## Customer Reviews

### ⭐⭐⭐⭐⭐ Good quality, good price
*by J***N on 29 November 2024*

Having tried several other brands I will probably stick with AquaHouse now. They work well and the price is good.

### ⭐⭐⭐⭐ Good value
*by M***O on 1 April 2024*

Appear to work as well as other makes.

### ⭐⭐⭐⭐⭐ These fit
*by F***O on 23 June 2025*

One of the problems I have with buying any kind of filter is fit. If they're just a few millimetres too long, you won't be able to tighten the housing correctly. I'm happy to say that these fit perfectly. I draw water from steel tanks, which can give my drinking water a funny taste. These carbon filters work as exactly as I'd expect and make my water potable.
