Living in the Okanagan Valley means enjoying beautiful lakes, warm summers and four distinct seasons. Unfortunately, communities throughout the valley can also experience periods of poor outdoor air quality, particularly when wildfire smoke moves through the region.
Smoke affecting Kelowna, Vernon and surrounding Okanagan communities does not always remain outdoors. Fine particles can enter through open doors, windows, ventilation systems and small gaps in a building. Once inside, those particles may remain in the air or settle onto indoor surfaces—even after the visible smoke has cleared.
The good news is that homeowners and businesses can take practical steps to reduce smoke infiltration, improve filtration and create a more comfortable indoor environment.
Key Takeaways
- Okanagan Valley air quality can change quickly during wildfire season, so regularly check the Air Quality Health Index and local advisories.
- Fine wildfire-smoke particles can enter homes and businesses through windows, doors, ventilation systems and gaps in the building envelope.
- Keeping windows closed, using recirculation when appropriate and reducing indoor pollution sources can help protect indoor air during smoke events.
- Portable air cleaners address individual rooms, while professionally installed whole-home systems can provide broader filtration throughout a property.
- Indoor air quality solutions should be matched to the building and its HVAC system. Vernon Air Conditioning, Plumbing & Electrical Services provides professional assessments for homes and light commercial properties.
Why Okanagan Valley Air Quality Can Change So Quickly
Air quality across the Okanagan Valley can vary considerably from one community to another and from one hour to the next. Wind direction, wildfire activity, temperature and local geography can all influence where smoke travels and how long it remains.
A clear morning in Vernon does not necessarily mean conditions will remain clear throughout the day. Kelowna, Lake Country, Armstrong and other nearby communities can experience different conditions during the same smoke event.
The BC Air Quality Health Index map provides current readings from monitoring stations throughout British Columbia. Kelowna residents can also consult the City of Kelowna’s air-quality resources for information specific to the Central Okanagan.
Wildfire Smoke and Fine Particles
Wildfire smoke contains a mixture of gases and particles. One of its principal health concerns is fine particulate matter, commonly known as PM2.5.
These particles measure 2.5 micrometres or smaller. Because of their small size, they can remain suspended in the air and travel deep into the lungs when inhaled.
According to Health Canada’s wildfire-smoke guidance, exposure can irritate the eyes, nose, throat and lungs. It may also contribute to coughing, wheezing, headaches or shortness of breath.
Children, seniors, pregnant people, outdoor workers and people with existing heart or respiratory conditions may be more affected, although anyone can experience symptoms when smoke levels are elevated.
How to Check the Current Okanagan Air Quality
The Air Quality Health Index, or AQHI, communicates the health risk associated with current outdoor air quality conditions. It can help you decide whether to adjust outdoor activities or take additional precautions.
Before exercising, opening your windows or bringing outdoor air into your home, check:
- The Government of Canada Air Quality Health Index
- The BC Air Quality monitoring map
- Local weather forecasts and special air-quality statements
- Emergency information issued by provincial or local authorities
Conditions can change quickly during wildfire season, so check more than once throughout the day.
The AQHI describes outdoor conditions. It does not measure the air inside your home or business. Indoor air quality depends on how much outdoor smoke enters, the building’s ventilation and filtration, and the pollutants generated indoors.
How Wildfire Smoke Gets Inside Your Property
Closing your windows is important, but it does not make a building completely airtight. Smoke particles may still enter through:
- Open doors and windows
- Gaps around exterior doors and window frames
- Bathroom and kitchen exhaust systems
- Fresh-air intakes
- Attached garages
- Damaged or poorly sealed ductwork
- Normal air leakage through the building envelope
People and pets can also carry settled particles indoors on clothing, shoes and fur.
The amount of smoke entering a building will vary. Newer, tightly sealed properties may behave differently from older homes, while light commercial buildings may have mechanical ventilation systems that continuously bring in outdoor air.
How to Improve Indoor Air During Okanagan Wildfire Smoke
Keep Windows and Exterior Doors Closed
When outdoor air quality is poor, keep windows and exterior doors closed as much as practical. Check weather stripping and seals around frequently used entrances, but do not block required ventilation or combustion-air openings.
Wildfire smoke and extreme heat can occur simultaneously. Health Canada advises prioritizing keeping cool during extreme heat. If the property becomes dangerously warm, seek a cooler location with cleaner air rather than remaining inside an overheated building.
Use Recirculation When Appropriate
A recirculation setting reduces the amount of outdoor air brought into the building. If your HVAC or ventilation system offers this setting, it may be helpful while outdoor smoke levels are elevated.
System designs differ, especially in light commercial properties. Do not disable required ventilation or change unfamiliar controls without professional guidance.
Once outdoor air improves, bringing in cleaner outdoor air can help remove pollutants that have accumulated inside.
Reduce Sources of Indoor Pollution
During a smoke event, avoid adding unnecessary particles and gases to the indoor air. Where possible:
- Avoid smoking or vaping indoors
- Limit the use of candles and incense
- Avoid using unvented combustion equipment
- Reduce frying and other high-smoke cooking methods
- Wet-mop hard surfaces instead of stirring up settled dust
- Use a vacuum equipped with a HEPA filter
- Limit heavily fragranced sprays and high-VOC products
Never operate a generator, barbecue or other fuel-burning outdoor appliance inside a home, garage or enclosed area.
Inspect Your HVAC Filter
A heavily loaded filter can restrict airflow and may no longer perform effectively. Inspect it during prolonged smoke events and replace it according to the equipment manufacturer’s instructions.
A higher-efficiency filter is not automatically suitable for every furnace or air handler. Installing a filter that creates too much resistance can reduce airflow and affect system performance.

Portable Air Cleaners Versus Whole-Home Air Quality Systems
Portable and whole-home equipment can both improve indoor air quality, but they serve different purposes.
Portable Air Cleaners
A portable air cleaner is designed primarily for an individual room or defined space. It can be helpful in a bedroom, nursery, home office or another area where people spend considerable time.
When choosing a portable unit, look for:
- Certification from a recognized testing organization
- A HEPA filter intended to capture fine particles
- A clean air delivery rate suitable for the room
- Replacement filters that are readily available
- A noise level appropriate for the intended location
Health Canada recommends selecting a unit based on room size and its clean air delivery rate. Its portable air-cleaner guidance explains how to compare equipment.
Avoid ozone generators marketed as residential air cleaners. Health Canada advises against using ozone generators in homes because the ozone they produce may harm human health.
Whole-Home Indoor Air Quality Equipment
Whole-home equipment works with a central HVAC system to treat air as it circulates through the building. Depending on the property, available options may help address particles, odours, ventilation or other specific concerns.
A whole-home approach may be appropriate when:
- Smoke or dust affects several rooms
- Occupants want filtration throughout the property
- Portable units are impractical for the space
- The existing HVAC filter is not meeting the property’s needs
- A home feels stale or poorly ventilated
- A light commercial property requires a more integrated solution
Equipment must be properly matched to the HVAC system. Airflow, duct configuration, available space, electrical requirements and maintenance all influence which solution will perform as intended.

Indoor Air Quality Concerns Beyond Wildfire Smoke
Wildfire smoke may be the most visible Okanagan air-quality concern, but it is not the only factor affecting the air inside a building.
Dust, Pollen and Pet Dander
Particles from outside, household dust and pet dander can circulate through occupied spaces. The right filtration strategy may reduce airborne particles, but equipment selection must account for the airflow requirements of the HVAC system.
Excess or Insufficient Humidity
Humidity can affect comfort and building conditions. Excess moisture may contribute to condensation and conditions that support mould growth, while very dry air may cause discomfort during winter.
Persistent condensation, water damage or visible mould should be investigated at the source. Air-cleaning equipment is not a substitute for correcting leaks or moisture problems.
Stale Air and Ventilation Problems
Cooking, cleaning products, building materials and everyday activities can introduce odours and gases indoors. In tightly sealed buildings, these contaminants may accumulate when ventilation is insufficient.
Filtration and ventilation perform different jobs. Particle filters capture certain airborne material, while ventilation replaces indoor air with outdoor air when outdoor conditions are suitable.
Carbon Monoxide and Radon
Carbon monoxide and radon require dedicated safety measures. A standard air filter or portable particle cleaner should not be relied on to detect or control either gas.
Properties with fuel-burning appliances should have properly installed and maintained carbon-monoxide alarms. Radon can only be identified through appropriate testing. Consult the Government of British Columbia’s radon information for provincial guidance.
Signs Your Indoor Air Quality May Need Attention
Indoor air-quality problems are not always visible. Consider having your property assessed if you notice:
- Wildfire-smoke odours that persist indoors
- Excessive dust returning shortly after cleaning
- Filters becoming dirty unusually quickly
- Stale or stuffy rooms
- Uneven humidity or frequent condensation
- Persistent unexplained odours
- Visible moisture around vents or equipment
- Poor airflow from supply registers
- Certain rooms feeling noticeably different from others
- Indoor irritation that seems to improve after leaving the building
These signs do not identify a specific contaminant or medical condition. They indicate that filtration, ventilation, humidity, equipment condition or another building factor may require closer examination.
If anyone experiences severe breathing difficulty, chest pain or another medical emergency, seek immediate medical assistance.

What to Do After the Wildfire Smoke Clears
Particles can remain indoors after outdoor air quality improves. Once local advisories indicate that conditions are better:
- Open windows and doors when it is safe to do so
- Return ventilation equipment to its normal operating mode
- Inspect HVAC and portable air-cleaner filters
- Replace filters when required
- Wet-mop hard floors and wipe settled dust from surfaces
- Vacuum carpets using a HEPA-equipped vacuum
- Test smoke and carbon-monoxide alarms
- Continue monitoring the AQHI in case conditions change
Do not replace filters while smoke is still entering the building unless the existing filter is excessively loaded or the manufacturer recommends replacement. Keep spare filters available during wildfire season whenever possible.
Frequently Asked Questions About Okanagan Air Quality
Does air conditioning remove wildfire smoke?
Air conditioning helps keep a building cool, and some systems can operate in recirculation mode. However, an air conditioner is not automatically an air purifier. Smoke-particle removal depends on the filter, system configuration, airflow and how much outdoor air enters the building.
Should I install a MERV 13 filter?
Health Canada identifies MERV 13 or higher filtration as effective for capturing more fine particulate matter, but not every residential HVAC system can accommodate the additional airflow resistance. Use the highest-quality filter your system can safely handle according to manufacturer guidance or a qualified HVAC professional.
Will a particle filter remove the smell of wildfire smoke?
Particle filtration and odour control are different. A particle filter may capture fine material without removing all smoke odours or gases. Some systems incorporate activated carbon or another adsorbent material for odour reduction.
Should I leave my HVAC fan running during a smoke event?
Continuous circulation may move more air through the filter, but it can also increase energy use and place additional demand on a loaded or restrictive filter. The appropriate setting depends on the system and filtration equipment. Consult an HVAC professional if you are unsure.
Do I need duct cleaning to improve indoor air quality?
Duct cleaning is not a universal solution for every indoor air-quality concern. An inspection may be appropriate when there is visible contamination, construction debris, pest activity or material entering the occupied space. Filtration, moisture control, ventilation and equipment maintenance may be more relevant in other situations.
Can one indoor air quality product solve every problem?
No. Fine particles, odours, humidity, gases and ventilation problems require different approaches. The best solution begins by identifying the concern and matching the equipment to both the property and its HVAC system.
