You just need to increase the total area of the filter material that the fan is pushing air through. I've seen people shape them into a triangle or box with plastic/tape over seams or openings.
- fighterpilot 5y agoDo we know how the air flow improves in proportion to surface area? I assume it's not quite linear. It would be good to know whether it's worth the effort to do what you're describing.
- akozak 5y agoI'm sure there is an answer to that but this is DIY, so maybe just touch the fan while its been operating for a while, say "damn that sucker's getting hot!" and add more surface area until satisfied you won't burn your house down.
