Has anyone built one of these things to clean up the air in their workspace a little bit? Do these actually work or is it a gimmick? I used to have one of those $100 tower air purifiers, but I opened one up after 6 months of use and saw the amount of dust that still made it through and got stuck on the inside of the unit. Some dust making it past the filters wasn't the issue, it was more so the pain in the ass it was to disassemble the entire unit to wipe off the grime with a wet towel and soap since the dust was really caked up on the housing and components. I'm pretty handy so it wasn't much of a problem, more so an annoyance, but I can imagine how many people who aren't DIY savy have been running these units for years without realizing how dirty it is on the inside.Do these DIY square fan air purifiers actually work or is there a hepa air purifier that is easy to disassemble and clean from the inside like those $350 round old school honeywell air purifiers that don't cost $350?
I built one. does a good job cleaning air but if you can't be fucked to clean out a tower filter then ripping apart all that tape and building a whole new set of filters on the fan isn't going to be any easier for you.you're going to want a more permenant frame that you can slot the filters in and out of but that will be more time and more money spent.
>>2872486Box fans like that aren't built for static pressure to push a good volume of air through those filters. They're made for low pressure air volume and silence. That said, they're better than nothing and will reduce dust by sheer volume being on at all times, but if you're using it for actual dust and smoke control you're a doofus. >$100 tower air purifierMost air cleaners for medium household rooms are like $150 now and have to go through $100 of air filters per year. If you're in a dusty shop, you're clearly trying to take the cheapest possible route and its just wasting money. If your'e serious about regular dust in a workshop area, get a legit filter system. It'll cost a couple thousand, but you'll notice a lack of dust after a month. Or you can rig up something like >>2872551 if you use a loud fan and are diligent about replacing filters. Something to note; HVAC filters like that should be replaced (depending on total run time) every 2 months or so, even if you have 3 of them running a high flow fan (as you should be) in a dusty workshop you'll be replacing them once a month. Each filter is at a minimum $20.
>>2872569> guys, c’mon buy shit, spend thousands; nothing else works unless you spend a couple thousand, even if you don’t need one c’mon and buy buy buy stuff. go into debt, as long as you buy. buy a subscription too, and services… better yet hire someone to buy them.Yeah, no.
>>2872597Ah, I see you're not yet familiar with employee safety liability in the workplace. It may not be for 30 years, but it'll wreck if you DIY in a shop with employees.
>>2872551I already have one of those square fans and it's way easier to disassemble and wash than one of these annoying ass towers that gets dusty inside all of the crevices and electronic components. Good to know it works. Going to pick up some air filters tomorrow and make myself a box.
>>2872569They're more powerful than those $300 tower ones that are a pain to disassemble. If anything, I wish there was an easier way to lower the fan speed since mine only has one mode. These old school honeywell donut air filters are probably the best ones I've seen and are so easy to get into and clean. Too bad they've gone up in price since COVID and are mostly discontinued and you can only find those shitty tower ones with forever dust inside of them. I can't imagine the amount of people who have been running them for years not realizing how much dust has accumulated in them.
>>2872604>>2872597Replied to the wrong guy, meant to reply to >>2872569.Did you build that donut one yourself? What guide did you follow. Yt vid or blog post? What blower motor are you using?
>>2872486the ironic thing about them is that they kick up more dust off the ground than they'll ever pick up
>>2872606>>2872597Residential. Also thanks for reminding me to force my employees to sign waivers in exchange for me not firing them.>>2872606https://www.youtube.com/watch?v=L0SrX6O3Y-A
>>2872486I built one when we had a lot of smoke a few years ago in WA state. It did a great job and you could see how filthy the filter was with brown residue after a week of smoke. Is it a perfect solution? Nah, but it's cheap and effective.
>>2872658What if you add a cardboard tunnel at the other end to disperse and diffuse the air output?
Easy work
>>2872486Of course it's legit. Hell, this middle school kid just got granted 11 million dollars to make these things for every school in her state. The government wouldn't throw 11 million dollars at a gimmick, would they?>>>/pol/489233369

>>2874143We wuz inveters 'n shiet.
>>2872486They work incredibly well but you have to use a centrifugal blower that's matched to the filter specs
>>2874427Oh, yeah, baby... suck all the dust for me...That is awesome.>>2873964This setup is quite effective.I even saw one with 5 filters instead of 4.
