Your RV AC filter serves the important purpose of protecting the inner workings of your rooftop air-conditioner. That’s why an AC filter upgrade is one of the most important RV improvements you can make. It’ll lead to a longer life for that particular appliance, healthier air, and greater peace of mind. Let’s dig in to see more about these filters and which ones are best as upgrades.

Do RV Air Conditioners Have Filters?

Yes! RV air conditioners have come with filters since the dawn of ACs in RVs. The RVing lifestyle often involves exploring the outdoors where dust, pollen, and more are prevalent in the air. Your filters prevent this stuff from getting into your cooled air. 

Where Is My RV Air Filter?

Your RV air filter generally sits under the AC vent cover on the inside of your RV. To access the filter(s), simply unscrew your entire AC vent cover and drop it down. The filter(s) should be visible right away.

Many RV air conditioners feature two filters, one on either side of the vent cover. You can also consult your RV owner’s manual for the exact location and specs for your model of AC. 

How Often Should You Change Your RV AC Filter? 

You should change your AC filter after 150-400 hours of use. That’s a wide time range, however. Where you fall will depend on the areas you camp in. For example, if you tend to camp in areas with wetter climates and less dust, you can push more toward 400 hours of use before replacing your AC filter. If you love desert camping, you should cheat toward replacing your filter(s) after just 150 hours of use because of the dust floating around those parts. You should also clean your air filter every 30 days to maximize its lifespan. 

Benefits of Upgrading Your RV AC Filter

Factory filters keep debris out of your AC but not necessarily out of your RV’s interior. Upgrading to a more advanced filter will offer you several benefits. 

First, you can buy filters that will last longer than your stock variety. Second, you can upgrade to a filter that will remove odors, allergens, and more from your air. And finally, you can upgrade to filters that lengthen the life of your AC.

What to Look for When Upgrading Your RV AC Filter

Upgrading your filter is an affordable choice that offers a number of benefits. There are many varieties of filters out there, so it’s important to know what you should look for when shopping for upgraded filtration. 

Size

AC filters usually aren’t one-size-fits-all. While you can cut some to size, others are specifically shaped for certain brands. Ideally, you’ll want to look for a pre-cut filter for your specific air conditioner. 

Length of Use 

One of the best reasons for upgrading your RV AC filter is to increase its lifespan. Upgraded filters will usually offer more longevity than the factory variety, but it’s important to confirm this for any upgraded filter you’re looking at. 

Keep in Mind: This summer stay cool with the right air conditioner. These camping air conditioners will do the job!

Filtering Capabilities 

Will your new filter remove allergens? Odors? Pollutants? Many upgraded filters do just that. This RV modification is an opportunity to create better air quality for you and your family. 

Filters are rated based on Minimum Efficiency Reporting Values (MERVs) that report a filter’s ability to capture particles. MERV ratings range from 1 to 16. The higher the MERV rating, the better the filter will be at capturing particles in the air.
