The OEM filter we bought is a funk that won't wash off. I ordered these as a replacement. The price is certainly very fair compared to OEM parts. I was very impressed how closely they resembled the original filter. They are also washable. I put one in and it fit perfectly. The vacuum cleaner works again, the smell is gone. I see no reason to overpay for the brand.
