I was disappointed with my experience from start to finish. I ordered one replacement filter and before receiving any shipping confirmation, I received daily marketing emails. I utilized the coupon from one email and ordered a second filter. Days later I had no shipping confirmation and started to suspect the website was a scam. Emailed asking what's up and was told the filters are on back order. Weeks later I receive one filter. Then a voicemail asking if I actually meant to order a second filter, and that they wouldn't ship the second until they heard back. But you sent me a coupon so why is it so strange that I ordered a second? So I responded that yes I ordered a second, and I was told it's still ok back order and will be a few more weeks. Eventually it arrived. But I never received any shipping confirmation or tracking info on either order so I never knew when it was coming. I will not be purchasing from here again.
