Important Notice Before Purchase
Optimizing Your P2S Experience
To ensure a premium experience for our early adopters, the Updated Rear Panel is now available as a complimentary option. While newer P2S units include this panel pre-installed, both versions are fully compatible with the External Exhaust Fan Kit.
How to Choose: Please identify your panel version via the [Bambu Lab Wiki] before ordering:
1. If you have the Updated Rear Panel: You only need the External Exhaust Fan Kit.
2. If you have the Original Rear Panel:
-
Recommended: Add the Updated Rear Panel with External Exhaust Fan Kit for optimized exhaust efficiency.
-
Standard: The External Exhaust Fan Kit can also be installed directly onto your original rear panel if standard performance meets your needs.
Description
The External Exhaust Fan Kit transforms the P2S's standard internal circulation system into a powerful external venting solution. While the stock P2S uses an activated carbon filter for internal purification, this kit allows you to duct fumes directly outdoors or to a dedicated filtration system.
Once installed, the printer's firmware automatically recognizes the hardware, unlocking "Adaptive Air Flow" and a specialized "Purify Air After Printing" mode. This is especially critical for filaments like ABS, ASA, and PA, where clearing the chamber of residual gases before opening the door is essential for a safe workspace.
Overview:
-
The P2S Printer comes with a built-in recirculating air filtration system as standard, which relies on an internal activated carbon filter to purify the air inside the printing chamber. Designed specifically for users with strict exhaust requirements, the External Exhaust Fan Kit adds an active external exhaust function to the P2S after installation, delivering more efficient directional air extraction performance.
-
This kit achieves seamless integration with the printer. Once installed, the printer can automatically switch its operating mode based on the type of filament being used. Meanwhile, users can also manually adjust the operating mode via the printer’s touchscreen, Bambu Studio software, or Bambu Handy mobile app.
-
With the kit installed, the P2S gains an automatic post-print air purification feature. For engineering-grade filaments that require enclosed printing (such as ABS, PA, etc.), simply enable the "Purify Air After Printing" option in the printer’s settings menu. The P2S will then automatically activate the external exhaust mode upon print completion, thoroughly expelling any residual fumes from the chamber.
-
The External Exhaust Fan Kit supports expandable air filter cartridges, which are available for optional purchase according to users' needs.
-
If you own the P2S Printer without AMS, you will need to purchase an additional buffer accessory to use this exhaust fan kit.

Toddler approved
Size: 4T-5T, Unit Count: 99
Fits true to size and easy to pull up and down by my toddler. Very absorbent - perhaps a little too absorbent as it's taking my daughter forever to be potty trained and she's content in her soiled training pants... Great quality overall.

They prevent leaks, and fit great!
We have always used Huggies diapers for our babies and young toddlers because they were the only ones that never leaked or caused a rash. My second daughter was fully potty trained at 2.5 years old and never needed pull-ups. However, our third daughter, who also trained at 2.5 years old, digressed with her nighttime potty training due to instability - we moved twice within the first 6 weeks after she potty trained. So we had to get pull-ups for her to wear at night. Obviously since we loved Huggies diapers, we tried Huggies Pull-Ups, and again, they did not disappoint! They never leak, even on nights when she doesn't get up to go at all, and has lots of pee, and they have never caused a rash either, no matter how full. She's been using them for 1.5 years, at night, and we have never had any issues. They are dependable: decently comfortable to the child, do not cause rashes, fit properly with the ability to adjust at the thigh (if needed), and they prevent leaks! I highly recommend them!

Finally, a good night's sleep.
For almost a year, I've had sleep issues. No problem falling asleep, but I'd wake up 3 hours later and be up for the next 2-3 hours. I'd finally fall back asleep just a bit before the alarm and spend the rest of the day in a fog. It didn't matter whether I went to bed at 8:30 pm or 11pm - I was still up by 1:30-2 and awake for hours. It gradually got worse and I got desperate.
A friend recommended Melatonin and I resisted at first, having tried it after our daughter was born (almost 15 years ago). The tablets I took then had some odd side effects and I only took them for a few weeks before throwing the bottle away. Now, I think I have have been taking far too high of a dose, because these 3mg tablets work great.
Be careful when you take them! I'm awake and alert for about 20 minutes and then zone out totally - even in the middle of a conversation. After a couple of months, I've learned to just lay a tablet on my nightstand and take it when I'm ready to turn out the light. It works great: cured the problem of middle of the night sleeplessness. I still wake up sometimes at night, but have no trouble dropping back off to sleep. And when I wake up in the morning, I'm alert, energetic, and not already counting the hours until I can go back to bed to get a good night's sleep.
For me, this supplement would have been a good buy at twice the price - and my family agrees. I'm rested, cheerful, and so happy I gave it a try.
So far, no bad side effects. In fact, no side effects at all. I am taking it daily, but considering trying it on a more limited basis because of concerns about long-term effects. Considering, but haven't done it yet because I'm so enjoying a good night's sleep that I'm afraid to tinker with success!
Although I saw results the very first night I took this, I waited to write a review just in case it was a placebo effect at work. But it's been 11 weeks and I'm confident that this product is really effective for me.

Time release.. ONLY way to go
Used this brand before... when refill needed, came back for more. Time release is the best way to go as it works all night.
Not one big hit when you 1st go to sleep... A nice "hit"... to get you to sleep and then a slow release of the rest, to KEEP you asleep...
Don't think you'll be disappointed. I use sustained release with any vitamin/supplement I take (assuming the company makes it) .. including this. It's the best way to allow your body to utilize the product.
