Cougar Heater Filter

I have a 2010 318SAB and was interested in changing the filter to the gas heater. I couldn't find one. Does anyone know if there is a filter for the heater return? Thanks.

I'm not aware of any RV furnace that has a filter in any of the air returns. Are you thinking about a filter similar to one that you would find in a residential stick-house furnace?

RV furnaces are not designed to incorporate filters in their circulation system and you would be inviting problems if you were to restrict the air flow by trying to install one.

Thanks Festus. Yes, that's what I was thinking that there would be a return air filter. Good to know there is none.
