If you're going to go through hassle of installing an RO system, at least get 4 stages to include the sediment filter. I have a 5 stage system (no UV light) and it's great, have had it for about 7 years now and parts to eventually fail so I had to replace the tank and the housing for the filters, but still worth it to have excellent water (I use a TDS meter and the city water is about 210-220 where after the RO system, I'm getting 12-14 TDS which is cleaner than bottle water). We use RO water for cooking, coffee, etc and everything taste great.
Lol, illegal. That term is used so liberally. It's against the building codes in some places. As a homeowner one has the right to whatever you want to do within your own home, but at your own risk.

However, if a licensed plumber or contractor were to do something against the code, then they are in violation and may lose their license.
Read the reviews on Costco, people complaining about the availability and price of filters and there seems to be leaking issues down the road.

noob question, I have been wanting to have a RO system but the only opening by the sink is taken up by the dishwasher air gap. Is there any way to install a RO system without having to drill a new hole on the granite countertop? I asked a plumber and he said "no" and strongly advice against forgoing the airgap for the dishwasher.

Removal of the air gap is illegal in most areas. Drill another hole or get a countertop RO

Evaluate your options. There are some dishwashers that don't require it. Or at least in new home construction I have not seen the air gaps. Some newer model dishwashers may have another system in place.

I'll say this, getting an undersink ro system was one of the best moves i made for first world problems. Its so nice to know you have clean water but also relatively effortless after the install. Getting a tile company to come out and drill a hole can't cost more than a hundred bucks and might even be less. I'd just make sure they are bonded insured etc and accept liability if they mess it up. Maybe they won't bother but it can't hurt to ask. When its all said and done if you had to diy you own hole its not incredibly complicated but obviously the risks are large. The large boring type bits with diamond edges are far more forgiving than your standard drill bit most people think of.

Some new dishwashers don't need an air gap, e.g. Bosch, but some city codes still do. I'd say check the installation instructions of your dishwasher to see if it shows an installation without an air gap.

I work at a water store and remove generic brand ones all the time to install ours (pentair,hydrotech) beware of filters costing insane amount of $$$

Our filters for our units cost about 50 bucks yearly for 3

Also this might not be a 1/1 system meaning you'll waste more water (edit: I see it says it's a 1:1 system)

I get 400-500 TDS before the filter Frown
Man infrastructure sucks here....

I'd pay extra for the 5-stage, you' use this everyday and the water goes into your body.....
I use the ispring 5 stage for ~ $190
