I frequently camp in dusty places. I asked Mr Google... Couldn't find what I'm looking for. I'm looking for an air filter I can put in my FanTastic, (or in my bathroom vent) whether it's top or bottom loaded, that will filter dust and then create a clean, positive air pressure in my TC.Think the air filter you would put in your home furnace intake.I'm almost thinking of taking one of my home filters and cutting it to size, then a little engineering-spec multi-purpose adhesive (duct tape).

DIY.....make one and see how much it blocks airflow.Think they would be 'restrictive'Now--A cheapie foam filter like ones used on RV A/C Return Air MIGHT work

I do not know how helpful this is, but have you thought about an air filter for a car or truck. They come in various sizes and you would need to get something close to the size you need then put it in place (on top or underneath the vent) with your engineering-spec multi-purpose adhesive. I do not know how restrictive these filters are either but it should be relatively cheap to try. Good luck and let us know what you do and how it works.

Household filters are not design to stop fine dust. If you really want something good, I ditto automotive filters idea. I had severe duty air filter in my older Ford, that could hold almost 3 lb of dust before triggering service light. Not going to be cheap, but cheaper than hospital bills.

Many (many) years ago I took my EuroVan Camper to Burning Man. If you haven't been there.... well, it's the very definition of "dusty place".Anyway, I did exactly what you are describing; I made my own filter using a large cardboard box with 5 pleated-paper HVAC filters duct-taped to the outside of it. I used the finest ones I could find, then I wrapped the whole thing with several layers of tacky-backed air filter media from McMaster_Carr as pre-filter to prevent the paper from clogging. A couple of bungees to pulled it down snug against the roof surface.I ran my Maxx-Fan for vent on the intake setting 24-7 which kept the interior of the van positively pressurized just enough to keep the dust out. At the end of a full week out there I had no dust in the van's heater vents, window sills, door gaskets,etc. I was amazed at how clean the inside of the van stayed.Hope this at least provides some food for thought.Cheers,-Mark

I have one. Took it off and hosed it down after each trip. I don't think it will fit on the new Fantastik on the new BF.

FAIL. Nothing.

It's probably been 10 years ago I remember seeing filters, because I wanted to install one in the Maxxair fan on the Desert Fox toy hauler... but the filter would only fit Fantastic fans... I remember that detail specifically.

Yes, I remember Maxxair used to make a filter for the Fantastic fans.

Looks like the higher model fans are reversible.

Does your fantastic fan pump air into the camper? Mine is an exhaust fan. You would have to create an air inlet duct with a filter on it if they are exhaust fans.

since he wants a clean positive pressure in the RV, I would "assume" that it is reversible???? wouldn't make much sense to have the filter on the exhaust side.

Maxxair used to make a pop in filter for the fantastic vent, but it looks like it is out of production.

I have a furnace filter that is sort of interwoven plastic threads??? that you can cut to size. don't really know how to describe it. I wouldn't go the HEPA filter way unless you don't care about air flow or motor burnout.
