Product review (1 stars): but then it just became limp and useless! I bought a 4-pack and it's too late ...
DON"T PURCHASE! I bought these filters in summer and just tried to install in my Sears/Emerson humidifier. They are very thin and the shape wasn't right, so I thought if I wet it a little I could shape it to fit, but then it just became limp and useless! I bought a 4-pack and it's too late to return, so I'd advise you to not purchase these but spend your money on the proper filter. A cheap knock-off and $42 thrown out!
