This is the first Amazon review I have written but after reading some of the negative reviews on this item, I had to add my 2 cents worth. Although expensive, the price here is still $3 less than I found anywhere else (stores and the internet). This is the lowest price I have found these bags selling for (you get 3 bags in the pac). If you have allergies, you will appreciate spending a little more for a bag that really does trap the fine dust particles, etc. I do not have a problem installing or removing the bag. No dust escapes when I remove the bag.
