MaxxFan Exhaust Filter

[mossemi]

A few years ago, topgun2 created a filter for his MaxxFan that I really liked, but the frame material he used was no longer available.  
Although this is my version below, it is similar to his.

So I kept it in the back of my mind and often looked at different materials to create my own.  I tried some vinyl channel that was used in shower glass installations, but it was too flexible.  My next version was metal channel that I am unsure of it’s purpose, it worked pretty well, but I kept cutting my hands on the mitered corners.  Then I found some plastic or PVC channel at Lowe’s while shopping for PVC lumber and it worked pretty well.

This is the frame material from Lowe’s.

 

I removed the round screen filter and stored it somewhere I might be able to find or maybe not.  I measured the fan frame and cut the channel to size.  Then I cut some sheet aluminum into triangles and glued up the frame using the triangles for corner supports.

Then the filter material was cut to size and inserted into the slot and then Velcro Command picture hanging strips were used to hold the filter frame to the MaxxFan frame.  This resulted in gaps between the frames which I filled with leftover filter material.

 

The result is a removable filter that can be washed and reused and the fan blades require less cleaning.

He recently saw my version and asked me to post it for you to see it and improve upon for your own needs.

Nice job - Mike!

If anyone cares to duplicate Mike's effort, be sure to note where he has placed the filter on the fan - inside of the "outside" plastic edges of the fan.  This is due to the size of the filter material which can be obtained from places like WalMart for about a dollar.  Further explanation of this can be obtained from Mike & Carol given that I installed their channel in the wrong place before trying to install the filter material 🤪.

p.s.  besides keeping the fan a bit cleaner, this filter material also provides a bit of "shade" from the light that comes through that fan.

It was a good effort though!! 🤣

I'm curious. Does the maxfann not have a removeable bottom screen, like our very old fantastic vent? 

Most of our dirt is from the outside, even though it's almost always used on exhaust.

Curious, as I've never had a maxxfan, other than the new bath vent. That inside screen is removeable for cleaning.  Not as easy as fantastic (two or three tiny screws on the maxx), but, it is removeable. 

Love the idea of the filter material darkening the interior space, though. Might do this on the fantastic,  just for the darkness

Yes, it has a removable screen.  Easy to remove and clean.

The stock MaxxFan screen is similar to a no-see-ums screen door.  It's really not a filter, it’s a screen.

That should help keep the fan blades cleaner. They're a pain to clean,  in ours. Thanks.
