How to Maintain a Clean Home During Texas Pollen Season

Understanding North Houston Pollen Season

Pollen season in our area is not one event — it is a rolling sequence of tree, grass, and weed pollens that starts in February and does not fully subside until June. Cedar and juniper start the season in January and February. Oak and pine peak in March and April, producing the visible yellow dust that coats cars, sidewalks, and everything outdoors. Grass pollen takes over from May through June.

The sheer volume is what makes Houston different. A single oak tree can release billions of pollen grains in a season. With the dense tree canopy across Montgomery and Harris counties, pollen counts routinely exceed 1,500 grains per cubic meter — well above the "very high" threshold of 1,000.

Keeping Pollen Out of Your Home

• Keep windows and doors closed during peak pollen hours — typically 5 AM to 10 AM
• Use the recirculate setting on your car AC during commutes to avoid bringing car-cabin pollen into the garage
• Create a shoe-off policy at every entry — shoes track in significant pollen
• Designate a landing zone near the door for outerwear that has been outside
• Wipe pets with a damp cloth every time they come inside — fur is a pollen magnet
• Brush off jackets and bags before entering

Daily Cleaning Habits During Pollen Season

Every Day

• Wipe all horizontal hard surfaces with a damp microfiber cloth — counters, tables, nightstands, window sills
• Vacuum high-traffic areas with a HEPA-filtered vacuum
• Damp-mop hard floors in entryways and hallways
• Shake out or wipe doormats

Every Other Day

• Vacuum all carpeted areas thoroughly
• Wipe window sills and ledges where pollen accumulates between blind slats
• Clean bathroom surfaces — pollen settles everywhere, including on damp bathroom counters

Weekly

• Wash bedding in hot water — pollen transfers from hair and skin to pillowcases nightly
• Vacuum couches and upholstered furniture
• Wash doormats in the washing machine
• Clean window screens with a hose — screens trap pollen and restrict the little airflow you might want on nice days

HVAC Strategies for Pollen Season

• Use MERV 13 filters and change them every 30 days from February through June
• Run the HVAC fan on continuous mode during high-pollen days — this filters air even when the system is not actively heating or cooling
• Consider adding a standalone HEPA air purifier in bedrooms and main living areas
• Have ducts professionally cleaned if they have not been done in three or more years

When Cleaning Alone Is Not Enough

Maintaining a clean home during pollen season is genuinely more work than any other time of year. The daily wiping, vacuuming, and mopping can feel relentless. Many North Houston families increase their cleaning frequency during pollen season — from bi-weekly to weekly professional service — so they can keep their home comfortable without sacrificing every evening and weekend to cleaning duties.
