After easing the fan away from the main body I seem to have cured the squealing noise. So with that problem, hopefully, solved the last thing I wanted to make was some sort of induction filter; this was made from cutting up a surplus car air filter, the wire gauze that you see on the outside is normally on the inside with the foam wrapped around.

I tried it out first without the foam in place and then with the foam in place, there was no difference in how the heater ran, just a lot quieter from the intake.

Though it's a free flowing filter I made sure it was glued on the inside and around the outside. I used a hot glue gun and it seems to have done quite a nice job holding the foam to the plastic.

Last picture shows the finished article. Never to be seen as it's tucked behind the driver's chair nearest the wall. Hopefully, now no nasties will be sucked into the fan.

Make sure you clean it out regularly ....if dust/lint etc builds up ...
You may end up with overheating problems and a damaged heater .
