Product review (4 stars): They work
They appear a little shorter then the one i have now. Other wise identical so hopefully they work well. The price was reasonable. I will update when I try them i still have one in it right now.

Updated: 1/23/17 these work fine in my germ free humidifer. The price is the best I could find. They do not have that blue thing that replacement filters had on them , that were causing actual mold issues for most people. I have had no issues using these. They arrive quickly.
