What are the air flow characteristics of this filter? Does it impede air flow, or does air flow through it freely?

I did not use it for a blower motor. I cut it to size and used it as a prefilter for my allergy HEPA filter. In that situation it did not impede the air flow at all. I also used it as a prefilter in my window A/C units. In that situation it did not impede the air flow either.

With any filter or filter material some air is blocked as dust and the sort builds up, but for the most part air flows through the clean material freely.

I am not sure what you mean by flow through freely but air does flow throw through the filter. I use them over my cold air ducts to collect dust and they seem to work fine and I have not noticed any problems with return air/funace. I change them once every 2 months this works great for sizing of larger cold air duct. Thank you.

I'm pushing 360 cfm thru mine no problem. It's i nice filter and doesn't hardly restrict air flow.

It restricts a little bit, not much though. If you find that the area your computer is in is quite dusty, this filter cuts down on so much dust entering your computer that it more than makes up for the little bit of air flow it takes away. (I have mine on a side panel blowing directly into my case. 120mm fan) I Highly suggest getting this filter if you have a dust problem. Just be careful when cleaning the filter because of tears and such.

The filter is fine. It catches anything you can see. When I am sweeping and see dust floating in a shaft of sunlight, I put the air filter in the room, turn it on full blast and come back 10 minutes later. The air is clear. Nothing floating in the sunlight.

If there is a reduction in air flow it is small. I haven't really noticed any. Just a big reduction of dust.

This is a question for an engineer, which I am not. However, I am/was a U.S. Goverment certified Engineering Specialist. I suspect this filter will not reduce airflow appreciably based on the fact I have had one for two or three years. I have noticed no loss of airflow in my one story home with full basement.

No. No air involved, just water. This thing attaches to an outlet. It does not affect what goes into the filter/pump.

if you are going to suck air in it would be better to use A freer flowing filter that would not clog up as easily as the Ven tech It is designed 2 capture particles internally. You can make your own filter or buy one on the market.

Sara - I seriously doubt that this filter would work for your particular application as it works on a "siphoning" principal which would mean that the intake tube would have to be submerged at all times allowing no air whatsoever to impede the flow of water. Additionally, the filtering unit must sit lower than the tank to work properly.

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...

I know the filter goes in between the grid, duh. Thats not my question. I have a green eco filter. What is the flow side?

free flow 471 (nothing attached), but will drop quickly with a load, bad choice to use on a carbon filter. It does pump up inflatable ducting much better than the 10" model. pretty quiet fan, silent if turned down a little bit.

It's the same principle as any air driven filter; the air pulls the water behind it. It's not a constant flow, the water comes out in spurts. There is also an option for an actual water pump.

I did not see a reduction in the airflow when I installed the filter. I did have far less fine particle dust once I installed it which was what I was looking to achieve.

John I would also like to know what it is. However, most of these types of filters I have seen generally have a rating of 3. It's about equivalent to the old fiber glass filters, low dust pickup but high flow. I have a 10x6x1 box (in addition to the others) in my house and it is IMPOSSIBLE to find an actual filter for it. Even the builder put in one of these types of filters. I've been here for 10 years now and haven't had any issues with my system or this type of filter for just this one.

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!

It's pretty easy to clean; don't know if you could easily rig up a filter that wouldn't impede airflow..
