Top Tip for anyone who runs into problems with the manual door locks after inhibiting APS as i did. I inhibited APS then locked myself out of the car and found out the hard way that my key lock wouldn't open the door again. If you open and close the charge port flap 10 times the APS reactivates and the doors will function electronically again. Obviously don't do this with connectors off at the rear.

I drive the suburbs of Rochester NY, no country roads or dirt to compromise my paint job.
I take it out every other weekend for a coffee run, or dinner, movie, etc.
Unless I'm incorrect, it sounds like once a year should suffice.

I would be more concerned with this media restricting airflow, especially in a dusty environment.
Having opened up the PEM, I was surprised to find that the airflow does not actually run through where the electronics reside, just to the heat sinks.
The electronics were spotless, not even a hint of dust.
If you clean regularly (I do it in the late fall after leaves are down and gone) you should not have any problem. In fact, if you diligently watch your PEM and motor temps you may not have to do it annually.
This media has almost 0 airflow restriction. I'll watch my temps and compare to my other Roadster.

I used household air filter material (eg from Publix) over the huge holes in the wheel arches (where all the road dirt is sucked up from) ... keeping Fans, PEM and motor clean for nearly 3 years with no temp increases. The aim, apart from keeping cr*p out, was to extend service intervals - as the plugs and sockets on the PEM are a weak point I want tp minimise the risk of multimple PEM lifts / connect+reconnects of fan cables etc: here is the guide: Roadster Rear Blower Maintenance
So many engineers types on here
3M filtrete washable....reduces static pressure by .05IWC at 615CFM. Our fans are 625CFM each. Filter can flow well over 2100CFM.

Blockage = Crap / Area (
sorry, couldn't resist that 'engineers speak' )Ha ha....sounds about right. I'm not so conerned with PEM as I am the motor since the PEM has gravity to keep fins clear. The motor seems to accumulate a lot of junk up top.Blockage = Crap / Area (
What some have done is put a screen and/or filter around the outside of the blowers, under the rear of the car. The filter material used for "swamp cooler" air conditioners, or similar has been mentioned. Putting the screen / filter there also protects the motor fins, which also like to collect debris, and the blowers themselves. One needs to be careful not to obstruct too much of the air flow, however.

here's my (...unfinished) version of a filter for the blower (my car: 2009 roadster 2.0)
behind the grid there'll be filter-sheed for kitchen range hoods - i believe this will allow
maximum airflow and be sufficient enough to prevent the worst road-dust in my PEM/
engine.
only issue is that to clean the filter you need to dismount the blower :-(

Even better tip: leave the window down, reach in and open the door with the interior handle.

Its easy to do both, to be honest you're going to have to take off the stablising bar (at least the mounts you can leave the drop links to the suspension in place), to get the fan unit out - well thats the dual unit but I'd assume similar
?Anyway it's dead simple to get the unit out, inspect it (check for rotation ease, absence of debris, no burn marks on connector etc), and then get it back in. I'd personally mark the shims for the anti roll bar to mitigate any misalignment issues to each side. Adding a filter as many have done seems dead simple also, the biggest two concerns in my view are a) ensuring sufficient airflow for what isn't a particulary effective solution in the first place, and b) using a material which doesn't distintegrate and subsequently blocks the air feed even further!
Got plenty of pics when I switched units in my own, and another Roadser local to mine. Probably the easiest maintenance to do on the car.
