If you use oxygen on a daily basis, you'll need a humidifier to humidify the oxygen in order for a comfortable flow of oxygen humid enough to prevent the nasal cavities from dryness, redness and eventually painful scabbing in throat and nostrils which can cause great discomfort. It is best that a humidifier is used when taking oxygen for an extended period of time.
Hope this helps.

Air is made up of mainly oxygen true or false?
False. Air is made up mainly of nitrogen (about 78%) and oxygen (about 21%), with small amounts of other gases such as argon, carbon dioxide, and others making up the remaining 1%.
Is it true or false The amount of nitrogen oxygen and water vapor in the atmosphere varies from place to place?
True. The amount of nitrogen, oxygen, and water vapor in the atmosphere can vary depending on location, altitude, weather conditions, and human activities. These variations can impact local air quality and climate.
The chemical formula for water H2O means that each water molecule contains?
someone had it roung it 2 hydrogen molecule and 1 oxygen molecules. so it true
What is true about both nitrogen and oxygen?
Both nitrogen and oxygen are nonmetallic elements that are essential for life. They make up a large portion of Earth's atmosphere, with nitrogen being the most abundant gas and oxygen supporting combustion and respiration.
Which of these statements is true about the oxygen revolution?
The oxygen revolution refers to the time in Earth's history when oxygen levels in the atmosphere significantly increased due to the photosynthetic activities of early algae and eventually land plants. This led to the evolution of aerobic organisms that could utilize oxygen for respiration, paving the way for more complex life forms to thrive.
Is this true or false an oxygen molecule usually has 2 oxygen atoms?
True. An oxygen molecule typically consists of two oxygen atoms.
Ozone is a form of oxygen true or false?
It is true. Ozone is an allotrope of oxygen.

What is true about oxygen 17 and 18?
They are both Oxygen.
Do human body consists mostly if oxygen false or true?
Sort of true - its mostly water which is mostly oxygen.
Almost all of the oxygen on the planet earth is found in the atmosphereis this statement true or false?
False. Almost all of the oxygen on Earth is found in the oceans.
Is it true that an oxygen molecule has two atoms?
Yes, that is correct. An oxygen molecule consists of two oxygen atoms bonded together.
An example of a gas is oxygen?
TRUE
Water H2O is composed of hydrogen and oxygen true or false?
True
Is it true or false oxygen released in photosynthesis comes from water?
