I don't know if this is already known or not, but gas and liquid filters can now be created in a 20W version by using two Gas Shutoffs, a NOT Gate, and a Gas/Liquid Pipe Element Sensor.

Very nice - how accurate is it? Like does it ever let a packet slip ?

It doesn't even need to be that complicated.  You only need one gas shutoff and a gas type sensor.  And it works like a charm.  The advantage of an air filter is you can get them going rather early in the game.  The advantage of this method is power efficiency.

I've never had a packet slip.  The sensor turns on the valve for carbon dioxide.  Otherwise, the packet continues along the pipe.

Could you explain the NOT gate here?  I think I kinda understand what is going on, but the logic gate stuff still kinda confuses me a bit.  I feel like enrolling in at least a basic programming class would do me some good.  xD

so its basically either one way or the other, the not gate ensures that its always one and not the other, it would be me space convenient to lay it behind the ladder to the left of the setup and just wire it direct but this shows it more obviously

This, in particular, is for natural gas.
If the gas in the pipe is natural gas, it will go to the right.

If the gas is NOT natural gas, then it will go upwards.

Should work for liquid pipes as well.

Thank you for taking the time to explain that. :)

@Kroning regarding your second screenshot, what's up with that T junction?  Are you sure the O2 is slipping past the element sensor shut off and not incoming from the other pipe?

I am sure.

Nothing wrong with T-junction. Gas flows from bottim. Right side was build first, so now it's already overpressured. Upper side new, so need more gas and pipe is empty.

When I came home today, I will make some tests with 2 gases. Maybe we have some bug here, or it's intended.

(or anyone else can do it ofcourse)

I think that was mentioned above as being relevant.  You used the more compact design from KittenIsAGeek, that is able to slip packets when the pipe backs up.  Koningkrush's design doesn't have that weakness, at the cost of requiring more space. to be built.

Nope. Never used compact design.

I use a similar set up (same as KittenIsAGeek) but only with one Sensor and one Gaz shutoff. The problem is when you have a small electricity fail the wrong gaz goes in the wrong direction as the "filter" is off.

I'll try your version.

Edit : I tried it, it's great thanks.

I haven't had a power failure since smart batteries, but I see how that could be an issue.   I suppose I could put a mechanical filter on the filtered gas side with a feedback to catch stray gasses for something that is extremely critical. Hmm.  

I cant get it working  i don't understand why ?? !

I set the filter on hydrogen : if it's hydrogen, it must come to the left. Otherwise, with the NOR gate, it will go to the right

I want to use this method to save power even if in this save i've no power shortage issue.(batteries almost always full)

Please somebody help

Here's my setting 

 

?interpolation=lanczos-none&output-forma

You can see the hydrogene coming to the right, or left , it is totally random ......

The automation view :

I hope it is a silly mistake not a bug.

ok i figured it out. the input of the gaz shut off need to be the intersection for the design to work.

I hope it will help others

There are drawbacks to this design.

  1. It fails if the pipes are clogged.
  2. It fails if power runs out.

It must also be designed specifically this way:

Here's a save file with my oxygen system: OxygenSystem.sav

You can simulate power outage by turning the power switch off. And remove the gas vents to simulate clogged pipes.
