What to look for when upgrading your RV AC filter?

Adding filters can be a good option with several advantages. Filters vary and so a good understanding of how to buy a new filter is essential.

Filtering capabilities

Filter ratings are calculated using Minimum Efficiency Reporting values (MERV) which show the filter ability to absorb particles.

The merv rating consists of one to 16. MERV ratings have a higher efficiency and better filtering ability to capture particles in air.

Duration of use

The most useful reason for a new AC filter is the increased lifetime. Upgraded filters typically offer more long-term reliability compared to factory filters, so check this before purchasing any upgrade.


AC filters can be customized for any situation. While you may cut some in sizes, some are specifically designed for certain brands. Ideally, you should find the correct filter for the particular air conditioning system.
