AirFeel RV AC Filter Replacement 7.5 x 14 in — 3-Pack, 3-Layer Carbon & Polyester for Dometic Duo Therm (Replaces 3313107.103)

Keep your motorhome, camper, or travel trailer comfortable and running efficiently with AirFeel's 3-pack of 7.5 x 14-inch RV air conditioner filters. Each filter combines a silver-reinforced pre-filter, a dense polyester core, and an activated carbon outer layer to reduce airborne debris, catch fine particles, and help control odors. These replacements are built for direct compatibility with Dometic Duo Therm models that use part numbers 3313107.103 and 3105012.003, and they install without cutting or complex modifications.

How does this filter protect my RV’s air conditioner?

The AirFeel filter reduces the amount of dust, pet hair, lint, and other particles that reach the evaporator coil and blower motor, which lowers the chance of buildup that can reduce efficiency. Less debris means fewer service issues and more consistent airflow, extending component life when you’re using the A/C for long drives or extended camping seasons.

• Silver-reinforced outer pre-filter catches larger debris and resists wear.
• Polyester fine-core traps smaller particles like pollen and fine dust.
• Carbon outer layer helps reduce cooking and road odors inside the cabin.
• Designed for direct-fit installation with no cutting required.

Will this improve cabin comfort during travel and camping?

Yes—the carbon-embedded outer layer helps neutralize common RV smells from cooking, pets, and traffic, while the multi-stage media reduces airborne irritants that can make the cabin feel dusty or stuffy. The breathable construction balances filtration with airflow so your A/C can still move conditioned air effectively.

• Activated carbon reduces transient odors for a fresher interior.
• Multi-layer filtration lowers visible dust and small particulates.
• Permeable polyester core preserves airflow for cooling performance.
• Sold in a three-pack—convenient for seasonal or multi-unit use.
