Buying Guide: How to Choose the Best RV Air Conditioner Filter

Choosing the right RV air conditioner filter depends on several key factors to ensure optimal air quality and system longevity:

  • Filter Size and Compatibility: Measure your RV air conditioner filter slot. Some filters, like the CCBASEBALL or PJT models, come in large sizes and can be cut to fit various AC models. Confirm compatibility, especially if you have a brand-specific unit like Dometic or Coleman.
  • Material and PPI Rating: Filters with higher PPI (pores per inch), such as 50PPI, offer denser filtration to trap finer particles. Lower PPI, like 40PPI, might be less dense but often reusable and washable. Choose based on your need between filtration efficiency and eco-friendliness.
  • Reusable vs Disposable: Washable filters like the PJT and Dianrui models provide long-term savings and reduce waste. Disposable filters often have higher initial filtering capability but require frequent replacement.
  • Thickness: Thicker filters (0.5 inches) can provide better filtration and airflow balance but must be suited to your AC’s slot depth to avoid fitting issues.
  • Quantity and Value: Multi-packs (such as Acostop’s 6-pack) provide convenient spare filters, especially useful for frequent travelers or those with heavy AC use.
  • Filtration Efficiency: Look for filters effective against dust, pollen, pet hair, and smoke to improve your RV’s indoor air quality and protect your AC unit internally.
  • Ease of Installation: Simple replacement filters reduce maintenance time, important on the road.

By considering these factors and matching them with your particular RV air conditioner model and travel habits, you can ensure a fresher, cleaner environment and prolong the life of your RV’s cooling system.
