The ability to reduce or eliminate odors and gases in an occupied area has been a challenge for contractors, architects, environmental engineers and HVACR professionals for years. This problem persists in many forms and in many areas in the residential, commercial, institutional, industrial and medical arenas.
In the past thirty years a number of odor and gas reduction/removal processes have been employed to resolve these problems. Of all the products and techniques that have been tried two methods are the most often considered and only one of these two methods provides any real reduction or removal.
Ozone is easily produced. Simply by applying a small amount of electricity in a spark form you can transform Oxyen (O2) into Ozone (O3). Ozone is produced naturally when there is lightning. If you are outside close to a lightning strike you can often smell the ozone produced by the lightning. It almost has a sweet, fresh air smell.
Activated Carbon or Charcoal has a natural affinity to adsorb (not absorb) gases and odors that are both organic and inorganic. Activated carbon has a very large surface area that captures and holds most gaseous molecules until the carbon is saturated then it will release the excess gaseous molecules.
Ozone is a strong oxidizer. Ozone easily gives up one of Oxygen elements which can alter the chemical composition of gases. Ozone is often referred to as “energized oxygen” or “pure air” suggesting that ozone is a healthy kind of oxygen. That is far from true. Ozone is a toxic gas with vastly different chemical and toxicological properties from oxygen. Ozone can be harmful to the respiratory system and is the primary component of smog.
While carbon does have a finite life and adsorption capacity, it actually removes or significantly reduces the gas or odor completely. Unlike Ozone which may only change the gaseous molecule to another form that may actually be more harmful than the original odor problem, Carbon is benign and removes the harmful odors and gases without producing any health problems for individuals.
Pure Air Systems manufactures a complete line of carbon based systems that can hold from 10 lbs of carbon up to 60 lbs of carbon. These units are designed to work in all types of applications whether it is residential or commercial. These units are fan powered and can handle up to 2000 CFM of contaminated air with excellent first pass reduction of odors and gases.
