Thanks. This is a very good, no nonsense, description. Most videos I've seen use 2" width filters, but I haven't been able to find them. I'm going to use your design, but use white duct tape to pretty it up😊, and keep all the pleats in a vertical orientation to prevent sagging. Thanks again.
I've watched a dozen of these videos and you're the first person to mention the air flow arrow on the filters. Thank you.
You are welcome! Glad I was able to help. Thanks a lot for the feedback!
Agreed. You’re the first one to explain which way the fan needs to be positioned for proper airflow. Thank you!
Smart man❤
Excellent video. Simple and right to the point. 👍🏼
All right i am committed now. I just bought a 20 inch box fan made in USA. I already have gorilla duct tape so all i need now is 4 20 by 20 filters and correct shape and size of cardboard !!
Awesome! The gorilla duct tape is good stuff! Going back to your earlier question, that will make it that much stronger. The filters should be pretty easy to find. Have fun with the build!
Reverse everything. The fan, the filters, all of it. It makes a better filter
Excellent video. Clean, concise, and easy to understand. Well done! Used one filter taper to that same fane and it was okay. With this clip I've seen a really clever way of clearing dust and particulates out of my shops in a very efficient way. And that tip on the HVAC is great as well. You can most definitely restrict the air flow. Thanks for making this. It should help a lot of shop owners, and also homeowners that just want cleaner air to breathe.
Your filter looks great. Nice job. Question ...would one 4 in thick filter work just as good as 4 1 in filters simplifying construction?
Four filters won't obstruct the air flow as much, because the air path has 4 times the area: 20 inches x 80 inches.
6:24, first video that made this important point clear! Very good presentation! 👍👍👍👍
I've been using a couple of the simple 20x20 taped to the box fan for several years and it works quite well as the filters are coated with fine dust after running for an hour or two. Something like this that isn't mounted to the ceiling or wall could easily be moved to another area of the house if you're working on projects outside the shop. Anyway, nice video, think I'll give it a go.
Awesome! I used to do the same. I have found this to cut down on the dust a lot faster. Thanks for the feedback Rick and good luck on the project!
How often on average did you have to replace them?
Went yesterday to buy 2” filters. Box stores apparently do not carry them. Thanks for your video demo. Best one and most helpful I have seen. Thanks!
Awesome! Glad you liked it. Thanks a lot for the feedback Lawrence!
@@HowToHomeDIY Have used my new filter for a week. I am amazed and quite pleased with it. My sneezing has decreased about 90%. Thanks again. Much appreciated!
Most interesting! I have a space this idea would work great in.
Great! Happy to hear it will help!
Thank you!!! Im so doing this! Its been very smokey here in Michigan from the fires in Canada. I saw a government prediction map showing Michigan, Maine and Minnesota are also " expected to burn" this summer.
Gonan build this! I currently have a cat and live in a one bedroom town home im getting annoyed with the oder everyoncd and while and pet hair that just seems to stay stagnant around my living room..hoping thiis helps to really suck all the hair and pet dander up
best imformative video. im going to try make one
Great job😊
Very smart !!!
Glad you liked it!
i am going to build one of those. My question is do the paper filters with the cardboard base really support your fan well enough to be stable? New sub today!!
Yeah it is actually pretty strong once it is all put together. No sagging or anything. Welcome aboard! Look forward to seeing you around 🙂
Thanks!
Have you been able to perform any real life tests to determine its efficiency?
Love ❤️ your channel 🤙🏽🙏🏽
I have not done any specific testing. Just my own anecdotal evidence that my shop air clears up a lot faster and better than other shop filters I have used. I really appreciate the feedback and look forward to seeing you around the channel!
There's a video on you tube that addresses this. "HVAC Filters VS Smoke + Pollution + Fine Dust" (The 3D Handyman)
Where in room would you set this? On floor or table?
great Video! Will this work in a paint booth?
As seen on Ask This Old House, but yours looks a lot better than theirs.
👍👍 JimE

I likes! Pretty good. Gonna try it later this spring!
It works better that all of the commercial ones I have used.
The reason for airflow direction is the physical support of the filter media - to avoid the filter media being sucked into the fan.
That may be a part of the reason but the main reason for the airflow direction on most filters is because the intake side of the filter is more porous where the side the arrow is pointing to is less porous to catch those small particles better, therefore more restrictive of air.
It’s not but we will just agree to disagree I suppose.
What is the max CFM on that fan? I have a decent 195 CFM extraction fan that I may use this for.
195 cfm won't move enough air. Lasko claims 1820 but actual is 1150 cfm. Air King is a bit better, claiming 2163, actual 1320 cfm. Credit the 3D Handyman for the research and testing of options: ua-cam.com/video/KobogQMf_Xc/v-deo.html
How long do you expect this to last before the filters become too clogged to be effective?
Hard to quantify that. Just depends how much you use it. I still am using the same one in the video but I do not do a ton of woodworking.
@@HowToHomeDIY Thank you for the quick reply. I just found your channel recently and all of your videos that I have watched so far are very informative, simple to understand, and very well made.
Our issue is more bad smells rather than dust. We don't know if its mold, sewer line leaks, or coming from the neighbors on either side. (We live in a row house.) We have had several experts come in to try to find the source of the problem (and there may be more than one) with no luck so I may try your method to help until we find the real cause of the problem.
Thanks again.
And the follow-up question: How much time does it take to replace the filters? I assume you can reuse the cardboard base, but not the duct tape.
Perhaps a more complex design that has 4 slots into which the 4 filters can be snugly inserted -- without taping the filters in place -- would be better for the long term. More labor to build but less labor to maintain.
Those filters are like $20-28 each. $20 for a box fan and $6 worth of duct tape. And then when they get dirty, you have to build the whole thing again. It's probably cheaper just to buy an air purifier.
Air purifiers are not made for a shop atmosphere with all of the large particulates like sawdust for example. They would be full in no time. Box fan wasn't that much, definitely was nowhere near $6 of duct tape, and the filters are the most expensive part but the price depends on size and MERV rating.
@HowToHomeDIY they have some cheaper filters on Amazon. Supposed to be merv 8, pack of 6 for $36. They would probably be okay for the shop. But I probably wouldn't use those more expensive filters, unless you were using it in your house or something.
Why not reverse everything and have the fan PUSHING air into the filters. A fan can push better than it can pull air. At least IF it is anything like a water pump. Water pumps can push water a lot higher than they can pull water. So it would stand to reason an air pump (AKA a fan) could move more more air if it was pushing it through the filters.
stick an airfilteer on the front of the fan too...catches one more time.
So a cube with 5 filters & cardboard base? Any problems supporting the fan?
Never use these as furnace filters, very little heat gets past them and your heating bill doubles or more.
