Rent or buy?
Big-box stores lend a blower free with a 10–20 bag purchase, which covers most single-attic projects. Paid rentals run $80–$180 per day. Buying a small electric machine makes sense once you expect three or more attics.
What to look for
Hose length (100 ft minimum for a two-story house), hopper capacity, whether the machine runs on 110V household power or needs a generator, remote shutoff at the nozzle, and an agitator that handles compressed cellulose bricks without jamming.
- 110V electric for interior use — never run gas equipment in an attached garage
- Remote on/off at the nozzle saves a lot of shouting
- Two hoses coupled together beats one long stiff hose for stair corners

A stiff walk board or insulation stilts, depth rulers, a P100 respirator, disposable coveralls, a bright work light and a broom. These are the difference between a fast job and a miserable one.
