Monitor Your Air, Protect Your Health

Plug-in, Long-Term Indoor Air Quality and Radon Survey Monitor

lüft™ is the first plug-in, Indoor Air Quality (IAQ) monitor to not only measure Chemicals (tVOC), Carbon Dioxide equivalent (eCO2), Temperature, Barometric Pressure, and Humidity, but also Radon. Radon is the leading cause of lung cancer of non-smokers causing an estimated 20,000 deaths in the US alone, every year! lüft's reliable, accurate detector technology is based on SunRADON’s proven suite of professional Radon monitors.

What is Radon?

Radon is a naturally occurring, radioactive gas that you cannot see or smell. Radon is normally found at very low levels outdoors but can accumulate in the air in homes and other buildings. Breathing in elevated levels of Radon over long periods can lead to health issues, including lung cancer. In fact, Radon is the leading cause of lung cancer among non-smokers, according to the EPA.

Why a long-term Radon monitor?

Radon levels fluctuate based on your home’s ventilation, airflow, weather conditions, and seasons. Furthermore, changes or deterioration of the foundation, windows, isolation, and vapor barriers, to name a few, can impact Radon levels. Therefore, long-term, continuous Radon level monitoring will provide the peace of mind even post Radon inspection and mitigation.

What are tVOC's?

A Volatile Organic Compound (VOC) is defined as any compound containing carbon that can be readily vaporized, except methane. VOC's, measured in totality of its mixed gases or tVOC, are released into indoor environments from cleaning and disinfecting products, paints, wood preservatives, carpeting, building materials, aerosols, insect repellents, microbial growth, and a host of other sources.

Why monitoring tVOC's?

At elevated levels, VOC's can cause eye, nose, and throat irritation; headaches, loss of coordination, nausea; damage to liver, kidney, and central nervous system. Some organics (such as Benzene) are suspected or known to cause cancer. Key signs or symptoms associated with exposure to elevated levels of VOC's include eye infections and irritation, nose and throat discomfort, headache, allergic skin reaction, shortness of breath, signs of poisoning, nausea, vomiting, nose bleeding, fatigue, and dizziness.

What are CO2 equivalents?

Carbon dioxide (CO2) equivalents, or short eCO2, are derived from the measurements of the mixed gases, tVOC's, and describe the quality of indoor air in equivalent units of CO2. Traditionally indoor air quality is limited to the measurement of temperature, humidity, and carbon dioxide alone. eCO2, however, follows increasing CO2 levels but also contains information about additional harmful mixed gases and odorous events, while a CO2 sensor detects just the exhaled CO2 from the room’s occupants.

Why SunRADON's lüft™?

Our home monitor is uniquely designed to continuously measure the quality of the air you breathe by measuring Radon as well as dangerous Chemicals (tVOC's), Carbon Dioxide equivalents (eCO2), Temperature, Humidity, and Pressure - to ensure the air you and your family breathe is healthy.
