It comes with a total of 3 1st stage filters. Does not have a way of connecting it to the printer. Only has a single analog dial. The grey square around the filters is just a corrugated cardboard spacer to fill in the gap from the filters being undersized for the enclosure. You could probably make your own with mostly printed parts and the filters from the bambu store plus an inline ducted fan for 1/3 of the cost. And it wouldnt need the cardboard spacer. Theres no machine integration whatsoever.
The cardboard spacer has handles, but when I pulled up on them, the cardboard ripped super easily. As you can see in pic #2
That is quite disappointing indeedâŚ
And those filters look suspiciously like those used in air purifiers we use at work.
Only that for them we have things they actually fit in without a throw away flimsy spacer.
Bambu gone cheap again, rather than supplying matching filters they add cardboard ROFL
Sadly they still charge good money for this âinventionââŚ
When I was still soldering like a mad man I had to build a suitable filter for those stinky fumes.
100mm PVC pipe from the hardware store, together with crew caps.
First stage was a few balls of stainless steel wool (for cleaning pots).
I left a gap between the two fillings of around 10cm and connected the steel wool to a high voltage DC source.
Like that the steelwool collects an awful lot of bad stuff and is easy to clean on warm water with a bit of sodium hydroxide sprinkled in.
Second stage was just a printed round screen with a fine infill only mesh either side and activated carbon granules between them.
In order to keep remaining bad particles of larger size out I later added a simple paper filter in the first screen.
If you want to re-purpose the spend filters from the box >
Check the design first.
Some use the foam tape to get the lower box part and the top, overlapping rim together - a pain to get the tape off but quite possible.
The other system I encountered is welded along a corner, for them it works best to carefully cut through the corner using a VERY sharp and thin blade.
Try to keep the plastic screens intact and once the paper screens wear out or get too filthy replace them with filter sheets used for filtering waste cooking oil, they are quite cheap and work well.
No need for hepa filter inserts unless you use a laser and produce a lot of smoke.
For the activated carbon aquarium shops are an option but it is way cheaper to order some activate carbon âcushionsâ from China.
Literally just thin fabric bags looking like a small pillow and filled activate carbon sourced from Bambu - the plantâŚ
I do recommend washing the carbon with distilled water first to get rid of the fine dust but thatâs optional and just serves dust prevention.
I keep refurbishing the filter for the air purifier in the room with my laser like this for about 3 years nowâŚ
Costs me about 5 bucks compared to the over 60 for a genuine filter to put inâŚ
HEPA filtration is highly beneficial when printing with carbon fiber materials, as these can and will release tiny, potentially hazardous fibers into the air and chamber. In my opinion, a HEPA filter is essential for this type of printing. Of course, itâs up to each person to decide what they want for their own setupâwhether they want to keep that stuff out of the air or not is a personal choice!
Nah. Its just a cheap cardboard square surrounding the other filters. the air doesnt pass through the cardboard. Its basically packing material used as a spacer. Its thin folded cardboard. Maybe not everybody is seeing what im talking about.
The fan is in the bottom. not the side
The cardboard surround isnt shown in this pic. The h13 filter slides into it.
To understand what youâre describing, I unpacked my spare filters (I havenât received my unit yet). The component you refer to as âcardboardâ appears to be the final filter in the chain. Do you mean there is an additional enclosure around these filters before they are installed in the unit?
Yes. A thin cardboard surround is what the 3 other filters slide into. Its grey. In pic 1 below, zoom in on the pull handle and youll see the tear in the cardboard. The whole unit should have been under $300
The final filter and its cardboard housing constitute a single unit. Do you think the housing should be made from a different material? I agree that the pull tabsâwhich are designed to extract the filter and its housingâcould be more durable, but theyâre integrated into the same assembly and cannot be separated. If you still regard the cardboard as merely filler, rest assured it will be supplied with the filter assembly combo.
Are you thinking the cardboard surround is part of the bottom filter? Do we think it came that way from the supplier? Or glued on afterwards as a cheap spacer? The surround does no filtering. Its literally super thin cardboard folded into this shape. I gave up on getting the very bottom filter out after seeing that the cardboard ripped like wet paper, so im not sure if they are even glued. There is a pic pointing at the thin charcoal filer. People may be confusing that arrow as pointing at the cardboard surround instead of the internal filter that its pointing at
The link you posted no longer works
Ill probably ditch the cardboard and print something air tight
Does it matter whether that section of the filter arrives pre-assembled? When the filter has reached the end of its service life, you can always fashion a DIY replacement element if needed.
For reference, hereâs the complete filter combo, with the two active filters mounted on top of the âfillerâ filter:
Only matters because its a sloppy way of doing it. Just the filters are $165. Even thicker cardboard would be an improvement. My whole point was that its not worth the $ and people should think about building one with an inline fan and filter cartridge.
Just trying to help customers. Not company. I spent the money and now others know without having to.
Itâs certainly expensive, but the two individual filters arenât particularly costlyâitâs only the combo that carries a premium price. That said, I agree there are several aspects of the unit that could be improved.
Sorry i wasnt more clear. By no machine integration, I meant theres no way of controlling it via the machine. Only has a wall plug and an analog dial. I did receive the hoses.
Thatâs typically how smoke purifier replacement filter packs are made. All together in a cardboard housing. This way itâs just a drop in replacement instead of digging separate filters out. I do agree though, the price is a bit outrageous. Iâd definitely be making my own filter packs.
I like this setup. Now that im looking around, looks like alot of really cheap brands use the filter surround, but a more robust material than packing cardboard. Good brands just have filters that fit the housing.
