Introducing the first healthy home system

Your home has a heating and cooling system for comfort. Yet it doesn’t have a healthy air system to ensure you breathe clean air. Since health and building science experts have proven that poor indoor air quality leads to respiratory conditions and many other illnesses, Panasonic created a solution for healthier indoor environments. Introducing Cosmos™, the first healthy home system.

Why do you need a healthy home system?

  • Indoor air quality (IAQ) is the #1 concern in healthy home building
  • Today’s tightly built homes trap all sorts of toxins inside, creating an urgent need for better ventilation
  • Poor indoor air quality is ranked as the 4th biggest environmental threat in the US
  • People spend about 90% of their time indoors, where harmful pollutants can be two- to five-times higher, according to the EPA
Cosmos is the first connected home system that addresses your family’s health

Troubling facts about bad indoor air quality

  • Health experts estimate that 35 million Americans suffer from upper respiratory tract symptoms that are allergic reactions to airborne allergens1
  • Women who work at home have a 54% higher death rate from cancer than women who work outside the home2
  • Long term effects from repeated exposure to bad indoor air quality include respiratory problems, heart disease and even cancer3

Expel harmful airborne toxins and excess moisture to breathe clean air

Cosmos monitors four of the most harmful sources of indoor air contamination: volatile organic compounds (VOCs), fine particulate matter, carbon dioxide and humidity.


Volatile organic compounds are toxic gases emitted from common items in your home. Furniture, carpeting, shower curtains, flooring, wood, paint and other common materials and cleaners emit volatile organic compounds such as formaldehyde, ammonia, xylene, benzene, and trichloroethylene. Repeated exposure to these chemicals can have short and long term adverse health effects.

Particulate matter 2.5

Fine particles (also known as particulate matter 2.5 or PM2.5) are tiny particles or droplets are less than 2.5 microns in width and travel through the air, into the respiratory tract and lungs. Medical studies show that particulates suspended in the air can be absorbed deep into the lungs, causing ailments such as chronic bronchitis, reduced lung function and even increased rates of lung cancer and heart disease.

Common sources of particulate matter include cooking vapors, burning candles & oil lamps, fireplaces, and kerosene space heaters.

Carbon dioxide

Carbon dioxide (CO2) build-up depends on a variety of factors. The number of people in a room, the amount of outdoor fresh air coming in, and combustion by-products contaminating the indoor air such as idling vehicles in garages and leaky furnaces – to name a few. While generally not found at hazardous levels in indoor environments, at high levels carbon dioxide can cause headaches, dizziness, nausea and other symptoms.


High humidity and condensation from hot showers, baths, leaks and poor caulking can lead to airborne mold spores and mildew, both of which can be hazardous to human health. Mold spores may go undetected at first and can spread quickly if not managed, making it a difficult – and potentially expensive – issue to remedy. Moisture can also cause structural damage to your bathroom, ruining expensive fixtures and cabinetry by encouraging rust and surface buckling.

It is important to manage excess moisture in the home before it causes permanent damage to and health problems. That’s where Cosmos goes to work.
