Breathe Easy During Cedar Fever: Indoor Air Quality Solutions for Cedar Park Homeowners

If you live in the Hill Country, you know that January means cedar pollen. Mountain cedar (Ashe juniper) pollen counts typically skyrocket from December through February, with peak levels often occurring in January. When cold fronts bring dry, windy weather, clouds of pollen can be seen drifting from the trees. Symptoms include nasal congestion, sneezing, itchy eyes and fatigue.

HVAC strategies to reduce indoor pollen

• Keep doors and windows closed: Limiting outdoor air infiltration is the first line of defense. Use your HVAC system’s “fan on” setting to circulate and filter indoor air, especially on high-pollen days.

• Upgrade your filters: Standard fiberglass filters trap only a fraction of pollen. High‑MERV pleated filters (MERV 11–13) offer a practical middle ground, capturing most pollen grains without overloading typical residential systems. For severe allergy sufferers, consider HEPA‑style filters designed for central HVAC systems.

• UV lights for coils and ducts: Ultraviolet lights installed near your evaporator coil destroy mildew spores and bacteria in the system. While UV does not neutralize pollen itself, keeping coils clean lets your filters focus on capturing pollen.

• Replace filters regularly: Even the best filter becomes ineffective when clogged. Check your filter monthly during cedar season and replace it as needed.

Additional tips

• Shower and change clothes after spending time outdoors to remove pollen from hair and skin.

• Bathe pets frequently so they don’t track pollen indoors.

• Consider a duct cleaning if it has been several years since your last cleaning or if you have renovated recently. Built‑up dust and pollen reduce airflow and indoor air quality.
