Filters are designed to absorb contaminants and keep the foreign debris away from operating components. One way to assure maximum service from the various operating systems within the RV is by following the component manufacturer's recommended filter change schedule. You can find information regarding filter changes by reading the owner's manual, particularly sections pertaining to preventative maintenance. If your unit did not arrive with the operator's manual, contact Technical Publications at (800) 634-0855 ext. 8163.

Maintenance recommendations are generally designed for normal operating conditions of the RV. When traveling in severe conditions, the filter schedule may more frequent attention. Severe conditions include extreme temperatures, driving over dusty roads, towing large trailers, frequently idling the engine, or regularly driving up and down mountain passes.

Some locations in the RV that may require filter replacement are the main engine, transmission, generator, fuel system, and fresh water. Use quality replacement filters that can guarantee protection against infiltration of damaging debris into the system. Don't attempt to save money by recycling a non-reusable filter. Attempting to clean the disposable filter by blowing away debris using air or water will weaken the filter and lessen its ability to protect the related component.

The air conditioning system in the RV includes a filter in the ceiling unit that does not require replacement, but should be frequently removed and cleaned. Wash the air conditioning filter using mild detergent and water. Allow the filter to air dry. Do not operate the air conditioning units with the filters removed. Plan on washing the A/C filters at least one time each week when traveling with pets.

Before changing filters in the engine, transmission, fuel system and generator, turn off the engine and engage the parking brake. Gather all the necessary tools needed for filter replacement including clean rags, a drip pan, filter wrench and the new filters.

Keeping track of filter changes can be valuable information when troubleshooting potential problems. Recommended filter changes can be based on mileage, hours or time frames. A good way to keep track of filter changes is by writing the date of replacement on the filter housing using a black marker pen. This will make it easy for you to determine at-a-glance when the filter is next due for a change.

Following scheduled filter changes will help you to save money, as in the case of fuel filters, which can help promote better fuel mileage. Travel with spare filters to avoid having to track down parts while you are away from home.

If you are in the market for a used motorhome, take into account the last time filters were changed. Replacing multiple filters may justify adjustment in the selling price.
