the concept looks easy enough, my thought was take a couple of high
filtration furious filters like 3m's filtrete, stack them 3-4 deep put a
squirrel cage fan to pull are though and mount this on my garage ceiling,
the one big problem is the filters are a little bigger then I would like
16x20x1, anybody have a better Idea?

Regular furnace filters on 20x20 fan boxes work pretty well. One on each side
is best. I tape them on, others get fancier. The incoming side nasties up
fastest. Peel, toss and put the next 99 cent special in place. After a couple
years, the fan motor gives out. Spend 14 bucks for another one.

I've seen regular furnace filters as small as 12" x something or other. That
should work on your squirrel cage blower.

I got squirrel cage and 2 speed motor from plumber when they installed
a new unit. Cost $8.00USD for switch.

There are pretty good plans in the book Controlling Dust In The
Workshop© by Rick Peters. I built one with a three speed 1/3 hp blower
motor with squirrel cage. (the plans call for a 1/15hp motor)
Therefore, everything had to be upsized to fit the blower housing
inside. Fortunately, the filters cost the same irregardless of size.

Furthermore, there was a discussion was going about switching the
different speeds about a month or so ago,. Someone suggested a on/off
switch and two three-way switches. Thats the way I went and it works
very well.

Not a set of plans but enough info to build one that fits your needs -
an outfeed table / downdraft sanding table / ambient air cleaner
which uses an old furnace squirrel cage blower and some pleated
cartridge filters - diesel truck filters work pretty well.

Mine are 14 x 25 stacked low filtration (for chips) high filtration then
a high filtration pleated cloth bag type. I built
it into a table with holes in the top so it can also be used as a
sanding table. Air exhausts downward under the table. It has a double
squirrel cage making it a lower profile.

I believe the combined surface area of the filter including the folded
area needs to be large enough in order to ease the air flow.
Therefore, a large filter may not be a bad idea. You may want to look
up a dust collection book to look for the formula to determine the
right size of filter for your blower.

If you really need it to be low-profile, I think you can use two or
three filter cartridges (that normally use in a shop vac) to get the
same filter area in a very low profile. But they probably cost more
and the way to mounting them is more complicated than regular filters.
And the "cost more" part "probably" defeats the purpose of making an
air cleaner yourself instead of getting a store-bought one.
