Allergy-Proof Your Home Before Pollen Season, According to Allergists

Allergy season often peaks in May in many U.S. regions, and allergists say indoor steps can reduce exposure to pollen that causes sneezing, congestion and itchy eyes. The article highlights HEPA filtration, humidity control, limiting indoor pollen entry and checking pollen forecasts as measures discussed by specialists.

Spring has arrived and allergy season is underway, with the Allergy and Asthma Network noting May is the worst month for many U.S. regions. Dr. Stephanie Kayode describes common hay fever symptoms such as sneezing, runny nose, nasal congestion and itchy or watery eyes caused when pollen provokes inflammation in the airways. Allergists consulted for the article discuss ways households can limit indoor pollen and related air pollutants before levels peak. The piece summarizes expert comments on filtration, humidity, home habits and when to involve a clinician. Key points: - HEPA air purifiers are reported to remove pollen and other airborne particles; higher airflow and an appropriately sized unit improve effectiveness and filters should be replaced as recommended. - HVAC systems using HEPA filters are advised; manufacturers' guidance and regular filter replacement (about every three months as noted) and seasonal tune-ups were emphasized. - Indoor humidity around 40%–50% and clearing debris from outdoor HVAC components were mentioned as factors that can influence indoor air quality. - Keeping windows and doors closed on high-pollen days, changing clothes after time outdoors, tying hair back or wearing a hat, and shaking out laundry dried outside were described as ways pollen can be kept from accumulating indoors. - Using cabin air recirculation in a hot car and monitoring pollen forecasts with apps were given as means to limit pollen exposure during travel and outdoor activity. - Allergists noted thunderstorms can release highly allergenic pollen fragments, a saline nasal rinse can clear inhaled pollen, and clinicians may discuss antihistamines or steroid nasal sprays when symptoms interfere with daily life. Summary: Allergists and the article present household measures—filtration, humidity control, maintenance and habits—that aim to reduce indoor pollen exposure and related airway irritation. Monitoring pollen forecasts and consulting a clinician about symptom management were described as possible next points to consider; specific individual steps or medical choices were reported as dependent on personal circumstances.
