This is a filter. Yes, it's a HEPA filter, but that doesn't change the fact that it's just paper, glue, plastic and silicone. The time to create it on the assembly line is similar to the cheap ones, and we're only talking 20 - 40 cents more in materials. Price them cheaper and more people will buy them.I know it's not the vendor's fault that the manufacturer has priced them so high, but it's irritating nonetheless.
