Or neutral pressure where the room is sealed and the filter simply circulates air, but that’s pretty impossible to do especially in any home set up so positive pressure makes and really simple.

Do I really have to spell all this out for you. Negitive air pressure keeps the outside air outside..... the point of a "CLEAN ROOM"

Positive pressure....come on now!!!! so your blowing air from the outside in. That makes no sense at all clearly defeating the purpose of a clean room.

I think you have your terms backwards. If there is a negative pressure in the room that means the higher air pressure outside will find a way in until it reaches equilibrium.
Correct, you filter your air as it comes in. The positive pressure in the room forces out already filtered air and keeps unfiltered air from coming in from a pressure imbalance (negative pressure or a draft[still negative pressure])
In your example, if you’re sucking air out of your clean room to create a negative pressure where is the fresh air coming from?

No your wrong I'm sorry but you are. You have your terms backwards. Negitive air pressure keeps your room clean, even when you open the door to get in contaminants will find they're way in. The reason for negitive air presure!! It seals the room from the outside and sucks contaminates out
Here is the point...you can sterilize anything and everything. Why the fuck not. Who cares. Brew up in space if you want.
However...how much will it matter if we are running everything through a 22 micron sterile filter at the final stage? Not one bit, or an amount so negligible that lead to gold has higher odds.
This does not mean, be a dirty fuck and brew in a bathtub on top of a landfill downwind from a slaughter house. This means that if all reasonable steps are followed...you will have a practical absolute certainty of sterility. Want to go above and beyond, you won't hurt anything but odds of further helping are virtually nil.

So if your have negative pressure in the room, how do you filter the air coming in through cracks and crevices?

Seriously!! Google negitive air system and air refresh rates. Your not worth my energy right now but this squat machine is!!!

Please make sure to read the whole thing and the reasons of suction of bottom to top and from top to the bottom because it makes a huge difference especially in the way the air moves

From your own link:
“Negative air pressure is used in cleanrooms where the goal is to keep any possible contamination from escaping the cleanroom.
Positive pressure cleanrooms are used primarily for industries where the cleanroom functions to keep the product clean and safe from particulates”
I’m not worried about AAS dust getting out and contaminating the house or “lab.” I am however concerned about stuff from the house or whatever a UGL brews in getting into my brew. Therefore, again, according to YOUR link we want positive pressure to keep contaminates and particulates from getting into the clean room. Why would I want to trap contaminates inside my brew space with a negative pressure like your article states?
Bro @mp46 is right on this one. With a negative pressure room you’re sucking into the room from the outside through a filtration system. Any unsealed crack or crevice is going to allow unfiltered air into the clean room through the unsealed cracks and crevices. If you open the door with negative pressure in your clean room, unfiltered air will rush into your clean room through the open door.
However in a positive pressure system the filtered air is pushed into the clean room through the filters. Any unsealed cracks or crevices will still leak but it will be clean, filtered air from inside of the clean room escaping out of the openings. Even if you open the door you will have clean, filtered air blowing out of the open door not allowing contaminated outside air to enter the clean room

From my own link that you left out
"Negative air pressure cleanrooms are used in industries that manufacture pharmaceutical products, do biochemical testing, and also in hospitals to quarantine seriously contagious patients. Any air that flows out of the room has to first flow out of a filter, ensuring that no contaminants can escape."
Case closed I'm done with this thread

You can't be serious right now?! Read what you quoted again.

Read what you just quoted bro. Used to manufacture pharmaceutical products, that’s not AAS. That mean products which you don’t want cross contaminating other assembly lines because it’ll kill someone.
Used in biochemical testing, again stuff you don’t want being cross-contaminated and can really fuck up a facility if it gets out.
Used in hospitals to quart one seriously contagious patients (I’ve actually been a patient here) but yet again we’re talking about keeping contaminating in. Why would you want to compare keeping contagious pathogens locked into a sealed room to brewing? Are you trying to lock the bacteria and shit in your brew house while you brew and bring in more shit when you have a leak or open a door? Or are you trying to filter the air coming in and keep all if the bad shit out of your brew room?
Again, keep pathogens locked in a room like your example/article and invite more things in? Or filter everything inside and keep everything else out?

HEY - CASE CLOSED!
Famous last words of someone who refuses to admit they’re wrong.
He’s still quoting portions of his link that refers to not letting any contaminants out of the room. He refuses to realize that a clean room for brewing needs to keep the contaminants that could get into the gear outside of the room. Not keep the gear from getting out of the clean room to the outside air.

I think he read pharmaceutical and assumes that’s what applies to us. I look at the hospital and think I don’t want that shit stuck in my room with me, but whatever.
How many ugl actually have any form of this stuff anyway?

Lol, 1 or 2
He is confusing the manufacturing of basic medication with pharma research where you have some nasty shit you don't want escaping or flooding the general air systems of a building. In certain areas the "sterile air" (relatively) is OUTSIDE the room.
Key is high pressure flows to low pressure in all things like gas and liquids...or weather on a grand scale. If you create a low pressure area, it is pulling in from any available source to get to equilibrium.
