I'm actually a "fan" of removing filters - they tend to cause more
harm than good unless you're truly diligent about keeping them clean.
Many times in both install and tour environments have there been
overheating problems due to clogged and ill maintained filters. It's
better to let the dust flow through the amps and coat the inside a bit
rather than overheat them due to clogged filters. My old Crest Pro
amps have had the filters removed since they were new and are still
going strong. We just blow them out with dehumidified compressed air
once in a while for maintenance.

Thanks George and Mr. Liquidator. I had a look at kitchen extractor stuff
that Ron mentioned this afternoon, but couldn't find anything suitable.


Will Google for HVAC suppliers tonight.


Cheers,


Gareth,

You would probably be best looking on your local market, there`s usually
someone who sells appliance spares a lot cheaper than Comet.

ScotchBrite (the green stuff women scrub pots with) works great.

You can get it anywhere. The white variety is a bit finer-grained
than the ubiquitous green type. I've used it for years. It traps
dust just fine, doesn't significantly impede airflow, and it can
be rinsed easily when cleaning is required.
