Moving into an apartment after three decades in houses, I'm learning how bad CO2 build-up can be, esp. since it pools from the floor up, and my futon bed is low. A C-R filter works great, but I'm considering a soda lime filter for the CO2. This might be particularly helpful around babies and day care, if there are no side-effects.
The Corsi-Rosenthal filter is easy to search on UA-cam, or even to imagine taping a 20x20 filter to a simple box fan. I have two and they work fairly well. The Corsi is a step up.
It would be also interesting to understand which role do sensors (CO2, PM2.5 etc..) play in this, especially if energy efficiency of the whole system is also a factor which need to be watched. What do you guys think?
As an ex HVAC tech A simple box fan motor will burn up due to restriction of the said filters. I recommend getting one from a store with a good warranty, because it will get hot and fail. Have you ever seen a box fan sold with a filter? Or seen filters made for box fans?
Hi Miles. I had similar concerns and initially watched my Corsi Rosenthal boxes like a hawk. It turns out that the four (or even five) filter cube design allows so much airflow that there really isn't much resistance on the fan motor at all. I have regularly run them in 8-hour intervals for six months without issue. Common sense stuff like not running them in an unoccupied space is still smart though. 👍 The only box fan/filter model I am aware of is the Lasko FF305 Air Flex 2-in-1. It uses a MERV 10 filter, and I wouldn't feel comfortable upping it to the recommended MERV 13.

Or we could stop listening to the advice given by people who are freaked out by life in general (like video above) for a virus that is mild in nature who do not kow what they are talking about Seriously you work for a "science magazine"..... and your duct tape filter box in a dorm room is not comparable to a hospital.
She’s soooooo scared of Covid and did soooooo many things to prevent it and still got it, but she wants you to know how wonderful and better than us she is. How does she work at a science magazine? Incredible.
It is not race so much as socioeconomic status. The most deleterious environmental industries are often located in poor areas because they lack the resources to contest placement.
Last 2 and half years I have spent mostly indoors due to the situation. I never fell sick, I never contracted COVID. Indoor air quality is anyway good considering you stay in a less polluted environment. So these videos are just money making schemes to make Dyson or other companies rich!
How about putting the link to those plans in the description

Here are directions for making your own DIY air filter - the CorsiRosenthal Box cleanaircrew.org/box-fan-filters/
I suggest you pin this comment
FYI, the DIY box is very loud
I set mine to medium or low after a while. As long as it works, eh?
If you do the PC fan model, the noise is less than many HEPA devices
Good to know! Thank you for sharing! Greetings from Canada!💯💯✅✅😃😃

If you are interested in CO2 monitoring, we have a new model that is small and compact: ua-cam.com/video/z59ve7T407M/v-deo.html
Pass gas outdoors.
🤣
Very neglected area in regards to public health

The answer is always to force people to do our bidding.

Bad air quality makes me sick, I guess “I must be freaked out by life in general”

What you said makes no sense
@@Josh-Parkhill ok
I was with you until you brought race into it.

Your own fault for being with her until that. This was clearly bullshit from the start.
Such a delicate flower. Please, no one remind him that there are people who are different. Steve is sensitive.

You figured it out. Will the fan industry ever grow tired of manipulating us with their insidious viral marketing?
@@olorin4317 Fan cools your body through surface evaporation. Dont know about viral marketing but fans are necessary.
Lmao
You really aren't very smart are you?
Move to Venus. If you're having problems on earth. And don't come back complaining that we didn't told you that you forgot carry your food.
Uh oh, I think it's happening. This dude clearly has insufficient oxygen going to his brain.
