Low Cost Monitoring Project (LCMP)

What is the LCMP?

reading Radon monitor,

The Low Cost Monitoring Project (LCMP) is a free program that uses low-cost monitoring devices to address indoor air quality.

We invite anyone who might be interested in joining LCMP to attend a webinar to introduce the program and answer questions about monitoring and improving indoor air quality. After the webinar, you can decide whether you want to become part of our next cohort.

Participants in each LCMP cohort—mostly residents but some workplace representatives and building professionals, too—receive a loaner kit of 7 devices that measure indoor and outdoor particles, CO (carbon monoxide), CO2 (carbon dioxide), radon, temperature, and humidity. Kits are delivered to your home (or sent through the mail if you live outside of western Pennsylvania). ROCIS will guide you in the usage of the monitors and help make sense of the information that comes rolling in.

Over the course of four weeks, the ROCIS monitors gather data about the air inside and outside participants’ homes. During this period, LCMP participants can test the effectiveness of ROCIS-loaned equipment, including an induction stovetop and/or DIY filter fans.

ROCIS supports each cohort of participants with educational sessions about air pollution, tools for managing and interpreting data, and targeted suggestions for how to improve the air in the places they live and work. These online sessions cover a wide range of topics including:


  • Accessing and interpreting air quality monitoring results
  • Behavioral and technical interventions to improve indoor air quality
  • Implications of local ambient air quality—and the tools to track outdoor air quality
  • Health impacts of poor air quality

We’re proud to say that our LCMP participants tend to become champions for clean air. Once you know the impacts of air pollution and have the tools to do something about it, it is hard to go back. It’s amazing what a little knowledge can do!

LCMP Testimonials


The ROCIS program is one of the best educational programs around! We all know air quality in Pittsburgh isn’t great. This program allows you to understand how the outdoor air quality affects the indoor air quality, and what you can do to create a healthier environment in your home. By allowing you to utilize their sensors and monitors, they help you understand your indoor air quality. They also loan intervention equipment to see what can help your home the best. The team behind this program really cares and wants to help! I can’t recommend it enough. Thank you for everything again!

Mark E. (Cohort 54)

Thank you and your team again for all the info and strategies [for] keeping our air quality inside as safe as possible. We feel especially fortunate during the recent air quality alerts resulting from the Canadian wildfires. Specifically, I am thankful for the idea of running the fan on our furnace system during these times to continuously filter our indoor air. I would not have considered this strategy without participating in cohort-54. I can tell a difference in my breathing inside and being outside.

Ann (Cohort 45)

I was grateful to be a part of the ROCIS Virtual Cohort. The time and effort to participate were well worth it. My family and I feel we now have a greater understanding of our indoor and outdoor air quality and how to make changes to improve it. Thank you to everyone at ROCIS for this great opportunity!

Gail (Cohort 57)

I didn’t realize […] how much fun I would have learning new things and how much my life would improve.

Nancy (Cohort 59)

The ROCIS program has been so helpful to us and we feel that we can now live in our new city of Pittsburgh in a much healthier manner indoors. We are so grateful to have had this opportunity.

Susie Wood

I appreciate all of your time and expertise through this great process. I am so happy that I have had the opportunity to see the pollution outside my house and see the impact the mitigation strategies you suggest can make. Your process is truly effective. It has been so eye-opening and fun. Thank you again for everything.

Kevin (Cohort 47)

Dara & I are grateful to have been part of ROCIS Cohort 47. It was a privilege to glimpse this part of our invisible world and learn more of the health connections. Gaining a better understanding of our indoor air and our air shed—the large numbers connected to such small particles from everyday activities—was an eye opener. The data, analysis, insights, shared experiences and web resources were invaluable. And we now have an important IAQ baseline for our planned renovations!

Jo and Tim Resciniti – West Deer Twp. (Cohort 53)

The air outside is frequently unhealthy in the greater Pittsburgh area, and we were worried about how much pollution was making its way into the house. Being part of the LCMP helped us to be aware of the sources of harmful particles in our home, how our daily activities directly contribute, and gave us tools to address problems with our indoor air quality.

Beth Burrell (Cohort 33)

Participating in the ROCIS Low Cost Air Quality Monitoring Cohort 33 provided access to a lot of valuable information that I used to learn how to provide the healthiest environment possible for my family at home.

Ned Ketyer, M.D. (Cohort 57)

ROCIS’s low-cost monitoring project (LCMP) opened my eyes to how much poor outdoor air quality and my daily indoor activities affect the air quality inside my house. The program was very well organized and fun to participate in. I expect the knowledge I learned and the changes I made to improve my indoor air quality will result in better health for me and my family.

The ROCIS Low Cost Monitoring Project is full of success stories.
