Why did you tell me that I need a hepa filter when I asked you about foam rubber filters? I have spare hepa filters. I need the foam rubber one.
Foam filter is not available on its on. You will have to buy this DCF9 filter kit which has the hepa filter and the foam filter on it. https://www.ezvacuum.com/eureka-dcf9-dust-cup-filter-74482-dcf9-genuine-p-564.html
