What have you done to filter out the toxic particles generated from 3D Printer?

Thanks for your expert opinion. Although the 3D printer dealer suggested making a hole at the back of the case and put a fan inside, the manufacturer mentioned that doing so will void the warranty and as you mentioned, it could affect the print quality.

As I live in a condo, making a hole in the window is also out of option. The most I can do is to just put the opening of the aluminum duct to face the window. For a large printer such as the Raise 3D+, is there another way? Perhaps have some kind of filter put inside the machine perhaps below the filament area or on the big plastic cover on top?

How effective it is if I get a large bag of Carbon filter and use it to cover the entire printer? Not sure how effective such "passive?" method is. Note that there are four fans in this printer. Two at the extruders, one at the bottom of the machine and one at the side or back. If the Carbon filter bag is long enough to touch the floor, not sure if it would affect the circulation and cause damage to the printer. However, if I cover the printer up to the top of the casters, those nano particles could move around the apartment.

How about a window vented AC Duct

Remember you have a 3D Printer 3D Print your own, wanted to give you an Ideal.

I went with a thru the wall with a bathroom vent without a filter, was thinking about using 65mm gas mask filters and recirculating the air.
I however live is a very dusty prairie environment and finally decided on the aforementioned Bathroom fan vent.

Placed both 3D Printers inside a negative air pressure case. Negative air pressure environmental chambers can allow the chamber to be partially open, allowing for outside air to be drawn in and not allow the inside air to escape thru the opening. We only need a little negative air so don't run the fan full speed only enough to move air outside. I Use this manner you can vent the chamber air to the outside thru a window vent as shown above. If you want you could vent this thru a hepa filter of any vacuum cleaner. I even thought a filtering thru a 65mm gas mask filter back into the chamber.
