    Cascadian filter replacement

    I received my Cascadian filter replacement several months before I needed it. The scheduling got altered, I think, because Cascadian revamped their website and I was asked to sign up again for the auto-refill program. Will try to modify the schedule on their website.

    Hi DR RDR,
    Thank you for the review. Sorry for any mix up, don't hesitate to contact us if you need any help.

    The well water is crystal clear, everyone enjoys the taste and my laundry is clean!
    I already recommend this product and system to my neighbor and friends.

    Hi David, that's why we're in business, to help everyone to enjoy their water. And thank you for recommending Cascadian to friends and neighbors, that's the highest complement we can get.
