Helps reduce noticeable odor and airborne byproducts by adding 3-in-1 filtration to your P2S exhaust path. Filtration media: HEPA + molecular sieve + activated carbon to target particles + odor/VOC adsorption
Regenerable Adsorption Core
Regenerable molecular sieve: dry at ≤60°C (140°F) for 4–6 hours to restore part of adsorption performance. Replace after 3–4 regeneration cycles (or when performance declines)

This P2S exhaust filter is a reusable 3-in-1 upgrade for Bambu Lab P2S External Exhaust Fan Kit, combining HEPA, molecular sieve, and activated carbon to help capture fine particles while adsorbing odor/VOCs and moisture during printing. It installs as a tool-free drop-in replacement. For best performance, you can regenerate the molecular sieve at ≤60°C (140°F) for 4–6 hours, and replace the filter after 3–4 cycles when adsorption noticeably declines.

P2S HEPA Exhaust Filter Overview
Better Than Original P2S Exhaust Filters
Basic filters are often single-layer and must be fully replaced frequently, which increases long-term cost.This upgrade combines HEPA + molecular sieve + activated carbon so you can target fine particles and adsorb odor/VOCs and moisture in one cartridge.The molecular sieve core supports low-temperature regeneration, helping extend usable life vs. one-time-only media

Requirements & Installation Notes
• This filter is designed for the Bambu Lab P2S External Exhaust Fan Kit. Before ordering, confirm that the P2S configuration you are purchasing includes the External Exhaust Fan Kit, or that you have already purchased the kit separately.
• For the official fan-kit installation, update P2S firmware to 01.01.01.00 or later, Bambu Studio to V2.4.1.80 or later, and Bambu Handy to V3.11.0 or later.
• Choose the dedicated updated rear panel or the original rear panel with the supplied adapter, following the official installation guide.
• A standalone P2S without AMS requires an additional Filament Buffer for the External Exhaust Fan Kit.
• If installing the fan kit from scratch, prepare the required parts and tools, including H2.0 and H1.5 screwdrivers; Bambu Lab recommends PETG, ABS, or PC for the required printed parts.
• Install the filter into the external exhaust fan housing and follow the official guide for filter-corner sealing, fan-kit assembly, cable connection, and optional exhaust-pipe installation.

Frequently Asked Questions About P2S HEPA Exhaust Filter
Will the P2S exhaust filter eliminate all fumes?
No filtration system can guarantee complete removal in every setup. Performance depends on the filament or material, print temperature, enclosure sealing, exhaust routing, filter condition, and room ventilation.
What is the actual effect of low-temperature regeneration?
It only removes free water on the surface and in the pores, but cannot remove deeply bound water inside the molecular sieve.
Its adsorption capacity is generally restored to about 70%–80% of the original level.
Suitable for: daily light use, 3D printing filament moisture protection, short-term repeated use.
Does the Bambu Lab P2S need additional ventilation?
If exhaust is routed outdoors, an additional filter may not be necessary. If exhaust is released into the room, filtration should be paired with appropriate ventilation, especially when printing higher-emission materials such as ABS, ASA, or Nylon.
Can the P2S exhaust filter be washed or regenerated?
The molecular sieve can be regenerated at ≤60°C (140°F) for 4–6 hours in a dry, well-ventilated area. Do not wash the complete filter unless the product instructions specifically allow it. Replace the filter after 3–4 regeneration cycles or when adsorption performance declines.

Support FAQ
What Should I Buy from Call3D?
Call3D is particularly valuable when you are looking for:
- Carefully selected third-party accessories, mods, and upgrades for Bambu Lab printers;

If customers need help before ordering or encounter a problem afterward, they can contact the same team that selected and documented the product.

Found this shop on Reddit, chatted with a real person about the P2S filter I needed. Asked if they could ship to SG, they checked and made it happen! Super happy because this filter is basically impossible to find locally and always out of stock everywhere else. Fast, friendly, and solved my problem perfectly. Will buy again!

When EP invited me to Shenzhen back in 2019, I was absolutely blown away by the hardware innovation coming out of China. Just one year later, Bambu Lab burst onto the scene—and their solutions have grown right alongside Bambu, evolving from the very beginning to where they are today.

Bought a ventilation system but changed my mind last minute. I thought returns would be a huge hassle, but they told me there’s a return warehouse in Houston only about a 10-minute drive from where I live in Missouri City. Drove over and returned it super easily. Super convenient return process, great experience overall!

Just received it today. The filter looks well made and matches the P2S setup, so I’m planning to install it later and see how it performs. Shipping was quick and everything arrived in good condition.
