Fine enough to reach deep into the lungs. A MERV 13 is built to capture it.
How Far It Travels
It Doesn't Stay Local
Smoke rides the wind far downwind — you can get smoky air with no fire nearby.
What To Do During A Smoke Event
Simple steps to reduce indoor exposure.
- Stay In, Close UpShut windows and doors to keep smoke out.
- Set Fan To "On"Keeps air cycling through your filter, not just when heating or cooling.
- Recirculate AirSwitch off fresh-air intake so you're not pulling smoke in.
- Run A MERV 13Built to capture the fine PM2.5 in smoke.
- Add A PurifierExtra filtration for the room you use most.
- Wear an N95 if OutsideFits snug to block fine particles — a cloth mask won't.
The Best Air Filter For Wildfire Smoke
During smoke events, the EPA recommends upgrading to a MERV 13 filter — or the highest-rated filter your system can handle — to help reduce the fine particles smoke brings indoors. MERV 13 is the level most home HVAC systems can run while still capturing PM2.5, the fine particulate that makes up the bulk of wildfire smoke.


- Captures PM2.5 particles
- Blocks ash, soot, and smoke odor
- Keeps your indoor air safe—even when the outdoor air is dangerous
- Meets the EPA's recommended rating for filtering fine wildfire smoke particles.

Wildfire smoke can travel 1,000+ miles, affecting states that aren't even near the blaze.
Exposure to wildfire smoke can worsen asthma, trigger heart issues, and lead to ER visits.
Indoor air can hold more fine particles during wildfire events unless it's properly filtered.
The EPA advises using MERV 13 filters or portable HEPA air cleaners during wildfire smoke events.

TL;DR
The live map above shows wildfires and smoke near Mirabel, QC today; confirm it with the SOPFEU interactive map, Environment Canada's FireWork smoke forecast and Quebec's real-time Air Quality Index (IQA). When the IQA reads poor or a smog warning is issued, follow official advice, close the house up, and filter the air. With a furnace, that means a Filterbuy MERV 13 air filter with the fan set to On, plus a portable HEPA air cleaner in each occupied room. Without ducts, portable HEPA air cleaners are your main defence.
Key Takeaways
SOPFEU’s interactive map is the official source for active forest fires in Quebec.
Smoke in Mirabel usually drifts in from distant fires.
About 65% of Quebec homes have no ducts, so portable HEPA air cleaners do the main work.
Filterbuy’s action line (IQA poor, a smog warning or AirNow AQI 100): MERV 13, fan On, and a HEPA air cleaner in each occupied room.
Our view: go into furnace season with a fresh filter, not the one that sat through summer smoke.
Is There a Wildfire or Smoke Near Mirabel, QC Today?
Check the live map at the top of this page, then the official tools below or SOPFEU's Laurentides page. As of mid-October 2026, SOPFEU has paused its fire danger index until spring. Forest fires inside Mirabel are rare, since about 87% of the city is farmland (Ville de Mirabel, 2022), but smoke can still drift in.

Why Mirabel Gets Wildfire Smoke From Distant Fires
Winds carry smoke south from fires in northern Quebec, Abitibi and northern Ontario, and fine smoke particles (PM2.5) can hang over the St. Lawrence lowlands for days.
On 25 June 2023, smoke from northern Quebec gave Montréal the worst air quality of any major city in the world, according to IQAir, as The Globe and Mail reported.
How to Read Mirabel's Fire and Smoke Map
At Filterbuy, we read the maps in order: fires, then where the smoke is heading, then your local IQA. Wind direction matters more than distance, so a fire 300 km upwind can affect Mirabel more than a closer one downwind.
Table B: How to Read Mirabel's Fire and Smoke Map
IQA categories are set by Quebec's Ministry of the Environment. AQI 100 is Filterbuy's action line, not an official category.
What to Do When Smoke Reaches Mirabel
Start with official guidance: Environment Canada smog warnings, Santé Québec and Health Canada advice, and the AirNow Fire and Smoke Map. If officials tell you to stay indoors, relocate or evacuate, follow them first.
Filterbuy’s action line is when the IQA reads poor (51+), a smog warning is issued, or AirNow shows AQI 100 or higher. That’s our house rule, not an official threshold. Then take these four steps:
Fit a MERV 13 filter in your furnace or central air, sized like any filter swap (how to upgrade).
Set the thermostat fan to On, not Auto, so the system filters continuously. Use recirculate if it has a fresh-air intake.
Run a portable HEPA air cleaner in each occupied room, bedrooms first (air cleaner vs. HVAC filter).
Close the house up. Keep windows and doors shut, limit exhaust fans, and skip smoking, candles, frying and vacuuming without a HEPA vacuum.
The two layers do different jobs: MERV 13 treats the whole house, while a portable HEPA unit cleans one room harder. HEPA belongs in the portable unit, never the furnace slot. As smoke lingers, check the filter often and keep replacements on hand. People with heart or lung conditions should follow their health care provider and Health Canada.
Which Advice Fits Your Mirabel Home? Start With Your Heating System
Most Quebec homes don't have a furnace. In 2021, 58% of Quebec households heated with electric baseboards and 7% with electric radiant heat (Statistics Canada). Without ducts, portable HEPA air cleaners are your main defence. Air exchangers, also common here, bring outdoor air inside; Santé Québec advises turning them off or to recirculation during smoke.
Table C: Which Smoke Advice Fits Your Home?
Sources: Statistics Canada and Santé Québec. Portable air cleaner advice is Filterbuy's recommendation. Follow your equipment manufacturer's instructions.
Size a portable air cleaner by its smoke CADR (clean air delivery rate). The EPA advises at least two-thirds of the room's square footage, so a 300 sq ft bedroom needs about 200. Skip ionizers and other ozone-producing cleaners, which EPA doesn't recommend for smoke.
A box-fan cleaner with a 20x20x1 MERV 13 filter is a stopgap, not a replacement for a certified air cleaner. Use a certified fan made in 2012 or later, and never leave it running unattended or while you sleep (Health Canada). We also carry purifier filters.
What Filterbuy Has Learned Making Filters for Smoke Season
After more than a decade of smoke seasons, our team sees one pattern: the homes ready for smoke fit a clean MERV 13 before the haze arrives. Airflow is a poor warning sign, because smoke weakens the electrostatic charge a filter uses to catch fine particles. Use the Filterbuy Three-Signal Rule instead: look, smell, and count days in smoke.
When Filterbuy prints 90 days on a MERV 13 box, that number describes how the filter behaves against household dust.

1. Canadian wildfire smoke drove an 81.9% one-day jump in asthma emergency visits. On 7 June 2023, asthma emergency visits in New York State outside New York City rose 81.9% compared with the five days before. Source: CDC, Morbidity and Mortality Weekly Report.

3. Filter thickness and freshness change the results. In EPA smoke tests, a box fan with one MERV 13 filter delivered 111 cubic feet per minute of clean air, and a four-filter design delivered 401. Dirty filters made both almost useless. Source: U.S. EPA Office of Research and Development.
Smoke Season to Furnace Season: A Filter Plan for Mirabel Homes
Mid-October is a handoff we watch for. If your filter sat through any smoky days, Filterbuy recommends replacing it before heating season, even if it only looks lightly grey. Outside smoke events, a 1-inch filter changed every 60–90 days from October to April works out to three filters. Add one or two spares by April, because SOPFEU notes that most Quebec vegetation fires happen in spring.

Fitting MERV 13 is a normal swap: confirm your size and a snug fit.

In 2026, Mirabel was among the territories under Quebec's ban on open fires in or near forests. Mirabel's by-law No. 662 also applies; SOPFEU attributes 80% of Quebec wildfires to human carelessness.
