BIQU Panda Lungs Filters Air Inside the Bambu Lab Print Chamber

BIQU has started shipping the Panda Lungs, a purpose-built air filter designed specifically for Bambu Lab 3D printers. The $99.99 device clamps directly into the print chamber and pulls air through a three-stage filtration stack aimed at ultrafine particles, volatile organic compounds, and odors.

The filter arrangement starts with a particulate pre-filter for dust and larger debris. A HEPA stage handles particles down to sub-micron sizes, and an activated carbon layer absorbs VOCs and smells. A small front display reports TVOC concentration, temperature, and humidity in real time, so you can see exactly what the printer is putting into the air.

The housing is made from ASA plastic rated up to 100 degrees Celsius, which means it can survive inside an enclosed Bambu Lab chamber without warping. ABS and other high-temperature filaments release more particles and gases than PLA or PETG, so the Panda Lungs is aimed at users who run materials that would otherwise fill a room with fumes.

Bambu Lab printers already include basic air filtration, but the stock setup is designed more for odor control than particle capture. The Panda Lungs targets ultrafine particles specifically, which are small enough to reach deep into lung tissue and have become a bigger concern as more users print in home offices and bedrooms.

At $99.99, the Panda Lungs is not a cheap add-on, but it is cheaper than buying a separate air purifier for the same job. The filter is also compact enough to stay inside the printer enclosure without eating into build volume or cluttering the top of the machine.

This is a narrow, sensible product. There is no app, no subscription, and no claim that it turns a Bambu Lab into something it is not. It just catches the stuff the printer already puts into the air.
