Do air purifiers protect against COVID-19? What about

I researched air purifiers to protect against covid for a friend who has some special health issues. Thought I'd put up the basics here.
Air purifiers with HEPA filters really can filter out virus. The more air they process, the more they reduce virus concentration. Processing speed is measured in CFM, cubic feet per minute. You want one that will give you at least 6 air changes per hour (called ACH in the trade). So to figure out how powerful an air purifier you need, in order to get 6 air changes per hour, do this: (1) figure out cubic feet of area you want to keep safe. (2) Take 1/10 of that figure. (3) That number will be the number of CFM, cubic feet per minute, that your air purifier must be capable of processing, in order to give you 6 ACH. So if your room is 2000 cubic feet, you want an air purifier rated for 200 CFM. Or you could get 2 smaller air purifiers whose combined CFM is 200. (By the way, the CFM of an air purifier is always how many cubic feet per minute it can process when set on high. If you set it on med or low it will turn over air more slowly.)
It is not necessary to get an air purifier with a charcoal filter or ultraviolet light.
Here are some air purifiers on Amazon that get good ratings and give a good amount of air processing for their price.
Reddit is going to run all this together, but it should still be understandable: For each air purifier I gave name and make, CFM, and price. Coway Airmega AP-1512HHS (AP-1519P) HEPA Air Purifier 233 cfm. $266 Coway AP-1216L Tower Mighty Air Purifier with True Hepa 213 cfm. $189 Coway AP-1512HH Mighty Air Purifier with True HEPA 233 cfm. $199 Honeywell HPA300 True HEPA Air Purifier, Extra-Large Room 226 cfm. $300 Honeywell HPA200 True HEPA Allergen Remover 168 cfm. $200 Honeywell HPA100 True HEPA Air Purifier 100 cfm. $100 Honeywell 50250-S True HEPA Air Purifier 250 cfm. $216 Germ Guardian True HEPA Filter Air Purifier 68 cfm. $68

So, open your wallets and enjoy Diwali shopping!

HI guys, I really wish I was further ahead on the curve this one. Last week I stumbled across an article that went viral. Written by scientists, they said air purifiers, as we move indoors for the winter, are key. We don't need covid particles hanging in the air, let's filter them out, makes sense, right? So I started googling, learned from more scientists that this is a smart move, was gearing up to buy one.
Sold. Out. Every single store was already sold out. And I'm in Phoenix, a desert, where we go against the grain. Cooped up all summer, we can't wait to open our doors and go outside. Yet, still, sold out. So if you are elsewhere, reading to move more indoors for the winter, you might want to start looking, well, yesterday. But definitely NOW.
Here's a couple links for you to learn more:
From NPR: Is It A Good Idea To Buy An Air Cleaner For My Home?
From CDC: Newly added recommendation to get an air purifier and what to look for
Air purifier that kills 99.9% of the coronavirus sees surge in global demand
Personally, I am all in. And I'm excited. I live with a high risk person and we will have guests soon. One scientist in the NPR article described how they had a high risk health worker in their home. They opened the windows in the morning (the outdoors is the best purifiers, is what he said), they also had two air purifiers in their home. One in main living spaces, and one in the guest room where this person stayed. They made it work.
I think this is really important news that we are going to hear more and more about it. One scientist literally said, ditch the lysol, people. Just wash your hands like we all should be doing anyway. We really need constant updates on what scientists are learning so we can adjust.
Here's what I'm reading, which you guys are smart, but I'm going to list it anyway:

• Wear a cotton two ply mask. Forget the neck guard, the filters, just a cotton two ply, firmly covering your mouth AND nose, please. And wash it after each wearing.
• Socialize outdoors. Don't go into bars, churches, anywhere with huge groups of people inside.
• Get an air purifier. (A lot of requirements to look for, though. HEPA, etc. I'm educating myself right now and, man, am getting a headache. Nothing is easy.)
• Get a flu shot, early October so it lasts throughout the toughest winter months. If you have elderly people in your life, make sure they get the one made for seniors.
• Keep socially distance, 6 feet. Keep that up.

​
So, knowledge is power and I hope I can find a purifier.
I'd love to hear if any of you have either bought one and or now considering it? Thanks, stay well.

I started to research air Purifiers online about 7 months ago. I am a heavy Cigarette smoker with Asthma and COPD. I know I'm a jack-ass for still smoking. However I did extensive research on these. I wanted to buy the IQair 899.99 version from Amazon, however it wasn't available to residential delivery so I opted for the mother load GC MultiGas system. I have owned 12 plus air Purifiers and never has one worked so good. It has three filter system which consist of a Pre-hepa Filter on the bottom. Then runs to the canisters and then the 3rd level of protection is the Outer post filter. I will admit that I run this puffier 24/7, and your supposed to run it 10 hours a day at level 3. Even though the filter settings in the computer says to change out every X hours. I change it once a month, which cost 50.00 on Amazon. No big deal. However My post filters that surround the GC GAS Canisters have had excessive smoke build up. I have emailed into IQair and they just say go by the settings on the computer. However If that much smoke if going through 2 levels of protection then I think its time to change out the canisters. Its been 6 months since I purchased it. And the website says "Cartridges last up to 2.5 years with average daily use (10 hours a day using speed 3)". I run it at level 6 for 24/7 So That makes my canister life 6 fold. I will admit that I breath a whole lot better running this GC MultiGas system. A key selling feature was the size of particles this purifier picks up. Its much smaller than the COVID -19 size. That was. huge selling feature. However the canisters and post filters are $500 bucks. SO that turns my monthly investment into 134.00 a month. Is it worth it, yes it is, But still expensive. I live in San Diego and leave my windows open at night for the ocean breeze. Attached is a picture of last months After 6 months post filter. One would only guess if that much smoke is penetrating a HePa Filter and GC gas canisters and then turning the 3 layer of defense brown, then its time to change out the Canisters. I plan on doing this today. Every month when I change the Hepa filter, I unplug it put long sleeve shirt on and nitrile gloves and change it out. This way if there is any Covid-19 I am protecting myself. I am interested is knowing how other users feel about this unit. IS 139.99 a month too much to keep my air clean? I have written into IQair support three times. I will give it a change of canisters today ($400.00). And new Hepa filter and see if I notice a change.

The political pundits going on about how schools need to reopen so that disadvantaged kids don’t fall further behind are just trying to sound reasonable and empathetic while they insist that we keep the economy running as usual, exponential growth of cases be damned. I find it hard to believe that they care about education at all.
Wisconsin is a COVID hot spot right now, even considering in-person school starting up next month is irresponsible and considering the long term social and economic damage that a prolonged spike in infections would cause, I just can’t understand the rush to reopen, even from a strictly business point of view.
Here’s my take: I just taught online summer school, and the kids who did well in school also did well online. The kids who didn’t do well in school also didn’t do well online. Assignments are just as mediocre and uninteresting as they were in person. We use smartboards and Chromebooks in the classroom, so using Slides presented over Zoom for kids to watch on their Chromebooks is hardly a big difference.
Furthermore, Milwaukee County has the highest number of cases. It also has the highest concentration of black and Hispanic people in Wisconsin. And the highest risk racial groups for COVID are black and Hispanic people, especially those in lower income brackets with limited access to healthcare. And low income black and Hispanic kids are disproportionately more likely to attend schools that don’t have expensive amenities like updated HVAC systems, no-touch sinks & soap dispensers, spacious classrooms, or even functional windows. These already underfunded schools will not be able to provide extra janitorial staff, extra cleaning supplies, appropriate masks for students who need them, plexiglass dividers, new HEPA filters and air purifiers, and additional space for social distancing. Low income parents are also less likely to want to send their kids back to school, and with good reason: they love their families and don’t want them to get sick or die, and they know that schools are not ready to make the changes needed for safety. They know this because schools were already struggling to give their kids an equitable experience before COVID.
There was a time to really care about educational equity and the overall quality of education in general, and that time was before our country became the epicenter of a pandemic. Attending school wasn’t worth dying for last year and that’s still true today. People are just trying to stay alive and healthy, so fractions and book reports can either be learned online or they can wait. Education is just going to have to stay on the back burner for a while longer.

Hello! My husband and I are feeling incredibly upset at the moment with what is going on, and I guess I'm just looking for some advice.
We adopted the sweetest 6 year old 41lb Golden retriever cross (we're thinking more like shiba inu but I digress) at the start of June. We've been wanting a dog for ever, however we always came to the conclusion that we didn't want to bring a dog into an apartment, especially in LA. Well in February we moved to Colorado, and moved into a much bigger apartment, so we weren't feeling the same way about a dog and were considering it more and more.
I was browsing local shelters online and found our sweet dog - who was apparently amazing with cats, and just a little love bug. She seemed perfect. I called in and asked about her - she had had a double mastectomy earlier in the year (and was given a clean bill of health), and i guess because of the surgery also developed arthritis. When we went to meet her, it was a particularly hot day and so when she came out to the yard to meet us, all she wanted to do was go back in. We therefore decided to trust what everyone was telling us about her and adopt her anyway.
Well! Everyone was right. She has been so good, the easiest dog ever. Is already house trained (though doesn't tell us when she needs to go so we have to stay on top of that), is so gentle and respectful of our cat (who we've had for 6 years, having adopted her when she was 4). A little lazy but it's still early days so we're trying to encourage gentle exercise to help with the arthritis. She has totally attached herself to me, which I think bums my husband out a little bit. In almost every way she is my perfect dog. Doesn’t lick, doesn't bark, is housetrained, so sweet and gentle, learning how to play lol. Perfect EXCEPT for one thing.
Ever since we brought her home, our cat has had asthma attacks every night but 4-5. That's 4/5 days out of 22 that she has not had asthma.
Now, we knew she had asthma before this. When we were living in LA, she would get them from time to time, but when we moved to Colorado in February, she didn't have a single asthma attack, which was such a relief.
Now that she's having asthma attacks on the regular (and more frequently than she ever had before) we are at a loss at what to do.
We bathed our dog, bought a new fancy Dyson vacuum with the HEPA filter which we now use every day, bought an air purifier, wash the sheets much more regularly, humidifier on, cover our pillows with the flat sheet during the day... (also the dog doesn't go on the couches or bed so we didn't have to change that) (edit to add that we have also flea and tick treated both pets)
We have her booked for a groom on the 4th of July (because of Covid, all groomers were incredibly backed up) where she will have her undercoat i guess power blown out (we tried our best with a rake and regularly brushing, but she still finds areas that need "plucking"), anti-shed shampoo, and her feathering trimmed. After that... if that doesn't help, we are going to have to seriously talk about rehoming her which absolutely breaks my heart.
It doesn't help right now that we (though my husband significantly more so) are going through the apparently normal process of post adoption freak out and wondering if we made the right choice. To add our cats health on top of this, I am absolutely broken.
Our cat is our absolute baby and to see her suffering like this makes us feel so guilty. But then we also feel incredibly guilty at the idea that we'd have to rehome the dog.
Does anyone have any advice? Anything you think we might have forgotten to do?
We're so ridden with guilt right now. I really thought we could be a great home for her, and a part of me is happy that we were able to give her a good place to be outside of the shelter.... but she's had such a rough go (was transferred to CO from a NM kill shelter) I had just hoped that we were the ones to be her forever, and the idea that we might not be is really hard for me to deal with.
Help please!
Adding that we have a visit with the vet on 7/7 where we will enquire about an allergy test and potential vaccine. If anyone has other suggestions outside of this is would be greatly appreciated! Or any information on the process for a feline allergy vaccine - ie frequency, cost, success rates etc.

Welcome to Masks4All !
**This Megathread is a work-in-progress** We emphasize that this is indeed, a "masks for all" subreddit. That means we want to foster a community which reflects this central goal; this is a place for anyone, of any background and belief system to set aside their differences and focus on a topic that benefits us all, regardless of those differences: no matter who you are or where you are; we assert that creating, wearing, and promoting masks is an integral part of resolving the COVID-19 pandemic. This is backed up by heaps of scientific, peer-reviewed research. We are not here to debate the merits of that, as it's counterproductive to what is necessary to stop this global crisis.
While not officially related we have a very friendly working relationship with Cam Woodson of https://masks4all.co/ which is the most up to date and comprehensive resource on this subject. They cover the science behind masks, frequently asked questions for skeptics, and why we advocate for mask laws (think seatbelts - how there is an actual punishment for not wearing them) and not just recommendations.
That website and this subreddit and our affiliated Discord ( https://discord.gg/EdFECkB ) was inspired by the March 27th 2020 video put out by Petr Ludwig of the Czech Republic, a country that very quickly and effectively mandated masks relative to most other countries. Here is the link to that: https://www.youtube.com/watch?v=HhNo_IOPOtU At this point in time, there are near endless methods to create a mask, so there is little reason to wait until they are available to buy in stores - almost everyone has the available materials to have at least some face covering, and as you can see in the following study, many household materials have at least some efficacy: https://www.ncbi.nlm.nih.gov/pubmed/24229526 https://i.imgur.com/lEKzjrQ.jpg

Additional info behind masks:
“Once 80% of the population wears a mask, the spread of a virus during a pandemic can be stopped almost immediately.”
From a 2019 Research Paper on Stopping an Influenza Outbreak, cited on Masks4all
There are “34 scientific papers indicating basic masks can be effective in reducing virus transmission in public — and not a single paper that shows clear evidence that they cannot.” –The Washington Post
“In a paper published in Nature on Friday, a five-year study from the University of Hong Kong and the University of Maryland has found that a simple non-fitted mask blocked 100% of coronavirus droplets and aerosol.” –The Guardian
References: http://files.fast.ai/papers/masks_lit_review.pdf https://www.nature.com/articles/s41586-020-2196-x https://docs.google.com/document/d/1HLrm0pqBN_5bdyysOeoOBX4pt4oFDBhsC_jpblXpNtQ/edit#heading=h.9yzpxufkt5ow https://www.youtube.com/watch?v=2xLjCfmx0iE
Common Fallacies:

1. "You can still get sick" - masks are to 'prevent YOU' from potentially spreading germs as many asymptomatic or mild cough (it's just a bit of a stuffy nose, right)?
   
2. "It promotes a false sense of security" Assuming the public, that in many cases has socially-distanced themselves BEFORE government requirements, will just all the sudden decide that they should be more reckless even though the act of wearing a mask is more of a precaution. It's akin to saying seat belts will encourage people to drive less safely because they will feel protected by their seat belt. And as an aside with seatbelts, unless there is a punishment, like not wearing seatbelts a mask requirement is not a mask requirement by a “recommendation”.
   
3. "Doctors and nurses need them" agree they do. Again, nobody is recommending to hoard N95 masks. Besides. N95 masks don't have to be disposable - they can be sanitized. See above.
   
4. "It doesn't excuse social distancing" Nobody said we should stop social distancing, but people need masks when they work, when they go on runs for essential goods, etc.
   
5. "A mask if you feel it necessary, but not necessarily a mask" Like Social Distancing, this is only really effective if everyone does it. Most people aren't infected and if we don't know who the asymptomatic spreaders are, it needs to become a norm.

“N95 Face Mask Template”
Reddit post describing a DIY N95 face mask.
https://www.reddit.com/COVIDProjects/comments/fl38n7/n95_mask_template/

There are a small number of posts and papers that (while not related to COVID-19 specifically) outlines some of the supplements that might help keeping your immune system up and running during this pandemic.
These are NOT going to cure a virus infection if you have one (go to hospital instead to get professional treatment), but some medical experts call these vitamins, supplements and minerals "essential for immunocompetence", and so while we're all caged in our rooms for the following weeks, I think its good practice that we stock up on them just in case.

• Vitamin A
• Vitamin B Complex
• Vitamin C
• Vitamin D
• Iron
• Selenium
• Zinc
• NAC (n-acetylcysteine): 600 ~ 1200mg per day, Another reddit post about NAC in regards to COVID-19

All the others have a recommended daily intake amount so just following that would probably suffice (from a multivitamin pill or separately).
Also it its known that air purifiers with HEPA-equipped filters can definitely capture the coronavirus (0.01 micron and higher, and the coronavirus is about 0.125 microns, so yeah), and it would be a plus if your purifier has a UV-C light internally as it can effectively destroy viruses by disrupting their DNA, leaving them unable to function properly and thus die.
Of course, the focus of this viral spread is more person-to-person contact more than an air-transmission, so keeping your hands clean and disinfecting phones and keyboards daily would also be good practice.
