New owners should know how to replace an air filter in a travel trailer. Most travel trailers have an air conditioning system, and part of that system is a filter. The filter traps particles like pet hair and other material that float around in the air. This prevents a clog up in the cooling fins, which the warm air flows over to be cooled.
To replace an air filter in a travel trailer, you need:
- Find the air conditioner in the camper. Most systems are ceiling mounted. There may be two units on larger campers like 5th wheels.
- The filter panel should be accessible from the bottom of the air conditioning unit, near the controls. Look for protruding tabs around a plastic grill.
- Gently press the tabs in and the grill should swing down. Be careful as you press so you don't break the tabs.
- The air filter is usually a black or gray foam type material in the shape of a square. It might slide into rails on the removed grill or it may just lay on the grill.
- Replace the air filter with the new one if the old one can't be washed out with plain water. The filters are somewhat delicate so be careful with it.
- Put the grill back in place. Remember to gently insert the grill and watch for the tabs.
Test the air conditioner after the filter is re-installed. Look in your owner's manual for more specifications, or find the manual online at the travel trailer manufacturer's website.
