Product review (1 stars): Big mistake
I purchased these filters hoping they would work and that was a major mistake. I got them for my humidifier and when they came in I was confused because they say for vacuum. I even checked my order to see if I ordered the wrong thing but the description is for a humidifier. I then thought my humidifier was broken because I could not get the humidity in my room above 21 ( bloody noses and static what a pain). I decided to go to the store today and purchase filters just to see if indeed it is the unit but now it is working just fine. I changed those filters several times they just do not work properly. Very expensive lesson. Would have given it no stars but it has to have a rating.
