Should You DIY a Box Fan Air Filter or Buy This Instead?

[@tic857]

I just wanna appreciate Lasko being like, oh...people are doing this lets make it easy for folks so they can just pop one in. Unlike other air purifier companies who go out of their way to make sure you have to find an obscure shape,size, thickness and make it obsolete in 3 years.

I'd imagine why the Lasco Airflex is out of stock would be that everybody knows that box fans are the greatest.

[@GanderFlight]

I've been happy with the purchase - so maybe!

[@nich586]

I did this DIY and I'm happy with the result. It should be noticed that the box fan sucks air in through the perimeter (corners especially) of the front grill. To achieve optimal filtering one has to tape or somehow cover that perimeter area. The Air Flex front grill does not take this into account.

[@GanderFlight]

[@dakotaneighbors7133]

Front side? So the side it’s blowing air? It sucks in air through the front? Doing this soon so curious

[@nich586]

@@dakotaneighbors7133 Yes. Run the fan and move a piece of tissue paper near the corners of the grill. You'll see how the fan sucks in air through the front.

[@rvgearandfar]

@@dakotaneighbors7133 put the filter on the back. Because there isn't a shroud on the front of the fan, or because the fan box isn't circular there is space in the corners - between the square corner and the fan blade, that some air is sucked in from the front grill - its negligible and not worth paying attention to unless you really want to geek out about it - put the filter on the back of the fan.

[@lylawaters6345]

I have been using bungee chords to hold furnace filters onto my box fans for several years. Our box fans run 24/7/365 for not only air circulation but "white noise" to sleep as well. A standard box fan WITHOUT a furnace lasts for about 2 years before it dies. WITH the furnace filter a standard box fan lasts 3-4 years. (Our furnace is from 1986 with the very thin filter that comes in a roll that really doesn't do much other than catch dust bunnies and it really doesn't do anything for the fact that we have long hair cats). Adding the furnace filters to our box fans has made our indoor air much cleaner and in my experience the traditional air filters circulate as much air on high as a box fan does on low. Not to mention, a box fan is MUCH CHEAPER to replace when it dies and it is all standard sizing. We also decide what level of filtration we want in our home at any given time of year.

[@lylawaters6345]

I didn't mention, I use the filtrete elite filters. They are either a 13 or a 15. When researching furnace filters for my Mom I discovered that more pleates=more surface area=better air cleaning.

[@GanderFlight]

Sounds like you've got it figured out for your space!

[@johnparis6233]

Did you set it up where the fan was blowing dusty air OUT of the room through the window? Or blowing fresh air (with the filter) into the room?

[@furny0101]

I'm glad I found this video, thank you for producing it. I bought one of these about 10 years ago at a Rite Aid and it is still running. I have broken the feet and was wanting to get another one. Thought they were discontinued. Bummer is that i remember this costing $19.99 at the time.

[@GanderFlight]

Prices have certainly gone up huh?

[@Jackstraw911]

I made my own with a $12 fan I got from Walmart and I vacuum the filter with my shop vac. 😊

[@GanderFlight]

I went that route to begin with: kzbin.info/www/bejne/b6etnGh4gp2ri9E

[@robingulde2706]

Three questions: 1) The fan comes with a Merv 10 filter; will the fan handle a Merv 13 or 14 filter? 2) In a double garage woodworking setup, would it be beneficial to have 2 or 3 if these units spread around the shop? 3) I'm guessing the fan draws the dust into the fan and onto the filter. Is the motor sealed so the dust doesn't choke it? and, can a thin filter material be placed over the filter cartridge so it can be vacuumed from time to time?

[@kristinect]

I just finished putting air filter pads on the back of all my regular fans (not even box fans). This came at a great time. Need a box fan now for our incredibly dusty apartment. Thanks.

[@GanderFlight]

Glad it helped

[@3DRundown]

That's awesome. I make them, to filter when I paint. Garage Sales and Garbage days, and they usually cost me like $5 each, but, this is super cool

[@robertgaines-tulsa]

The first time I made a box fan air filter, the box fan burned after after a month. I wasn't impressed. What I ended up doing was using the old box fan case as a filter holder. The filter is pressed against weather stripping and held in place by bungee straps. The back was enclosed with cardboard except for a hole for a dryer vent connector. A dryer hose connector was glued over the inlet of a floor blower, and the filter holder and floor blower are connected with a dryer hose. It's worked for a number of years with constant use. To be honest, it's probably quieter than a box fan even though it produces a lot of white noise. It covers up my tinnitus and helps me sleep.

[@GanderFlight]

Sounds like a cool setup

👍 Nice

[@RideByNight]

This is a really neat idea. If they came out with a version that could hold a 2, 3, or ideally 4" filter, I would buy one for sure. The 1" thick filters don't work out so well in the workshop but they might do better inside a home.

[@missjuhee]

Thank you for sharing this other option. Do you know how much more/less effective the single filter vs. the 3 filter (Rosy something??) way is? Is it just a matter of less sq ft of filter resulting in less air filtered which I am fine with or is is matter or some mechanical or other reason? Thank you again. I really like that you decided to provide this info.

[@GanderFlight]

Yeah the Corsi Rosenthal boxes are more filters and therefore can filter more air faster and don’t have to be changed as often because there are more of them- also takes up much more room

Not sure why I'd bother with either. Hold an air filter against the back of the fan while you turn it on. The vacuum of the fan will hold the filter in place as long as it's running. No need to use J-channel, zip ties, or tape. No need for a $60 version of a $20 Walmart fan. Physics has this one handled.

[@INoIFearIGaming]

I personally used tape to seal the filter to the fan to minimize air gaps. It's not 100% air tight, but definitely better than the filter just being held in place by suction

[@Ice_Solid]

I saw the price and I just started laughing

[@delwoodkelp8590]

@@INoIFearIGaming No need to use tape to minimize the air gaps. The fan with filter (even leaking) will in short order replace all the unfiltered air as it runs several times through the filter. ALL the air will have been filtered in short order. See room size.... do the math. Cubic feet per minute of cheap Lasko fan is 1,710 cfm. Room 18 x 12 x 8 is 1,728 cu ft. So in one minute the entire amount of air is run through the filter.... by 10 minutes... probably 98% of the air has been filtered at least once. Sealing the leaks is a waste of time.

[@AgentSmith-x9p]

​@INoIFearIGaming Yes and not only that, the diameter of the fan blade does not even reach the edges of the box because obviously it can because its a circle in a square, but i have watched smoke airflow expermients with these that show as you increase the resistance to the back with filter media the fan will actually start sucking in air from the 4 corners on the front and bypass the filter entirely. To minimize this i cut out a cardboard square with a circular cutout the same diamater of the fan and tape that to the output. These fans are great but they will try to suck in air from every crack of unrestricted airflow.

[@AgentSmith-x9p]

​@@delwoodkelp8590Sealing leaks is not a waste of time, the design of a box fan is very inefficient, the more you restrict the air flow at the back, the more you inrease the vortexes that occur in all 4 corners of the box fan due to fan blades not reaching the outer perimeter of the housing (Thats why a circular duct or housing would be more efficient) As soon as these vortexes increase the fan will just start sucking air in from the front 4 corners and pushing it out bypassing the filter because the air i gonna take the path of least resistance. You can see this effect fully with a smoke machine. You are right though, run the fan long enough and eventually a lot of the crud will end up in the filter, but this design definitely has room for improvement and painters masking tape is super cheap an easy to fix a bunch of the inefficiency.

[@anneann9127]

The problem with the Lasko Airflex for me is, it's only using a Merv 8, where as if I did a DIY I would opt for the Merv 13.

Ineffective design. Air circulates around the corners of the box fan and creates a vortex that significantly impacts airflow due to turbulence. I tried this design first and observed that the filter was collecting impurities on the side facing the fan around the corners.

I think the filters with the aluminum 'fencing' on one side some filters may add an added layer of cleaning power to the air by grabbing larger particulate before it is embedded into the deep creases of the pleated fibre mesh, extending it's life under 'normal' conditions. But, living steps away from a construction site, or if u live on a dirt road, and your front lawn is not far from that road, and there are no tall shrubs that span the width of your home, to help catch high dust levels, your filter will not do much. imho. If you can't see a difference btn the front and back of the furnace filter, I bet it was cheap. I want a fully washable/reusable, filter with the charcoal, that has a metal frame, and a fiber mesh that can be washed and reused, and replaced as required. Has anyone got experience making an air filter system using 4 filters taped together , making a square, then laying the box fan on top, facing up, to create one large purifier? 20x20 lasko fan =$40×13% = 45.20 CAD, 4 Filtrete 1500mpr (approx merv 12) 20x20x1 filters @23.97 13%=108.50.

[@GanderFlight]

The 4 sided box will last longer and allow for more airflow - but you'll have to buy 4 filters upfront and it takes up a significant amount of footprint space. As far as is it big enough for your living room and kitchen area - it depends - how large are your living room and kitchen areas? It also depends on how often you want the air in the room pulled through the filter - this will filter your living room/kitchen area eventually but it'll all depend on how much volume of air is in that space as to how often it will filter the whole room. As far as volume -sorry I don't have any measurements on that to share with you - but it is a fan and therefore not silent, even on low you'll hear it running. If you're looking for something silent you'll want to check out air filters purpose made to be quiet.

[@carlthetruthwilliams9447]

Your original design is still the best, IMHO...because the commercial version has slats which lower air speed before passing through the filter...

[@GanderFlight]

I've used both now - and if I have to buy one from scratch, not repurposing an old box fan, I like the lasko better - the bigger feet give it a more sturdy base and the filter holder is so easy to use.

[@jim3922]

Cool! I didn’t know this existed

[@jeboccuzzi10]

Just ordered from Amazon. No brainer

[@stans5270]

At 3X the price and having the DIY already, I'll stick with el-cheapo.

[@GanderFlight]

If you already have the parts - absolutely, but I'm not sure where you're getting 3x the price...

[@hairpunut]

I'd only see it being 3x the price if you already had a box fan and just bought a cheapo filter. Or maybe just a roll of tape lol. I just use tape, filter and box fan probably 50 bucks. This fan is 60 bucks includes the filter lol

[@ProfessorDIY]

Price too hight fior what it is

[@Wickedjc2119]

Only reason for the air flow is one side of the filter is reinforced so it don't collapse inside the furnace

[@GanderFlight]

👍

[@valbrideau311]

$60 try $120 here in Canada

[@JorgeGonzalez-yt8sy]

I thought these would be $30 but they're $60. how is that competitive to a $20 lasko, a $5 filter and some tape ?

[@GanderFlight]

Because you're not getting a merv 10 or 13 filter for $5....

[@themodfather9382]

I used a spacer to prevent air deadzones. My entire filter turns gray, there is no gray circle in the middle.

[@GanderFlight]

Spacer between the filter and the back of the fan grate?

[@themodfather9382]

That's right. I just built a frame out of cardboard. 4 pieces. @@GanderFlight

[@bm90025]

California won't allow it on Amazon

[@B.A.Bassangler]

Thanks so much! I'm glad I revisited this project since my last research. Are there any worries to use MERV 13/14 with the 2 in 1 fan?

[@GanderFlight]

I personally wouldn’t have any concerns with it- but you’ll have to make your own decision.

[@Muffinman2nd]

ordered one before the video was over

[@DanStiel]

Unavailable in California :( "This product does not meet California air cleaner regulation requirements, and cannot be shipped to California"

[@warjak1]

lasko box fan at walmart $20 20 x 20 furnace filter 98 cents fleet farm lasko with pretty filter holder $60 yeah lol I'll stay with my duct tape an bungie cords cause I can buy 3 fans for the same cost

[@அசுரன்]

Iam waiting this video from tamil nadu. Hai brother i wanna buy this type of air purifier this model link share please 🙏

[@GanderFlight]

The most updated link is in the video description - thanks for watching!

[@அசுரன்]

@@GanderFlight thank you brother 🙏

[@jamestesch2118]

We had one it burned up in 24 hours maybe it was defective but I still won’t buy another one for a fear of a fire

[@GanderFlight]

Interesting - we've been running them for years

[@ryancovington5636]

The control unit fell off the first time I used this box fan

[@GanderFlight]

Did you return it?

[@llaflotte]

Welp, the main downside of the Lasko Air Flex for me is that it "does not meet California air cleaner regulation requirements, and cannot be shipped to California" :/

[@GanderFlight]

That's pretty ironic...

[@brodude3709]

Does it use too much power or something?

[@Michael-hb4wc]

We did this with 1 20x20, 3 10x20s and a s'load of tape 😅

[@GanderFlight]

That'll do!

[@johnr5545]

Thanks god bless

[@GanderFlight]

Enjoy!

[@cherokeesfinestindian]

I have youtube premium and still get ads. DAMN!!

[@GanderFlight]

No one paid me - not an ad, but rather the information I wanted to know and SEE before I purchased.

[@JO3BID3N-is-a-P3D0]

this is exactly what i need to take my poor mans rattle can spray painting to the next level! thx to bidenomics i cant afford a paint booth, but this fan will definitely help reduce floaties in my garage space.

[@GanderFlight]

Most definitely would help - make sure to keep that door open too!

[@LygerTheCLaw]

$75 versus a $16 box fan and $4 filter is hardly "nearly the same price". it does look much tidier though.

[@GanderFlight]

you haven't been comparing apples to apples then - box fans are near $26 near me and MERV11 Filters are $40 for 4pack - so conservatively $36 plus whatever you use to attach the filter to the box fan - but yes, you're paying for the larger feet and the filter housing to be integrated.

[@andrewsides1215]

I loved you in Superbad.

[@GanderFlight]

???

[@kingbradarmy]

😂😂😂😂😂

[@tonyh.9957]

Buahaha that's funny he does look like him

[@bryonparffrey5680]

Great concept but Lasko hurries to market and didn’t quality assure the sides don’t seal or overlap lap and seal therefore sucks is air all around fan and air all around sucked in bypasses filter. Plus they don’t make it for a 2 inch filter. one still needs tape to seal around filter holder so why buy just add a filter any dive and tape it or like is a better seal that Lasko overlooked to get to market BA

[@GanderFlight]

Thanks for the perspective

[@calmjones6399]

I cut a circle in the filter where the motor is so the motor doesn't get hot and burn out or burn down your house 🐾💗

[@GanderFlight]

Thanks for sharing that variation

[@myuselessMind-g8m]

Well your video convinced me 100% to get one... No one will ship to California 😒

[@GanderFlight]

Oye

[@TexasBulldog74]

Both Amazon and Walmart say they can't ship to California because it doesn't meet standards in air quality... WTF

[@GanderFlight]

Hahaha - ya gotta admit thats kinda funny

[@drphibesrises]

I found the fan on Amazon but due to "California air cleaner requirements" they can't ship to CA, but they can ship a plain one with zero filtration, no problem. CA thinks people are too stupid to make decisions on air quality they breathe.

[@MarcusRefusius]

Why MRV 10? That doesn’t do ya much good. MRV 13 should be the minimum.

[@GanderFlight]

Its what comes with it - easily swap it out.

[@colonelradec5956]

You can literally just tape it on... Or even not that. Sucktion it to the back of the fan..

[@GanderFlight]

You could and it would mostly stay in place as long as the fan is running

[@76_SPZL]

This is a company paying attention. So glad this exists.

[@GanderFlight]

👍

[@donnaparks1919]

I lost count how many expensive purifier i went through

[@GanderFlight]

Yikes!
