Does this filter reduce air flow ? If yes, how many % air is reduced?

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

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

Not much at all...10% if that much. Still have lots of air flow....can hardly tell. Use in daughters room who has asthma....cut down on her symptoms immediately.

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

It's a pretty good sized filter- basically the whole handle- and very fine. I don't think it will let any particulates through. I've had to pop it out and rinse it a couple of times when I noticed flow decreasing. It's very easy to do.

Not sure. I took mine off seems a little cheap and seemed to restrict air flow. Put your money in to a nicer one.

I have a fairly powerful unit so I did not have a problem with the filter. It is pretty dense so it will reduce some of the airflow. But on the positive side, its easy to keep clean and reuse.

Agree with Tepple. They are referring to the intake of contaminants, NOT the intake of air. You can still breathe easily through the filters, although as Tepple said, they do limit the intake of air a little bit, as any sort of filter would. But not enough to feel restrictive or problematic.

My vents are made of plastic and the the part that controls the air flow can be unsnapped. I remove the air flow control part and place the filter sheet in the main vent and then snap the air control part back in. That keeps the filter in place. At least that works for me.

Yes, the filter is in the unit. Air escaping from the rear is proper. That is the air being vacuumed up in the front, catching the debris going thru the filter and passing out the back of the unit.

That depends if you need the full 435cfm. The filter will reduce the cfm after it has done it's job which causes drag. So in retrospect running the fan at full speed or slightly under is recommended if that is the amount of air you need. So to put it a little bit more simple, your phresh filter will probably reduce about 100 cfm from the power of your fan. If you ran you fan at half power you would have a total of about 117.50 cfm. I recommend full speed or a little lower. If that's not an option, buy an 8" one, that's what I did!

I honestly don't notice a water flow reduction - and if there is one it is not close to 1/3. I have owned this brand/model for many, many years (I am currently using 5 of them) and when one goes bad I definitely notice the reduced flow rate. For me, the convenience of having these timers far outweighs the infrequent problems that I have with them.

It may restrict the airflow, the problem is: it gets clogged with dust quite fast and you need to keep an eye on it, I usually clean it like once a week and I take the filters out when I'm playing a heavy game because you need a lot of airflow during that time.

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.

Yes , mine has been driving one filter for a year just fine. To control air volume, I use a three way valve (one inlet, two outlet) and simply bleed off excess air to the room air.

does not have an air filter as it is primarily designed to dehumidify air, which it does well. the amount of air released is less than what is taken in due to moisture removal. suggest you consider a separate air cleaner.

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.

There are several great short videos on youtube on starting and maintaining this filter.....I have followed their advice and have never had air issues....takes me about 10 minutes to tear down, clean and restart the filter

I think so. One side is black (the side shown in the photo) and turns grayish whitish from dust, etc. as it filters the air that passes through it, as long as you insert the filter in the appropriate direction.
