Does a wet towel draped over a box fan make for a decent air filter? It's really dry and dusty out here.

[Anonymous No.974834]

I would go for something thinner like that crap on the bottom of your couch or hey lightbulb dryer sheets

Won't get much airflow through it, plus it will dry in like 5 minutes.
What's with the recent air filter on a fan fad?

>wet towel draped over a box fan make for a decent air filter

If it is constantly changed (kept wet) then yeah, wet towel will attract and trap dirt because of the wetness, but it will be dry very quickly.

Be careful not to burn out the motor.

shitty fans like this or "box fans" are not designed to have the aireflow obstructed by filters or towels. they will not pull enough air thru them to be effective. they are simply not powerful enough and are not designed for such.you would need a blower thats designed to pull air at high rates to be able to effectively pass air thru a filter medium. standard fan blades just dont have the ability to increase pressure for this.

Just buy a cheap filter from a home improvement store and tape it to the front or back. Worked great for my cheap throwaway box fans from Big Lots. The fan motors still work fine after years dispute this

With spring comes allergens, and suddenly everyone is constantly reminded of it.

[Anonymous No.974854]

Northern hemisphere is heading into springtime so allergies. Don't worry, in another month and a half filter fans will go away in favor of ice water powered radiator fans.

A few months after that cheap diy heating threads. Then the cycle is complete. You could almost set your calendar to these threads.

I'm going to do this for my room. Wife bought a fancy allergen fan thingy for almost $200. I'll put the shitty cardboard box fan in my room and save.

Just cause the fan doesn't break doesn't mean it's being useful. Box fans simply do not do useful work if you obstruct their airflow with a filter.

You'll get 20-40 times the airflow using an inline fan for growing "houseplants". Not because it's capable of 20-40 times the airflow, but because the filter won't buttfuck it.

Plan for actually good air filter:

Parts:
- Hydroponic fan for ventilating your inexplicably house-bound lettuces
- IKEA Samla storage box, plus lid, plus clips
- car pollen filter, any size you like
- optional: some flexible ducting and a ducting flange plate

Method:
- put fan inside box
- cut hole for air to exit
- if you're using ducting, seal the flange plate to the hole you cut, then zip-tie the duct to the fan and flange; if you're not, poke the fan through the hole and gaff it
- drill a hole for the power lead, remove the mains plug, poke through and reassemble
- mark up the filter on the lid, build some kind of holder from scrap plastic and hot glue
- drill a bunch of big-ass holes so the air can get through the lid, but the filter can't
- seal the filter to the lid with gaff
- clip the lid on so it's airtight

Done. A diy air filter with at least an order of magnitude better flow than anything you'll buy retail.

Truth. Also squirrel cage fans. They are made to deal with sort of stuff.

>or hey lightbulb dryer sheets
Dryer sheets have chemicals that need to be vented out in the dryer. Putting them in the air is toxic and causes cancer.

[Anonymous No.975175]

>>975166
no they don't. they're safe to use in electric dryers vented into the space the dryers in...

they work by adding a small bit of wax over the clothes... it knocks down the static... if you don't believe me go look at the lint screen of someone who uses a fuckton of them.. it'll usually have a waxy coating clogging half of it unless they clean it regularly

That's actually supposed to be vented outside the building entirely.

[Anonymous No.975199]

>>975187
for gas dryers yes, however you can vent an electric dryer into the same space... not saying it's perfect.. if you do it in a small closet you'll end up recirculating damp air through the dryer and it'll take forever to dry your laundry... but if you've got an unfinished basement then your perfectly fine to vent it into the basement.. hell if your in a colder climate you already paid to heat that air.... they even make lint traps specifically designed to let you do this (air blows down onto water to trap lint then rebounds into room)

[Anonymous No.975225]

remove the source of the dust? isnt that an option?

could always get a hepa filter unit. line your place with 6 mil plastic, set up negative pressure units, maintain a -2% air pressure (compared toutside pressure), and run the fan 24/7. voila, no more dust

Hay guise, what if... no no, listen! Guys! Listen... What if you use a corner of the filter cloth as a wick to draw water from a vessel that you place on top of it?

Enjoy your water moisture problems. I bet your the type that makes a bathroom with a shower/bath that doesn't' have an external vent fan.

Your wet clothes contains the chemical dihydrogen-monoxide. That shit kills thousands of people every year.

It's ok though. The toxic chemicals in the dryer sheets cancel out the toxic chemicals in the clothes.

Theyre good for developing air pressure. Filters need a preset level of air pressure to function otherwise they become 100% efficient.
