Review on Nispira Foam Filter Set - Compatible with Shark NV42 Deluxe Upright Vacuum Cleaner. Alternative to Part #XFF36. Suitable for UV402 UV410, NV36, NV36A, NV42, NV44, NV46, NV46C. 2 Sets. by Patrice Lippmann

We have a Shark NV42 Navigator and filters that are absolutely gross! I ordered replacement filters so we can clean one set and prime another so we can use the vacuum cleaner without delay. The filters arrived in a plastic bag in an envelope and looked the same as the ones in the vacuum except for the colour. There are no instructions in the box, but you can see which filter goes where. If you are unsure, consult the user manual. The new filters fit perfectly and the vacuum cleaner works like new!
