New Yorkers are grappling with the impact of Canadian wildfire smoke, leading to a red-tinged sky and health concerns. Despite a recent heatwave, air conditioning usage remains high. Experts recommend keeping windows and doors closed and using AC to maintain indoor air quality, rather than allowing outside air in, which could worsen health risks.
To ensure clean air, HVAC professionals suggest regularly maintaining air conditioned units—cleaning filters every 4 to 6 weeks and replacing them as needed. For window units, sealing gaps with foam can enhance insulation and minimize outside air intrusion. Central air systems may struggle to filter wildfire smoke effectively, prompting calls for better maintenance.
Portable air conditioners with a single hose should be used sparingly, as they can pull in more smoke. It’s important to note that while air conditioners cool spaces, they do not purify air—air purifiers are necessary for that function. The EPA advises placing air purifiers in high-traffic areas and running them at maximum speed.
In addition, individuals should avoid activities that worsen indoor air quality, such as smoking, cooking with gas, or using aerosol products. Lastly, taking breaks from strenuous activities can help reduce exposure to pollutants.
