Hi,

That's a very good idea, but only if you clean it very well. The thing about a Filter is that the more used it is, the better it filters but the more restricted it is also. The debris you can blow off is usually only on the surface of the Filter and not the stuff captured between the Paper fibres.

The downside to this is that it makes your AC/Heater Blower work harder because it will encounter greater resistance as it tries to suck the Air through the clogged/partially clogged Filter. This can lead to premature Burnout of the Motor or accelerated Bearing wear.

Considering that the Blower (PN# 996 572 903 00) retails for $370.00, this can be a False Economy. You can buy a lot of Filters for $370.00 - Your Call...

Happy Motoring!... Jim'99

As the air filter becomes blocked, the amps that the blower motor draws drops. I lost a bet with a HVAC repair man over this issue!!!

I wouldn't believe it until he hooked up an amp meter.
