RV Air’s all-new “cut-to-fit” filter, only available at Walmart, fits 99% of all RV AC units. The RV Air AC-300 filter contains 40 layers of anti-microbrial polyester fibers in a 16.5” x 9” air filter that helps stop the spread of harmful microbes, like bacteria, pollen and fungi.

This Walmart-exclusive oversized filter and cut-to-fit design allows it to be compatible with most RV AC units; simply lay the existing filter on top of the AC-300 universal filter and cut around the old filter for a custom fit.

• SUPERIOR PERFORMANCE: Cleans the air before it goes into your RV’s air conditioner
• MERV 6 RATING: Creates a barrier against airborne contaminants without restricting airflow that would otherwise shorten the AC unit’s lifespan
• MADE IN THE USA: And from recycled materials.
