Don’t just take our word for it

"This filter was much needed for the water in my area of NJ. I can already feel a difference with my hair and skin. It is as if there is less build up. This filters design makes it easy to see when the filter needs replacing and that also assures you that it's working. It is also the ONLY filter I could find that filters PFAS in shower water, and trust me I did endless research! DO NOT HESITATE TO BUY! Clean water is SO important for our overall health."

"Hey, I was a bit doubtful at first, but I've been using this shower head filter for a few weeks now, and it's made a real difference! The water quality is so much better. I'm new to shower filters, but this one is my favorite by far. It's helped with my dry, itchy skin after showering. And it was super easy to install. If you've never tried a water filter for your shower, you should give this one a try. You won't be disappointed!"

"The filters collect a ton of sediment and other impurities. I totally feel the difference on my skin and hair. And, an added bonus is that I don't have to clean the shower stall as much - that is how good the filter is at doing its job!"
