After having picked up / having donated 4 different squirrel cage fans that just won’t work (rusted up, seized, bent beyond repair etc…) I have pretty much given up on building my own ambient air cleaner.

After looking around in the sub $300.00 price point, I found a couple of models from Penn State, Jet, JDS etc, and then this and a smaller unit from Grizzly. The G0572 seemed to have the best specs, 1 micron filtration, remote control, timer, and 3 speed fan delivering 556, 702 and 1044 CFM.

Grizzly presently has these on sale for $209.95, and that is just icing on the cake to me. Regular price is about $40.00 higher if I recall…

My only hesitation here is that I haven’t seen anyone talk about Grizzly air filters, and I have no experience with them.

Is this thing worth buying, or would I be making a $200.00 + dollar mistake?

I don’t have experience with them (I have an older JDS I picked up on Craigslist), but I can’t believe it matters a lot who’s air cleaner you buy. It’s a box with a fan – adjustments and accuracy don’t really matter. Grizzly doesn’t seem to sell much if any ‘junk’, so I think you’re very safe.

My unit has a washable prefilter, which is extremely convenient – this Grizzly and most others made now don’t seem to offer that.

You can always go the box fan + furnace filter route, too – I did that for a couple of years and while not as effective as my air cleaner, it made a big difference.

like mnguy – I have an older JDS unit I picked up on CL and it works fantastic. there really isn’t much to those units – they ARE a box with a fan inside with filters. as for specs- they should all be about the same give of take, but all do a good job.

check to see what filters each unit uses though – some have electrostatic filters (better) while others don’t. some have washable reusable filters, while others have throw-away disposable filters which can add to the total cost (depending on how often you use them will either raise the cost more or less).

I’d base my decision on the type and cost of filters that are available. the $40-$50 different in initial cost will soon be forgotten, and the addition in cost over the long run may not.

The primary filter is not washable, the secondary (the triangle looking bag thingy) is. I believe that the actual filter size is 18×24x1 for the primary, which is pretty common / available around here, I can get the Ace pleated filters in that size for about $5.00 per, so that would be okay.

I think I am gonna spring on this one…

I should mention, this is intended to replace a standard cheap 20” box fan and Filtrete Filter rig. Yes it is effective, but not effective enough as far as space usage… I want something I can ceiling mount and not whack my head on.

You’ve done your research – go for it indeed!

Later, if you find you are using a lot of pre-filters (unlilkely – you can always tap / blow them off), you can probably find a washable filter.

Good luck!

I have the Grizzly G5955 air cleaner and like it. I paid $175 for it last year.

We have two at work. You have to keep after them to keep them clean. As far as the motor and running they have worked well. Maybe too small for a small factory, but our bigger one gets dirty also. You just have to remember to turn them off, they are quiet. I would give it a thumbs up in a small workshop.

I just was looking at that cleaner too. Decided to google and got right here ;-)
I have one car garage shop for a hobby work and think about buying one too. Is it adequate for such shop?
Besides, I’d like to know about maintainence cost. I see that primary filter costs $9.95 and secondary (very fine) $17.95. How frequently I can expect to change them? I know it depends… but I woodwork as a hobby so not too much “work traffic” so to speak.

I have one and it works pretty good. But I think these over head filters should be used as a secondary approach to dust collection . The best approach is not to let the dust get in the air at all. If you don’t have a dust collection system I would suggest buying a HF 2 hp that’s on sale for $139.00 with coupons from a couple different woodworking magazines. Instead if running pipes every where I have three of these units that I’ve used for almost five years and they do a great job.

Yeah, I have the HF 2HP DC…. And I agree, this is just to get the stuff that gets missed by the DC. I am making every effort, and a couple extras to capturing dust at the source. But that effort isn’t 100% successful in no small part due to tool dust hood designs….

This waiting is sort of killing me. I ordered it on Aug 20, it was back ordered, but came in and shipped on September 3rd, and while it is interesting to watch the tracking as it SLOWLY makes its way from Washington state to Texas, it is also painful to wait. But then again, my shop isn’t ready for it yet (See my blog entry regarding cleaning up my wall for the lumber rack…). Simply put, the lumber rack needs to be in place, to get the remaining stack of lumber off the shop floor (long story). Once that is cleared, I have the access to the piece of ceiling I need… Now along with the air filter, I also need to run a 4” overhead DC duct for my Shark Guard as well… So much fun just getting things set up…

I am somewhat torn about the west wall though. I would LOVE to get the air filter in place, and the overhead for the Shark Guard run, but the down wall segment that will go along the west wall will have to be removable just so I can set the overhead up, but still be able to yank that sheet rock…

I need to start another thread on this subject, but I am wondering, what the best hangers to use for 4” S&D might be. Yeah yeah, I know I ought to be using 6”... I have 5” now for the DC and Thien separator, which splits after the separator to 2 4” runs… Not Bill Pentz approved, but it should work fine…

Not to make you feel bad but….
I picked up the Grizzly G0572 at the Grizzly tent sale last May.
It was new marked down to $50.00. There were about six of them.
The only thing wrong was the squirrel cage was out of center.
Rounded it back up and it runs like a charm. The remote is a nice feature.
The filter prices are reasonable for replacement.
It does clean up the air.
Even for $200.00 this unit is worth the cash. It is still a great price,
and I am sure it does just as well as the more expensive brand names.
Good luck !

No worries. I would have LOVED to grab a Tent Sale bargain light that, but alas… No Grizzly tents anywhere near me. Then again, that might be a GOOD thing… I could go broke in a hurry doing that.

I love Grizzly, I think not to long ago WOOD magazine rated a Jet the best over all. It maybe a bit cheaper also.

I had a G0572 for over 2 years now and it is worth the cost. The remote quit working after the first year, shortly after dropping on the floor which is not a terrible inconvenience since the unit is on the entire time I am in the shop. The replacement filter is rather pricey so buy an extra Primary 5 micron filter when you purchase the air cleaner due to shipping cost. So far have not found the filter size at the BORG yet.
