Opinion on Reme Halo? Thank you!
Hello Professor Allen! Finding I was allergic to the linoleum SMELLS in those new " Fake Leather" seats in cars, has encouraged me to want to live on DIRT floors! Add a bit of sand from the beach to give the floors that great aroma too? Ha- way to treat your feet, too, without going to the gym ? But you can't argue with those Stoneware frying pans! (No grease, just real butter and olive oil. though)
Great show, great terms...wakimos', right ?! Isn't that a great name for what one does WITH that frying pan, too, when your husband comes in to tell you how to cook his dinner ? Yep. Wakimo's. Got to stop giving marketing these newfangled IDEAS, right ?
Now you'll understand
"You're the Reason I'm not Married ?" and
"Stand by Your Man if you Can!"
"Devil be Gone With the Wind" to empower the children against all of those big ugly threatening WORDS ? Dr. Campbell's advice (UK) with whom Medcram spoke last month, suggested " Fresh Flowing Cool Air" to warn off the virus; (So American closed its beaches ?) I find that ironically hilarious.
So first off. While using a fan and a HEPA filter can help in an emergency. They do not circulate the air well enough and are not effective in saving on your electric bill. Air purifiers are designed to filter the air effectively and efficiently, also carbon filters aid to remove gases and odors and can remove the smallest particles (gases, 0.01 particles, etc) as well as the aid of a HEPA filter. The other thing is that uv light can destroy viruses and do it without ozone production if they are CARB certified and also use mercury in their bulbs. HEPA filters that have a high MPPS (most penetrating particles size) percentage are your best best when it comes to efficiency. As for ionization, ionizers are perfectly safe as long as they meet CARB standards or UL standards. If they have a carbon filter, they can also reduce the ozone that is produced, which is less than a phone basically. Also, if an air purifier has a "sealed system," (rubber seals to prevent particles escaping from the gaps between the filters and the fan.) That is a huge plus. If you are dealing with gases and heavy oders, then you need lots of carbon, in the pounds to be exact. If you need something for asthma and allergies, a HEPA filter with a small carbon filter will be perfect. And always look for True HEPA. HEPA type is a cheaper and less effective version of HEPA, good for dust but nothing really much else. Medical grade filters have a high MPPS, they can capture particles at the smallest size more accurately than other HEPA filters, but will cost more. Regular true HEPA, (h11 or 12) medical grade (h13 or 14). For a HEPA filter to get a legit medical grade rating it needs to be confirmed by these labs (IBR, Camfil, LNS, SGS,) those are some of the big boys in the Field. Also, if consumer reports tested the purifier, AHAM, Intertek, or the AAFA, BAF, Or nordic asthma and allergy (all certified for scientific confirmation, you're getting a legit product. All HEPA filter can capture covid sized particles, but will not prevent you from passing it on via droplets from the nose and mouth, but can reduce particles in the air in a sealed room in your home. The higher the HEPA grade, the more efficient they are, or at least the higher the MPPS is, the better they are. Most of the info I just told you came from two MIT engineers and a filtration engineer who worked for a company called IQair, which produce purifiers for hospitals and cleanrooms. He also works at a company called Aeris, which is a medical air cleaner company. As well as talking to many other engineers, many articles with real studies like from Harvard, NASA, etc. If you really want to know about air filtration, check out Oransi, probably the only brand I'd trust, mainly from their extensive industry standard certifications as well as their partnership with MIT, NASA, Google, Texas A and M and have a legit knowledge data base that I haven't seen from anybody else. The CEO of the company worked with ALEN corp, which engineers worked for NASA, so I'd say maybe it's something to check out. Stay safe. Also, cheaper doesn't mean better. The cheaper you go, the more malfunctions, breakdowns, inaccuracies with sensors you will have, anything less than 400 is going to suck. I would know, I have owned many leading brands that are under that mark, compared to higher prices ones. They fall apart within about 3 to 4 years if not taken care of, which most don't.
Should I listen to the Harvard School of Public Health Director that said exactly the same thing other scientists from other countries have said or to a total stranger on the internet that clearly knows nothing about science and is filled with uneducated asumptions about how things work, that came of course from marketing of capitalist companies?
What to do, what to do, such a hard decision...
@@TheGoodContent37 You should listen to both and make your own decision. Since ive done years of my own research, talking to people who worked at Dyson, Blue air, AAFA (asthma and allergy foundation of america) Aeris air purifiers (developed by two MIT graduates who have people who have worked for swiss purifier company IQ air). I've talked to doctors, ive read more than you probably would be comfortable with on air purification, and as an asthma sufferer, I know what works. My father used to have an ozone generator. It fucked with my lungs horribly. So I know what is safe, what isnt what works, and what is a scam. You should't throw away ideas because somebody doesn't have a degree. I get your view point. I myself have had the same idea. I always listen to people with degrees, and years of licensed experience. However, just because its science, doesn't mean it isn't old science. We should be open minded, look at new things, and test them out, see reviews, etc. Use critical thinking. I agree with you. Can one use a box fan as a purifier, yes. It does work. However, I have seen how they produce the high grade ones, and there is a legit reason they cost as much. For one, they last longer depending on the company (should always do your research) Two, they are efficient, energy wise. They are designed to move air efficiently without being loud. And if designed correctly they will prevent leakage if they have a sealed gasket. They also can filter things very efficiently because they are designed that way, the way the fibers are designed how thick they are, the carbon filters that are in there, etc. I didn't skim through anything, I legit asked every single company I could think of, called them, emailed them. Watched videos on them. I own two very high quality ones, and they work very well. But do your own research, of course.
Gosh, you are really trying to help humanity THINK aren't you ? Good for You; Now I'm reminded it might be time to actually CHANGE THE FILTER on ours?!

All fairly accurate except missing a ton of info like particle size of covid, and the fact that some brands have tested 1 model for actual covid and some are approved by government agencies. Also there was a study in Europe i. covid wards using 2 specific brands of air purifiers that proved they worked 100% and both had UV. I disagree with you that cheaper is not better or the same. I own IQ Air purifier $900, Blueair, $400, Whirlpool (top rated consumer report), and other cheaper small ones. Now that I know what I know about air purifiers, there are a few on the market for around $250 as good as some worth 600. H13 level, UV, over 450 CADR, Carbon filter and ionizer. And you can catch some expensive ones one sale for around $300-$350 that were once $550.
@@nomad1517I have asthma pretty bad myself. I can’t decide between the Aeris AAIR 3 in 1 for $1,200 or the IQAir HealthPro at $899.
