There seems to be a price discrepancy. I ordered this product at $31.99 each, but when it was delivered it was the same as a similar filter that is listed for $9.99. There are two different products shown at this site that are both called Honeywell HC-14 Filter E. In fact, they are the same product listed at two different prices. Do not buy the product shown in the ad because it is priced $22 more than it should be. Buy the one listed for $9.99. Get more detail about Honeywell Replacement Filter E (HC-14).
