We protect your sleep. We also fund the research that protects your brain.
Cozy Sleep Systems pledges 1% of every purchase to Alzheimer's drug discovery research. Because the air you breathe during sleep doesn't just affect tonight — it shapes your cognitive health for decades to come.
Why Alzheimer's Research?
Recent peer-reviewed research has established a direct causal pathway between the air people breathe during sleep and their long-term risk of developing Alzheimer's disease. This isn't a loose association — it's a confirmed biological mechanism involving particulate matter crossing the blood-brain barrier and accelerating the buildup of toxic proteins.
Cozy purifies the air you breathe for 8 hours every night — the exact exposure window that research links to Alzheimer's risk. No other air purifier brand has built a position around this connection, and we believe we have both the opportunity and the responsibility to fund the research that could one day prevent this disease.

How the Program Works
Fund Drug Discovery
1% of every Cozy purchase goes directly to the Alzheimer's Drug Discovery Foundation (ADDF), which funds breakthrough drug discovery research targeting the root causes of Alzheimer's and related dementias.
Protect Brain Health
By purifying the air you breathe during sleep — the 8-hour exposure window that research links to long-term brain health — Cozy addresses one of the modifiable risk factors for cognitive decline.
Transparency & Accountability
We publish annual transparency reports showing exactly how much was donated, which research programs were funded, and what outcomes were achieved. No vague promises — verifiable impact.
About the Alzheimer's Drug Discovery Foundation
The Alzheimer's Drug Discovery Foundation (ADDF) is the only philanthropy dedicated to funding drug discovery for Alzheimer's disease, related dementias, and cognitive aging. Founded in 1998 by Leonard A. Lauder and Ronald S. Lauder, the ADDF has invested over $300 million in more than 750 research programs across 20 countries.
We chose ADDF over broader organizations because they fund drug discovery research directly — not awareness campaigns or general support services. Every dollar goes toward finding treatments and preventions for the disease itself. This aligns with our science-forward brand philosophy: measurable, targeted, evidence-based impact.
