Review on Powerful Dirt Devil F4 Scorpion Cordless HV Filter for Superior Cleaning by Heather Davis

I was skeptical to buy them as initial reviews said it wasn't a real deal. The new reviews are getting better, so I thought I'd give it a try. I'm glad I did. These were the original Dirt Devil F4 filters and were perfect for my portable vacuum. They came in the original Dirt Devil packaging. Much cheaper than buying in store if you can find them. You don't have to change them very often if you regularly maintain your old device. These should last a few more years. The vacuum cleaner itself is likely to fail sooner.
