Product review (1 stars): Poor Quality
These came in the correct box, but I find it hard to believe that they are true Essick filters! Two out of four fell apart upon normal removal from the box, but I put them in the humidifier anyway. I didn't measure them, but they are definitely smaller than the ones I buy from Home depot, even though it says it's the same measurements. This is night number one using them, and my humidifier is not putting moisture into the air like it should. Maybe these are old. Either way, I'm sending them back. I would rather pay $20 at Home Depot and get something that works, then pay $15 for a bad product! I've been an Amazon customer for years and bought many things, but this is the first time I've ever had to return a product for being cheap junk. I'm very disappointed with my purchase!
