How to Clean Your RV Air Conditioner Filter

Summertime means it’s time to hit the open road and explore the great outdoors. But before you take off in your RV, it’s important to ensure that you’re traveling in comfort, which means making sure that your air conditioning system is working at its best. A clean air conditioner filter can help improve your RV’s air flow and keep your air conditioning system running smoothly.

In this post, we’ll share some tips on how to clean your RV air conditioner filter so you can enjoy a comfortable and refreshing trip.

1. Locate the Filter

The first step to cleaning your RV air conditioner filter is to locate it. The filter will be in your air conditioning system and can usually be accessed by lifting a cover on your RV’s ceiling. Once you’ve located the filter, remove it from the system. Most filters are disposable, and you can buy replacement filters of the same size from your local RV or home supply store.

2. Clean It If Reusable

If your RV air conditioner filter is reusable, follow the manufacturer’s instructions for cleaning it. Usually, you can clean a reusable filter by vacuuming or washing it in a sink or bathtub. Be sure to let the filter dry completely before reinstalling it.

3. Buy New One If Disposable

If your filter is disposable, it’s time to get a new one. However, if you are on the road and don’t have access to a new filter, you could prolong the life of your current filter by cleaning it. To clean your disposable filter, gently vacuum the filter to remove any debris or dust. If you don’t have a vacuum, you could also use a soft brush to remove the dust. Be careful not to damage the filter as it is delicate.

4. Install the Filter

Once you’ve cleaned or replaced the filter, it’s time to put it back in your RV’s air conditioning system. Make sure the filter is securely placed in the unit before reattaching the cover.

5. Enjoy

When your filter is clean, not only will you experience better air flow and cooling, but you’ll also eliminate the buildup of dirt and mold. Keeping your RV air conditioner filter clean is important to prevent the spread of mold and bacteria, which can cause respiratory problems and other health concerns.


Traveling in an RV can be a fun and relaxing experience, but it can be a lot less enjoyable if your air conditioning system isn’t working properly. Cleaning or replacing your RV air conditioner filter is an easy and straightforward task that can help ensure that your air conditioning system is working at its best.

Follow these tips, and you’ll enjoy a comfortable and refreshing trip.
