The truth about the real effectiveness of air exchangers against viruses, according to AirGreen's expertise in Montreal
With growing concerns about indoor air quality, many homeowners in Montreal, Laval, Longueuil, the North Shore, and the South Shore frequently ask us at AirGreen about the effectiveness of their air exchanger against viruses, especially since the COVID-19 pandemic. Today, we provide a clear and definitive scientific answer to this crucial question, based on technical facts and our direct field experience.
The precise role of an air exchanger: understanding above all
An air exchanger is primarily designed to continuously refresh indoor air by expelling stale air outdoors while simultaneously bringing fresh air indoors. It effectively reduces humidity, chemical pollutants, allergens, and fine particles, significantly enhancing overall indoor air quality.
However, specifically regarding viruses, the ability of an air exchanger to protect your health depends heavily on several technical factors, which we detail precisely here.
The scientific reality about air exchangers and viruses
To be clear: no standard air exchanger alone completely eliminates viruses. However, by regularly renewing indoor air, it effectively dilutes the concentration of potentially present viral particles. Thus, it significantly helps reduce the risk of airborne viral transmission, but only if it is correctly installed and adjusted.
Here are the key parameters influencing this effectiveness:
-
Air renewal rate: The higher the rate, the more quickly viral particle concentration is diluted.
-
Quality and type of filters used: HEPA or high-efficiency filters can capture viral particles, further reducing their spread in the home.
-
Rigorous maintenance: A poorly maintained exchanger quickly becomes inefficient or even dangerous, by retaining and redistributing potential viruses.
AirGreen case study: Installation of a Venmar AVS X24ERV ECM air exchanger in Montreal
To concretely illustrate our points, here is a precise example from a recent installation we completed in Montreal, featuring a Venmar AVS X24ERV ECM air exchanger. Our client, concerned about indoor air quality and their family's health safety, wanted to maximize virus protection.
Our technicians undertook the following measures:
-
Installation of a Venmar AVS X24ERV ECM air exchanger, renowned for its high energy efficiency and certified filters.
-
Addition of high-performance HEPA filters capable of capturing up to 99.97% of fine particles, including certain viral particles.
-
Precise adjustment of airflow rates to ensure rapid and constant air renewal, drastically reducing potential viral concentrations.
Result: The client observed a noticeable improvement in air quality, confirmed by independent tests, as well as a significant reduction in allergic and respiratory symptoms among occupants.
Mistakes to avoid ensuring antiviral effectiveness of your air exchanger
During our interventions in Laval, Longueuil, and surrounding areas, we regularly observe errors significantly decreasing exchanger effectiveness:
-
Prolonged use of standard or saturated filters.
-
Inadequate settings limiting sufficient air renewal.
-
Neglecting regular maintenance, promoting the growth of contaminants.
