How Modern Air Cleaners Can Defend Against Winter Illnesses

Premier Comfort Heating & Cooling • November 25, 2025

As temperatures drop in Ottawa and homes are sealed up tight, winter brings more than just cold weather—it can also usher in a higher risk of seasonal illnesses. Many Ottawa families notice an uptick in colds, flu, and allergy symptoms in the colder months, and with more time spent indoors, indoor air quality becomes a crucial factor in your family’s health and comfort. At Premier Comfort Heating & Cooling, we believe that modern air cleaners are one of the most effective tools to help defend your household against winter illnesses.


Why Winter Makes Indoor Air Quality More Important


During Ottawa’s long winters, we naturally keep windows and doors shut to conserve heat and stay comfortable. Unfortunately, this also limits ventilation and allows airborne contaminants to build up inside, including dust, pet dander, mold spores, bacteria, and viruses. These pollutants can worsen respiratory symptoms, trigger allergies, and help viruses spread more easily among household members.


Dry indoor air is another common winter issue. Low humidity encourages airborne particles to linger longer and can dry out your nose and throat, making you more susceptible to respiratory infections.


How Modern Air Cleaners Work


Modern air cleaners use advanced filtration and purification technologies to remove contaminants from the air. Here are a few ways these systems tackle indoor air pollution:


  • HEPA Filtration: High-Efficiency Particulate Air (HEPA) filters capture 99.97% of particles as small as 0.3 microns, including dust, pollen, and many bacteria and viruses. This level of filtration is especially helpful for families with asthma or allergies.


  • UV-C Light: Ultraviolet (UV) air purifiers use short-wave UV-C light to kill or inactivate airborne microorganisms, such as bacteria, viruses, and mold spores. This helps to reduce the overall viral and bacterial load in your home’s air.


  • Activated Carbon Filters: These filters excel at removing volatile organic compounds (VOCs) and odors, creating a fresher and healthier indoor environment.


  • Electrostatic and Ionic Filters: These air cleaners use electrically charged plates to attract and trap particles from the air, offering an extra layer of protection against airborne contaminants.


Defending Against Winter Illnesses


By running a high-quality air cleaner as part of your HVAC system, your home’s air is continuously circulated and purified. This helps:


  • Reduce Airborne Viruses and Bacteria: UV-C and HEPA filtration systems can trap and neutralize many of the pathogens that cause winter illnesses, reducing the risk of spread within your home.


  • Minimize Allergens and Asthma Triggers: Winter often means spending more time with pets, and dust and dander can accumulate quickly. Air cleaners trap these particles, providing relief for allergy and asthma sufferers.


  • Improve Sleep and General Well-being: Cleaner air means less coughing, sneezing, and throat irritation—helping you and your family get the restful sleep needed to recover from illness and stay healthy.


  • Reduce the Impact of Cooking and Cleaning Chemicals: With more time indoors, exposure to household chemicals increases. Air cleaners help reduce VOCs, making your air safer to breathe.
