In this free video lesson, RV Repair Club contributor Joshua Sherer walks you through the A/C filter cleaning process so you can get your RV vents running more efficiently. On typical rigs used for standard travel, vents don’t need to be cleaned more than once per month. However, if you’re frequently traveling in regions where the air might not be so pure, you should consider taking care of your vents more often.

To begin the A/C filter cleaning, Joshua recommends first shutting down the unit. With the unit off, remove the filter and clean it thoroughly with dish soap and plenty of water. You’ll repeat this process with the grate. While you clean the grate, hang the filter outside to air dry. When the filter is dry, put it back into the grate, and screw or clip both back into the vent opening. As mentioned before, you should complete this process at least once per month and more often if necessary. Keep your filters clean, and you might see a big difference in the efficiency of your A/C unit!

    Hi I have always been told NOT to dump water containing dirt from cleaning into my grey water tanks. Please list the PROs and CONs of doing or not doing so.

      You don’t want to put a lot of dirt down the drains but using sinks and showers regularly is doing to be putting dirt down them anyways. When you wash dirty hands or take a shower there will be dirt going into the drain. You shouldn’t deliberately poor a bunch of dirt down the drain but cleaning off these filters, dish water and little amounts of dirt are going to be fine. Too much can be hard to flush out but if you use a lot of water while there are contents inside it helps push it all out of the drain.
