@rmoltis can you post the link to the air filter you used.
Page 2 of bagseed hunting.
If you get this filter you will need a 6" flange to attach it to your tent port. If your port is 8" you may need an adapter of some sort.
Some farmers use pantyhose over their air intake for filtration of dust, hair etc.
@incogneato took a furnace filter taped to a box.
Then ducted that box to his intake... cheap simple and the high surface area made for low restriction.
The spectre intake
looks good and is reuseable just buy the recharge kit for cleaning. It filters amazingly well but adds restriction.
The pantyhose makes minimal airflow restriction. Good for hair and big particles, But is worst at filtering small particles.
The cardboard box furnace filter is cheap to make. Cheap to replace filter. And the large surface area makes for minimal intake restriction.
If your intake has a 8" port you could use an 8" duct and 8" flanges to the box.
You have many options which all have different efficicacy's/variables/replacement & cleaning costs.
Or you could grow with no intake filter like many people do.
If you don't mind dust, hair, and dirt on your flowers. It also prevents pests from entering a free entrance. As well as stopping potential stray outdoor male pollen.
When opting for intake filtration.
Remember that it
does add restriction to the system to add cleaning efficiency. But if your heat load isn't large (led lighting) you should be fine.
The canfan is engineered to work well under resistance/pressure :)
