I don't know if anyone else has had this problem but every RV I've ever owned has been incredibly dusty inside. And it seems to start when their new because there is dust and sawdust in the trailer as soon as I get it home and it doesn't get any better as the trailer gets older.
I can live with a little bit of sawdust shaking out of the ceiling every once in a while because I understand when they build these things there's going to be sawdust inside the walls and ceiling and sooner or later it will find a hole like a light fixture and come out, which would also happen to a sticks and bricks house if you pulled it down the highway at 60 miles an hour.
It's really the dust that bothers me the most because it covers everything especially my computer screen, and wiping it off of everything doesn't last very long before it covers everything again. And since I'm not a housecleaning fanatic it wouldn't break my heart at all if the dust just disappeared and never came back.
I realize that some of the dust is built into the RV with the bedding, and the carpeting, and the sawdust but some of it must be coming from the outside and I guess boondocking in the desert doesn't help the problem at all because the desert by its very nature is dry and dusty.
After giving this a lot of thought I decided that I would try doing something different than just moving the dust around with a rag and went to Walmart and bought an air filter.
Now I don't know the first thing about an air filter but I know the word HEPA has something to do with it so I bought the air filter that mentioned the word HEPA the most times on the box figuring that the more HEPA a filter has the better it should be.
One of my concerns about an air filter was can it be used while boondocking without running down the batteries unnecessarily, and it looks like the answer is yes. The owners manual says it only uses half an amp an hour on its highest speed which is not enough for me to worry about.
The filter I bought is named Thera Pure, and it cost about 70 bucks, and not only did it have more HEPA's than the other guys but it had a permanent filter in it that you could clean and reuse, whereas the other guys had a filter that you had to replace every once in a while that cost about half as much as the whole machine! The old Boondork may be a few fries short of a Happy Meal, but he's not a fool.
