DIY SUPPER EFFECTIVE HEPA filter air scrubber
Hi, my name is Moe.
You may know me, or you may just be finding me and my pages. Im all about what works. It should look fancy but it doesn’t have to. Whatever I do has to perform at elite levels. Whether its a navy seal or an NFL player making the winning play at the super bowl, both are executed at high levels. (Not here to say that the NFL is even remotely on the same page as the marines, navy seals, etc!)
I came up with this style of filter years ago. Someone called me up to sell me a $1200 air scrubber. Perfect for construction jobs, negative pressurizing the home, etc. I almost bit the bait. He lost out by not qualifying me as a customer and following up. Im sure Mr Grant Cardone (legendary sales trainer, speaker, writer!) will scold him for being an amateur. Long story short, I decided to make my own. I ordered a round filter, came up with a big idea of using a 5 gallon bucket with removable legs made from black pipe…
Dan Holohan once said, how do you know who’s an engineer and who’s a regular individual? Ask them how the pickle got into the bottle. An engineer will say that someone created a vacuum and sucked the pickle in, or dehydrated the pickle, put it in the bottle and then rehydrated. A plain person will tell you that someone poked a baby cucumber into a bottle, let it mature, cut it off the bush, pickled the cucumber and now you have a pickle in a bottle.
Fast forward, the materials for my design are still in the shop. I came up with a simpler idea. Place a 20in x 20 inch 11 Merv or 13 Merv rated filter on the return of a basic box fan, turn it on and leave it! for high dust go into high speed. For maintenance mode, just keep it in low.
You can use this for post construction clean up, basements, shops, arts and crafts studios, working on HVAC in an attic, etc.
Please comment or email me to let me know what you think, if you had good success with this or if it was a total failure.
In the following order:
BEFORE You can see dust in the beam of the flashlight
After No dust in the flashlight beam (1.25hr of run time)
