Product review (4 stars): Thinner backing but overall satisifed
These fit right into my current humidifier easily. Not ready to fire them up just yet as it is July and already humid here in Upstate NY. They are nearly as thick as the more expensive ones they are replacing and the lining or backing is a little thinner but they stand up rigidly on their own even without the clips. I took pictures to show the difference in backing and thickness between these replacement wicks and the more expensive ones I am tossing. Satisfied based on overall quality.
I purchased the humidifier wicks at a discount in exchange for my honest review. The thoughts and feelings expressed above are my own from my own experience. I hope that my review and photos are helpful to others.
