Product review (5 stars): ... second order of this product and I am very happy with it
This is my second order of this product and I am very happy with it.  It's convenient to order the two-pack, so that when I get the notification that it's time for a new filter I already have at least one on hand.  When I have used the second filter in the two-pack, I immediately order more, so that I never run out.

Highly recommended, and delivery is very speedy!
