Great product awesome price

Works as intended and sticks well

the self adhesive borders on the discs makes placing them pretty easy

Very satisfied

Excellent FAE Exchange, Easy to Replace, Great Price



I find these are super easy to use and replace. I do not have to worry about FAE and can use a humidifier either internal or external and not worry about the filter disks clogging or not allowing fresh air in. I highly recommend this product.
