>The 20" box fan + MERV furnace filter hack
Living here in the west with hyper toxic AQI for the better part of two months now, I decided that the low CFM and leakage of a DIY box fan are not adequate to keep up. I went with a far more industrial solution: I went to an indoor grow shop and bought an activated carbon filter and high CFM inline fan. Cost $150 and is a bit noisy, but has been well worth it.

- wintermutestwin 5y agoI wouldn't recommend this specific setup, but these are the type of filters/fans I am talking about: https://www.amazon.com/VIVOSUN-Inline-Controller-Ducting-Ventilation/dp/B07YZKWNG5/ref=sr_1_7?crid=I4OFRYHOPKQC&dchild=1&keywords=carbon+filter+for+grow+tent&qid=1631143912&sprefix=carbon+filter%2Caps%2C298&sr=8-7 https://www.amazon.com/VIVOSUN-Inline-Controller-Ducting-Ven...
- jonahhorowitz 5y agoYou can buy carbon activated MERV filters. I got some from Nordic Pure.
- Exuma 5y agowhat MERV rating is that. I do that now but I thought it's MERV 8 which really won't remove much at all
- rsync 5y agoI’m surprised to hear this - a standard box fan from ace has something like ~600 cfm, right ? That’s fairly high - what is the size and cfm of the fan you bought?
- wintermutestwin 5y agoNot when you strap an HVAC filter on it. My setup is ~600cfm with much more filtering. Not sure what the MERV is but the cylindrical layer is much thicker and heavy duty than an HVAC filter.
