Indoor Air Quality Month: 7 Things Every Home and Office Should Do This October

October is Indoor Air Quality Month. A timely reminder that clean floors and polished surfaces are only part of a healthy indoor environment. The air inside homes and offices can collect dust, allergens, moisture, odors, and chemical vapors, especially when ventilation is limited.

The Global Commission on Healthy Indoor Air, led by the International WELL Building Institute, brings together more than 200 experts from over 40 countries to advance healthier indoor environments. Its framework emphasizes practical action, better building standards, education, and ongoing monitoring.

You do not need to overhaul your entire home or facility this October. Start with these seven actions. They are simple enough for a homeowner to use and structured enough for a facility manager to add to an office cleaning plan.

1. Vacuum with HEPA filtration, and slow down

Use a vacuum with a genuine HEPA filter on carpets, rugs, upholstered furniture, stairs, and fabric office partitions. Move slowly, especially in high-traffic areas, so the machine has time to collect fine particles instead of merely pushing them around.

HEPA-filtered equipment can help capture fine dust, pollen, pet dander, and other particles that ordinary vacuuming may recirculate. For better results:

• Vacuum entryways and hallways more frequently than low-traffic rooms.
• Use the appropriate attachment for upholstery, mattresses, and fabric chairs.
• Empty or replace the vacuum bag and filters according to the manufacturer’s instructions.
• Keep sensitive occupants away from the area while heavy vacuuming is underway.
• Follow with damp microfiber cleaning rather than dry sweeping.

Do not assume that a vacuum labeled “high efficiency” automatically performs like a certified HEPA unit. Check the equipment specifications. In commercial spaces, also inspect hoses, seals, and filter condition because damaged equipment can release collected dust back into the air.

2. Dust with damp microfiber cloths

Dry dusting often moves particles from one surface to another, and sends some of them into the breathing zone. Instead, use a slightly damp microfiber cloth to capture dust from shelves, window sills, desks, electronics, baseboards, and other horizontal surfaces.

Work from high to low:

1. Ceiling fans and high shelves
2. Light fixtures and upper ledges
3. Desks, tables, and counters
4. Baseboards and lower furniture
5. Floors

This order matters. Dust naturally falls downward, so cleaning floors first means you may have to do them again. We recommend using separate, color-coded cloths for restrooms, kitchens, offices, and general surfaces. That simple system helps prevent cross-contamination.

Avoid saturating electronics, wood, or porous materials. Spray the cloth, not the surface, when appropriate, and always follow the product label. Never mix cleaning products. Combining chemicals can create harmful vapors even when each product seems harmless on its own.

3. Improve ventilation and fresh-air exchange

Open windows or doors when outdoor conditions and air quality make it safe to do so. In homes, run kitchen and bathroom exhaust fans during moisture-producing activities and for a short period afterward. In offices, keep supply and return vents unobstructed and report unusual odors, condensation, or stuffy areas to building management.

Ventilation helps dilute indoor pollutants, moisture, and odors. It can also reduce the concentration of vapors released during cleaning, painting, cooking, or renovation. However, opening a window is not always the right answer. Keep windows closed during wildfire smoke, poor outdoor air quality, extreme humidity, or other unsafe conditions.

Facility managers should review:

• Whether outdoor-air intakes are blocked or located near vehicle exhaust
• Whether restroom and kitchen exhaust fans vent outdoors
• Whether meeting rooms become stuffy when occupancy rises
• Whether ventilation complaints are documented and investigated
• Whether HVAC maintenance is performed on schedule

Cleaning teams cannot correct every IAQ problem. If occupants experience persistent headaches, respiratory irritation, or symptoms that improve after leaving the building, involve qualified building engineers, occupational health professionals, or medical providers.

4. Choose low-VOC, fragrance-free cleaning products

A space should smell clean, not smell strongly of perfume. Fragrance can mask odors without removing their source, and some products release volatile organic compounds, commonly called VOCs, into indoor air.

For routine cleaning, select products that are:

• Low-odor or fragrance-free
• Clearly labeled with safe-use instructions
• Appropriate for the surface being cleaned
• Vetted through recognized environmental standards
• Used at the recommended dilution

At AMAH, we use environmentally responsible products, techniques, and equipment, including products vetted to Green Seal and EcoLogo standards. Our approach is also grounded in the health-focused principles of the WELL Building Standards.

“Natural” does not automatically mean safe in every situation. Essential oils, concentrated acids, solvents, and even homemade mixtures can irritate the eyes, skin, or respiratory system. Use ventilation, gloves, and other protective equipment when the label requires them. Store products in their original containers and keep them away from children, pets, food, and occupied work areas.

5. Control dust and moisture at the source

The best way to reduce indoor pollutants is often to stop them from entering or accumulating in the first place. Place durable entryway mats at exterior doors and clean them regularly. Encourage household members, employees, and visitors to wipe their feet or remove outdoor footwear where practical.

Source control also includes moisture management:

• Repair plumbing and roof leaks promptly.
• Dry wet materials as quickly as possible.
• Use exhaust fans in kitchens and bathrooms.
• Keep indoor humidity at a moderate level.
• Inspect areas around windows, sinks, HVAC equipment, and exterior walls.
• Do not cover up persistent mold or water damage with paint.

Small areas of surface mildew may sometimes be addressed with appropriate cleaning, but extensive mold growth, hidden moisture, sewage contamination, or water-damaged porous materials require qualified remediation. Do not disturb suspected asbestos or lead-based paint while cleaning or renovating. Bring in trained professionals when a hazard may be present.

6. Maintain HVAC filters and air-cleaning equipment

Check HVAC filters this October and record the replacement date. Replace them according to the equipment manufacturer’s instructions, household conditions, and building needs. Homes with pets, renovations, or high dust loads may need more frequent attention.

In offices, facility teams should maintain a filter schedule rather than replacing filters only after occupants complain. Keep filter access panels closed and inspect for gaps or bypasses that allow air to flow around the filter.

Portable air cleaners can be useful in bedrooms, living areas, conference rooms, and other occupied spaces. Choose a unit sized for the room and maintain it as directed. A filter that is clogged or overdue for replacement cannot perform properly.

Do not install a higher-efficiency filter without confirming that the HVAC system can handle it. An overly restrictive filter may reduce airflow and put stress on the equipment. When in doubt, ask a qualified HVAC professional.

7. Schedule a deep cleaning for overlooked dust reservoirs

Routine cleaning handles visible soil. A seasonal deep cleaning reaches the places that quietly collect dust and allergens:

• Air-return grilles and vent covers
• Ceiling fans and light fixtures
• Baseboards and door frames
• Window tracks and sills
• Upholstery and fabric chairs
• Under beds, sofas, and office furniture
• High shelves and cabinet tops
• Stair edges and carpet borders
• Behind appliances and equipment
• Entryway mats and storage areas

In post-construction or pre-occupancy spaces, fine dust deserves special attention. Standard sweeping may redistribute particles, so professional crews should use suitable dust-control equipment, HEPA-filtered vacuums, damp methods, and a room-by-room sequence.

For a home, schedule a deep clean before hosting guests, after renovations, or when dust seems to return immediately after routine cleaning. For an office, coordinate cleaning after construction, furniture moves, seasonal changes, or extended periods of reduced occupancy.

Put healthier indoor air into practice this October

Healthy indoor air is not created by one scented spray, one open window, or one annual cleaning. It comes from combining source control, ventilation, filtration, moisture management, safer products, and consistent cleaning practices.
