I run with the "air cleaner element" in the On position 100% of the time due to living in and around a large Industrial Area, not to mention that it is just nice to breath cleaner air all the time!, and am wondering the procedure for cleaning this element, and or replacing it.
At what time does it need replacing?
At 67,000K, I can now smell certain things outside, when before it filtered out everything.
Could you let me know what you know about this?
