Product review (5 stars): Humidifier Filters
Sears no longer carries these, so I found on Amazon and ordered for my parents. The price was much better than what they paid at Sears and it was a bonus they received an extra set that they'll have on hand when they need to replace them.  Make no mistake that they aren't easy for seniors to put on, but that's the way they humidifier was made, and thank goodness my daughter and her friend were around to put these on for my folk's humidifier.
