              Product is good but packaging/delivery very poor.
              My filters came damaged - box pushed in at corners.
              Very disappointed.

                We just started on our second year using this product. It works great, and you can't beat the quality for the price! We've compared the pricing to our local big-box stores, and these are a much better value. What I love the most is the email I get every three months reminding me to change it out. That helps a LOT! We will continue to use this product for years to come! Thanks you!

                    Nice not to have to go to a Box store and listen to the false greetings, pay tax, and generally waste time and fuel.
