Reducing AIR Pollution Exposure to Lower Blood PRESSURE Among New York City Public Housing Residents (AirPressureNYC)

July 28, 2026 updated by: NYU Langone Health
Fine particulate matter <2.5 µm (PM2.5) air pollution is the fifth leading risk factor for global mortality, with the largest portion of deaths due to cardiovascular disease (CVD). While several mechanisms are responsible, PM2.5-induced elevations in blood pressure (BP) may be relevant. Indoor portable air cleaners (PACs) are a novel approach to reduce exposure to PM2.5 and potentially lower blood pressure. The current study is being conducted to provide evidence that PACs reduce PM2.5 exposure and lower systolic blood pressure (SBP) in key patient populations.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Active Portable Air Cleaner (PAC)
Using a double-blind randomized process, active PACs (with HEPA filters inside) will be assembled and placed in the bedroom of study participants. Initiation of the PAC devices will occur at baseline on Day 0. After completion of enrollment, consent and the placement of PACs, electricity monitors, and PurpleAir monitoring, the PAC will be turned on. Participants will be instructed to keep the PACs on in bedrooms during the study duration, closing bedroom doors at night and during the day, when possible. The PAC will run for 24 hours on Day 0 of the study protocol before the 30-day treatment period begins. A kilowatt meter will be installed with the PAC to monitor electricity usage as a measure of adherence.
Device: Active PAC
The active PAC will contain HEPA filters inside the device.
Sham Comparator: Sham PAC
Using a double-blind randomized process, sham PACs (with no filters inside) will be assembled and placed in the bedroom of study participants. Initiation of the PAC devices will occur at baseline on Day 0. After completion of enrollment, consent and the placement of PACs, electricity monitors, and PurpleAir monitoring, the PAC will be turned on. Participants will be instructed to keep PACs on in bedrooms during the study duration, closing bedroom doors at night and during the day, when possible. The PAC will run for 24 hours on Day 0 of the study protocol before the 30-day treatment period begins. A kilowatt meter will be installed with the PAC to monitor electricity usage as a measure of adherence.
Device: Sham PAC
The sham PAC will contain no HEPA filters inside the device.
