This is just one filter. I was disappointed with the purchase. The bag appears to be for more than one, perhaps three. Although it was the proper filter for my vacuum one cannot actually see the number of filters due to the packaging and folds in the bag shown.I paid the price for the apparent bag of filters that did not speciify the number of filters included and paid the same price for shipping resulting in the purchase costing twice the filter cost. Shame, Shame. The company should have specified that this was for one filter only. However since I was unable to find this filter elsewhere, I will keep it.
