Wildfire Smoke Is Affecting Oregon and Washington: Here's How to Keep Your Indoor Air Cleaner

Wildfire Smoke Is Affecting Oregon and Washington: Here's How to Keep Your Indoor Air Cleaner

August 07, 2026

Large wildfires throughout Washington and Oregon can send smoke1 across the Pacific Northwest for days or even weeks. Changing wind patterns often carry fine smoke1 particles into cities hundreds of miles away, including Seattle, Portland, Spokane, Eugene, Bend, Tacoma, and surrounding communities.

As wildfires continue to burn across Oregon and Washington, many families are once again dealing with smoky skies, reduced visibility, and declining air quality. According to CNN's wildfire maps and satellite imagery, dozens of large fires are burning across the Pacific Northwest, with smoke1 plumes stretching hundreds of miles and affecting communities far beyond the active fire zones. The fires have prompted evacuations in some areas, while changing wind patterns continue to carry smoke1 throughout the region.

While you can't control what's happening outdoors, you can take steps to improve the air inside your home. One of the most effective ways to reduce airborne smoke1 particles indoors is by using a high-quality HEPA air purifier.

Why Wildfire Smoke1 Is More Than Just an Outdoor Problem

Even when your windows and doors are closed, wildfire smoke1 can find its way indoors through small gaps around doors, windows, doggy doors, ventilation systems, and every time someone enters or leaves your home.

Wildfire smoke1 contains a mixture of:

  • Fine particulate matter (PM2.5)
  • Ash and soot
  • Dust3
  • Smoke1 Odors1
  • Other airborne pollutants created from wildfires

The smallest particles are often the biggest concern because they can remain suspended in the air for hours and easily circulate throughout your home.

Why Indoor Air Quality Matters During Wildfire Season

To establish a cleaner indoor environment, it is important to limit the infiltration of outdoor air when appropriate and continuously filter the air already inside your home.

Although many individuals spend significantly more time inside during periods of heavy smoke1, indoor air is not automatically clean.

In fact, each time an exterior door opens or your HVAC system draws in outside air, additional smoke1 particles can enter and accumulate in your living space if it is not continuously filtered.

How a HEPA Air Purifier Can Help

A HEPA air purifier continuously circulates and filters indoor air throughout the day.

PuroAir air purifiers are designed with a multi-stage filtration system that includes:

  • High-efficiency HEPA filtration to filter airborne particles, including many fine smoke1 particles.
  • CarbonTechTM activated carbon filtration to help reduce smoke1 odors1 and other household odors1.
  • Continuous air circulation that helps clean the air throughout the room instead of relying on particles to settle.

Rather than simply masking smoke1 smells, an air purifier actively filters many of the airborne particles contributing to poor indoor air quality.

Tips for Keeping Indoor Air Cleaner During Wildfire Smoke1 Events

If wildfire smoke1 is affecting your area, these steps can help reduce indoor smoke1 exposure:

✓ Keep Windows and Doors Closed

When outdoor air quality is poor, keep windows and exterior doors closed as much as possible to limit smoke1 entering your home.

✓ Run Your Air Purifier Continuously

During active smoke1 events, it's often beneficial to let your air purifier run 24 hours a day. Continuous filtration helps remove new particles as they enter your home. Even during times with great weather, we recommend running your purifier 24/7.

Replace Filters When Needed

Smoke1 can place additional demand on air purifier filters. Check your filter indicator regularly and replace filters every 3 months, or sooner with higher demand.

✓ Minimize Indoor Sources of Smoke1

Avoid activities that generate additional indoor particles, such as:

  • Burning candles
  • Using fireplaces
  • Frying foods at high temperatures
  • Burning incense

Reducing indoor smoke1 sources allows your purifier to focus on filtering wildfire smoke1 that enters from outside.

✓ Monitor Local Air Quality

Wildfire smoke1 conditions can change quickly depending on wind direction and fire activity. Monitoring your local Air Quality Index (AQI) can help you decide when it's best to stay indoors and keep your purifier running. A great resource to keep track of the air quality in your area is airnow.gov.

Who Benefits Most from Cleaner Indoor Air?

Everyone can appreciate cleaner indoor air during wildfire season, but it's especially important for:

  • Families with young children
  • Older adults
  • Pet owners
  • People working from home
  • Anyone spending extended periods indoors

Creating a cleaner indoor environment can make your home a more comfortable place while outdoor conditions improve.

Prepare Before the Next Smoke1 Event

Wildfire seasons have become longer and more intense across the Pacific Northwest, making indoor air quality an increasingly important part of home preparedness. Current forecasts indicate that smoky conditions may continue to affect portions of Oregon and Washington as active fires persist and weather patterns shift.

Having an air purifier ready before smoke1 arrives means you're prepared to begin filtering indoor air immediately when conditions worsen.

Breathe Clean Air with PuroAir

PuroAir air purifiers assist in establishing a cleaner indoor atmosphere by continuously filtering out airborne particles and diminishing persistent smoke1 odors1, regardless of whether you are facing heavy smoke1 currently or planning ahead for upcoming wildfire seasons.
