1. Understand Where Dust Comes From
In the Bay Area, dust can enter your home from a mix of indoor and outdoor sources. Windy days bring in pollen, dirt, and pollution particles through open windows and doors. Indoors, dust builds up from pet dander, dead skin cells, fabric fibers, and even household items like paper. Identifying your primary sources of dust is the first step to reducing it.

2. Upgrade Your Air Filters and HVAC System
Your home’s heating and cooling system is crucial in controlling indoor air quality. Use high-efficiency particulate air (HEPA) filters or MERV 11+ rated filters in your HVAC system to trap fine dust. Change these filters every 1–3 months, depending on usage and air quality, especially during wildfire season when particulates can surge.

3. Invest in an Air Purifier
A high-quality air purifier with a HEPA filter can make a huge difference in reducing airborne dust. Place purifiers in bedrooms and living areas where people spend the most time. For best results, choose one rated for the size of the room and let it run continuously on a low setting.

4. Adopt a No-Shoes Policy Indoors
Outdoor shoes carry in dirt, pollen, pesticides, and other pollutants. Create a designated shoe-removal area near entrances and provide indoor slippers or socks for comfort. This simple habit significantly cuts down the dust and allergens tracked into your home.

5. Vacuum with a HEPA-Filter Vacuum
A regular vacuum may stir dust into the air rather than trap it. Use a vacuum cleaner with a built-in HEPA filter and strong suction power. Vacuum carpets, rugs, upholstery, and even hardwood or tile floors at least twice a week. Pay extra attention to corners and baseboards where dust loves to settle.

6. Dust Surfaces the Right Way
Feather dusters just move dust around. Instead, use microfiber cloths or electrostatic dusters that actually trap and hold particles. Always start from the top (like shelves or ceiling fans) and work your way down so you’re not dusting twice. Lightly dampen cloths to avoid kicking dust into the air.

7. Wash Bedding and Curtains Regularly
Textiles attract and hold dust like magnets. Wash sheets, pillowcases, and blankets at least once a week in hot water. Don’t forget curtains, which can gather a surprising amount of dust. If possible, opt for blinds that are easier to wipe clean.

8. Declutter and Minimize Fabric Decor
The more items you have on surfaces, the more places dust can collect. Decluttering makes cleaning easier and more effective. Avoid heavy drapes, shag rugs, and fabric-covered headboards. Instead, go for easy-to-clean materials like leather, wood, and metal where possible.

9. Keep Windows and Doors Sealed
Old or poorly sealed windows and doors let in outside dust and allergens. Inspect weather stripping and caulking annually. Installing double-paned windows or using draft stoppers can help reduce the entry of airborne particles. On high-pollen or windy days, keep windows closed and rely on air purifiers.

10. Maintain a Consistent Cleaning Routine
Keeping your Bay Area home dust-free is about consistency. Set a weekly schedule that includes dusting, vacuuming, washing linens, and wiping down surfaces. Monthly deep cleans and seasonal tasks like vent cleaning and window washing will support your efforts and maintain better air quality year-round.
