I found the only vendor of AC filters that are washable but they're located in the Philippines. They're called Torque Filteration.

Anyway, they quoted me $34 for a filter, however 3-5 day shipping costs around $38. But they did say that they can fit around 6-8 filters in one package while keeping the price the same. So if anyone wants to jump in on this let me know, I would be dividing the shipping by however many people we get. Hopefully we can get atleast 3, so shipping would only be ~$13 per person.

They already created my filter. But shipping will double the value. I know we can create our own, but we give up the grooves that trap and still allow air to go through. I will post pictures of what they sent to me. So lemme know if you're interested.

I can get them shipped to my house, then ship them out to you guys myself.

Price of shipping per person
2 people ~ $19 shipping
3 people ~ $13 shipping
4 people ~ $9.50 shipping
5 people ~ $7.60 shipping
6 people ~ $6.33 shipping

 

I'd be weary of washable in-cabin filters because you would have to be very careful/cautious how its washed and if they don't dry properly, you'll run the risk of introducing or creating mold and bacteria that can definitely affect the air you breathe in your car...

 

Just changed mine, for the first time after 70k miles and it wasnt as dirty as i expected it to be. The filter cost me 12 dollars from kragen.
The washable ones are a good idea, but I'm lazy and would rather just rip out the old one and toss in a new one.
