, but mine is right around 40 (SoCal hard water with softener).

I watched several YouTube videos and bought food grade o-ring lube for each filter o-ring and housing for longevity of the filter changes.

Also, my waste pipe was too big for the included bracket, so I ended up having to get a separate one available on Amazon!

Happy installing!

iSpring sells them on Amazon. Currently 3-year supply is $160 2-year $140. Both include membrane (which is not included in 1-year filter set). If you catch them on sale they are even cheaper (~$100 for 2 year supply)

I bought an extremely similar system from Amazon for $200 in July 2019. They system works flawlessly and it gets a lot of use every day. I priced out what it would cost for a full filter replacement and it is around $105 - and I just replaced them in July.

Just ordered this from Costco. My 7 year old RO system is pushing it, especially the rubber bladder that is inside the pressure tank is about end of life. So the extra $45 or so to purchase a new one, to be installed next year, is worth the peace of mind

No, no pump. I believe you need pump only when your supply line water pressure is low, or to reduce waste water.
