      Thanks for the review. Sorry to hear you've had issue finding replacement filters. Due to unprecedented growth we did run out of inventory for a few months. Everything is back in stock now, but if you ever have issues again, give us a call and we might be able to help locate another dealer or offer filters ourselves at a more competitive price then you find on our website.blueair
