Furnace Filter

[CRUZIN 2]

Does the furnace have an air filter, ours don't or is that the way they are? I think there should be one or would it be hard on the fan motor? Larry & LaVonne

No filter in ours. I think the manual says to not install one as it will adversly affect the operation of the furnace (or something to that effect).

none here.

In our previous trailer, I cut and placed a piece of black filter material like in the A/C behind the return air vent. It did catch a lot of "stuff" without affecting the airflow. I also cut and placed fiberglass screening in each of the floor registers to prevent "stuff" from falling in !

Being in the hvac business,any furnace builder that does not include a filter is asking for trouble,,or as in this case imo parts sales.Adding a filter is a must.I know of not one rv furnace manufacturer that includes a filter but to say a filter will adversely affect the furnace is crazy.That is one of the first things we added, built a small filter rack and installed it behind the return grill on the fiver,only use the cheap black window a/c filters but that is better than nothing.A plugged filter can cause major adverse affects on the furnace so it must be attented to,also the a/c filter.But no filter will allow airborne particles to enter the motor cooling rings,the blower,and the heat exchanger thereby allowing extra heat to build up, less airflow and thus,new parts are needed.I would rather clean a filter once in awhile and protect the unit than change furnace parts after a few years.This is by no means a knock on keystone as like I said before, no rv furnace builder in any rv we have owned,atwood and surburban;has included a filtering system.Real simple job to do yourself and gives me peace of mind,but just my 2 cents worth.

We certainly appreciated your very informative messages on furnace filters. I had planned to put one in but just wanted opinions from others before I did it. Thanks Larry & LaVonne

The filter would be better located on the furnace itself. I know our furnace is located in an area that can not be accessed easily to install a filter on it. By installing a filter at the grille may help a little, it will not protect the furnace completly because it is not ducted to the grille.

Our 2001 2955RL was going to get one installed one day and low and behold there was one already in there behind the furnace grill. Came from the factory that way.
