Excellent value for money. My Neato runs around the house on a daily basis picking up a lot of dust and pet hair and these filters do a great job of keeping the little vacuum cleaner from blowing them out the tailpipe. The filter material makes it easy for me to wash and reuse them when I want to freshen them up. I used vinegar diluted with water and detergent in a spray bottle with a small brush to clean them. Just let them dry and use them elsewhere.
