What are people doing to manage 3D printing fumes?

Living in a warm part of the country, I've been pretty casual about the fume management approach. Most of the year it has been open the window, close the door and come back when it is done. I want to improve this so I can print a wider range of filaments and not cool the house down in the winter.
There is a bunch of information out there, here is a good overview example.

In my case I could vent the room (e.g. a bathroom fan in the ceiling), or build enclosure(s) and either vent them to the outside or filter (HEPA and possibly carbon). Here is an interesting discussion on HEPA effectiveness (note it is a filter vendor).

So, I'm interested what others are doing.

   I bought one of these.

(( the black one ))
    I built two side walls and a frame to support it, it stands 36-ish inches to the bottom of the hood. I vented it out through one of the glass blocks in the basement similar to how you'd vent your clothes dryer. I still have not added a set of doors to the front. It's great because the lights underneath actually add enough heat to combat any troublesome temperature changes. The resin I have been using has a strong clove-ish smell and I hate it. With the fan running top speed, it's actually very quiet. I leave the fan on for a few says after printing and the smell almost absent. I am sure there are more elegant solutions, but I got a deal on the hood and the rest was not really an issue. I did end up running some Romex and a box with four outlets on the wall near it. I will get it cleaned up a bit and post a few pics.

a much needed thread

and forget about VOCs, nanoplastics are major endocrine disruptors today
also transgenerational meaning they accumulate for real

my current recirculation filter is the airmanagerv2 on thingiverse slightly modified
to my fit a h13 electrolux filter available everywhere and this blower
https://m.pt.aliexpress.com/item/1005003092105754.html?

I'm not sure the blower kind fan is best for static pressure? i see most projects usings normal fans... anyway this serves a dual purpose on my enclosure in that it helps keeping the filament very dry(humidity 90%+ here year around)

but on the other hand it blows so much air and the vacuum through the filter is so weak in comparison that the exhaust robs the air flow of the filter

the electronics is redundant as I'm controlling it 100% through klipper now

you can attach a flexible pvc vent tube to outside creating negative pressure but then you'll only have one pass through the filter which is still good for 95-98% cleaning

or use a h12 filter which has bigger pores or a hepa sheet not folded like these made for aspirators

or maybe vent outside and then back inside with a second filter at the reentry to slow the airflow

 just brainstorming

Baco:
I printed another version in one piece
attached in this post if you want to remix it
here's also an easy way to fit your hepa/vacuum/fan devices to other projects


get a diagram with measurements like this one from the Ali listing


convert it to svg:

open it on tinkercad

Baco:
i was looking into the venturi effect for creating a vacuum on chemical distillations and thought it might be cool applying it to a filter
