Wathai 2 Pack 120mm PC Fan Dust Filter Cover Computer Mess

I bought this because I was making a fog chiller for Halloween. Needed this to mount a small fan onto a 4" to 2" PVC reducer inside the chiller to create a positive pressure atmosphere to keep pushing the fog out even after the fog machine stopped. I hot glued this to the PVC reducer and my fan just pops into this, now I can remove the fan in off season. Needless to say this worked perfect and fit my 120mm fan (which is water proof). This was the last piece I needed to complete my fog chiller. I didn't use the filter as all I needed was the plastic piece to mount the fan.

Easy Directions for assembly Easy to read all parts were there use it for smoking smoke works better than expensive alternatives

Fits nice on my fans.

Easy to install with included screws, little reduction in airflow, looks nice. Cover snaps on, is a real pain to remove for cleaning filter.

These filters/guards work great with the 120mm fans.

Great filters to minimize dust on my fan. Doesn't hinder air flow through fan.

If you are installing more than 1 together, like over a cooler radiator, the size of the covers may interfere with each other if you have fixed screw hole locations. In single installation applications they work ok.

I have been running for almost 3 years and they still are running 24hrs a day usually.

As described but way overpriced for what it is. Note the item is not built for disassembly (e.g. for cleaning) - it firmly clips together and stays that way - if you pried it open the tiny clips would soon break.
