Corsair Air 740 case - bottom intakes/ filters?

[Perfidia]

I want to mount some fans on the bottom, however, there is no dust filter. Would any 140mm fan filter work or would I still be getting a lot of dust from the bottom intakes? Or Would I need to have a dust filter tray thing to stop dust?

Please give me filter recommendations if you have any.

Thanks!

You can use Demciflex magnetic filters for your Air 740 bottom intake,

My Skylake build (full specs in my sig) sits in 760T v2 case and i have full Demciflex filter kit for it to keep the dust out. I like the Demciflex filters for several reasons:
1. High grade mesh that catches even the smallest bits of dust.
2. Easy to mount due to the flexible magnetic strip each filter has on the outer edge.
3. Easy to clean. Just rinse under water and tap filter dry with towel.
4. Good looking. My filter kit fits perfectly for my 760T v2 case and it also has matching color theme.

I need to clean my intake filters weekly while the fan behind filters is spinning only about 1100 RPM. Either i live in a very dusty place or the Demciflex filters are that good. 😀 Under the spoiler is a combined image of Demciflex filter kit on my 760T v2 case.

Since there's no full filter kit for Air 740, measure the bottom intake area and buy square or round filter for your case. Don't forget to pick your preferred color too.
