A balanced response, based on AirGreen’s HVAC expertise
In an urban context like Montréal, where air pollution, allergens, and excessive humidity can significantly affect indoor quality of life in residential and commercial buildings, the topic of air purification deserves serious attention. Far from the marketing gimmicks that play on fears related to air quality, we at AirGreen approach the issue from a technical perspective, grounded in our ventilation and air treatment expertise—with a concrete, tailored, and proven approach from the field.
Why is indoor air quality a priority in Montréal and surrounding areas?
Large cities like Montréal, Laval, and Longueuil are regularly exposed to smog episodes, high pollen levels, industrial emissions, and fine particles from traffic. This outdoor pollution, combined with poor indoor ventilation, creates unhealthy environments in many homes and commercial buildings.
Moreover, the long, harsh winters on the North Shore and South Shore often lead residents to keep windows and doors shut for months, which worsens the accumulation of volatile organic compounds (VOCs), dust, mold spores, and humidity. In this context, air purification, when part of a full HVAC strategy, makes a lot of sense.
Standalone air purifier or integrated purification system: which is best?
The drawbacks of portable purifiers
Many consumers are drawn to portable air purifiers sold online or in big box stores. However, these units often have limited treatment capacity, low-quality filters, and insufficient airflow for a full room—not to mention near-total inefficiency in large spaces.
As HVAC professionals, we do not recommend relying solely on these devices when real health concerns are at play (asthma, severe allergies, respiratory conditions).
The AirGreen solution: centralized air purification
At AirGreen, we integrate professional air purification solutions directly into the ventilation system. These include:
-
The addition of high-efficiency HEPA filters, capable of capturing up to 99.97% of fine particles.
-
Installation of UV-C lamps in ductwork to neutralize bacteria, mold, and viruses.
-
Integration of heat or energy recovery ventilators (HRV or ERV) with smart sensors to constantly and intelligently renew indoor air.
-
Use of bipolar ionization systems for large commercial projects or high-density buildings.
Real AirGreen interventions across Greater Montréal
Residential project in Villeray, Montréal
A couple suffering from chronic seasonal allergies contacted us to improve the air quality in their century-old home. After a thorough evaluation, we recommended installing a Venmar AVS® HRV system with integrated HEPA filter, paired with a Lennox Healthy Climate® UV lamp. The result: noticeable symptom reduction in under two weeks, with fresher, drier air and no lingering odors.
Commercial project in Laval
In a children’s care center, the frequent spread of viruses and persistent odors was a concern. We installed a Lennox PureAir™ centralized filtration system, combined with active PlasmaAir ionization. With continuous air purification, the management saw a significant drop in health-related absences and an overall improvement in indoor comfort.
How do you know if air purification is needed in your building?
Here are some clear indicators:
-
Recurring persistent odors (mold, cooking, pets).
-
Frequent condensation on windows (high humidity levels).
-
Ongoing or worsening respiratory symptoms (coughing, congestion, allergies).
-
Dust buildup despite regular cleaning.
-
Old HVAC system, with no air renewal component.
In these situations, a personalized HVAC assessment from AirGreen is highly recommended. We conduct a full evaluation of your ductwork, relative humidity, air exchange, filtration system, and propose a customized solution tailored to your home or commercial building.
What are the real benefits of an integrated air purification system?
-
Improved respiratory health for all occupants.
-
Reduction of allergenic particles (pollen, dust, pet dander).
-
Elimination of chemical pollutants (VOCs, formaldehyde).
-
Prevention of mold and bacteria in air ducts.
-
Longer lifespan for HVAC equipment thanks to cleaner air.
-
Better energy efficiency performance by minimizing losses due to poor filtration or humidity.
Grants available in Québec for air purification systems
While standalone air purifiers may not always qualify for grants, several programs like Hydro-Québec’s LogisVert or Rénoclimat do cover heat recovery ventilation systems and ventilation duct upgrades as part of energy efficiency renovations. We assist you in analyzing your eligibility and preparing the required documentation.
