Anyone know where to find the foam material that is used for filters. The kind
you would use behind computer fans and the like to catch dust. I need to make
some custom filters for a few 120mm fans, Is there some place that sells it by
the sheet or rolls?

DIY stores sell it for cooker hoods. About 5mm thick.

Hardware stores often have sheets of open foam filter material for air
conditioner filters. It's a couple square feet, about 1/8" thick, and
easily cut to size with scissors.

That's exactly what I use.

My PC tower had two fans - an extractor at the back (for the PSU at the
top of the tower) and a 'sucker-in' a bit lower down. I turned the lower
one around so that it was also an extractor, and added a 'sucker-in' on
the front (the case was already drilled to take a fan). I then blocked
up as much as I reasonably could of all the other holes and slots in the
case, the idea being that the only way for the air to get in would be
via the front fan. Finally, I jammed a piece of pan scourer (about 5
inches square and 3/4 inch thick) between the plastic front cover (which
has some fancy vents hidden near the bottom) and the part of the front
of the case where the fan is.

Every couple of weeks, I simply pull off the front cover, remove the pan
scourer filter, and remove the dust (and then, of course, replace it).
The amount of dirt on the filter is absolutely unbelievable.

You need fairly open stuff od the airflow will be impeded.

Do you mean this which I've used in power amps a lot (mainly present a nice trim
to cooling slots).

Thanks, I will call around. I was rattling my brain trying to think what types
of industries use filter materials like what i am seeking and range or stove
hood vents was something i had forgotten about.

What i am looking for are sheets or rolls of this material. This company has
what i sort of need but they will not sell to non corporate customers. I need a
slightly larger size.

You might try industrial supply on 3rd west and 17th south. Try some of the
sewing supply or arts and crafts stores for sheet foam rubber.

Google 'reticulated foam'. That's all I did. There seemed to bevarious sellers other than the

I can walk into the local Grainger's store and buy anything they
sell. I am not in business, or even able to work these days. I tell
them what I want, they enter it into the computer, pull the items from
stock, add sales tax and I hand them the cash.

Try www.mcmaster.com Go there and search for foam air filters, or just
search for foam and scroll down to foam air filters. They have
polyurethane open cell foam in thicknesses from 1/8" to 2" and various
cell coarsenesses (is that a word?) Sold in 48" x 72" sheets. They
even have a sample pack of different coarsenesses so you can choose
which you like.

They accept credit card orders from anyone and their shipping prices
are VERY reasonable. And shipping is QUICK!

If you just search for foam, you'll find LOTS of possibilities, but
scrolling down to foam air filters will probably get you what you
want.

And use the vacuum cleaner motor to pull air through the high

Did you look at the (cheap) furnace filters? Most HW stores sell the
very cheap fiber filters (e.g. blue or green fiber) for something like
$2 for a 20"x20" filter. You can take one of these apart very easily
because the frame is cardboard. The filter material is not very
restrictive to air flow. If you need more filtering capability, just
double the filter thickness. Things like vacuum cleaner bags and
exhaust fan filters are usually more restrictive to airflow because they
have the luxury of a very powerful fan motor and usually a high flow
rate. Fan flow rates for PCs are (usually) very low, e.g. 50-80 CFM, so
you don't want a filter that will be a high resistance to airflow.
