Shark NP319 & NP320 2 Foam & 2 Felt Filters, Part # XFF318
Works fine and for a good price. Wal-Mart sells the vacuum cleaner and does not sell the filters for it. You can rinse the filter out multiple times, but eventually they start to show excessive wear. I can use my vacuum again, now. Fit the Lift Away portable vac by Shark perfectly. I did not get the full vac just the portable part as I only have throw rugs. So, it fits my model as claimed in ad. I am happy with the product.
