Product review (5 stars): This filter was hard to find, but worth every penny once found!
I never seem to find filters for humidifiers that are just a few years old.  Seems like the manufactures change their filters with each "new" humidifiers.  They'll only stock the current year's filter and if you're lucky, the previous year's.  I'm not gonna buy a new humidifier every year since the one I use work perfectly fine.  Thank god for Amazon.  I'd be up (bleep) creek if they didn't have so many connections.  Your filters cost even less than they did in the FEW stores I could find them in, which btw were many miles out of my way.  They work out to be cheaper to have them shipped to me (free with amazon prime) than driving outta my way to get an inexpensive, but needed product.  Thank you, Amazon!
