Where We Breathe 2014-Present
Where We Breathe is a project of Public Lab's Open Air Initiative focused on domestic formaldehyde monitoring and mitigation. WWB is composed of four interconnected aspects:
An online platform: where community members can pair test results to the symptoms they register in an etymologically validated survey, share stories about the impact of air pollution in their communities, and find support and resources for advocacy.
A lending library: which will foster for maximum use of test kits at a minimum price and allow for our DIY devices to make inroads into the marginalized populations that need them most.
A DIY test kit: conveyed by the lending library, bought in the Public Lab store or made on your own, will detect formaldehyde down to 5ppb and yields results in a thermometer like readout after a 30 minute sample (ie. no need to send samples to the lab).
A DIY remediation kit: also conveyed by the lending library, bought in the Public Lab store or made on your own, will help reduce the atmospheric load of formaldehyde in your home by circulating air though the root system of plants know to for their formaldehyde remediation capacity. This simple enhancement could increase the plant's ability to scrub the air of formaldehyde by as much as 100 times.
WhereWeBreathe was developed address non-place based environmental justice issues that revolve around toxic exposures emanating from distributed infrastructure (e.g. manufactured housing, Lumber Liquidators flooring, natural gas compressor stations). To this end it re-imagines epidemiological research tools around community needs. It re-frames epidemiological surveys as a forum for community peer-support and knowledge building.
Rather than treat participants as research subjects, this project creates a safe and anonymous-by-default space to share stories, symptoms, and resources, while re-imagining the alliance between affected communities and researchers.

Why domestic air quality?
Despite the long held observation that indoor chemical concentrations are generally higher than corresponding outdoor concentrations and that Americans spend ninety percent of their time indoors, the home is the last environmentally unregulated airspace in the United States. As both a major seat of exposure and regulatory void, indoor air quality is ripe for research-to-action interventions. Further, domestic exposures are often tied to racial and socioeconomic health disparities, making indoor air quality an environmental justice issue as much as it is a public health issue.
Formaldehyde is the most common and most toxicologically understood indoor air pollutant. This chemical vapor is a gateway to understanding commonplace domestic exposures. It is used as a setting agent, binding together particle board walls, subfloors, hardboard cabinetry and adhering carpets to their backing. As a result of its prevalent use in home construction, formaldehyde is a dominant contributor to cancer risk from the indoor environment and gives rise to a broad range respiratory, dermatological and neurological pathologies.
Why manufactured housing?
Although understudied, research indicates that formaldehyde levels in manufactured homes are on average four times higher than those of conventional homes. These high chemical concentrations in manufactured housing are due to the high use of engineered woods that utilize formaldehyde as a binding agent, the high ratio of exterior walls to indoor airspace and minimal
Large, understudied and underserved population
Manufactured housing is the largest source of non-subsidized affordable housing in the United States. While the exact number of manufactured housing occupants is unknown, it its commonly estimated that 20 million lower and moderate-income Americans currently reside in manufactured housing. Manufactured homes have an outsized share of the low cost housing market, representing 1 in 6 owner-occupied housing units with costs less than $500 per month. The median net worth of households that live in manufactured housing is one-quarter of the median net worth of other households.
Chemical awareness without resources
Formaldehyde has been a notorious issue among manufactured housing communities for over 30 years. Recent investigative reporting such as the 60 Minutes exposé on the high rates of formaldehyde emanating from Lumber Liquidators laminate flooring have raised public concern about this chemical. This longstanding problem in conjunction with recent media attention have sparked a great deal of interest in and demand for formaldehyde test kits among manufactured housing inhabitants, yet these are precisely the groups that cannot afford testing and are not networked in a way that can build strong toxic tort cases which can lead the way towards industry and regulatory reform.
