Is there any air flow restriction from filter?

The filter has an air resistance rating of 0.12" WG. That's about the same as a good pleated filter.

Unfortunately, I cannot say. It seems that certain versions of the air filter do take different-size filters possibly because the filtration processes are slightly different.

I didn't use it for a filter,I used it for a inline A.C.duct that wasn't blowing hard enough. Even then the fan was not strong enough to make a noticeable differance,will try larger fan.

You will be fine. I have 1 sponge filter that is missing clear top piece. So if you want a wide dispersal of air bubbles just take it off.

Not a lot of restriction but is is finer then most filters, which in turn will collect a lot more dust. To be the BEST filters ever. When I see getting dirty I just clean it. Magnet works perfect, I have bought 3 of them.

I've not seen any. I have, in a pinch, overlapped and tied the filter to a tall mug or jar, though it is a PITA to do so.

No! Unless u run your a/c all day with the bottom vents open provided u have enough NEG pressure on your fan/filter combo... Hope this helps!!!

Whatever place you put it, be sure it is secure. It should also complement air flow for dust collection and heat or ac sources? My concern is also access to changing the filters as they clog? It's an odd size filter. I'm considering making a pre filter frame to use cheaper filters from the box store. Good luck, be safe!

On the front there is a panel that hides the filters, the air comes in around that panel - it's about a 1/2 inch of space all the way around the panel that allows the air to come in. The air is sent out via the top of the unit.

Once I applied this in line filter, it drasticly reduced my air pressure. So I just canned it. I apologize for bit directly answering your question. But it's somethig I wish I knew prior to purchasing this item

There is no filter ... you could open the lamp compartment remove lamp and visually inspect to see if any blockage of air flow, but if there were overheating there is a warning lamp on top of unit which should be blinking,red i think. Otherwise idunno...

As far as I know no there are no filters. But my fan is having problems running already. If you have not already bought this fan don't buy one.

Had no problems with mine. You may not have twisted the filters back into their fully seated positions.

No, no problems whatsoever. Maybe you should reinforce it with a little bit of scotch tape around the part inserted into the filter base.

I can't remember if I noticed any reduction, however, it's probably a good idea to clean the filter every once in a while to remove the small particles that lead to a blockage. I can say I noticed a considerable amount of less airborne dust in the shop.

Yes it is it is a low restriction filter allowing more air easier. Be sure when cleaned to use the oil on it to help trap the dust. Excellent product have been using for over 20 years.

it depends on the volume of air that the filter will flow. look at the cfm on filter and should be greater than the cfm on the fan.
