Best Air Purifiers and HEPA filters: Harvard Professor Explains What to Buy For COVID 19 and Beyond

1. 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.

3. 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.
