Because I hadn't checked the ad and wasn't sure the Jet had HEPA
filters. Cheap filters (1u to 30u) are that price. A HEPA filter
could be that price each ($8 for Synfil, $9 for Filtrete.) A felt
bag would be under $30 and accomplish the safer filtering for the
upper price.

Do they have a way to mail order one? They don't seem to be selling
from their website.

$150 for a decne tair cleaner seems like a bargain compared to
building something of comparable capacity. A box fan does not have
anywhere near the air flow of a real blower, so while it may work for
your case, its never going to be as effective as the commercial unit.

OTOH if you can get a decent blower there is nothing to prevent you
from making something that would be as effective. The key is getting
a decent blower, the rest is reltively straightforward. If you can
find a used blower for free, its probably worth building your own. if
not, I would opt to buy something.

Having had experience with both, I can add this:

1. Any filter that allows the fan to move a decent amount of air
dosen't filter a very small particle. The fan will pretty much sit
there cavitating in the air within it's own enclosure.

2. The box fan needs to be placed super close to the dust source to
actually filter the air. Otherwise, it's simply dispersing the dust
with air movement and not actually removing any dust from the air.

I used a box fan for years while hand sanding radio control aircraft.
It worked OK if it was right on the workbench. The box fan *never*
caught up with the dust cloud generated by table saws, miter saws, or
router tables, especially with plywoods and MDF, and I'm only talking
about the airborne stuff my 2 HP DC didn't suck into the pipe.

The sheer amount of stuff that gets stuck in the filters of a Jet or
other store bought unit, as well as a properly made shop made version,
is beyond compare to what the fan captures.

Non-woodworker visitors even notice how fast the Jet clears my 24 x 40
basement shop. I like it so much, I'd like to get a second unit and
run them in a hurricane pattern. Two units would allow me to run both
on low or medium, they do make a lot of noise on high speed.

Barry

Yes, I bought one.

Just keep your eyes open for the next sale. I'm sure Eagle Hardware, or
whomever in your area will have sale.

HVAC squirrel cage motor: Free from most HVAC dealers.
(or use any household's in-stock 20" box fan)
Plywood: In stock in most shops, under $20 if not.
Tubatwo: tubucks from the Borg.
Switch: $1-5 from the Borg if not in stock.
Line Cord: in stock or under $2 from the Borg.
Filters: $8-30 a dozen.
Glue: in stock or $4 a pint from the Borg.

What's to buy besides filters, Al?

I would think that anyone willing to get their tools and remove a
blower could get one for free from most any HVAC installer. They just
sit out back until the trash hauler or scrap metel hauler comes along
to cart away those old furnaces. To me the value of the store bought
models is the nicer filter (they do in fact beat multiple layers of
pleated furnance filters)and the light weight (that sheet metal will
almost always be lighter than a wood case). The timer and remote is a
nice plus, too.

That said, my shop made unit moves more air, does not rattle and with
two sets of three pleated 16x20 filters does a good job of removing
the dust. Its heart is a 4 speed blower from a furnace out of a 9,000
square foot fieldhouse. I have the medium and high speeds hooked up to
a 2 speed switch. The filters are on the two sides of the box and the
air blows out the front. At high speed you do not want small pieces of
wood laying around in the wind's path ;) Clears my 2 car gar....shop
pretty quick. Too heavy to hang from the ceiling, though, so it sits
on top of a cabinet (its that 3/4 plywood I had sitting around when I
got the blower :)

My cost was $0 for the blower, $0 for scrap plywood (although it
could be done probably with a 1/2 sheet of CDX or something so count
$20), $6 for the switch and $0 for the filters (they come out of my
furnace periodically), $0 for the cord which I had around, but an
appliance extension cord for $8 to $10 would be fine and $10 for the
metal grates for the intake and outflow openings. So, assuming your
furnace uses pleated filters, you ask an HVAC guy if you can scrounge
the blower and you buy everything else you might have $50 in it. If
you have to buy the filters just for this, add another $20.

Well, as to the filtering capabilities of pleated furnace filters, I
believe the medium level Filtrete filters from 3M which I use (MERV 11
rated) are better than 1 micron. The upper level units are at .3
micron. See http://www.filters-now.com/ld3mspec.php#products and when
you stack 3 of those together and build a decent seal, it will beat
that $40 jet filter in stoping the dust.

As to whether asking someone if you can have something they are
throwing away is "panhandling", all I can say is to each his own. If
you saw someone about to burn some 8/4 10" wide 10' cherry boards
would your "pride" stop you from "panhandling"? I am not trying to
talk anyone into building an air cleaner and even stated that there
are real benefits to the store bought units. However, you most
certainly CAN build one that has as good or better functionality in
filtering the air for MUCH less than $150. Now whether you WANT to is
a different story.

Dave Hall

The problem with this setup is that a pleated furnace filter won't filter
down to 1 micron. It will capture large particles and recirculate small
particles. The large particles are what settles on your tools. It is a
nuisance but is otherwise harmless. The small particles get inhaled and
collect in the lungs. They are the problem. By recirculating them, instead
of allowing them to settle, the situation is made worse.

An replacement inner filter from Jet is $40. That leaves $110 to buy a
blower, and the other parts.

I stand by my statement that you cannot build a comparable one for $150
unless you already have many of the parts, or know where to get them for
free. None of my friends are HVAC contractors and I have no intention of
panhandling the HVAC companies in my area.

No need for pictures, but I'm curious how much you paid for the blower and
the inner filter. I suspect you either already had the blower (perhaps from
a old furnace), or knew someone who would sell it cheap. Just try and find
an affordable unit (either used or surplus), of comparable power, on the
open market.

I consider the remote control and timer on the Jet to be a luxury so I
wouldn't expect to find them in a home made unit.

I'd like to see someone try to build something of comparable capability for

==================================
I've got a big blower that came out of a 3-ton Carrier central heat/air
system that I saved when I upgraded my inside unit. I was thinking of using
it as a heavy duty fan for my shop until I saw this article. That thing can
really move the air and is very quiet.

David S.

Are you sure about this? Amazon and Rockler are asking $250 for this unit.
And there are no Menards in California, where does that leave me?

Filtrete filters are HEPA certified. Why do you say they're
useless?

True, but they will filter air for the budgeteers.

I can't see why anyone would opt for that expensive type of
cleaner when they could have fun by building one much more
cheaply. That said, I tried a furnace filter on the back of
the 20" box fan and it, er...sucked--Not much flow. 4 or 5
filters in the shape of a box might be enough area to reduce
the drag, though.

While building one could be great fun, it takes up valuable
wooddorking time.

Few homemade machines would have variable speed, timed shutoff, or a
remote control, all features that I've found useful. If they did,
they'd probably cost more to build than buying the Jet unit. Also,
many of the shop made units seem to focus on "found" blowers. Paying
for a blower changes things significantly.

Not everyone is looking for another construction project when they want to
filter their air. For $150, they get something with known performance
characteristics and they get it now. Some people have limited time
available in the shop and might want to spend it making sawdust instead of
an air cleaner. That said, I built one from a blower my neighbor the HVAC
guy gave me, which works fine with the small exception that the blower is
going out (could be why the furnace it was in was replaced). No worry,
though....he can get me another one.

You'd be much better off with a HEPA-filtered DC for that.

Standard filter bags, no doubt.

Not everyone can afford $400 worth of filtering equipment on top
of their DC purchase, Barry.

The 1 micron inner filter is $40. Furnace filter are useless--see my
previous post.

I don't know any HVAC contractors and I will not panhandle a blower from the
HVAC companies in my area. So that means buying a used or surplus one.

Regarding the box fan, it has no where near the air flow as the Jet.

No, the stuff that comes off the top of the tools, especially saw
blades. It never goes down the pipe.

I didn't believe that was the issue. I was under the impression that
we were discussing if a fan and furnace filter were anywhere
comparable to a squirrel cage unit, purchased or shop-built.

One $150 unit does great, the only reason to add a second is to get
the same performance at a much lower noise level. No one ever said it
was necessary to spend $400 to filter the air.
