Air quality in Carleton Place
Carleton Place grew up as a mill town where the Mississippi River drops on its way from Mississippi Lake toward the Ottawa River, and the old stone mills and foundry buildings along the water are still a big part of its character. Today it is one of the fastest-growing towns in Lanark County, with Ottawa commuters filling new subdivisions on the edge of town. That growth brings construction dust, more traffic on Highway 7 and McNeely Avenue, and fresh drywall and sawdust in newly built homes.
The river and Mississippi Lake upstream keep summers humid, and the town's mature maples and the farmland around it produce heavy tree pollen in spring and ragweed by late summer. In winter, wood stoves and fireplaces in older neighbourhoods and surrounding rural properties can leave a smoky haze on still, cold evenings.
Wildfire smoke is the biggest air quality event Carleton Place now faces. During the 2023 fire season, smoke from Quebec and northern Ontario pushed Ottawa Valley air quality into the high-risk range for days, and residents were advised to stay indoors with windows closed. On days like that, a MERV 13 filter in a furnace or air handler running on continuous fan is one of the easiest ways to bring indoor particle levels down.
Carleton Place climate, homes & HVAC systems
Like the rest of the Ottawa Valley, Carleton Place has cold, snowy winters and warm, humid summers. The heating season runs from fall well into spring, and most homes rely on central air or a heat pump through July and August, so the furnace fan – and the filter – is busy almost year-round.
Older homes downtown and around the river include Victorian brick and stone houses, wartime and post-war bungalows, some still on hot-water boilers or with retrofitted forced-air systems and 1-inch filter slots. The large newer neighbourhoods on the town's north and west sides are mostly natural gas forced-air with central AC, HRVs and media cabinets, and many new builds now come with cold-climate heat pumps. Just outside town, rural homes on wells use propane, oil and wood.
MERV 11 for everyday, MERV 13 for smoke & new builds
MERV 11 is the right everyday filter for most Carleton Place homes. Choose MERV 13 during wildfire smoke events, if someone at home has asthma, or for the first few months in a brand-new house, when construction dust is still working its way out of the ducts.

- Spring: Install a fresh filter in April as maple and poplar pollen starts drifting along the river.
- Summer: Have a MERV 13 ready for smoke advisories and run the AC with windows closed when the AQHI climbs.
- Fall: Change the filter before the first furnace start and after any late-season renovation work.
- Winter: Check every month in January and February, when the furnace runs nearly non-stop.
Which MERV rating is right for your Carleton Place 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:
| Rating | What it captures | Best for |
|---|---|---|
| MERV 8 | Dust, lint, pollen, mould spores and larger particles (3–10 microns) | Budget-friendly everyday protection, rental units, new-build dust |
| MERV 11 | Everything MERV 8 does plus pet dander, fine dust and some smoke (1–3 microns) | Most family homes, pets, seasonal allergies |
| MERV 13 | Fine particles down to 0.3–1 micron, including much of the PM2.5 in wildfire smoke | Asthma, allergies, wildfire smoke, newborns and seniors |
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 Carleton Place
New subdivisions in Carleton Place usually have 5-inch or 4-inch media cabinets, while older homes near downtown generally take 1-inch filters like 16x25x1 or 16x20x1.
How often to change your furnace filter in Carleton Place
| 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 |
If you have just moved into a new build in Carleton Place, change the filter after the first month – construction dust from drywall and flooring loads filters quickly. See the full filter changing guide.

Carleton Place air filter FAQ
What MERV rating is best for Carleton Place?
MERV 11 suits most Carleton Place homes for pollen, dust and pet dander. Use MERV 13 if anyone has asthma or allergies, during wildfire smoke, or in a newly built home.
My new home in Carleton Place has a thick filter cabinet – what do I buy?
That is a 4-inch or 5-inch media filter. Read the size on the existing filter frame and order the same size in MERV 11 or MERV 13 from our 5-inch filters or 4-inch filters.
How do I protect my home from wildfire smoke?
Keep windows closed, run your furnace or air handler fan continuously and use a MERV 13 filter. Our wildfire smoke guide covers more steps, including portable HEPA units.
How often should I change the filter in an older downtown home?
Check a 1-inch filter every month in winter and replace it every 1–3 months. Older homes with plaster walls, pets or wood fireplaces usually need the shorter end of that range.
Do heat pumps need different filters?
Ducted heat pumps use the same pleated filters as furnaces. Because the fan runs for both heating and cooling, they tend to need filter changes a little more often.
Can I buy filters for a rental property in bulk?
Yes. Landlords and property managers can order case quantities and set up a business account with volume pricing.
How much does shipping to Carleton Place cost?
Orders to Carleton Place ship for a $25 flat rate, and orders of $2,500 or more ship free. Most orders arrive in 3–9 business days.
Can you make custom-size filters for my Carleton Place home or building?
Yes. Because we manufacture in Brampton, we can build non-standard and custom sizes to order – usually within about 3 weeks. Use our custom filter form or email info@canadianairfilters.com with your dimensions and MERV rating.
