Quick shipping, good product

Got the Ersatzfilter for my system. Ordered it Friday, arrived Tuesday. Packed well. Simple replacement process. Filter works as expected.

Good filter, easy install

I bought a Trinkwasserfilter last month. It was pretty straightforward to install in my kitchen, took me about 30 minutes. Water tastes a lot better now, I noticed it right away. Shipping was about a week to Ohio.

Quick question about discounts. I wanna get a filter system and some replacement cartridges. If I sign up for the newsletter, can I use that 10% off on everything in my cart, even the refills?

From what I remember when I got mine, usually those newsletter codes only work for the main hardware or starter kits, not the ongoing subscriptions or replacement filters. But worth a try, you enter it at checkout anyway.

I think they say on their site that discounts don't usually apply to subscriptions or refills. It's mostly for the initial filter unit.

Hey, thinking about grabbing one of these filters. Their tech sounds cool but is it actually legit? Like, some of these water filters just feel like snake oil sometimes. Wondering if anyone has real experience with it.

Yeah, totally legit! I got a starter kit a few months ago. The installation was pretty straightforward, and the water tastes noticeably cleaner. They have a bunch of scientific papers linked on their site too if you want to dig into that kinda thing.

I was skeptical too, but my buddy works in environmental science and he said their molecular coating tech is actually pretty advanced. Not just another carbon filter, afaik. Been using mine for a few weeks, so far so good. My old filter just wasn't cutting it.
