Product review (5 stars): Humidifiers are WAY UNDERRATED! A must have for me.
Based upon my past experience with other brands of humidifiers, I would never again even try a "generic" replacement filter. This filter has served me for three past winters and this is the fourth. The advantages of the Essick humidifier include ELIMINATION of those mysterious "paper cut-like" cracks in the fingertips that hurt far more than they would appear to! Static electric shocks vanish. I buy new filters every November and discard them around April.

More importantly people, if you live in an apartment (renters) rather than to own a home (in which you should install a humidifier on your furnace), I cannot extol the virtues and benefits of a humidifier. And my Essick ED11 humidifier will NEVER be abandoned from November through March!

It isn't very "pretty", but WHEN, as I know it will, wears out, I WILL REPLACE IT WITH ANOTHER ONE!
