A/C filters

Can someone who owns National Dolphin please tell me where to get a replacement ac filter for the house ac. I know it is located under the bed. Mine is a 2005.

Thanks for any suggestions.

Hello and . We are glad to have you join us here and we look forward to reading of your adventures and experiences. I am sure you will enjoy the website and forums. Good luck, stay safe and keep us posted.
Depending on the type of media the filter is made of, it may be washed if it is a foam type; or replaced if it is a fiber based material. If it is a fiber based, I would venture to say that any larger selection home improvement, department store and hardware stores will carry the size you need.

I'm not familiar with the filters used by National, but I'm pretty sure the basement air on Winnebagos with the filter under the bed use standard household air filters available at Lowe's, Home Depot, or other home improvement or hardware store.

If the filter is foam and doesn't have a cardboard or plastic frame, then buy the foam filter material for window AC units and cut to size.

I get mine at Home depot. Just take the old one out and measure it. I don't remember what size it is but i'm sure it's the same as mine.
