I've been building and installing Corsi-Rosenthal boxes since the southern California wildfires were really bad a few weeks back and they've made a huge difference in my indoor air quality. Really highly recommend, should have done this years ago

We cant get panel filters in AoNZ, or I would have been making them and passing them out to schools and such. Our climate was never one that we had to have Central heating for the majority of the country, so we went straight into heat pumps.
Can you get filters shipped from the USA? This company sells them in bulk for reasonable prices and they're very good, but I don't know what our export situation is any more :(
shipping costs are prohibitive and FX is not being kind to our dollar right now .. I can get a 10 pack of HEPA filters from Bezos for fairly cheap, but shipping is 3x the price and the US$-NZ$ is at a historic level to begin with.
Don't get me wrong.. if one of AoNZ's billionaires want to kick in for a few 40' containers full of proper HEPA panel filters, I'll happily convert my shed into a production line and pump out 100 a day, but, billionaires.. yanno?
I wish you the absolute best of luck in that!! I was too but it got brought into the house last month and I ended up catching it for the first time. The silver lining is I didn't pass it to anybody because I'm always masking, but I would have loved to have just not caught it. It's real bad
you're not going to believe this, we dont have an IKEA here either
Even if we did, little chance of them importing any, as our infrastructure doesnt use them except for C/R boxes, and our present govt is led by antivax howlers
You can even make a filter with a single filter. There's even a link to test data. 1 vs. 4 filters seems to be mainly a trade-off between cost and time before needing new filter(s).
Thank you so much. I just ordered some. Does anybody have a lead on what the best fan would be to put on top of these? I’m replacing two air purifiers that I bought for the California fires that I’ve had since 2018 with these.
I got a 9" box fan (Black & Decker brand, but there are plenty of others) and multiple PC fans of various brands and they all seem to work just great for my needs
Ohhhhhhh thank you for this though!! I'm making these boxes for everybody I care about and it's slow going because I have to order piecemeal and wait for them to arrive (media money doesn't lend itself to a lot of large purchases lol)
Thank you so much!! I'm going to order some today. I have a whole pile of fans and filters here I'm putting together into different configurations for people haha
but you can do whatever you want.
I wanted to do squares.
three are lots of designs out now, but when we made ours years ago we wanted to go as simple as possible
Okay excellent! I'm going to try that with one of my micro CR boxes (6"x6") and see if it makes a perceptible difference in here. They seem really useful if so
Am a huge proponent of air purifiers & have owned several Austin Air heavy duty ones since buying for LA home over 15 years ago. We needed them again in NY during the Canadian wildfires. Now in Paris I have another one plus a Coway. Between the climate crisis & pandemics, clean air so crucial. Alas.
Indoor air quality is another one of those access tools that people don't understand will help them even if they don't care about COVID. It's great for ppl with allergies, dealing with bad outdoor air, just...lots of things. It was what I wished got more funding in the Biden days.
There are legit liability reasons for that - the same reason cons can't just let people bring C-R boxes in - but it is annoying and there should be a workaround.
Can you break this down for me a bit? (Sorry) How are there liability issues for air filters? I'm not well versed in this topic and it just seems like senseless cruelty without the context I apparently need
So, there's the usual if you have air filters and ppl get COVID, they try to claim it's your fault, but things like rules around fire hazards, noise, power safety, trips and falls according to friend who dealt with this for a con.
I have heard stories like this from all over and I swear to fuck if I ever get a chance to slap the everfucking shit out of someone responsible for making that sort of decision, I'm taking it
Shocking that everyone isn't like "man, the ROI on these bad boys is outstanding!" I think masks are useful tools with genuine drawbacks (like GLP antagonists) but I can't see any reason everyone doesn't want indoor air filters, they're win-win!
I have air cleaners running quietly in every room. They make a huge difference. Until this decade I had no idea how unventilated and poor AQ regular homes / apartments are
I was so desperate during the first of the big annual Bay Area fires a few years ago that this was the only fan I could find in any store. Actually worked a charm and is dual directional. (and left two gross circles of black, but better in the filters than my lungs)
I love mine! Have four from Clean Air Kits (the quiet computer fan thing is a big deal in our house). Got them for both Covid and fire season and they are awesome.
I'm bringing them up again because I swapped out some cheaper filters for better ones today and ewwww, I don't know a better argument for using air purifiers at the moment
CR filters changed my life so much during 2020/Orange Sky Day, I couldn't go back to unfiltered air. I bought a few Coway filters that I've use 24/7.l since.
You can also buy standalone carbon filters, literally bought mine at a marijuana grow shop. For mine I just have the drum on the floor and the fan on top pulling in through the drum and out the top, found a picture on reddit where someone also mounted a HEPA filter to the fan exhaust.
*A grower recommended these to me for removing weed smells from my strictly no-smoking apartment.
I taped one to the back of a box fan, very rudimentary... and damned if if didn't take all the weed smell out of the air. And litter box odors! And, forest fire smoke.
I got on this kick like two days too late to mitigate covid exposure in my home, but it's definitely making my recovery a lot more comfortable, I feel it when I leave the house. I haven't officially had it in weeks but that lingering cough and fatigue is a real bitch
I have fortunately evaded Covid so far, but I've had pneumonia a couple times, antibiotics kicked down the disease but the painful cough stuck around for a month or two and it gets old really fast.
(I've gotten both pneumonia vaccines by now.)
I got a couple of air filters a few years ago when the wildfires were REAL bad in the PNW, but I've noticed that just running them all the time also makes my house less stinky, and helps with my alergies. No reason not to.
Yes the desktop-sized minis are great, but what I really liked was just slapping a filter on the intake side of a box fan -- that worked great here in upstate NY when the Canadian wildfire smoke reached us.

pbtech has panel filters too
I'm still C-Zero and intend to stay that way.

I've built a few for around the house.
Killed two 20" box fans so far (one was 20 years old and the other was...unbalanced).
I've built a couple of smaller ones using 120mm USB powered fans.
For a real good time, get your hands on a particulate meter to quantify how well they work.

Tried to beat the prices on the filters you posted. It took a few minutes of searching and requires a bulk-ish purchase. https://unitedfilter.com/en-us/products/10-x-10-x-2-merv-13?srsltid=AfmBOoqnhVmtbkZHIF5LEyAidAMsdnCdDuqdX5fuOSNaxCKi00zN1I2D

(I have also seen some that were 20" x 20" that might be better suited for this use.)
