What about the bottom? Why not use another of the cardboard boxes and block the bottom off properly so that you don't get air sucking underneath the bottom edge of the filters? I'd also make your shroud hole smaller and reverse the cardboard so that you have the plain side showing.

@@wheepingwillow24u17 You just sit it in whatever space you want to filter the air in. It's not for a grid down situation, it's for the current bushfires etc. We've had several years where the smoke has been horrific from bushfires, and an air filtration system was desperately needed for anyone that had breathing/lung problems. We still had power the whole time. The filters that he used ARE HEPA filters. You can't use those filters without a fan though, they don't do anything without airflow.

Your box will work well for filtering inside air. Also living in a dry wildfire area I've taken a slightly different approach. I've added a second layer of filters to my roof mounted swamp cooler. Like with your box, sealed so all air passes through the filters. The wet filters aid in catching the particulates from the air being drawn into my home. The fan adding positive pressure to the air inside my home helping prevent smoke from entering around doors, windows, etc. Plus it's efficiently cooling my home in the process. Most wildfires here being in the heat of summer I've found this method works best for me.

The merv13 filter rating is the right rating for floating viral removal. Don't be tempted to reduce the filtration rating if this is your goal. This rating can be hard to get in pandemic situations so if you plan ahead stock some of these filters in your preps!

Built one of these at the start of the pandemic when masks ran out and not as much was known about Covid. Got filters that I believe would have been good enough for viruses and I think this would still have been good if someone in our house got sick and we could purify the air a bit. Maybe excessive for Covid, but works great as a DIY air purifier for allergies, smoke, a dusty shop, etc.

You don't even have to have 4 air filters, just one taped directly into the fan with the air flow directions aligned will also work. I'm sure you'd need to replace the filter more often. Just tape works, no wire, screws, whatever else you listed.

I built a simplified version of this last year using 20x16x2 filters and even though it is not as efficient as your design it does a fantastic job of eliminating wildfire odor in the house! This is sooo much cheaper than replacing the expensive filters in my fancy air purifier. Your shroud has given me an idea of how I might frame it so it doesn’t have to be taped enabling more compact storage and the ability to use the fan for other stuff. (Not as efficient as your design but still effective for the amount of smoke that I usually deal with.) I hope everyone understands that this really works!! Thanks for sharing!

This build is super practical because it can be stored in a much smaller package.👍 In an instant of genius, I slept 2 nights with the window open while we were getting most of the smoke in Quebec. Took me almost 2 weeks to stop coughing and I live pretty far from those fires. I did buy a small air purifier for the bedroom afterwards and been running the AC continuously since. If you snore or barely breathe through the nose at night, you should try a HEPA filter in your bedroom.

These cubes fans are excellent on so many levels. The fact that the fan creates low pressure increases its structural integrity It is a low energy, low resistances, means to steadily purify air. You can vacuum that outside carefully and reinvigorate the filters. These have so many applications. They are great for general air-quality They are a superb measure for wildfire smoke or other particulate contamination during industrial accidents or fires. If there was a radiological incident, these would at least filter out particulate based contaminants. Just be wary that the outside of the device is going to be steadily coated with whatever it is you are trying to filter. Great job

Hi, I don't understand why the air flow is this way instead of reversed where all the "dirt" would be kept inside the box. I like the project, I just wonder why not build it the other way so when it's well used all the dust/dirt is on the inside for easier disposal. Also if the box is bumped or moved there isn't all that filter dust on the outside of it. The draw back I guess is the fan get's dirty too since it's the dirty air coming through.

Drop in/ changeable filters? Next project! 😁

Slight alternate idea... Same materials, just more of them. It will be more expensive, but you will NOT have to tape up the filters every time you buy/find new ones. Buy *4* 20' box fans, and use all 4 boxes (not the fans) to make a housing to hold the filters. So whenever your current filters run their full lifespan and they cannot be cleaned safely, you can remove them and insert new ones to continue filtering the air you breath. (Might need 5 boxes...)

How would that work? The boxes are solid. Wouldn't it block the filters. If it works then purchasing 20 by 20 card board boxes would be less expensive and just purchase one fan.

Thanks! Where do you place it in the room? Is the idea that all windows are closed and it’s recirculating air in the room and filtering it out?

Instead of cardboard on the bottom how about a sheet of say 3/8" plywood with a couple of handles so ti can be easily moved around?

Good video! You can also use it if you live in a dusty area to try to get as much dust and stuff flying around!!!!
