Get Alerts For Wildfires In Your Area
The moment a wildfire starts near you, you'll get an instant alert and simple tips to reduce your smoke exposure.
What's In The Smoke
30xSmaller than a human hair
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 FAQs
Facts About Wildfires
Over 70,000 wildfires burn in the U.S. every year.
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
Filterbuy's live map above shows active wildfires and satellite-detected smoke over Halifax, Nova Scotia, right now. Pair it with Halifax's Air Quality Health Index (AQHI). When smoke pushes the AQHI to 4 or higher, Filterbuy's advice is to switch to a MERV 13 filter, set your thermostat fan to On, run a portable HEPA air cleaner in each occupied room, and close the house up. For evacuation orders, rely on official alerts from the Province of Nova Scotia and Halifax Regional Municipality (HRM).
Why Filterbuy Built This Page
Filterbuy has manufactured air filters in the United States for over a decade and shipped them to more than two million households. We see what a filter catches during smoke and what it misses.
Key Takeaways
Canada rates smoke risk on the 1 to 10+ AQHI, which Environment and Climate Change Canada (ECCC) calculates hourly from PM2.5, the fine smoke particles 2.5 micrometres or smaller, during smoke events (Canada.ca).
Health Canada and the U.S. EPA recommend MERV 13 or higher HVAC filters during wildfire smoke (Health Canada; EPA).
Filterbuy's action line is AQHI 4 when smoke is the cause.
Only about 23% of Nova Scotia homes heat with a forced-air furnace, so for many Halifax households a portable HEPA air cleaner is the main defense (Nova Scotia Finance and Treasury Board).
How Do I Read the Halifax Wildfire and Smoke Map Today?
Filterbuy's Halifax map combines active fires from the Canadian Wildland Fire Information System (CWFIS) with satellite smoke plumes from the U.S. National Oceanic and Atmospheric Administration's (NOAA) Hazard Mapping System.
Read fire points carefully. Each point marks where a fire was reported, and a large fire's edge can sit kilometres from that dot.
Treat smoke shading as a heads-up. Satellite smoke often sits high overhead. Halifax's current AQHI shows what reaches street level, and its "AQHI by Station" view breaks readings down across HRM.
Look ahead. ECCC's FireWork forecast maps show where smoke should drift over 72 hours.
Is There a Wildfire Near Halifax, NS Right Now?
Filterbuy's status panel above shows any active wildfire near Halifax in real time. As of September 24, 2026, the season's largest Halifax County fire, the Mooseland Road wildfire, had reached about 1,447 hectares and been declared under control.
Sources: Government of Nova Scotia (BurnSafe map; July 17, 2026 wildfire season statement), Tourism Nova Scotia (Mooseland Road updates), and the North American Seasonal Fire Assessment and Outlook (issued September 14, 2026). Last updated September 24, 2026.
To report a wildfire or burning violation, call 1-800-565-2224 or 911.
What Does Halifax's AQHI Number Mean for My Home?
The Air Quality Health Index (AQHI) rates the health risk of outdoor air from 1 to 10+. When wildfire smoke pushes Halifax's AQHI to 4 or higher, Filterbuy recommends four steps: a MERV 13 filter in your HVAC system, the thermostat fan set to On, a portable HEPA air cleaner in each occupied room (bedrooms first), and a closed-up house.
Filterbuy's Halifax Smoke Action Ladder
Outdoor guidance paraphrases Environment and Climate Change Canada's AQHI health messages. Indoor steps are Filterbuy's recommendations. AQHI 4 is Filterbuy's action line when smoke is the cause; ECCC's scale does not set a threshold for changing filters.
The outdoor column paraphrases ECCC's AQHI health messages; the indoor steps are Filterbuy's. Health Canada and ECCC list children, seniors, pregnant people, outdoor workers, and anyone with a heart or lung condition as higher risk. If that includes someone in your home, follow ECCC's advice for at-risk groups and ask a health professional about a smoke plan.
Why Does Halifax Get Two Different Kinds of Wildfire Smoke?
Halifax gets smoke from local fires, which can force evacuations, and from distant fires, whose smoke can linger.
Local fire: safety comes first. The May 2023 Upper Tantallon fire burned about 969 hectares and destroyed 151 homes, and Halifax Regional Fire & Emergency's post-incident analysis found it forced 16,400 people to evacuate. Alert Ready needs LTE or 5G, so also install the NS Alert app, which works on 3G or Wi-Fi.
Long-range smoke: focus on indoor air. "We hear from households in cities that never see a flame," the Filterbuy team says. Health Canada notes that smoke can overload filters quickly. Track plumes on Filterbuy's live Canada wildfire and smoke map.
How Do I Reduce Smoke Inside My Halifax Home?
Follow ECCC air quality alerts and any Province or HRM instructions first; the steps below support that guidance. Only about 23% of Nova Scotia homes have a furnace (provincial statistics). Health Canada's MERV 13 recommendation applies where air moves through ducts. In homes without ducts, portable HEPA air cleaners are the primary defense, so start with your heating system below.
Heating shares: Nova Scotia Finance and Treasury Board, citing Statistics Canada (2021). MERV 13 guidance: Health Canada and U.S. EPA. Portable HEPA in each occupied room is Filterbuy's recommendation.
When smoke pushes the AQHI to 4 or higher, Filterbuy recommends these steps, in this order:
Put MERV 13 in your HVAC. The central system moves far more air than any portable unit; your size is on the current filter's frame. The EPA notes that most furnaces and HVAC systems can use a MERV 13 air filter without equipment problems as long as it's replaced often.
Set the thermostat fan to On. On Auto, the system filters only while heating or cooling. On keeps air moving through the filter.
Run a portable HEPA air cleaner in each occupied room. Start with bedrooms. Health Canada advises a tobacco-smoke CADR of at least two-thirds of the room's floor area, so a 300-square-foot bedroom needs a CADR of about 200. Skip ionizers and ozone generators; the EPA advises against air cleaners that produce ozone.
Close the house up. Shut windows and doors, and skip candles, frying, smoking, and vacuuming unless the vacuum has a sealed HEPA system. Oil or wood heat supplies 42% of Nova Scotia's home heating energy (provincial statistics), so test your carbon monoxide alarm before sealing up, as Health Canada advises, and leave the wood stove off.
Inspect the filter often. "Every smoke season the filters come back to us visibly darker and heavier than the ones from clean-air months," the Filterbuy team reports. EPA guidance is to replace a filter when it looks dark brown or black, which can be well before its normal interval, so keep spares on hand.
Reset afterward. Once the smoke clears, replace the loaded filter, then HEPA-vacuum and damp-wipe surfaces.
Why cleaning matters too. Filterbuy calls smoke recovery a two-clock problem: filters clear airborne particles in hours to days, but residue on walls and fabrics stays until cleaned (recovery checklist). Pleated filters capture particles; smoke odour is a gas, so for odours, look at Filterbuy's Odor Eliminator filters.
The number everyone watches is the one outside. The number that decides how your family actually feels is the dust still sitting on your baseboards three weeks later.

Supporting Statistics: What U.S. Research Shows
1. Distant smoke: 17% more asthma ER visits. When Canada's 2023 wildfire smoke crossed the U.S., asthma emergency visits ran 17% above expected on 19 smoke days. Source: Centers for Disease Control and Prevention, MMWR, August 2023
2. Wildfire PM2.5 hits harder than other PM2.5. In a NOAA-funded study, each 10 µg/m³ rise in wildfire PM2.5 raised respiratory hospitalizations 1.3% to 10%, versus 0.67% to 1.3% for other PM2.5. Source: Aguilera et al., Nature Communications, 2021, via NOAA
3. Better filtration can roughly halve indoor PM2.5. The U.S. Environmental Protection Agency reports that a high-efficiency filter with the fan always on may cut indoor PM2.5 about 50%, and a DIY box-fan cleaner cut it 56% in 90 minutes. EPA advises using only a certified box fan from 2012 or newer. Treat a DIY unit as a stopgap, and don't leave it running unattended.
