Filter fit well and easy to install. However the small connector for pipes doesn’t fit my unit ( water filter system purchased in Canada). Water tastes great and no more calcium buildup deposit in kettle
I still would give 5 star for quick delivery and price.

Great product

Easy to install.Water tastes great.Will probably start a routine and swap out filters every 6 months or so.
