The moment a wildfire starts near you, you'll get an instant alert and simple tips to reduce your smoke exposure.
30xSmaller than a human hair
Fine enough to reach deep into the lungs. A MERV 13 is built to capture it.
It Doesn't Stay Local
Smoke rides the wind far downwind — you can get smoky air with no fire nearby.
Simple steps to reduce indoor exposure.
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.
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.

Babylon sits inside New York State's Long Island air quality region, so every Nassau and Suffolk advisory applies here. The AirNow Fire and Smoke Map is the fastest way to see what is in the air. Two unrelated hazards drive smoke here: Pine Barrens brush fires each spring and Canadian smoke each summer. A MERV 13 filter on a continuous fan is the strongest whole-home answer, and where there is no ductwork, a sealed clean room takes its place.
To check live wildfire and smoke conditions in Babylon today, open the AirNow Fire and Smoke Map and search ZIP code 11702. The map overlays modeled smoke plumes on live particle readings from nearby monitors, with satellite fire detections marked. Because New York State forecasts Babylon within its Long Island region, any Suffolk County advisory covers you.
Babylon has two smoke seasons rather than one. Local brush fire risk peaks in late winter and early spring, while Canadian smoke peaks in summer.
Part of the Edgewood Oak Brush Plains Preserve, Long Island's largest pitch pine and scrub oak remnant, sits inside the Town of Babylon.
New York bans residential brush burning from March 16 through May 14, the window when debris fires cause most spring wildfires in the state.
The EPA recommends a MERV 13 or higher filter during smoke events for systems that can take one, with the fan set to On rather than Auto.
Three free tools cover live conditions in Babylon. The AirNow Fire and Smoke Map reports fine particle levels alongside fire detections. The National Weather Service fire weather outlook publishes red flag warnings for local ignition risk, and New York State issues a next-day AQI forecast by region.
The plume overlay settles the question you have when the sky over the Great South Bay turns milky. Trust the plume only when a nearby particle reading agrees, since clean numbers under a plume usually mean the smoke is still aloft.
Monitors are sparse on Long Island, so AirNow closes the gap with corrected sensor data, which is why a Babylon reading can differ from a county average. The Filterbuy live air quality index and wildfire smoke map add a filter recommendation, and our guide to reading a wildfire smoke map covers what each color band means indoors.

The Air Quality Index compresses pollutant concentrations onto a single 0 to 500 scale. New York State issues an advisory when ozone or fine particles are forecast above 100. For Babylon, that is the signal to close the windows and put the fan on recirculate.
Fine particulate matter, or PM2.5, matters most in a smoke event. These particles are small enough to reach deep into the lungs and, according to public health agencies, the bloodstream. This is the size class Filterbuy builds pleated media to catch, and why a fiberglass panel is useless in smoke. Fiberglass protects the equipment, not the people.
Ozone is the other trigger, and on Long Island it dominates mid-summer. New York State issued one for the Long Island and New York City Metro regions on August 7, 2026.
Category thresholds follow the U.S. Environmental Protection Agency scale. New York State issues an Air Quality Health Advisory when the regional forecast exceeds 100.
Most smoke coverage for Long Island treats wildfire as a single season. Filterbuy does not, because Babylon faces two unrelated hazards on separate calendars. Brush fires in the Pine Barrens threaten late winter and early spring, while Canadian smoke arrives in summer as upper-air transport. Both call for the same indoor response but announce themselves very differently.
Compiled from New York State advisory records for 2025 and 2026 and Central Pine Barrens wildfire management guidance.
Protecting indoor air follows a fixed order: seal the envelope, stop adding indoor sources, upgrade filtration, run the system. EPA guidance on wildfires and indoor air quality and CDC wildfire safety guidance agree: a MERV 13 or higher filter, fan set to On instead of Auto.
Close windows and doors when an advisory is issued, or the plume reaches Suffolk County.
Switch the system to recirculate, or close the outdoor air intake damper.
Install a MERV 13 filter sized to your return; airflow arrow toward the blower.
Move the thermostat fan from Auto to On so it filters continuously, not only while heating or cooling.
Stop adding indoor particles: no candles, incense, frying, wood fires, or vacuuming without a sealed HEPA unit.
Turn off bathroom and kitchen exhaust fans, which pull replacement air in through every gap.
Set up one clean room, usually a bedroom, with a portable air cleaner sized for it.
Inspect the filter every two weeks in heavy smoke and replace it once it looks loaded.
Most smoke advice assumes a furnace with a return grille, and plenty of Babylon homes have none. Older South Shore housing pairs baseboard heat with window air conditioners, which changes every step above. A window unit pulls outdoor air into the room it cools, making it an entry point rather than a defense.
Close the outdoor air damper on a window unit and check the seal at the sash. If it will not close, do not run the unit in smoke. Skip single-hose portable air conditioners, which lower indoor pressure and draw smoke in through every other gap.
Without ductwork, the clean room becomes the whole strategy. Filterbuy would rather send a household to a sealed bedroom than sell a filter for a system they do not have. Pick the room where people sleep, seal it, and size a portable air cleaner to that room. Renters get the same protection without touching the building, and what the Air Quality Index measures tells you when to retreat.
MERV, short for Minimum Efficiency Reporting Value, rates how well a filter captures particles from 0.3 to 10 micrometers. MERV 13 is the tier federal guidance points to for wildfire smoke, and the highest most systems run safely. MERV 8 and MERV 11 work year-round but capture far less fine smoke.
MERV 13 is not equivalent to True HEPA, and Filterbuy will not pretend otherwise to sell a filter. True HEPA creates far more static pressure than a residential blower can overcome, so it belongs in a portable air cleaner or in-duct unit. Our comparison of MERV 13 versus HEPA for wildfire smoke covers the tradeoff.
Smoke also carries gases and odor compounds pleated media cannot capture, and we would rather say so than let a filter take credit for work it does not do. Filtration cuts the particle load, the fraction most tied to respiratory effects. A sealed envelope does the rest. See which MERV rating to use on high AQI days, or our MERV 13 pleated air filters.
MERV is defined under ASHRAE Standard 52.2. MERV 13 is not equivalent to True HEPA. Confirm your system can accommodate the tier before upgrading.
Smoke does not respect a property line or a state border. We have been manufacturing filters for over a decade and serving more than two million households, and Long Island shows why that matters. A family in Babylon can breathe smoke from a Canadian fire and their own Pine Barrens in the same year. The ones who come through comfortably had the right filter in the closet first.

National Interagency Fire Center. As of August 17, 2026, U.S. firefighters had responded to 48,960 wildfires burning more than 7.2 million acres, 169 percent of the ten-year average.
Town of Babylon. The Town of Babylon houses 218,223 residents in 65,994 households, making it the most densely populated town in Suffolk County.
American Lung Association. In the 2026 State of the Air report, covering 2022 through 2024, Suffolk County again received the worst ozone grade in the state.
Active fire status changes hourly. The AirNow Fire and Smoke Map shows current detections and plume coverage under ZIP code 11702.
On Long Island, late-summer haze is more often ground-level ozone than smoke. Read the advisory text, because a pleated filter does nothing for ozone.
Federal guidance points to MERV 13 or higher for systems that can take it. Confirm compatibility with a licensed HVAC technician before switching.
Do not let the house become dangerously hot to keep smoke out. Use cooling that does not draw outdoor air, or move to an air-conditioned building with filtration until conditions improve.
Preparation beats reaction. Keep a MERV 13 filter on the shelf so the next Babylon advisory is a ten-minute task, not a three-day wait. Check your filter frame for the size, then order a spare from Filterbuy. Shop MERV 13 filters for smoke season.
PM2.5: Airborne particles 2.5 micrometers or smaller, the dominant pollutant in wildfire smoke.
Air filter: A device in an HVAC return that removes solid particulates from circulating air.
