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.
I have the dyson cordless v8, the suction returned to my vacuum but the pre-filter does not properly seal. On the upside the filters did eliminate the odor problem. I wish it did it's job and stayed in play and created a good seal. I am extremely allergic to the fine dust around me and would not want the filters to do the opposite for me.
Fake took dyson to the store under warranty still but not close to us because it was having issues my husband tried to order parts to avoid having to make the drive x 2 to drop and pick up but it continued to have trouble. The tech said this filter doesn’t work and it’s not a real dyson product she said it should say dyson on the outside and the inside which most only say on the outside if fake
The rubber seal is bent and has imperfections. You can put it in but it’s a little loose fit than the original, I honestly don't know if will do the job right. I also don’t know what will happen to the cheap material if you wash it. If you’re using it for 6 months or so buy the original.
I liked the power to clean when I have it. So very frustrating how after 10-15 minutes at most NO power. Handy to get in and under places. But- where can I get a battery pack so I can vacuum my house in regular time. This is crazy to vacuum for such a short time and then charge it for an hour. This took me hours to clean my house.
