This is an air cleaner that I built. It was surprisingly easy to put together and everything can be found at a local home center for under $100. I used a attic fan that moves 1600 cfm and three 1” air filters which I change every few months. Instead of using an on/off switch I used a 60 minute timer so I can leave it running when I do to clean up the air. I added three filters to the intake side. I vacuum the outside one off three or four times before I pull it off and then move the other two back with a new one to be added on the inside. I have am averaging only 3 filters per year. I purchased the attic fan from Home Depot. It is a Broan 1600 CFM Power Gable Mount Attic Ventilator. The current price on it is $99.00 which is up from $78 Two years ago. The noise level was very low out of the box, but I added some rubber spacers between the fan and the box, and also between the ceiling and the top mounts of the box to reduce even further. It runs very quiet which is nice because I let it run whenever I am in the shop.

Tym….Nice build. A buddy of mine built a similar air cleaner and found that taking out the first filter in line and moving the next two up one notch increased the life of the filters and still did a great job.

Indeed. A nice build. I’m procrastinating my way to building a box fan one.

That looks nice Tym. Here’s a thought…

I bought this wireless switch and it works great. I have used it to turn on/off a box fan with a filter taped to it! Currently I am using it to start/stop my shop vac which is hooked up to a Dust deputy. Sure makes it easy to operate a piece of equipment that is hard to get to.

An alternative to a timer or switch is a motion sensing switch with a time out when it senses no motion. Depend on how loud it is and if its needed all the time, so maybe two switches in series or parallel depending on what functions you want, Motion Sensing, manual on/off, etc.

This is on my project short-list. If you don’t mind me asking, what brand/model fan did you purchase and do you think it worked out? How loud do you reckon it to be? Thanks!

Can you post a link to the Amazon fan you used?
