Product review (4 stars): Save $, great for Vicks Starry night or similar
I have a Vicks Starry night humidifier and needed replacement filters. I wasn't going to pay crazy prices in store for them. This from Accumulair was a great alternative! Not only that, cost saving when you buy a four pack - almost like getting 2 for free when buying from the store. It feels and seems of the same thickness and material. You will note that compared to the original filter (especially when used) it would seem much shorter but I wouldn't worry. It will expand and stretch when it becomes saturated with the water. It fits and the humidifier is ready for the dry heat air! Started with no odd smell. I am happy with this purchase and so will my infant.

UPDATE 3/11/15: So far so good with my first filter. Since this has been an unusually cold season, the humidifier has been getting a serious workout. I don't know if that makes a direct impact or not but it is worth a mention. These filter do seem to yellow slightly faster than the OEM. It doesn't seem to impact the performance noticably or create a smell so that's good. Perhaps it's a bit of lime too from possible hard water? Just thought I'd mention that detail. Would I buy it again? Considering the price per filter and performance....yes.
