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.

Shop Filters For Smoke ProtectionLive Forest Wildfire and Smoke Map Today in Idaho (ID): Where Are Fires Burning and How Is Smoke Impacting Air Quality?
Idaho can see smoke from local forest fires, rangeland fires, and from fires in neighboring states. Valleys and basins can hold smoke longer, especially on calm or cooler mornings. That means air can look “stuck” even after fire activity slows. This guide shows how to check today’s smoke, what Idaho patterns to watch, what to do indoors, and when to change filters.
Key Takeaways
Check the AirNow Fire and Smoke Map for your Idaho location at the start of the day and again if you see haze or the wind changes.
If AQI is over 100, spend more time indoors and keep kids, older adults, and people with breathing or heart issues out of the smoke.
Close the house, run HVAC on recirculate, and use the best MERV filter your system will handle. Keep one room on a HEPA purifier.
Smoke can sit in Idaho valleys for more than one day, so look at your filter sooner than your normal schedule.
How To Check Live Smoke In Idaho Today
Open the AirNow Fire and Smoke Map.
Search by city, ZIP, or pan to your part of Idaho (e.g., Boise, Coeur d’Alene, Idaho Falls, Pocatello).
Look for:
AQI
PM2.5
active fire locations
smoke plumes moving in from other areas
If you are in southwest Idaho, also look west and south. If you are in the Panhandle, check Washington and Montana, since those fires can push smoke into Idaho.
Idaho Conditions To Watch
Morning inversions: Cooler air near the ground can hold smoke in valleys and river corridors. Air may improve after it warms and mixes.
Wind shifts with fronts or thunderstorms: A change in direction can move smoke from one part of the state to another in a few hours.
Regional fire activity: Late-summer smoke from other states can still lower Idaho air quality even if local fires are small.
Because of these factors, one map check in the morning is often not enough on active fire days.
Tips For Smoky Periods
Keep outdoor air out
Close windows and doors. Set the central system or heat pump to recirculate so it is not pulling smoky air indoors.
Run the fan
Turn the thermostat fan to “On” while smoke is present. That keeps indoor air moving across the filter.
Use a better filter if the system allows it
Daily use might be MERV 8 or MERV 11. During wildfire smoke, EPA allows using MERV 13 or higher if the system still has normal airflow and comfort. Keep a spare on hand because multi-day smoke can darken a 1-inch filter quickly.
Make one cleaner room
Choose a bedroom or main living area. Keep the door mostly closed and run a true HEPA purifier there. If you use a DIY box-fan filter, build it with a newer fan and do not leave it running unattended.
Limit indoor sources
Skip candles, incense, heavy frying, and long exhaust-fan use during smoke. Those add particles or pull smoky air inside.
When Outside And On The Road
Try to do yard work, sports, or errands when the map shows better air. If AQI is over 100, people in sensitive groups should stay inside more. If you must work outside in heavier smoke, use a well-fitting N95 or P100. Cloth masks and loose surgical masks do not filter fine wildfire smoke well. In the car, keep windows up and set the system to recirculate.
Check Your Filters After Smoke
After several smoky days, pull the HVAC filter and look at it. Replace early if:
The media looks dark or matted
The house smells smoky when the system starts
The airflow from supply vents feels weaker
Do the same for portable HEPA units or DIY box-fan filters. Idaho’s dry air plus smoke can load them faster than your usual 60–90 day schedule.

Choose Filterbuy HVAC Filters For Idaho Wildfire Season
Idaho homes often switch between heating and cooling and may run the fan longer during smoke. That works better with a snug, clean filter. Filterbuy supplies pleated HVAC filters in MERV 8, MERV 11, and MERV 13, made in the USA, in standard and custom sizes for a tight fit, with fast free U.S. shipping. Auto Delivery keeps a replacement on hand before the next fire or wind shift.
Frequently Asked Questions
How do I see today’s smoke in Idaho?
Go to the AirNow Fire and Smoke Map, type your Idaho city or ZIP, and turn on the smoke layer. That shows AQI, PM2.5, nearby fires, and where the plume is moving.
Why is it smoky if the fire is not close to me?
Smoke can drift from forest or rangeland fires elsewhere in Idaho or from nearby states. Valleys and basins can hold that smoke even after fire activity slows.
How often should I check the map?
Check in the morning, then check again if the wind shifts, storms move through, or you notice visibility dropping.
When should I stay inside more?
When AQI goes over 100, move activity indoors, especially for children, older adults, and people with asthma or heart and lung conditions.
What should I do with my HVAC?
Keep windows and doors closed and set the system to recirculate so you are not pulling smoky air in.
Which filter should I use?
Use the highest MERV your system can handle without hurting airflow. Many homes use MERV 8 or 11 daily and switch to MERV 13 during smoke.
Do I need a HEPA purifier?
It helps to have one cleaner room for sleeping or for someone who is sensitive. Run a HEPA purifier there and keep the door mostly closed.
Why did my filter get dirty fast?
Smoke plus Idaho’s dry air and dust can load a 1-inch filter in a few days. That is normal during a smoke event.
Can I run kitchen and bathroom fans?
Keep them short. Long runs can pull smoky outdoor air into the house.
Do I still follow Idaho air-quality or fire alerts?
Yes. Use the live map for current air, but follow state and local fire or health alerts for closures, burn bans, and evacuations.
