The Nanoenvi® IAQ device enables continuous monitoring of indoor pollution parameters so that building managers/owners can make decisions to improve people’s health and welfare. The negative effects of poor air quality in indoor spaces affect many people, as it has been proved that city inhabitants spend a 60-80% of their time indoors, in places that are more or less polluted. Thanks to Nanoenvi® IAQ technology, wireless networks can be created indoors to transmit real-time information about breathing air to apps that the user can see from a computer, mobile phone or tablet. This helps decide when it is necessary to renew the air and ensure the quality of breathing air. Nanoenvi® IAQ brings high reliability air quality sensors for professional applications. The Nanoenvi® IAQ has been designed for working centres, classrooms, hospitals, conference rooms, garages, labs, cinemas, theatres, etc.; that is, any indoor area for public attendance.




With a compact and modern design, the Nanoenvi IAQ device can be easily installed in any room, whether in a tabletop or wall configuration, going completely unnoticed. The matrix of points that indicates the concentration of pollutants (CO2, CO, VOC, PM10 and PM2.5) stands out in its design, which allows, a simple view, to identify the indoor air quality of the room in which it is located.


Its modular electronics allow the integration of up to 5 sensors to choose from from a list of several dozen: from the usual temperature and humidity sensors to more advanced hydrocarbon sensors (VOCs).Regardless of their type, all the sensors installed in the Nanoenvi IAQ product are carefully prepared, one by one, in our calibration laboratory, thus achieving the precision, reliability and stability in the measurements required by the reliable detection of the concentrations of contaminants that they can be significant for people’s health and well-being.


Through standard protocols (Lonworks, KNX) Nanoenvi IAQ is able to interoperate with home automation systems provided by third parties. Nanoenvi IAQ equipment can be integrated into any IOT network through the usual M2M protocols: WiFi, 3G, Bluetooth, ZigBee, etc. Like all Nanoenvi devices, IAQ sensors comply with ENVIRA’s Plug’n Play policy, implementing “out of the box” connectors for integration with the IoT platform (both public and proprietary) selected by the client.

Made in EU

Nanoenvi IAQ devices are designed, manufactured and assembled in EU.



ANSI/ASHRAE Standard 55 is the American Standard that establishes the ranges of environmental conditions to achieve the optimal thermal comfort inside buildings. The Standard is assessed by subjective evaluation and defines the best indoor temperature for user satisfaction ranges between 20 to 22ºC (68 to 72 ºF).


A high relative humidity decreases sweating effectiveness in its body temperature control function, so more sweat is produced is temperature goes high, generating discomfort and sultriness. A low relative humidity cause dryness and itching. Optimal comfort is achieved with a relative humidity in the 30-60% range.


Barometric pressure affects to dew point and water condensation and is also related to the air flows causing bacteria, dust and other airborne pollutants.
If air pressure in the room is lower than outside, contamination from the room does not flow out into surrounding areas. Otherwise, higher pressure inside a room, will keep out pollutants.


Carbon Monoxide is a silent killer. It cannot be sawn or smelled. CO are in the air whenever fuel or other carbon-based materials are bunt. CO can cause dizziness, headaches, vomits and finally death. Event at low levels, long term exposition to CO can cause chronical hearth diseases and/or EPOC. New-borns, infants, pregnant women, elderly and people affected with respiratory diseases are the top-risk profiles. Vehicles, gas stoves, barbecues, generators and poorly maintained ventilation equipment are the most common CO sources at indoor locations.


Breathing becomes more difficult as carbon dioxide levels rise, causing tiredness and making harder to get focused. Rest and sleep quality are also affected by CO2. In closed areas, high levels of carbon dioxide can lead to health complaints such as headaches.


Volatile Organic Compounds (VOCs) are usual components in many building materials such as plywood, glues, paintings and personal care products (perfume, hair-sprays, lacquer, burnishes, etc.). Other VOC sources are burning gases, wood or tobacco. Exposure to VOCs can cause eye, nose and throat irritation, shortness of breath, headaches, fatigue, nausea, dizziness and skin problems. Higher concentrations may cause irritation of the lungs, as well as damage to the liver, kidney, or central nervous system. Long-term exposure may also cause damage to the liver, kidneys or central nervous system.
People affected with asthma are more exposed to VOCs effects.



PM2.5 (particles less than 2.5 micrometers in diameter) can penetrate deeply into the lung, irritate and corrode the alveolar wall, and consequently impair lung function. PM2.5 may therefore be capable of carrying various toxic stuffs, passing through the filtration of nose hair, reaching the end of the respiratory tract with airflow and accumulate there by diffusion, damaging other parts of the body through air exchange in the lungs. The elderly and those with pre-existing cardiopulmonary problems are more exposed to PM2.5 effects.


Exposure to high concentrations of PM10 can result in health impacts ranging from coughing and wheezing to asthma attacks and bronchitis to high blood pressure, heart attack, strokes and premature death. The young and old and persons with existing medical conditions are most likely to be adversely affected by exposure to high PM10 concentrations.


Nanoenvi IAQ calculates an index of ambient air quality that measures the level of health and well-being in indoor spaces. Users will be able to know the quality of the air they breathe through color codes.

The possible values ​​of the index move in the range 0-7, where:

  • 7 optimum quality (blue LEDs).
  • 4-6 good quality (green LEDs).
  • 2-3 moderate quality (yellow LEDs).
  • 0-1 poor quality (red LEDs).


There are two connectivity options for Nanoenvi IAQ devices: WiFi or LoRa. Both options are designed for easy installation and configuration while providing end users with open APIs to integrate IAQ devices into 3rd party platforms and applications.

Remember that, due to our #CloudFree politics, APIs are ever provided at device level, so your applications interoperate directly with Nanoenvi IAQ devices, without a mandatory cloud proxy. Of course, cloud APIs are also available…if you decide to go up to the clouds.


Measuring Air quality inside schools

Children are most sensitive to air pollutants, so monitoring the air at schools is an excellent tool for the prevention of respiratory diseases. It has been proved that an adequate control of ventilation improves the students’ academic performance by reducing CO2 levels.

Measuring air quality for people with respiratory diseases

The flexibility of the Nanoenvi® IAQ installation allows people with asthma or other respiratory problems to know about the air quality indoors, and whether the air they are breathing is adequate for their condition.

Shopping centers

At malls and shopping areas, higher TVOC concentrations are usually caused by low efficiency of the air exchange and intake systems or by large quantity of articles stored in small spaces. Highest total VOC concentrations are commonly present during cleaning activities and that these activities were carried out frequently in food departments and other critical areas for VOC levels. Elevated VOC concentrations are event found in retail spaces with no apparent emission sources due to their proximity to other retail spaces with emission sources. Nanoenvi IAQ devices provide managers with valuable data about the air quality inside shops, aiding them in decision making regarding to cleaning activities planning, product storage quantities, etc.

Workplaces and offices

Common symptoms of poor air quality at a workplace are physical fatigue, headaches, allergic reactions and eye and throat irritation. High CO2 and VOC concentrations can cause a significant reduction in cognitive activity performance. Nanoenvi® IAQ devices can identify the sources of poor air quality at the office.


Often guests do not complain about a stuffy environment, but they are unlikely to repeat such unpleasant experience. Real time monitoring of indoor air quality enables hotel clean and maintenance operations to be optimized, granting ever pleasant air conditions for visitors and guests. Real time monitoring also enable hotel companies to be certificated with the most renowned seals of quality in green tourism, energy efficiency (such as, i.e, Wall Certificate) and customer experience.

SPAs and Beauty Centers

Beauty centers need to achieve and maintain high standards of hygiene, health and safety. Parlours customers and workers are exposed to a wide range of chemicals. Hair sprays, bleaches, permanent waves and other products usually contains hicgh levels of volatile organic compounds (VOCs), which are associated with asthma, dermatitis and other diseases. These levels of volatile organic compounds could be decreased significantly by following good practices such as appropriate ventilation of the areas, closing the packages of the beauty products when not in use and finally selecting safer beauty products. Nanoenvi IAQ solution provides beauty parlour workers with real-time information about silent hazards like VOCs and other pollutant levels.

Leisure areas

Poor air quality at recreational settings is considered among the top most conditioning factors for user’s comfort. Large people concentrations are not unusual in libraries, museums, cinemas, theatres, clubs or meeting rooms, causing high CO2, temperature.

Gyms and Sports Centers

The journal Building and Environment, in it’s 2014 study about air quality in Gyms and Sports Centres, found unacceptably high levels of carbon dioxide, formaldehyde and other organic volatile compounds (VOCs), and particle pollution in multiple European and US indoor fitness centres. High CO2 levels, make it harder to breath, driving to poor performance in cardio workout. Particles pass through nasal cavities and enter the lungs, causing health problems. Over a quarter of the gyms exceeded the European fixed indoor limit for PM10 (particles which size is up to 10micras). They came from rubber meats, metal plates banging together, dust and dead pieces of skin from other people. Regular cleaning can help, but cleaning products usually are made of VOCs and other pollutants…and high VOC levels can cause skin irritation, neurotoxic and hepatoxic effects, making people tired and unfocused. Nanoenvi IAQ devices aid sports centres managers in decisions such as when to recirculate air vs. increase the amount of fresh air, what are the optimal cleaning schedule, which are the most adequate cleaning products, etc.


Industrial and other professional activities such as car repair shops, professional painters, plumbing or soldering shops, etc. demand the application of chemicals and other potentially hazardous products. Oils, lubricants, paintings are common sources of high levels of Volatile Organic Compounds (VOCs), causing skin irritation and neurotoxic or hepatoxic effects. Metallic or organic dust particles, coming from cutting, melding, soldering, polishing or other common activities in workshops are, in their smallest sizes (below 10 micras), small enough to enter the lungs, mixed with other air pollutants, causing coughing and discomfort and health problems in the long term (EPOC, bronchitis, …) Nanoenvi IAQ devices are designed to perform as air quality monitor for workshop and industrial facilities, warning when high pollutants levels are detected and when unsafety conditions for the health in the log term are sustained over large periods.


IAQ in healthcare facilities is affected by several factor related to the occupants, their activities, building layout and its materials, ventilation and thermal parameters, maintenance, and cleaning activities. It is reported that 5% of all patients who go to hospitals for treatment will develop an infection while they are there. There is a strong and sufficient evidence to demonstrate the association between ventilation, air movements in buildings and the transmission spread of infectious diseases such as measles, tuberculosis, chickenpox, influenza, and sars etc. Air re-circulation for energy saving or using chemicals for cleaning are often in the side of the problems and not in the solutions. Continuous monitoring is a valuable tool to prevent indoor air pollution.
