An important ONI filter, in 5 minutes.

[pettv]

been playing for 400 hours never seen this before, thank you for making a video and sharing it

Tony: yeah everyone knows about this. not ground breaking.
me at 800 hours of gameplay: *explodes*

First time I saw the mechanical filter was on the forum quite a while ago. It changed a lot of stuff. I use them in my electrolyzer rooms all the time. One oxygen filter on each vent and another hydrogen filter with a relief at the end for whatever backs up. One of the best game mechanic reliant designs.

An explanatory video of 5 minutes of ONI?😲
That deserves a LIKE!
👍

You are the first that explains this the right way, I spend the whole morning correcting their explanation, yours is perfect

[altaem]

Fantastic explanation. I've been using these filters for ages, but always had to check a reference to copy. I now feel I understand enough to easily build from scratch.

[Shammikaze]

I've wanted a tutorial on this for a very long time. Thank you!!

BRUH THIS IS BRUTALLY-IMPORTANT THANK YOU

To avoid the 100% 1000 seconds pipe of oxygen, won't it work if you use 2x separate valves system, gobbling up the reservor.
It's a bit of a stretch but the gas filter 100% uses no power.

This is clever. I wouldn't say this is an exploit though. It's working logically because of the rules of the game physics. If this is an exploit, then maintaining vacuum with a liquid lock, regulating heat transfer with open/closed airlock doors, or creating an endlessly circulating coolant loop with pipes are too, because none of these make sense outside of the game's physics. And so is 80% of the other builds you can make.

This is amazing!
also, if there's too much O2 for it to handle, just filter the CO2 instead, it works wonders
I'm already using this to filter the few H2 that manage to sneak on my O2 line out, it's a most amazing energy-free failsafe

I used this filter a while ago, but stopped, as it always buggered out when i reloaded the game. The filters would get a another element in it and would need to be reset. It's a while ago though and I've learned a lot since then.

...that's voodoo. i'm going to be integrating that into a bunch of systems.

[mr.derpyface]

My base has chlorine problems, vaccuming it is power intensive, and I started really far from space. This may be a lifesaver.

[Im-mvbf]

could just add a purge vent of sorts down the line that vents to where ever

[henriknielsen]

This is a good idea. Never thought of it. Thanks!

[HateBear-real]

This is very smart, but I'm not sure if I want to use it because it seems exploit-y.

[stanhogenelst]

You could avoid the overflow of the input by putting a gas valve on that pipe and setting it to 900g/'s.

You will have 10% less throughput but no over flow incase it is really important for it not to happen.

[itllBuffGaming]

Have close to a thousand hours in the game and never knew this... huh... 😂. I use sensors and valve shut offs to filter stuff. Cheaper power than actual filters but not as cheap as this!

[GeneralBlorp]

But how does one prime the primer? My guess is that you've used a powered filter at least once already, and another valve, offscreen to support this apparatus. I mean that's fine but you've violated the purpose of avoiding the use of powered filtration in the first place.
