Having your windows always open is great and all but especially during the winter it's not really possible unless I'm sleeping or outside so is there an alternative? Do these air purifiers work or perhaps there's some other technology that could be useful for my problem?
what
why isn't it possible
Here's a starting point for you to explore.
That's great but that's beyond my skills and I definitely can't afford to destroy my windows like that.
It's a crude design but there are better ones out there. The video was meant as a starting point, not as a spoonfeeding.
I unironically refurbished some O2 concentrators that I bought from an old folks home near my house for that crisp feeling. Air feels like when I lived in the mountains now.
why does it open to the outside
ventilation in modern hvac systems is a good topic to look into. most old homes just recirculate air and don't supply fresh air to the home. Leakage or windows or appliances pulling air in and pushing it out is the only way to ventilate and it's not generally done in an organized fashion. Sometimes the hvac designer will open a return to the outdoors so it will pull a small percentage of fresh air into the system every time it cycles.. this is a decent idea if they aren't pulling the air from someplace disgusting like a moldy attic.
I worked in an older home built in an affluent metropolitan area in the 1950's of brick and block and slate. They had no HVAC but they did have a giant 3'x3' fan at the top of the main flight of steps on the top floor which could be turned on and would pull hot air out and allow each room to open windows to pull in fresh air. A simple and more effective method than we've managed to institute in modern mainstream homebuilding practices.
Really high end modern homes will have a device added on to the hvac system specifically to handle ventilation and they will extract energy from exhausted stale air to warm or cool fresh air. They call these device heat recovery ventilators and they add significantly to HVAC cost and require maintenance.
Frankly i really like the ingenuity of the big ass fan method but perhaps a bit more updated.
I took the cheap approach and installed bathroom extractors on the upper rooms, also got those flappy covers for the exhaust that close when they're turned off and they even look good, i chose the ones with a little lid and painted them to match the room they give them more of a decoration feel than just a hole with a fan
How loud are they? Noise levels have always been my main complaint about bathroom fans.
The manual mentioned 40db ("Like if a light rain were falling outside.")
On my case one room if furnished and its like faint radio static. The other one has just boxes and you can hear it but nothing annoying.
hey that's one way to do it. I hope you don't have radon.

I looked it up but it made no sense to me. I have no proble letting them stay open for even longer as I don't care about the temperature as long as they are not constantly open but I feel out of fresh air very quickly when I close the windows.
> but I feel out of fresh air very quickly when I close the windows.
Unless your in a tiny room or have a moisture problem, ventilating your entire house should last you a few hours at the very least

Thanks!
I have no idea why it happens either, my room is decently sized and I have no mold.
