Product review (5 stars): Filter works fine
I bought this filter for my Essick MA0800 humidifier and, like others who have written reviews about securing filters, I was not able to find one at local stores.  The one I purchased from filters-now.com was about half the price of others I saw and it worked fine.  I did have to trim about 4" from the filter to have it fit in my humidifier, but that was no problem.

I'm glad I bought two of the filters, as these will probably get me through this winter season.  At $7.99 each, they weren't cheap, but Amazon had other similar filters at over twice the price.  Shipping was prompt and I received my filters, using standard shipping, 6 days after I placed my order.  Quite pleased with product, price, and service.
