I have a Shark TruePet Lift Away. Bought this 2 1/2 months ago wanted a second set of filters so I can wash my filters when they get dirty. This set fits perfectly. The large round filter is exactly the same size as my original, the flat filter is a bit thinner than the original, but the original was washed before I looked at it so that might make a difference. Today I'm going to vacuum the house (not the basement) and my filters will be trained! Dog hair, dirt, dust, cobwebs. At least spring. I'll add an update after I've used the filters enough to wash them. I am attaching a photo of how my native filters were washed. For the money they seem like a good choice.
