I ordered 2 and neither one worked at first. Eventually we got them both running by fiddling with the little wheel, at least we think that is what got each started as it took several attempts. Delivery also took longer than expected, but I dont know that it was the fault of Infinity and Beyond or carrier.

Hi Evamarie, thank you for updating your review. We’re glad to hear both filters are now working! It sounds like the impellers simply needed a little adjustment to get them moving initially. Your order was placed Thursday evening, shipped the following Monday, and was delivered Thursday. We appreciate your patience and are glad everything arrived safely and is now operating properly. If you ever need assistance with your equipment, please reach out to us directly. We’re always happy to help.
