CO2

As more people occupy a space, carbon dioxide levels rise, and there is less fresh air.
Indoor exposure to this gas can affect performance and decision-making and can also
cause headaches, restlessness, and drowsiness. That is why it is important to act when
levels shoot up in working environments, schools, hospitality, and gyms, either by reducing
the number of occupants in a room or increasing the ventilation rate (natural or mechanical).

Nanoenvi IAQ uses a high stability and precision NDIR sensor with autocalibration capability
for CO2 measurement.

COVS

Volatile organic compounds are toxins released by chemicals (cleaning and disinfection
products, paints, varnishes, waxes, cosmetics, perfumes, deodorant, air fresheners, etc.).
VOCs can cause serious health effects in the short and long term, such as minor eye, nose,
and throat irritations to liver and kidney problems.

If the COV levels increase, it is advisable to increase ventilation or open windows to
improve indoor air quality.

PM (1, 2.5, 4 and 10)

The suspended particles, also known as PM (1, 2.5, 4 and 10), are composed of a range of
dust, dirt, and liquid particles that are suspended in the air. Dust, fungi, bacteria,
and pollen are examples of particles.
The smaller and invisible they are (such as PM 1 or 2.5), the more harmful they are to
health, because they can be inhaled and penetrate the deepest parts of the respiratory
system, causing problems such as asthma and allergies to cancerous diseases.
PM particles can stay in the atmosphere for quite some time and are freely transported
by air currents. If these are released by a cough or sneeze, they can cause viruses or
bacterial infections. High PM levels may indicate the need to use air filters or to review
the filters of HVAC systems to mitigate exposure.

CO

Carbon monoxide is present in ambient air when fuel or other carbon-based materials are in contact.
Short-term exposure may cause dizziness or headaches, and long-term causes can lead to respiratory
diseases. Vehicles, gas stoves, barbecues, generators, and ventilation equipment with lack of
maintenance are the most common sources of CO in closed places.

Temperature

Optimal temperature conditions range from 20°C to 23°C. Any temperature above this range can result in
mental fatigue and affect performance and productivity. On the other hand, low temperatures can weaken
the immune system and help the spread of viruses. Real-time temperature monitoring will allow you to
make decisions such as adjusting the cooling system thermostat or deciding whether to open or close
windows.

Humidity

Indoor spaces humidity can be increased by the deterioration of construction materials in buildings,
water damage, and poor pipe systems. It is recommended to always maintain relative moisture levels
indoors between 40% and 60% to enjoy a healthy space and prevent the spread of viruses. Low levels
of relative humidity can affect performance and cause dry and eczema-prone skin. On the other hand,
high levels of humidity contribute to the proliferation of mold and, consequently, increase the risk
of asthma, allergy, and respiratory diseases.

Atmospheric Pressure

Atmospheric pressure is related to air flows that cause bacteria, dust, and other pollutants in the air.
If the air pressure in an indoor space is lower than on the outside, the room’s pollution does not flow
into the surrounding areas. Greater pressure within an indoor stay will prevent the entry of pollutants.
