Airflow data.

No cannula.

No compromise.

Wesper Lab is the high-fidelity option for home sleep testing — FDA-cleared, cannula-free airflow, and built on direct measurement of chest and abdominal respiratory effort. Two wearable biosensor patches deliver a validated respiratory signal, night after night, without the failures associated with nasal cannulas.

Direct respiratory measurement. Validated to PSG.

Wesper Lab is the high-fidelity option for comprehensive analysis, comorbid patients, and confirmatory studies — anywhere direct respiratory data is mandatory. Every signal in the stack is FDA-cleared and AASM-aligned, captured through two wearable biosensor patches that work where cannulas fail.

FDA-Cleared HSAT

No Cannula.
No Hassle.
FDA-Cleared Airflow Data.

Wesper Lab’s two-patch design stays in place through the full study — no facial appliance, no cannula, no mid-sleep failures that force a retest. Reliable signal acquisition from lights-out to morning, study after study, patient after patient.
