If only it was the proper size!! Way too big for my Honeywell - I did NOT get what I ordered!!! I ordered the Honeywell Replacement Pre-Filters - what I got was a huge piece of filter that I have to cut to fit...it is NOT the actual HONEYWELL replacement filters - defeats the purpose for allergy sufferers - in order to cut to the proper size you have to lay the old, dirty filter on top of the new, thick piece of garbage. This thick "filter" will not get rid of the allergens like Honeywell's original filter. Buyer beware!
