Product review (1 stars): Not meant for Vicks Starry Night Humidifier.
I wish I had a good experience with this filter. I've recently purchased the Vick's Starry Night Humidifier, which came with its own filter for the first use. At first, I thought it looked flimsy and cheap, and expected for it to only last a week or two. However, it lasted me for a month. When I threw it away, there was nothing even wrong with it. It worked perfectly fine while I used it.

With this filter... No thank you. I purchased it from a local corner. When I opened it, I was impressed by how thick it was. It looked a lot more durable than the previous filter... The smell, however, was disgusting; my room smelled like it after the first two uses. I continued to use it in hopes that the smell would subside... I was wrong. I have been using this filter for a week and a half, and it's already beginning to grow mold-- a problem I didn't have with the previous filter. I clean my humidifier once a week with vinegar, and I always soak the filter in cold water before using my humidifier (worked great for my first filter...). I also noticed how quickly it would get warm. One factor could have been my humidifier. The filter was very big, which left very little room left in my humidifier.

Since I don't have any experience with another humidifier, I can't say it won't work great with different humidifier models. Not sure if the smell will change though.
