Air quality in Victoria

• Long pollen season
• Garry oak & grass pollen
• Damp crawlspaces
• Fireplace & wood stove smoke
• Cruise ship & ferry exhaust
• Summer wildfire smoke

Victoria's gentle climate is the envy of the country, and the gardens that come with it are part of the city's identity. They also make for one of the longest allergy seasons in Canada. Alder and hazel can release pollen in late winter, then birch, cedar, Garry oak and the flowering trees of Fairfield and Oak Bay follow through spring, and grasses carry on into summer. For allergy sufferers, a well-fitting pleated filter in the furnace or heat pump makes a noticeable difference.

The city sits in the rain shadow of the Olympic Mountains, so it is drier than Vancouver, but winters are still damp. Many older homes in James Bay, Fernwood and Rockland sit over crawlspaces or partial basements that stay humid from November to March, and mould spores find their way into ductwork. On cold, calm evenings, smoke from fireplaces and wood stoves hangs over neighbourhoods, especially out on the Westshore and toward Sooke where wood heat is more common.

Ships add to the mix: BC Ferries from Swartz Bay, cruise ships at Ogden Point and naval vessels at Esquimalt all burn diesel, and traffic on the Trans-Canada and Pat Bay Highway funnels into the core. In recent summers, smoke from fires up-Island and on the mainland has also reached Victoria. None of this makes the city's air poor, but it does mean indoor air benefits from steady, year-round filtration rather than a filter that's changed once in a blue moon.

Victoria climate, homes & HVAC systems

Victoria has the mildest climate of any Canadian city – snow is rare, frost is brief and summers are warm and sunny without much humidity. Heating demand is modest but spread over most of the year, and an increasing number of homes have added air conditioning since recent heat waves. That steady, low-level use is exactly what heat pumps do best, which is why they have spread so quickly here.

A large share of Victoria's older houses were originally heated with oil furnaces, and many have since converted to ducted heat pumps or gas, often keeping the original ductwork and filter rack. Post-war bungalows in Saanich and Esquimalt commonly run 1-inch filters; newer homes in Langford, Colwood and Royal Bay usually have heat pumps with deeper media cabinets and an HRV; and downtown condos often rely on electric baseboards or small in-suite heat pumps. Heritage homes with unusual return grilles are a speciality of ours, since we build odd sizes to order.

Which MERV rating is right for your Victoria home?

MERV (Minimum Efficiency Reporting Value) measures how well a filter captures particles of different sizes under the ASHRAE 52.2 test standard. Higher numbers catch smaller particles. Most residential furnaces in Canada run well on MERV 8 to MERV 13 – here is how to choose:

Not sure? Read our complete MERV rating guide. If you are moving up to MERV 13 on an older furnace, a deeper 2-inch or 4-inch filter keeps airflow healthy.

Popular furnace filter sizes in Victoria

These sizes cover most Greater Victoria furnaces and heat pumps. Oil-to-heat-pump conversions and heritage homes often have unusual return openings – we stock hundreds of special sizes and make the rest to order.

How often to change your furnace filter in Victoria

Filter depth	Typical home	Pets, allergies or smoke
1-inch	Every 1–3 months	Every 30–45 days
2-inch	Every 3–4 months	Every 2 months
4-inch	Every 6–9 months	Every 4–6 months
5-inch	Every 9–12 months	Every 6 months

Victoria's heat pumps run in nearly every month of the year, so a 1-inch filter typically needs changing every two to three months, and more often during peak pollen. See the full filter changing guide.
