Does this decrease air flow over the #201 setup ?

I don't know. Never thought about it till now. I didn't notice any difference after I installed this new one.

This does not reduce the air flow on your furnace. If anything, it may increase it. Good product.

I have not noticed any decrease in airflow, but I have not done any measurements. I'm sure Aprilaire could answer that question.

I haven't noticed any decrease in air flow. The upgrade kit and new filters make a tremendous difference in the air quality of my house - especially the allergens. Very clean.

I have no idea if it decreases air flow. I would not even know how to measure that. I have purchased my second filter replacement fore the newer setup and I am happy that it is so easy to install versus the older setup where we had to mess with those ribs.

There is no noticeable reduction in airflow until the filters need to be changed

No, air is drawn in to the unit through the flat mounting surface on the back. The round interface shown in the photo is for the return only.

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

It should not restrict the flow. You want to filter your outtake fan? Typically you want to filter the air being sucked into the case. FYI, a good way of reducing the amount of dust in your case is to make sure you have more total filtered intakes then you do total outtakes. This will create a negative pressure in the case.

Not significantly. If you are looking for a quiet solution and are somewhat electrically savvy, try wiring two fans in series and ditch the speed controller. I found this configuration was much quieter (practically silent!) than using the fans on the low setting of the speed controller, and still moved a surprising amount of air. The speed controller is not a very "elegant" design, and causes the fans to emit a buzzing or humming noise at low speed.

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

No, we were told that it should be fine by our heating and cooling installer. However, if it is a a lit of the fins, it can affect air flow. I would check with your installer to be safe.

I have not noticed any difference, I don't know technically if it does. I have not found any where that has allowed air to pass being that it had pulled away . I was just running new water and sewage lines in the basement and was inspecting for air leaks of places that I missed on the original install. I found none. You might want to contact the manufacture for technical data. They were very helpful and addressed all questions. I used the closed cell exclusively . Full fill . I can tell I am BLOWN AWAY with the low cost of my heating this year so far. I have used only 1/4 tank of oil. I keep that house at 70 degrees. I live in western pa.

It sounds like you need to adjust the regulator. There should be a black knob on the regulator that you can pull out then turn to increase or decrease the air flow.

Yes air should move enough and is quiet running. I would ensure vent in/out hole was there.

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.

Slight airflow is normal. The unit is not a fan, but it must circulate the air a little in order to clean it.

I have both the 3 blade and 2-blade fans. The 3 appears to move more air, but not so much that I notice the difference in room comfort.

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.

No. The sides are where the intake vents are located. This would cut the airflow in half and make the purifier not as effective. It also would be really unstable as the sides are not square.

I have two of the double fans (total of four fans) mounted at the top of a closed closet (3ft wide, 7 ft tall) which houses our computer servers and security system hardware. I reversed the mounting on the fans so they are exhaust, blowing the air out of the closet. There is about a 1 to 1 1/2 inch gap at the bottom of the doors where air can be drawn in. The idea is hot air rises and is exhausted while cooler air is pulled in at the bottom. This seems to be working quite well over the past month or so since the install.
