I don't know why it took me so long to find these filters, I think because I thought it would cost a fortune! I've been dabbling in washing the vacuum that came with the Dyson car and boat vacuum. If you wash it, you have to wait for it to dry and you lose the vacuum potential for the day. Now I have everything at hand and I can just go, go, go! I can't tell them apart from Dyson's, they fit perfectly and look the same. I highly recommend keeping them handy for those with a vacuum.
