[This review was collected as part of a promotion.] I love that this can be used under the kitchen sink or a normal faucet. It was easy to install as someone who has changed shower heads before and is more handy with other parts of the house. It took more time clearing out a spot for it than to install it and I love having filtered water to fill up my pots for cooking now.. Jacquelines. Fri Mar 27 2026
