Would not even think about going a year without changing the AC filter with the dirt here...but then electricity and blower motors may be a lot cheaper here..

Check out www.discountfilters.com

I bought a case of filters for my HVAC system and delivery was included. They seem to be quality made.

I took a look at mine a few weeks ago and after 9 months it was still pretty clean. I am not very concerned.
