Cirkul フローフィルター

The carbon block inside does exactly what it says—my tap water tastes noticeably cleaner without that metallic chlorine edge. I’ve been using it for a couple weeks now and the flavor enhancement on the go is a nice bonus.

I was skeptical about a filter I could toss in my bottle, but the carbon core genuinely strips that pool-like chlorine taste out of tap water. Now I actually look forward to refilling at the gym fountain instead of buying plastic bottles.

The water tastes noticeably cleaner with this filter in my bottle—no more chlorine hitting my nose on the first sip. I've been using it daily for two weeks and the carbon still holds up well on flavoring my water on the go.
