Return A/C Vent Filter Upgrade?

[Fancy Free]

I have a 2011 34TGA with the multiple, round, A/C return vents each with its own foam "filter". While I clean the filters regularly and replace them after 2-cleanings, it seems to me there should be a better filtration material than the standard foam. Anyone have experience or ideas along these lines? Thanks!

Careful you do't restrict the air flow with "better filtration".

That's why for once in my life I'm asking first, acting later. ��

I feel you! I searched for months before I found electrostatic AC filters for mine.. I do not have the round returns, but the standard direct returns that are big and square The difference in the cleanliness of the AC coil and evaporator is significant continue the search perhaps call the manufacturer snd ask them.

Good thoughts, and yes, something like an electrostatic filter that doesn't impede the airflow is what I'm after. May I ask the brand/manufacturer of the filters you found?
