One-inch equals 2.54 centimeters (cm) so one cm equals about 0.39 of an inch; Divide the cm by 10,000 as well as the result is one micron.
Dividing the micron by 1,000 yields the component of distance known as a nanometer (nm).
Divide one nm by various as well as you have the approximate width of an oxygen molecule (O2), then in the air, the closest neighboring O2 molecule is about 4 nm away or the equivalent of about 25 feet for a human with a more than one-foot width. Thus, O2 maintains ample space between molecules for correct social distancing at the atomic level. O2 is just 20% of all the gases that occupy the atmosphere leaving plenty of room for nitrogen, the most prevalent component of air at 74%. The rest is carbon dioxide, water vapor, as well as other trace elements prefer argon as well as neon. At higher altitudes, gases prefer ozone, helium, as well as hydrogen are found. When air enters our homes as well as passes through a central Heating as well as A/C system, the component gases are unchanged. The one exception is water vapor that condenses into liquid water as the air is cooled. The two of us all appreciate the cooled air at lower humidity, but the tscheme “conditioning” aspect of the Heating as well as A/C idea is the removal of all the other stuff that is floating around in the air. This includes polluting chemicals, pollen, dust, pet dander, mold spores, as well as even airborne viruses that get lifted into the atmosphere. Removing these substances is left to the humble filter that is so often ignored but is the most important component in cleaning the air so all of us can breathe in as well as extract the life-giving O2. This is why Heating as well as A/C professionals are constantly reminding homeowners to change their filters respectfully in between respectfully tied up repair calls.
