Indoor Air Pollution: 4 Everyday Sources That Could Be Affecting the Air in Your Home

When we think about air pollution, we often picture busy roads, vehicle emissions and smog-filled skies. But what about the air inside our homes?

While closing doors and windows may help keep some outdoor pollutants away, indoor air isn't necessarily free from pollution. Everyday activities such as cooking, cleaning and spending time with pets can introduce airborne particles into our living spaces.

Understanding where these pollutants come from is the first step towards creating a cleaner indoor environment.

1. Cooking: More Than Just Smoke and Odours

Cooking brings families together, but it can also introduce pollutants into indoor air.

Frying, grilling and high-temperature cooking can release smoke, fine particulate matter and other airborne pollutants. Even when visible smoke disappears, some particles may remain suspended in the air.

What can help?

• Use a kitchen chimney or exhaust ventilation while cooking.
• Maintain adequate ventilation whenever outdoor conditions permit.
• Consider an appropriately sized air purifier to help capture airborne particles that spread into living areas.

2. Pets: The Invisible Allergens Around Us

Pets bring companionship and happiness into our homes. However, they can also contribute to indoor airborne allergens.

Pet dander consists of tiny particles of shed skin that may become airborne or settle on furniture, carpets and bedding. Pets can also carry pollen and dust indoors on their fur.

For people sensitive to these allergens, maintaining cleaner indoor air can be particularly important.

What can help?

• Groom pets regularly and clean their bedding.
• Vacuum carpets, sofas and upholstery frequently.
• Use an air purifier with an appropriate particle filter to help capture airborne pet dander.

3. Daily Activities: Dust You May Not Even Notice

Walking across carpets, making beds, dusting furniture and cleaning the house can all stir settled particles back into the air.

Household dust can contain a mixture of fibres, skin flakes, pollen and other fine particles. Some may remain airborne long enough to be inhaled.

What can help?

• Clean surfaces using a damp cloth instead of dry dusting.
• Vacuum regularly, preferably with a HEPA-equipped vacuum cleaner.
• Keep indoor spaces clean and minimise unnecessary dust accumulation.
• Use effective air filtration to help reduce suspended particles.

4. Outdoor Air: Pollution Can Find Its Way Inside

Closing your windows doesn't necessarily mean outdoor pollution stays outside.

Fine particulate matter, including PM2.5, can enter homes through open doors, windows, ventilation systems and gaps around building structures.

During periods of poor outdoor air quality, these particles may contribute significantly to indoor pollution levels.

What can help?

• Monitor local outdoor air quality.
• Limit unnecessary outdoor-air entry during severe pollution episodes.
• Use suitable filtration to help reduce airborne particles indoors.
• Maintain ventilation appropriately, as air purifiers do not replace the need for fresh air.

How Can an Air Purifier Help?

While regular cleaning and ventilation are important, an air purifier can provide an additional layer of protection against airborne particles.

Glen Air Purifiers with H13 HEPA filtration are designed to capture fine airborne particles, including dust, pollen and certain allergens, as air passes through the filter.

Depending on the model, additional filtration and smart features can help make everyday indoor air management more convenient.

When choosing an air purifier, consider your room size, Clean Air Delivery Rate (CADR), filtration technology and filter maintenance requirements.

Cleaner Indoor Air Starts With Awareness

Indoor air pollution doesn't always come from obvious sources. Sometimes, it is part of the everyday activities that make a house a home.

Understanding these sources, improving ventilation where appropriate, cleaning regularly and using effective air filtration can all contribute to better indoor air quality.
