I was skeptical at first, but this filter cap really works. Water tastes noticeably cleaner, and it fits my 17oz bottle perfectly. Easy to install and clean. Great value for the price.
Filters well and fits fine, but the flow is a bit slow. Not a big deal for me. Happy with the purchase.
This cap has completely changed my water bottle game. No more plastic bottles, no more funky taste. The filter lasts a long time and the protective cap is a nice touch. I've already ordered more for friends and family. Highly recommend!
It's okay, not amazing. The filter does help with taste a bit, but I expected more. Also, it's a bit pricey for what it is.
Awesome!
I bought this for my S'well bottle and it's a nice upgrade. The water tastes fresher, and I like that I'm reducing plastic waste. The cap is durable and the protective cap keeps it clean. Would have given 5 stars but the initial flow was a little slow until I got used to it.
I really wanted to like this filter cap, but it just didn't work for me. The water flow was too slow and the filter seemed to make the water taste weird. I tried cleaning it and following instructions, but nothing helped. I've gone back to my regular cap and will stick with my Brita filter at home.
