Specific effects may include throat irritation, coughing, chest pain and shortness of breath, as well as an increased risk of respiratory infections. Some ozone air purifiers are made with an ion generator, sometimes called an ionizer, in the same unit.

Carbon Monoxide Sources in the Home CO is produced whenever a material burns. Homes with fuel-burning appliances or attached garages are more likely to have CO problems Common sources of CO in our homes include fuel-burning appliances and devices such as: Clothes dryers. Water heaters.

Testing the air and installing CO detectors will help keep your family safe. Carbon monoxide (CO) is a highly poisonous gas that can be fatal if inhaled in large amounts. You can’t see or smell carbon monoxide gas, which makes it even more dangerous.

When the carbon dioxide concentration goes up, temperature goes up. When the carbon dioxide concentration goes down, temperature goes down.

Air purifiers do not reduce the amount of oxygen in the air. Activated carbon filters take up some oxygen. However, this is a negligibly small amount. Purifier filters prefer to take up larger, harmful compounds.

An oxygen concentrator works like an air conditioning machine: it takes in air, modifies it and delivers it in a new form. The only difference is that a concentrator purifies the air and makes it available for patients who have low oxygen levels in their blood.

The most common commercial method for producing oxygen is the separation of air using either a cryogenic distillation process or a vacuum swing adsorption process. Nitrogen and argon are also produced by separating them from air.

Liquid oxygen is used as an oxi- dant for liquid fuels in the propellant systems of missiles and rockets. Oxygen is widely applied in the metal industries in conjunction with acety- lene and other fuel gases for metal cutting, welding, scarfing, hardening, cleaning and melting.
