Indoor Air Quality
Improving the quality of the air you breathe in your home must be viewed as an investment in your family’s well-being. There are many high quality filtration systems in homes that are compromised by inadequate filters or disconnected because they were found to be expensive to run. If you purchase an air quality component for your home heating and cooling system, research the maintenance costs before paying the installation price.
Why would you want to install an air quality filter on your system?
Because the air in your home is 5X dirtier than outdoor air.
Because everyone has a limited physical tolerance for airborne chemicals and particulates.
Because an air quality system will greatly reduce the contaminants ingested into your body.
The contaminants in your home consist of bacteria and viruses, dust mites, animal dander if you have pets, volatile organic compounds which are gases released from household materials and liquids, and bio burden which is biological material in the air, living or dead. Airborne particulates are measured in microns which are 1/25000 of an inch in size.
Most furnaces have a filter attached on the return air inlet. Most are sufficient to protect the furnace and air conditioning evaporator coil from dirt. But you can install cartridge filters that have the capacity to improve the breathing quality of the air in the house. These filters are rated by how few particles are able to pass through them. The rating system is called the Minimum Efficiency Reporting Value or MERV.

MERV and HEPA Filters
A MERV 10 filter removes 85% of particles like dust and pet dander and mould spores down to 3 microns. This is a good filter for many people and will produce noticeable differences for people with seasonal allergies.
A MERV 16 filter however will remover 95% particles down to 0.3 micron and 90% of bioaerosols and microorganisms down to 0.01 micron. This filter will provide relief for people with more serious bronchial difficulties. It provides efficient removal of all lung irritants. This is our most popular air quality solution.
A HEPA filter is a bypass system that requires the furnace fan to run continuously. These filters are 99.97% at removing particles and bioaerosols down to 0.3 microns. It is this technology that is used in hospital critical care rooms and it can be installed on your home duct system.
Lennox PureAir Systems
The Lennox PureAir system specifically targets all three classes of contaminants. It removes 90% of bioaerosols down to 0.01 micron including viruses, dust mites, bacteria, mould spores and fungi.
You can also introduce outdoor air into your home via a heat recovery ventilator( HRV). Tightly sealed homes require an HRV. These homes cannot reclaim fresh air from the outdoors to balance indoor usage. An HRV can also be used to balance humidity levels in homes where moisture is an issue.
