The AMA and the ADA have the power to shut down any doctor/dentist not OBEYING them. When they order unnecessary facemask mandates, We the People don't get medical/dental services unless we wear masks.

That's TOO much power over people.

While it is a minor virus, it is not a cold virus. Those are from the rhinovirus series. Covid19 is from the SARS/Covid series. Flu is from the influenza series. SARS/Covid series viruses have often been called 'the flu' before by the CDC and others.

It's symptoms are very much like a common cold. It's infection vector is very similar as well.
Just as with the common cold, masks will stop it.

There are two coronaviruses in the group, we call the 'common cold'.

Living in Florida during the pandemic has been interesting. Our governor is anti-mandate, let the people and businesses decide. There are some things, his hands are kind of tied on, if he wants in on federal assistance, which can use to help out those who wish to adhere to the CDC guidelines. Not to mention, some things like government run stuff, need to follow the guidelines. After the initial 30 days lockdown, we opened up the beaches. We were ridiculed and warned of huge spikes. Never happened. Beaches made good sense, and minimal risk. Hot, sunny, UVC rays, saltwater... All very hostile to viruses. We opened bars, which, you know aren't going to follow an guidelines too closely. Most, are doing okay, and seem to be about normal. Orange County (Orlando) is run by democrats, Jerry Demmings, and he has a compliance task force, and encourages people to tattle. His wife, is Rep. Val Demmings, elected 2018, and was part of the impeachment team. Mostly, even with our loose compliance, we aren't doing any worse than the Nazi states, better than many. The virus is going to spread, regardless of what we do. The vaccines aren't going to save us, although it's likely to be called a victory, around the end of next year. The numbers will drop off, mostly because fewer tests given. I figure on another 2-3 years of outbreaks, before it really calms down.

3 micrrons, as specified in the N95 spec. These masks will stop 95% of particles 3 microns and larger.

What is the exact spec for the N95 mask? I keep reading from everywhere that it is 0.3 microns. Still bigger than the coronavirus but the diference is not as dramatic as I initially though.

N95 is .3 microns.
Covid viron is 120 nanometers
....so 25 times smaller.

Neither will cloth masks, or bandannas, or neck gaiters, or anything else that you typically see people wearing around.

The use a different type of respirator, is it's the patient, who poses the risk of infecting the health care workers. The masks worn in hospitals and clinics, aren't one size fits all. If you ever noticed, most of the 'mask-wearers', have gaps on each side, some large enough to insert an index finger, (like my cloth masks) even the paper masks. The mandates are only that the face must be covered, not covered effectively.

3 microns, not 0.3.
The differences are great.

"COVID 19 virus particle size is 125 nanometers (0.125 microns); the range is 0.06 microns to .14 microns," the post said. "The N95 mask filters down to 0.3 microns.

The N95 is made by various manufacturers under different names, from MSA's "Affinity Foldable Respirator" to 3M's "Particulate Respirator." Look for "NIOSH N95" on the package; the "N95" is a government efficiency rating that means the mask blocks about 95 percent of particles that are 0.3 microns in size or larger.

So which is it?

2.2.1. N95 respirator
These types are a type of FFR masks, are non-oil resistant, also known as electrets filters. The word N95 is obtained from the fact that these types of masks can at least filter 95% of aerosols around 0.3 μm [34].

Apparently those simplest masks which are used the most are not N95 masks. I do not know how they call them.

This is wrong. The N95 spec is 3 microns an larger. False authority fallacy.

Filter Classification
This rule establishes three series of filters; N, R, and P. Each series has three levels of filter
efficiency; 95 %, 99%, and 99.97%. These are the minimum efficiencies to be demonstrated by
each filter. Hence, there are nine classes of filters altogether. Filters will be identified as:
* N95, R95, and P95: 95% filter efficiency level
* N99, R99, and P99: 99% filter efficiency level
* N100, R100, and P100: 99.97% filter efficiency level
The P100 filter will be color-coded magenta.
________________________________________________________________
Test Requirements
The new certification tests use the most penetrating aerosol size, 0.3 µm aerodynamic mass
median diameter, of either a mildly degrading particulate, sodium chloride (NaCl), or a highly
degrading oil, dioctylphthalate (DOP). The efficiency of the filter shall be monitored and recorded
throughout the test period. The N-series respirators will be tested to a maximum loading level of
200 mg NaCl per respirator. The minimum efficiency for the filters tested must be equal to or
greater than the filter efficiency criterion listed above for the filter class for which approval is
sought. For example, after being loaded with 200 mg of NaCl, an N95 particulate filter must
demonstrate filter efficiencies greater than or equal to 95%. Prior to filter efficiency testing of Nseries filters, the filters shall be taken out of their packaging and placed in an environment of 85 ±
5 % relative humidity at 38 ± 2.5°C for 25 ± 1 hours. These preconditioning requirements apply
only to N-series filters. This requirement is to address the effect of humidity on the filter's
efficiency because the sodium chloride aerosol is less severe than DOP in reducing filter efficiency.

Sure, but since we are talking about 3 micron, i.e. an order of magnitude larger, and since the holes are a percentage larger than that, it clearly reveals the sheer ease with which a mere 0.12 micron virus will pass through an earloop mask.

The ratio is congruent to a 6' man trying to "squeeze" through a 150'-tall archway that is roughly 75' wide. It renders absurd the notion that earloop facemasks somehow "help" in this regard.

I agree. Now, the most important thing is to wear masks. It is extremely difficult for dentists, as they have a risk of contracting covid. I am happy that despite the difficult situation in the country, they still help people. Recently, I had serious problems with my teeth (my inflamed was gum). I couldn't eat properly, and so I asked for help from https://jeffreygrossdds.com/. I was afraid that the specialists might refuse to help me because now the situation in the world is quite tense. to my surprise I managed to make an appointment with them. I am grateful to those doctors who, despite the pandemic, help people.
