Dayton HV120029G Filter

The Dayton HV120029G is a replacement air filter designed for HVAC systems in recreational vehicles. It fits equipment identified by Grainger item number 4RNN9 and is sold in a package of four. RV owners and maintenance technicians use it to maintain airflow and protect internal components from dust.

Sustained filtration performance

The filter traps airborne particles continuously while the ventilation system runs, preventing debris from accumulating on coils and fans. A four-pack allows scheduled change-outs so that restriction stays low over the entire season. Regular replacement keeps the blower motor operating within its design limits.

Build and mounting practicality

Each filter is built to the dimensions required by the specified Dayton housings, so it seats without gaps or bypass. The cardboard frame resists moisture from condensation during normal RV use. Installers simply slide the filter into the existing rack, with no tools or adapters needed.

Questions about this item

How much airflow noise does the Dayton HV120029G filter add when the RV air-conditioning runs continuously?

The filter uses a low-resistance media designed for steady airflow, so it adds negligible noise even during all-day operation.

Which specific RV air-conditioning unit must I already own for the Dayton HV120029G filter to fit correctly?

It is made to fit the Grainger item 4RNN9 Dayton air-conditioning unit; verify that your RV uses that exact model before ordering.

Will the Dayton HV120029G filter work with the original factory air-conditioning unit in an older RV?

Only if that factory unit is the Grainger 4RNN9 Dayton model; otherwise the dimensions and mounting tabs will not match.
