As dense smoke from regional wildfires spread through communities across western Montana last summer, public health agencies faced an indoor problem, too: Residents suddenly needed filters to clean the air inside homes and public spaces, but there was no obvious funding source to pay for it.
Ellen Leahy, the health officer in charge of the Missoula City-County Health Department, says in the past, when wildfire smoke polluted the air outside, nobody really talked about air filters.
“We’d always told people to go indoors, thinking the air might be a little better,” Leahy says. “Well that was not necessarily true anymore.” The size and proximity of fires, coupled with weather trends and local topography, led to an inversion layer of dirty air that hung around communities for weeks on end. Without air filtration systems, it invaded indoor spaces too.

“We put towels around the doors, the windows — everything,” Joy says. “It’s not dirt. Grime from the smoke came in through the whole house.”
“I’ve got less than 50 percent breathing capacity right now,” he says. “Anything that I could have done a year ago, I can’t do now. And then that smoke on top of it — it was killing me.”
But with no family in the state and limited mobility, the couple had to stay inside their house all summer. So Amy Cilimburg, who directs a small nonprofit called Climate Smart Missoula, helped the Dunagans get a HEPA air filter and make a safe air space inside their home. On the day I visit, she’s installing a second filter in their living room.
“It’s the same filter, so it works the same way,” Cilimburg explains.
The unit resembles a space heater, but can actually scrub out the fine particulates in wood smoke that are so hazardous to health.
“There’s a prefilter that takes out the large stuff, and then — that’s the HEPA filter,” Cilimburg says, pointing to another part of the device. “So you want to make sure that one’s in there.”Enlarge this image

In early 2017, Missoula County’s Health Department launched a pilot program with Climate Smart to get HEPA air filters to homebound seniors in Missoula ahead of the fire season. But when wildfire smoke swamped Seeley Lake last summer, they also started to distribute filters to residents who have a high risk of developing breathing problems and other health issues related to smoke pollution. Local health providers helped identify those people, including the Dunagans.
Don says he slept in his recliner, near the air filter, every single night while the smoke was bad.
“I believe that machine saved my life,” he says. “I really do.”
Then the wildfires dragged on into the school year. And kids, who are also extra susceptible to the pollutants because their lungs are still developing, sat in smoke-filled classrooms across the county.

Montanans Pitch In To Bring Clean Air To Smoky Classrooms
Missoula County’s health department and Climate Smart scrambled to get air filters to the schools most deeply enveloped by smoke. Other nonprofits pitched in to raise money and buy filters too. Almost overnight, the smoky haze inside classrooms disappeared.
The county health department’s Leahy says that strategy of finding a solution and taking action was a big shift away from the agency’s usual approach of issuing advisories to people to hunker down and stay indoors. And they need to keep acting, she says.
“There has to be a more concerted effort — which we are a part of — to provide clean, indoor air. Filtered indoor air. Messaging that the air isn’t good — isn’t enough,” Leahy says. “And that we have to plan to be able to do that, and deploy those systems much more quickly, as you would in an emergency.”
The challenge is figuring out who pays for it.
Portable HEPA air filters that can clean a big room cost just under $200 each. Even with a bulk discount, it cost about $30,000 to put those kinds of filters in just three of the 50 schools in the county last fire season. That didn’t even cover every classroom or grade, Leahy says.
Nor are individual filters necessarily the most efficient solution for schools and other big buildings — like daycare centers, nursing homes or health clinics — says Missoula county air quality specialist Sarah Coefield. It’s virtually impossible, Coefield says, to put a price tag on what it would cost to filter the air in every public space in the county.
“It would be a very high number, and I haven’t even wrapped my head around it,” she says.
Missoula County has one of the biggest and most experienced air quality programs in the state, but the health department was not equipped to launch response on a large scale, Leahy says.
The health department is set up to regulate easily controlled, man-made sources of air pollution — such as factories or wood stoves — and to issue health advisories. The money the county contributed at the last minute to buy filters came from emergency funds, which quickly dried up.
Health officer Leahy says they all tried their best to respond to the need.
“But it was very — it was creative,” she says. “I would say makeshift.”
Scientists predict wildfires are going to get worse, so public health departments are starting to see a need for a more proactive approach. That’s going to require still more creativity, says Leahy.
“There’s not a new source of funding that we’re aware of,” she says, “that can say, ‘Well, how can we at the local level try to help people with exposure to wildfire smoke in the same way that we at the local level try to do on wood stoves?’ There’s not a [funding] pathway for us to do that, at this time.”
The state health department is in a similar bind. Currently, they have no resources specifically dedicated to protecting the public from wildfire smoke.
“I don’t anticipate that there’s going to be a lot of new monies coming,” says Jim Murphy, the chief of the communicable disease bureau at Montana’s Department of Public Health & Human Services. “Given the state’s budget crisis, I think it’s maybe making the best of what we already have.”
Cilimburg of Climate Smart says she’s proud of Missoula’s leadership and of the community’s efforts to step up. But she stresses that wildfire seasons are getting longer and more intense — the smoke will come back.
“Providing some money up front can save you money down the road,” Cilimburg says. “And we’re just not very good sometimes at thinking about it. We’re good at responding to disasters, and not as good as being prepared for them up front. That’s kind of the conversations we’d like to spark.”
For now, the county health department will continue to partner with Climate Smart. This winter, they’re busy building on the foundation they established over the summer — spreading the word about the usefulness of air filters and the message that clean air is a collective responsibility.
The program has a cache of about 100 filters to help those in need. And they’re working with larger public institutions, like school districts, to help them improve their air filtration systems — and encouraging them to add such systems to their own budgets.
Dunagan says the responsibility is also on everyone who lives in the area to acknowledge the risks of living with wildfire, and to create their own clean-air space.
“A lot of people don’t realize what that smoke will do to you,” Dunagan says. “You might tough it out now, but if you go long enough, you’re going to have breathing problems.”
