How Can I Control The Quality of My Air?
There are three main strategies to control your Indoor Air Quality, the 1st, and usually the most effective, is "Source Control".
This involves trying to eliminate individual sources of pollution or to reduce their emissions. In many cases, source control
is also a more cost-efficient approach to protecting indoor air quality than increasing ventilation because, unless an Energy
Recovery Ventilator is installed, increasing ventilation can increase energy costs.
Increase Ventilation Levels
The 2nd strategy is increased Ventilation Levels, or more simply, bring more Outside Air into your Home. In most cases, your Home's Heating & Cooling
Systems, will not have the proper equipment and controls to bring fresh air into the house. A Mechanical Ventilation System can be added to bring in controlled
amounts of outside air when needed. A system that includes an energy-efficient Energy Recovery Ventilator, also known as air-to-air heat exchanger can
provide this outside air while reducing Energy costs by up to 80%.
High Efficiency Air Filtration
The 3rd strategy is filtration - There are many types Air Cleaners available, ranging from relatively inexpensive table-top models to highly
efficient whole-house systems. Some air cleaners are highly effective at particle removal, while others, including most table-top models,
are much less so. Air cleaners, with the exception of the Lennox PureAirTM Air Purification System are
generally not designed to remove gaseous pollutants.
The effectiveness of any Air Cleaner depends on how efficiently it removes pollutants from indoor air, expressed in a MERV Ratings
(A higher MERV Rating removes smaller particles) and how much air it draws through the cleaning or filtering element. A very efficient
collector with a low air-circulation rate, such as table top models, will not be effective, nor will a cleaner with a high
air-circulation rate and a low MERV Rating. The long-term performance of any air cleaner depends on maintaining it according
to the manufacturer's directions.
