Harbor Freight blowers hardly need any weather protection, just a cheap tarp is all that's needed, just as long as cooling air to the motor isn't obstructed. At the moment have 3 blowers, the one in the basement stairwell exhausts right on the ground behind some shrubbery, the other 2 exhaust along side the garage wall about 3' off the ground. No filters. I've been exhausting this way for 18 years with no problems and no neighbor complaints (there's 5 homes within 100' of my exhausts)..
