Product review (3 stars): Product received not as described
Item description on Amazon.com is not what you will receive.  The filter you will receive is NOT "enclosed in a plastic frame that insures water flows through proper path for evaporation".  All you will receive is the filter pad and no plastic frame.  This same FRAMELESS filter can be bought from other sources for less money.  I paid more because I thought I was getting a filter WITH a plastic frame.  What I actually received is exactly described at: http://www.amazon.com/Solution-709-Aprilaire-Furnace-Humidifiers/dp/B000HJ958C/ref=pd_sim_sbs_hi_5
