Thread 2947094

I'm finding that I struggle a lot with sleeping and doing certain things that necessarily lead me to believe that my bedroom has bad air flow. My bedroom is in the basement of my house, has no windows, and exactly one doorway in the opposite corner from my bed. We do have a vent system but it's old and doesn't have A/C, only heating, which we never use, so it's basically a static non-variable.

I always keep a fan on blowing in air from the door at night, but of course that doesn't help. What can I do to fix this problem? I need to be able to breathe better.

That sucks and spunds illegal
Anyway get a dehumidfyer

>>2947094 (OP)
Can you just add a window? This seems like a relatively easy fix.

You could put a high pressure gradient fan on the vent to pull air in, assuming there are no solid elements blocking air flow there. Alternatively get a hole core drilled in the exterior wall and put in a ventilation pipe.

Use a duct to insert blow air to the far end of the room.

test for radon

This is actually really important. And coincidentally, the fix for radon is the same as the fix for stale air: pumping new air in and old air out.

I think you just want a simple duct for air circulation.

So a square hole at the top of the wall, which let's hot air escape, and a low hole or pipe at the bottom of the wall which let's cold air in.

Humidity could be a factor, in that case you just put a little 12v box fan and a dehumidifier in the duct. Damp air is less comfortable generally.

If you can't install ducts by sawing holes for pipes, well then you'd get a commercial style duct, a silver tin foil tube that hangs from the ceiling and dies exactly the same thing

For first, check to see your vent system is set up correctly. They should work passively. They should have blocks/covers and you need to take them on and put them off in the right combination to get the air to flow.

Also test CO2, shouldn't be >1000ppm for long periods

>it's old and doesn't have A/C, only heating, which we never use
buy a modern thermostat and use fan only mode

to where exactly?
>and a low hole or pipe at the bottom of the wall which let's cold air in.
from where exactly?

Open the door?

Measure the CO2 anons, especially where you sleep or spend the most time. Was into this long before covid bs. So many people live in awful AQ environments without realising. High CO2 env turns you retarded. Few minutes of fresh air flow a day can be enough

I temporarily rented a room like that. I stuck a cheap Walmart fan on top of the vent to suck air out of my room and i would leave my door open. It helped alot because the previous tenant had black mold and would sleep in that. I never had black mold or any kind of moisture issues because of the constant air flow provided by the cheap fan.

Get a dehumidifier and a good fan. I had to deal with this when I first moved into the basement as the air was stagnant and heavy and just ugly. Dehumidifier and fan have made the basement bearable.

>>2947094 (OP)
A fan within the room circulate air within the room. To circulate air into the room you must blow air OUT in order to create a suction to draw air in from an opening in the opposite end of the room. If you have a small fan blowing out the crack at the bottom of the door that will create suction and draw air in from the vent system, or the crack at the top of the door, but if the only air is from the top of the door, once draw in, it will go out under your door instead of the rest of the room, unless you have another fan blowing air from across the room that can reach the fan blowing air out the room.

Not OP but this thread is relevant to my interests, so huh anyone knows if those cheap aliexpress monitors are decently accurate? I'm looking into first of all, making sure CO2 levels are within healthy levels. I'm interested in this one

Just as I was loading the tab on my browser to make sure it was the right url, I found this negative review

Unsurprising, I tend to stay away from chinkshit for health and/or critical applications, but money is tight as ever it is what it is. Can anyone recommend me a good and accurate 'air quality' monitor with the basics like CO, CO2 and what else? The cheapest, seemingly reliable one (made by an american company as a sort of 'libre' device, the kind that everyone can build on or check internals) was like $100, without shipping.

Replying to myself before pulling the trigger on this thing

More negative reviews. Eh fuck my poorfag life then! Everyone says the Ikea one is a good, solid choice but doesn't seem to track CO2 (what's used for stale air I believe)

The Ikea Vindriktning, at $16, seems to be out of production and its replacement is at least $60. Yeah I think putting a bunch of fans is going to be cheaper without ever measuring values accurately, not like you can do much about it can you? Another thing I noticed is the Ikea monitor measures up to PM2.5 only, which is kind of a moot point from a few research papers I've skimmed over saying that what truly hurts you is <PM1.0 because those go straight into your bloodstream or something.
