Improving Indoor Air Quality: Insights from HVAC Expert Ken Hansen

Indoor air quality often becomes a primary concern for homeowners only after they start experiencing symptoms such as sneezing, coughing, or itchy eyes. In the Pacific Northwest, where the climate is notably damp, addressing air quality issues can be particularly challenging. Mold, mildew, and dust mites thrive in such conditions, while seasonal pollen and wildfire smoke are additional nuisances that permeate indoor spaces, making it difficult to breathe comfortably.

In the latest feature on HelloNation, HVAC professional Ken Hansen from Twin City Service in Kelso, WA, provides homeowners with practical guidance on how to enhance their indoor air environment and minimize allergens effectively throughout the year.

Start with the HVAC Filter

Hansen emphasizes that a primary step in improving indoor air quality is upgrading the HVAC filter. Standard filters in heating and cooling systems are mainly designed to protect the system itself rather than the home's occupants. For those concerned about allergies, Hansen recommends a filter with a Minimum Efficiency Reporting Value (MERV) rating between 11 and 13. This rating strikes a balance by effectively capturing a range of allergens like dust, pollen, pet dander, and mold spores without significantly impeding airflow. If the HVAC system can accommodate them, even higher-rated filters can be beneficial.

Whole-House Air Purifiers

For enhanced protection, a whole-house air purifier can be a game-changer. These systems can capture even smaller particles, including bacteria and specific viruses. HEPA filters, capable of trapping particles down to a fraction of a micron, combined with activated carbon to eliminate odors and chemical vapors, significantly improve air quality. Additionally, UV-C light can neutralize harmful microorganisms before they disperse in the home—a feature that proves crucial during wildfire seasons when outside air quality plummets.

Control Indoor Humidity

Another pivotal factor in managing indoor allergens is controlling humidity levels. Hansen advises maintaining indoor humidity between 30 and 50 percent to deter mold growth and dust mites while ensuring comfort. During winter months, homeowners might need to introduce humidity into the air using a whole-house humidifier, whereas, in spring and summer, dehumidifiers or air conditioners can help eliminate excess moisture. This careful balance not only enhances comfort but also safeguards wooden floors, furniture, and structural elements from warping and mold damage.

Regular HVAC Maintenance

Routine maintenance of HVAC systems is essential for keeping the air clean. Untended heating or cooling systems can become reservoirs for dust and moisture, which fosters mold growth. Regular inspections are vital—Hansen suggests checking that filters are correctly installed, ensuring coils and drain pans are clean, and verifying that airflow isn’t obstructed.

Improve Air Circulation

Fresh air circulation also plays a critical role in achieving better air quality. In homes that are well-sealed, accumulated stale air may result in poor ventilation. Systems like energy recovery ventilators can introduce fresh outdoor air while limiting energy loss. Additionally, on days with favorable outdoor air quality and low pollen counts, briefly opening windows can renew indoor air significantly.

For households dealing with severe allergy issues, Hansen recommends establishing an “allergy-safe” zone—such as a dedicated bedroom equipped with its own air purifier, allergen-proof bedding, and strict cleaning routines. This space becomes a sanctuary for family members needing respite from allergens throughout the day.

Daily Cleaning Habits

Adopting daily cleaning habits can significantly reduce indoor allergens. Using a vacuum equipped with a HEPA filter, washing bedding in hot water weekly, and maintaining well-groomed pets are all effective strategies. Furthermore, it’s wise to avoid scented candles, aerosol sprays, and aggressive cleaning chemicals, as these can introduce volatile organic compounds that irritate the respiratory system.

While no single method will eliminate all allergens from a home entirely, Hansen emphasizes that a holistic approach—employing filtration, humidity regulation, ventilation, and consistent cleaning—can substantially enhance indoor air quality. Amidst the damp and pollen-heavy environment of the Pacific Northwest, a persistent strategy for managing air quality leads to healthier living conditions and prolonged comfort for occupants.
