How to reduce indoor allergens during allergy season?

Cover fabric sofas and chairs with washable allergen-proof slipcovers during allergy season. Wash them every 2-4 weeks. Alternatively, choose leather, vinyl, or tight-weave microfiber furniture that can be wiped clean.

Have HVAC ducts professionally inspected and cleaned if you notice musty odors when the system starts, visible debris blowing from vents, or suspect mold growth.

Replace wall-to-wall carpet with hard flooring (hardwood, laminate, tile, or vinyl) in bedrooms and main living areas, especially if you have moderate-to-severe allergies.

Wash all sheets, pillowcases, and blankets weekly in hot water (at least 130°F/54°C) during allergy season. Use a hot dryer cycle.

Monitor indoor humidity with a digital hygrometer ($10-15) and keep it between 30-50%. Use a dehumidifier if humidity consistently exceeds 50%, especially in basements and bedrooms.

Designate your bedroom as a pollen-free zone with these combined measures: HEPA purifier running continuously, allergen-proof bedding encasements, windows always closed, no outdoor clothing worn in the room, shower before entering, and no pets allowed.

Use a slightly damp microfiber cloth for all dusting and a damp microfiber mop for hard floors. Never dry-dust during allergy season.

Vacuum all carpets, rugs, and upholstered furniture at least twice weekly during allergy season using a vacuum with a sealed HEPA filtration system.

Replace standard fiberglass HVAC filters with MERV 11-13 pleated filters. Replace every 60-90 days during pollen season. Run the fan continuously ("fan on" not "auto") on high-pollen days.

Place a true HEPA air purifier in your bedroom and run it continuously during allergy season. Size the unit to your room (minimum CADR of 2/3 the room's square footage).
