I was think I could build my own air filtration system using an old vacuum cleaner. The one I have has a speed rating of 300 to 1000 CFM. I would make the box out of wood and buy the filters. I think I put the whole thing together for about $50 to $75.
I'd like members input on whether this is a good project or it just won't work.

Thanks for you input

Hi, part introduction and part answer. My names Lee and fairly new, this is my first post but I did something similar 7-8 months, found a squirrel cage fan ~750cfm for $30 picked up some furnace filters then picked up a 1 hour timer($30) and the rest was just scraps of plywood and an old extension cord, works really well

Thanks Lee, if I don't fine a Air Filtration unit on craigslist in the area, I'm going to try using my vacuum cleaner. The unit has everything I need except the filters.

The only thing I would worry about with a vacuum cleaner motor is the duty cycle rating. I don't know how long the motors are designed to run.

I have a home built unit using an old air handler motor. It's too big of a fan without having some sort of exhaust ducting on it to choke the airflow. It worked OK, but it works better now as a circulating fan on the really muggy, humid days. I have a handful of electrostatic air filters that do a great job of catching dust and are easy to clean. The bracket with one screw pops off and I swap out filters and clean a bunch at once.

I picked up a Jet ambient air cleaner off of craigslist for cheap and it works great. It is smaller, quieter, has 3 speeds and auto shut-off.

Remember you can find HEPA filters used for very little money, such as a Honeywell with a high flow rating. These filters are made for the exact purpose of cleaning fine particulates from the air and used will run $20-$25. Compare this to a Sears HEPA filter cartridge for a shop vac costing around $45 and it's no contest.
