Review on Highly Efficient Replacement Filter for Professional Lift Away Models by Bill Dahl

I changed the filters on my Shark using one of the two kits in this kit. The old one was about four years old. The vacuum cleaner worked well before they were replaced, but worked surprisingly well after that. To test, I vacuumed the carpeted area of the house before the filter change, then vacuumed the same area after the filter change and the cleaner was filled with a few inches of fine dust that it was able to pull out of the carpet once. absorption increased. I'm sure vacuuming with new filters will help with allergies. Considering the price, it is worth changing the filters frequently.
