As a newly established nonprofit dedicated to developing high-quality, low-cost air purifiers, we at Air Support Project have witnessed this crisis with heavy hearts—but also with profound gratitude for the extraordinary individuals, nonprofits, and businesses that have rallied to bring hope, relief, and cleaner air to so many.

 

This blog post highlights the powerful efforts of those who stepped up during one of LA’s most trying wildfire seasons. Their work offers a blueprint for handling any air quality emergency—one that demands ingenuity, collaboration, and an unwavering commitment to health and well-being. Wildfire smoke hazards affect indoor air quality, even in areas far from the flames. Let’s take a closer look at what you can do to prepare and protect yourself, by following the lead of heroes in the community and beyond who are helping to make clean indoor air accessible to all.

The Community Heroes: Nonprofits Leading the Way

Wildfire smoke doesn’t remain outdoors; it seeps into homes, schools, and workplaces, posing a serious health threat. In response, groups like The Corsi-Rosenthal Foundation (CRF) have been at the forefront of grassroots action. The CRF has delivered more than 1,000 lifesaving do-it-yourself (DIY) air purifiers—widely known as Corsi-Rosenthal Boxes or CR Boxes—to those in need. In one remarkable effort, board member Liesl McConchie and a 50-person volunteer team assembled over 400 CR Boxes in just 12 hours, providing immediate relief to thousands suffering from wildfire smoke. Further amplifying the foundation’s impact, board member Dr. Kim Prather developed innovative shrouds that enhance each box’s effectiveness—showcasing the transformative power of science and compassion working in tandem.

 

Joaquin Beltran continued this momentum with Action Care Equity by distributing 200 DIY air filters donated by CRF to the Pasadena Job Center in just two days. This effort involved extraordinary community partners such as Midnight Books LA, Peace and Freedom LA, The Ace Coalition, and many generous volunteers. They proved that when local groups join forces, even the most daunting challenges can be tackled head-on.

 

If you’re inspired to take similar action, we have easy-to-follow instructions on building DIY air purifiers—cost-effective solutions that can make a life-or-death difference during smoke events. These DIY purifying units (CR Boxes) can be made for approximately $100, are easy to assemble with products you can get at your local stores, and work better than most HEPA purifiers on the market.

Infographic titled 'Make Your Own Corsi-Rosenthal Box or DIY Air Cleaner' providing instructions for creating a DIY air purifier. The top section introduces the benefits of the DIY air cleaner, explaining that it removes harmful particles such as pollen, dust, viruses, wildfire smoke, and pet dander from the air. Step 1: Materials required include a 20-inch box fan, four MERV 13 filters (20x20x1" or 20x20x2"), duct tape, cardboard (which can be from the fan box), and scissors or a box cutter. Step 2: Prepare the shroud by cutting a 20"x20" square of cardboard, drawing a circle with a 14" diameter onto it, and cutting it out. Place the piece with the hole on top of your fan and securely duct tape it into place to prevent back-flow. Step 3: Arrange the box parts by placing the filters with their airflow arrows pointing inward into the shape of a square, and taping at seams. Place the fan on top of the box, facing upward to direct airflow out, and tape it in place. Cut a 20"x20" square of cardboard to become the base of the box, and tape. Step 4: Assemble and seal by checking to make sure everything is oriented and aligned correctly. Tape the structure together at all joints and tightly seal the edges to prevent leakage of air. Write the date of assembly on the unit. Replace filters two times a year or when they look dirty. Step 5: Place the purifier and plug it in, ensuring the air purifier is unobstructed with a 1-3 foot radius around it. The center of the room elevating above floor level is best. Avoid placing it near ventilation sources like open windows. For best results, run it on the highest setting, smoke permitting. Estimated smoke CADR: 235 cfm.

Mask Blocs: Grassroots Superheroes

Outdoor air quality is hazardous in areas experiencing wildfires, making respiratory protection vitally important. Wearing a high-quality mask, such as an N95 or similar respirator, during wildfire events is crucial for protecting your health. Wildfire smoke contains harmful fine particulate matter (PM2.5) and toxic gases that can penetrate deep into the lungs, causing respiratory irritation, exacerbating existing conditions like asthma, and increasing the risk of long-term health issues. Masks designed to filter out fine particles provide an effective barrier, reducing exposure and helping safeguard both short- and long-term well-being. When the air outside is unbreathable, these measures become essential, not optional. 

 

In response, groups like Mask Bloc LA, Clean Air LA, Airgasmic LA and Clean Air Claremont leapt into action, distributing N95 respirators and other protective gear directly to those most in need. A heartfelt shoutout to the members of Clean Air Claremont, including Samson, Maga, Crystal, and Nicklepin for their incredible effort in building 90 air purifiers, entirely funded by community donations. This inspiring initiative, driven by (Claremont area students, faculty, staff members, and community members of the San Gabriel Valley, Inland Empire, and Orange County), demonstrates the power of collective action in addressing air quality challenges during the LA wildfires and making a meaningful difference for those most affected.

As highlighted by the Public Health Action Network, these pop-up operations effectively bypassed bureaucratic delays, ensuring that low-income and often overlooked communities received the critical protection they needed. Mask Bloc Seattle further amplified these efforts by donating over 2,000 respirators, significantly expanding the reach and impact of Mask Bloc LA’s vital work.

 

Babs is an artist and activist who has lived with lupus since childhood, channeling their personal experience into advocacy for stronger public health measures. As an organizer of Mask Bloc LA, they’ve been at the forefront of mask distribution and air purifier efforts in LA, earning widespread praise from the community, which expresses unwavering confidence in Babs’ commitment and leadership.

Corporate Contributions: Amplifying Impact

Beyond grassroots efforts, several businesses leveraged their resources and networks to help. Amoeba Records transformed its location into a distribution hub for masks and air purifiers alongside Dustin Drury, an organizer with Clean Air LA. Meanwhile, Medify Air donated 500 HEPA air purifiers through FEMA to the Los Angeles Dream Center, plus over 100 purifiers and many replacement filters to local community groups for distribution. The company is offering emergency pricing for all bulk orders and free local delivery, and Medify is matching all January online purifier sales by donating units of equal or greater value to those in need—a model of tangible generosity in action.Flo Mask—a reusable respirator company that provides adult and child sized elastomeric masks—offered a 30% discount with the code “CaliStrong,” ensuring high-quality masks reached as many Californians as possible. Nonprofit Smart Air donated air purifiers to amplify community efforts, illustrating how business goals can align powerfully with lifesaving relief initiatives. Armbrust mask manufacturers also stepped up, enabling organizations like Mask Bloc LA to distribute 180,000 duckbill masks. Additionally, Air Gradient is offering a free air quality monitor to those affected by the Los Angeles wildfires. 

 

Bona Fide Masks made a significant impact during the wildfire crisis by donating 250,000 Powecom KN95 masks to support communities in need. Recipients included organizations like the LA Dream Center, Pasadena Community Job Center, First UMC Pasadena, Mask Bloc LA, Airgasmic LA, and others. For more information on donations, their email is donations@bonafidemasks. These masks provided essential protection against harmful wildfire smoke, ensuring vulnerable populations had access to reliable respiratory safety. 

 

ElastomaskPro, as highlighted in their tweet, has been an advocate for the use of elastomeric respirators in addressing air quality concerns during crises. Their current promotion offers $40 off with the code “EASY24,” encouraging accessibility to their durable respiratory safety solutions. These collective efforts underscore the vital role businesses can play in life saving initiatives during times of crisis.

Government Aid

The Residential Air Filtration Incentives program by the South Coast Air Quality Management District (South Coast AQMD) aims to reduce indoor exposure to particulate matter (PM) for residents in specific AB 617 communities, including East Los Angeles, Boyle Heights, West Commerce, and Eastern Coachella Valley. Eligible residents can receive free portable air filtration units equipped with certified High-Efficiency Particulate Air (HEPA) filters, capable of removing 99.97% of particles from indoor air. The program also provides replacement filters and is currently accepting applications on a first-come, first-served basis until funds are exhausted. 

Knowledge Is Power: Virtual Events and Community Dialogues

In any crisis, knowledge can be as vital as physical resources. Wildfire smoke is a cocktail of harmful substances—particulate matter (PM2.5), carbon monoxide, benzene, and formaldehyde, to name just a few. Even healthy individuals can experience coughing, eye irritation, and respiratory issues; for those with preexisting health conditions, the stakes are even higher. 

 

To address the threats of wildfire smoke and respiratory illness, Mask Together America hosted a virtual session titled “Double Emergencies: Viral Surge + Wildfire Smoke Expert,” offering practical tips on respiratory protection and home safety. On January 15, Coalition for Clean Air held a webinar The Fires: Air Quality, Public Health and What to Do Next Webinar Summary.

what's in the air we breathe?

On average, we breathe 6 liters every minute, mainly indoors. Indoor air quality is often worse than outdoor air which underscores our need for cleaner air and safer spaces. Our air is made up of microparticles such as dust, pollen, mold, viruses, pet dander, and VOCs. These particles can enter our bloodstream through our lungs after we inhale them. The air we breathe impacts our daily and long-term well-being and health. Follow us at Air Support Project. We want you to know better so you can breathe better.

KNOW BETTER, BREATHE BETTER.
