Review: excellent filter - My well water is crystal clear now. Previously I used a whole house pleated cartridge filter plus a brita filter for drinking water. The pleated filter lasted 2-3 months but I still needed the brita to remove the metallic taste from the faucet. When I switched to this carbon block filter, I no longer needed to filter my drinking water. I cant say yet how long this filter will last as I just started using it but I can say that the well water from my faucet is pristine with no noticeable drop in pressure. I had 2 water treatment companies tell me that I needed very expensive filtration and softener systems to get rid of rust stains and metallic taste in my water but I tried a "big blue" filter and this cartridge first and am completely satisfied.
Review: Excellent filter! - This filter is performing very well filtering the water. The filter I had before didn’t performed well and I could see sediment in the water. There is no bad odor and the water don’t taste bad, although I use my whirlpool refrigerator to drink water. So overall I think this filter is pretty good so far ! Will update this review in 5 months. Stay put!

### ⭐⭐⭐⭐⭐ Works well for bad smelling water and sediment.
*by D***H on September 14, 2020*

We really like this filter with the charcoal. It captured a lot of iron and sediment. We had bad smelling water and it cleared up within a day after installing this filter. I don’t think this will completely replace getting a whole house water system, but it doesn’t cost $3,500 either. I have to change this filter more often than one for just sediment to keep water from smelling and turning plumbing black. We’ll see how it goes for the next six months.
