I am once again feeling pretty good about having a personal air purifier in my office. Every few months it tells me to change the filter and the old filter is gross and grey.
I got the air purifier to help me feel more confident about seeing people in my office in person, what with COVID. It's also helped with Canadian wildfire smoke and whatever that weird smell was that came in through the building's air intake (I think the rubber roof was outgassing in the heat wave, it smelled dreadful).
(Blueair 411 for $80 in 2022, pretty much a glorified Corsi-Rosenthal box, a fan on top of a cylinder of air filter.) #airpurifier #backtotheoffice #minorhappy
I just went to turn my air purifier on in the bedroom (allergies and a lot of dust kicking around from all the DIY that has been impossible to keep on top off)... and realised that the little one like this that I currently have.
Is only good for a small room of about 8-10sq/m
My current bedroom is nearly 13sq/m, but it works well enough to stop the watery eyes and sniffles at night.
My new bedroom is nearly 20sq/m inc the bay window and that's after pinching about 2sq/m of it to enlarge the ensuite.
So I might be in need of a new one, a quieter one.
My current one I've seen about under various brand names, my is branded ADDIS, but I've seen them in B & Q (can't remember brand) and also on Amazon under the NETTA branding.
It was cheap, cost me about £20 in a sale, they're currently about £33. Filter packs are £12.99 and need cleaning every few weeks and replacing about once a year. But it's not the quietest and would need to be placed right across the room where it might not be effective in such a large space.
Does anyone have one that can cope with a largish room, isn't expensive and doesn't require a £30-40 filter change every 3-6 months and under no circumstances is 'smart' or needs 'wifi' or an 'app'... it just needs to filter the fucking air, not suck up all my personal info.
Recommendations?
Must have
HEPA filter (at least a 3 stage filter, pre-charcoal-hepa)
Night mode, very quiet (under 35Db)
Under £100

@magicfab This looks like a very interesting solution! Thanks
Based on my research, it seems possible to use an ESP32 and ESPHome to control the speed of the Noctua P14s Redux PWM with Home Assistant.
- Adjust the speed based on the level of air quality
- Reduce the fan during to 30 minutes after switching my room to sleep mode.
- Automation base on presence
This looks like a cool DIY project to do :-)
Spotted this cool Canadian-made air purifier: North Box Systems builds quiet, energy-efficient units using PC fans + MERV-13 filters. Think: Corsi-Rosenthal box, but sleeker. Great for wildfire smoke & allergens.

#Ottawa's air is thick from the #Manitoba #wildfires again.

En train d'expérimenter la fabrication de petits purificateurs pour l'atelier où je bricole à la maison (donc surtout seule, c'est plutôt pour les poussières)
Et j'ai fait ça :
-> un filtre d'aspirateur (MVAC012)
-> 4 pièces imprimées en 3d (qui font des quarts pour encercler la base du filtre
-> 2 ventilos empilés (que je vais changer pour des F12 parce que là c'est un peu nul)

Observation re hay fever: I moved into a smaller apartment in November, and I took the air purifier with me.
Now, inside my place, I rarely have any hay fever symptoms. So much so that I forget about it, and when I then go outside, it hits me quite hard.
Two learnings:
1. those things work really well! I think I hadn't noticed before bcs the old place was too big.
2. always take antihistamines with me

I changed my 6 month old air filter in my IKEA Förnuftig air purifier in my workshop yesterday as part of my big spring clean and as I was disassembling it (fortunately a very easy job!) I was wondering if it makes much of a difference.
Then I put the old filter next to the brand new one and decided that holy cow, yes, it does! 
I should get around to installing the bedroom one at home...
