The pre filter does not fit- this product is a knock off.
July 29, 2019
I bought this hoping it was a suitable replacement for my Dyson. The pre filter does not seal and in fact fits so poorly it actually falls out. I have no way to test the post portion, the Hepa art of this filter but my guess is it is just as bad. The only thing I can say about the post filter is that it did actually fit.
