I never tried drinking tap water in my house before the filter. I just bought water bottles and drank it. so I don’t know the taste difference. Buttt I do tell the difference when hot water mixes with the cold water because the filter is hooked up only to the cold water.
Hmm Honestly I don’t really remember what the water tasted like right after install, but I do remember It did taste strange. So I only used the filtered water to wash the dishes for the first couple days and started to drink it after.
