Summary

This pilot project is a randomized, double-blind, sham-controlled trial investigating whether in-home air pollution reductions using portable air cleaners (PACs) can decrease circulating concentrations of biomarkers of inflammation. Using both a targeted approach to study the established biomarker TNFa and an exploratory approach with a commercially available proteomic panel, the researchers will measure concentrations of biomarkers before and after four weeks of home PAC use in a cohort of 74 adults with hypertension recruited from NYU outpatient clinical settings. Participants will also track home blood pressure measurements for additional exploratory analysis of potential mediation of PAC-associated decreases in blood pressure by biomarker concentration changes.

Conditions

Interventions

OTHER

Portable air cleaner (PAC)

Commercially available Portable air cleaners (PAC) contain carbon filters that reduce volatile organic carbons and can reduce odors. Because of this, the researchers will remove the carbon filters from all air purifiers to preserve blinding. This will be done by unblinded research staff and devices will be labelled with an ID number to preserve blinding of the rest of the research team.

OTHER

Sham Portable air cleaner (PAC)

Sham Portable air cleaner (PAC) are commercially available portable air cleaners with the carbon filters and the HEPA filters removed. This will be done by unblinded research staff and devices will be labelled with an ID number to preserve blinding of the rest of the research team.
