This thing is bulky and ugly but it works SO well. I bought it after moving to a house with well water and noticing discolouration, dryness, and breakage in my hair which I’d never had before. My skin was also becoming dry and itchy. I noticed the difference with this filter immediately. The water smell disappeared, my hair felt silky smooth, and so did my skin. When I needed a replacement filter after a few months, I opted to I try the Jolie filter which has celebrity endorsements and Instagram ads everywhere, because it’s much sleeker and had great reviews too. The Jolie filter is actually useless in comparison to this one, so I’m going back to Aquasana. Great product!

Excellent product, MADE IN THE USA -- it matters, and most importantly works well! We can absolutely feel the difference once a new filter is installed -- the water is softer and not nearly as abrasive. Skin and hair do better, this really does change the way you shower, and it's also very affordable and worth every penny! Also, as long as it's installed properly (which is not difficult), you will not have any "messes" to deal with -- and we have had this for years with no issues. The only downside is that it really does not be replaced more often than the recommended 5 months. I would say every 3-4 months. Still absolutely worth it. PROS: +Works well, removes most of the harsh chlorine in your water. +Skin and hair feel much better. +Affordable. +MADE IN THE USA CONS: -none really, just make sure to replace it every 3-4 months depending on usage

I have used this product for many years and have found it to be of top quality. My skin feels clean after having removed all the toxins that are in our water now.

This works great, just as described. It is not a water softener. It's a chlorine filter. Like it says. All these reviews about the high TDS readings are beyond ignorant. A water softener system is huge and costs thousands of dollars. This filter helps reduce chemicals from processed city water. Like it says.
