Boxfan Ambient Air Filter Hack Revisited #2: New Tests and New Filters

06-27-2020 01:38 PM by clagwell | 2 comments »

Last year I acquired a Hot Wire Anemometer. I intended to do some dust collector testing with it but that didn’t work out. It seems a HWA is really a tool for HVAC work where the pressures and velocities are a lot lower. That should be perfect for testing a box fan filter. In order to get the measurement points away from the complex flow patterns near the fan and have a well defined area for the traverse I fabricated a test duct with the vertical traverse calibration points.

Boxfan Ambient Air Filter Hack Revisited #1: Seven years ago...

06-27-2020 12:00 PM by clagwell | 6 comments »

A few years ago I decided to try the trick of slapping a furnace filter on the back of a box fan to make an ambient air cleaner. I wasn’t at all happy with the performance. It seemed like the filter almost completely choked off the airflow. The filter clamps can hold up to three inches of filters but I could barely get any air through a single filter let alone two or three. Air flow rate is at least as important in an ambient air cleaner as filter efficiency so I really wan...

Dust Collection & Health Risks from Wood Dust

10-20-2019 01:00 PM by WoodshopTherapy | 2 comments »

I recently had a health scare about my lungs – everything is ok now, but it reminded me again why respirators, vacuums, dust collectors, and air cleaners are so important. I don’t see enough of this type of information on YouTube to educate woodworkers, so I invested hours of time making a video that I hope will help fellow woodworkers be more aware and invest in protecting their health. If you find it useful, please share it… I feel it’s an important message for a...

Shop Projects #1: Air Filter

10-02-2017 01:15 PM by BrettGoodermote | 2 comments »

One of the downsides to a small attic shop is the crazy amount of dust in the air. I have some windows I can open while it is nice out, but even that only has a limited effect. After browsing the internet I decided it was time to make an air cleaner. I did not want to make a major investment in a fan, and the typical box fan was just not powerful enough in my opinion. We use a Lasko Wind machine in the living room and bedroom and these fans are GREAT!! I happened to catch an end of the sea...

Shop air cleaner #1: The build

10-15-2016 07:42 AM by JSOvens | 5 comments »

A popular home-built shop accessory these days is a filtered shop air cleaner, of which I’ve had the privilege to see several designs. Whether floor standing or ceiling mounted, or using box fans or centrifugal blowers, they all have some things in common: they are fairly simple and inexpensive to build. My workshop is located in a tandem two-car garage, in rainy Vancouver, BC, Canada, thus it is not always feasible to leave my garage door open for long lengths of time (woodworking i...

work shop air filter.

09-13-2015 07:42 AM by fatman51 | 5 comments »

A couple of years ago I was at a popular woodworking store with my brother who was looking for an air filtration unit for his woodshop. They had one on sale for $150.00 so he bought it. We took it back to his shop and mounted it near the ceiling. It was pretty cool. We made some dust and it seemed to do a good job of filtering the air in his 16×32 building. I decided that I wanted one too, only I do things just a little bit different than my brother. On the way back to my shop, I...

Shop Air Cleaner #2: Almost Done

12-15-2013 03:39 AM by Fr. Thomas Bailey, OSB | 6 comments »

I painted the whole thing bright yellow. If I knock my head on it, its my own fault. I glued and nailed strips (1” wide) on all four-sides to create tracks for the filters. There are two sets, the first is for a cheap filter and the second is for a higher quality filter. A quick 5/8” hole in the ceiling allowed for the 12 gauge extension cord to enter the box. I spliced the cables and attached the neutral wire inside the box and put the ground and line wires through the gang...

Shop Air Cleaner #1: Start of the Build

12-12-2013 03:47 AM by Fr. Thomas Bailey, OSB | 2 comments »

Air intake for air cleaner. I used half-lap joints to build the frame (20.75”x20.75”) All the sides are cut, as well as the rabbets and dados according to the plans I drew. (Page 1, Page 2, Page 3, Page 4) The motor was put inside to take a few measurements for where to cut the air outflow. It is upside down in the picture, however. I mounted the squirrel motor to the inside wall with 1.5” wide pieces of 3/4” plywood. Some of the screws were drilled through t...
