UNDER SINK VS. COUNTERTOP FILTERS: WHICH IS LESS HASSLE TO INSTALL?

I hear you on the countertop leaks—mine would always start dripping right after I thought I’d fixed it. But honestly, the under sink install was a bit intimidating for me at first. I had to borrow a wrench from my neighbor and spent way too long watching YouTube tutorials. Still, once it was in, I kinda forgot about it, which is nice. The countertop one was cheaper upfront, but replacing those little plastic cartridges all the time added up. Guess it’s a trade-off between hassle now or hassle later...

That’s exactly how it went for me too. The under sink install felt like a mini plumbing project—definitely not my favorite Saturday. But after that, I barely notice it’s there, and no more wiping up puddles from countertop leaks. I will say, the under sink filters I’ve used seem to last longer before needing a change, which is a bonus. The countertop ones are less scary to set up, but I got tired of the constant fiddling and cartridge swaps. Guess it depends if you want to deal with the hassle all at once or in little bits over time.

I get what you mean about the “mini plumbing project”—I was honestly a little nervous about messing something up under the sink.

Honestly, I was worried I’d mess something up too, but the under sink install wasn’t as bad as I thought. For me, the water flow stayed about the same, maybe just a tiny drop. Taste-wise, I actually liked the under sink filter better—felt a bit “cleaner,” if that makes sense. Could just be in my head, though...

Under sink filters definitely look more intimidating at first, but honestly, once you’ve done one, it’s not rocket science. I’ve put in a bunch over the years—sometimes for my own place, sometimes for tenants—and the biggest hassle is usually crawling around under the sink, not the plumbing itself. Countertop ones are easier to swap out, sure, but they always seem to get in the way or look clunky.

Did you have to drill into your pipes or did it just hook up with a T-valve? That’s where I see folks get nervous. As for water flow, yeah, there’s usually a slight drop but nothing major unless your pressure was already low. Taste is subjective, but I’ve had people swear they can tell the difference... then again, I’ve also seen folks drink straight from the garden hose and say it’s “refreshing,” so who knows.

Ever had any leaks after install? That’s my only gripe—if you don’t tighten things just right, you’ll find out the hard way.
