Product review (5 stars): Works perfect for our Essick MA0800 humidifier
Since we purchased our humidifier we have been purchasing the filters from a local box store right away in the fall. Well this year we were a little slow in getting them picked up for the season. In searching around found this filter to be the most inexpensive so I took a chance and ordered. They arrived on promised and fit our humidifier without having to do any  trimming to get it to fit (when picking up in the box store we had to cut at least 2 inches to get it to fit). Will definitely order again in the fall.
