does the Hewelth UVClean work with tap water or only bottled?

Tap water is totally fine for the UV part to work, since it’s really about zapping whatever is already in the bottle. The one thing I’d keep in mind is that it isn’t doing anything about minerals or taste, so if your sink water has a weird flavor, you’ll still taste it. I just use mine with regular tap and it does the job for keeping the bottle from getting funky.

I’ve been using mine straight from the tap since I got it a few months back. Both at home and when I’m at work, I just fill it up under the sink and hit the button. I never really thought about it needing anything special because the whole point for me was just keeping the bottle from getting funky, not turning tap water into some lab-grade pure thing.

The way I see it, the UV part is doing its job on whatever is already in the water and on the bottle walls. If you’re on city water that’s already treated, there’s not much in there to begin with. I noticed pretty quickly that the bottle doesn’t get that weird smell if I leave it in my car for a day, which used to happen with my old plastic bottle all the time. That alone was worth it for me.

I’d say go for it if you’re just using regular tap water. It’s not like the bottle knows or cares where the water came from. The only thing I’d keep in mind is that it’s not a filter, so if your sink water tastes like chlorine or has sediment, you’ll still taste that. But for basic everyday use, tap water is totally fine. I haven’t bought a single bottle of water since I got mine.

I think the tap water thing gets overblown sometimes. The UV light doesn’t really care where the water came from, it just does its thing to whatever is in the bottle. I’ve filled mine from all sorts of places, kitchen sink, bathroom taps at work, even a weird outdoor fountain once when I forgot my bottle at home and bought a cheap one instead. Never had an issue.

The way I see it, the bottle is more about keeping itself clean than turning regular water into something fancy. If you’re already fine drinking your tap water straight from the glass, then putting it in this bottle isn’t going to change anything except maybe making sure the bottle doesn’t get funky after a few days of use. That’s mostly what I bought it for anyway, not because I was worried about my sink water.

I just use regular sink water and it’s been fine so far.

I’ve used mine with sink water since I got it and haven’t had any issues. The UV part just zaps whatever’s in there, so it doesn’t really matter if it’s tap or bottled. Main thing is it keeps the bottle from getting that funky smell after a day or two. That alone is worth it for me.

Tap water is fine. The UV light is just killing bacteria in the bottle, it doesn’t care if you filled it from a sink or a store. I’ve been using mine with regular faucet water for a couple months now and it does what it says. No reason to buy bottled water just for this thing.

I think you’re overcomplicating it a bit. The UV part is just doing its own thing inside the bottle, it doesn’t know or care where the water came from. I’ve filled mine from all sorts of places, random fountains at the park, the weird sink at my gym, whatever, and it still does the job.

Tap water works, but keep in mind it’s not actually filtering anything. If your sink water has heavy metals or chemicals, those are staying in there. UV just kills bacteria. Fine for most city tap water, but if you’re on well water or something sketchy, that’s a different story.

I’ve used mine with sink water since I got it, both at home and at the gym. Never had a problem with the UV part doing its thing. The only thing I’d keep in mind is that it’s not going to change how the water tastes or remove anything weird that’s already in your tap water. If your water’s fine to drink as is, then the bottle’s just adding an extra layer on top. If you’re on well water or something with a funky mineral taste, you’re still going to taste that. So I’d say it works, but don’t expect it to make bad tap water taste better. It’s more about keeping the bottle itself from getting gross after a few days of use.
