I love this new sink water filter. I had an old filter that attached directly t the faucet, and it was so ugly. This new filer fits under the sink, and no one even knows it is there. It is also much better quality than my previous one.

I added this water. It feels like nothing has changed, but I feel so much better knowing that I am not putting harmful chemicals into my body when I am drinking water. I feel like it has helped me become a healthier individual!

Once I reviewed this product I had no issues installing it. I thought I was going to have to call a friend over to help me, but I figured it out by myself by reading the manual. Such an easy machine with so many benefits! Why wouldn’t you get it?

Customers’ Reviews:

This water filter was so tiny and perfect for my smaller sink. I do not have that much space in the sink cabinet, but I still wanted the filter covered and out of the way. This product was perfect. I highly recommend it!

I am so happy to be drinking clean water. Knowing that I can fill up a glass of city tap water and be safe makes me feel healthy.

My Brita filter was taking up way too much space in the fridge, so my three roommates and I decided to try an under sink filter. Definitely one of the smarter decisions that we have made in our university years.
