Air quality in Clarence-Rockland
Clarence-Rockland stretches along the south shore of the Ottawa River, from the growing town of Rockland out through the farm villages of Clarence Creek, Bourget, Hammond and Cheney. The river shapes local air in a very practical way: damp mornings and spring high water keep humidity up, and the 2017 and 2019 floods left many riverside homes dealing with wet basements and mould. Even homes that stayed dry can feel musty after a wet spring.
Much of the municipality is open farmland on heavy clay soils, and dairy, hay and cash-crop fields send dust and grass pollen into the air from planting to harvest. Commuter traffic heading to Orléans and downtown Ottawa along Highway 174 and County Road 17 adds exhaust near the main road through Rockland, and wood stoves are a common sight – and smell – in the rural concessions on cold winter evenings. In recent summers, smoke from Quebec and Northern Ontario wildfires has also drifted down the Ottawa Valley.
Clarence-Rockland climate, homes & HVAC systems
Like the rest of the Ottawa area, Clarence-Rockland has long, cold winters and warm, humid summers. Open fields leave homes exposed to strong winter winds, so furnaces work hard from October to April, and central air or heat pumps carry the load in July and August.
Rockland's newer subdivisions have high-efficiency gas furnaces, HRVs and often 4- or 5-inch media filters, while older homes in the town centre date back to its lumber-mill days and frequently have smaller 1-inch filter slots. Out in the villages and farm properties, many houses heat with oil, propane or wood, or a wood-oil combination furnace, and draw water from private wells.
MERV 11 for most homes, MERV 13 after damp springs
MERV 11 captures field dust, pollen and wood smoke ash without restricting airflow. If your basement has had water or mould problems, or anyone at home has asthma, use MERV 13 and run a dehumidifier through the humid months.

- Spring: Change the filter once the river drops and the fields dry out – dust and mould spores peak together.
- Summer: Close windows on hazy wildfire days and let the AC filter the air.
- Fall: Install a fresh filter after harvest and before the furnace starts in October.
- Winter: Check monthly, and more often if you burn wood in the same house.
Which MERV rating is right for your Clarence-Rockland 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 Clarence-Rockland
These sizes cover most Clarence-Rockland furnaces. Older farmhouses and wood-oil units can have unusual filter sizes, which we build to order.
How often to change your furnace filter in Clarence-Rockland
| 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 |

Clarence-Rockland air filter FAQ
What MERV rating is best for a Clarence-Rockland home?
MERV 11 suits most homes. Choose MERV 13 for asthma, allergies, mould concerns after flooding, or wildfire smoke days.
My basement flooded in the past. Will a filter help with mould?
A pleated MERV 11 or MERV 13 filter captures mould spores circulating through the ducts, but the moisture source still needs fixing. Run a dehumidifier and change the filter more often for a few months after any water problem.
Do you ship to Bourget, Hammond and Clarence Creek?
Yes. We ship to every address in Clarence-Rockland, including the villages and rural concessions.
I heat with a wood-oil combination furnace. Which filter do I need?
Combination furnaces use standard filter slots. Read the size printed on your current filter, and stick to MERV 8 or MERV 11 to keep airflow strong on older units.
How often should I change my filter here?
Replace 1-inch filters every one to three months and deeper 4-inch filters about twice a year, with a quick look every month from November to March. See our filter changing guide.
Does wildfire smoke reach Clarence-Rockland?
Yes. Smoke from fires in Quebec and Northern Ontario has drifted over the Ottawa Valley in recent summers. Keep a spare MERV 13 filter on hand.
How much does shipping to Clarence-Rockland cost?
