The bubble works phenomenally. Fan housing has an efficient foam filter. Filtered air keeps the unit inflated. What I really like about it is the constant air flow over the bike. 12 years and I had one fan failure at 6 years.. Bought a replacement fan on fleabay for nine bucks. Percolating right along 24/7Nice ride. Good luck with the sale. How do you like you're storage bubble? I been thinking about getting one for a dune buggy I built last winter and my bike.
