Product review (3 stars): 3.25" circles.... :(
I couldn't find anywhere in the description what size they were and just hoped for the best buying these since when I choose the Vicks UV 99.999% Germ Free Humidifier these were on the recommendation page... I was WAY wrong... if you are getting it for the the Vicks machine like I have make sure you get the one that actually says VICK in the name (and yes for some reason the smaller ones are cheaper that we need for the Vicks machine)..... all in all though they are made properly and will work for whatever machine, Im sure, they are meant for. So wish the description can be updated with actual measurements so no other person does what I did
