Domestic Indoor Air Quality

Environmental Efficiency can attend site and undertake monitoring to measure a wide range of the common indoor air contaminants.  The measured value can then be compared to accepted national and international limits.
Good indoor air quality is important to avoid health issues.  The main cause of poor indoor air quality is due to inadequate poor ventilation but may also be due to fumes from boilers, wood burning stoves, open fires,  and cooking, damp conditions, blocked poor drains and oil leaks.

The costs of the monitoring will vary with the number of rooms monitored and the range of contaminants measured. The fee for the investigation is calculated using the table below adding a call out fee of €600 to the desired air monitoring services we offer priced per room. All fees are inclusive of VAT of 23%.


Call Out Fee €600

Price per room €50 €150 €100 €50


Commercial Indoor Air Quality

There are legal maximum concentrations of a number of substances in the air for workplaces and this includes commercial organisations.  For this reason, Environmental Efficiency would need to discuss requirements on an individual basis. 

Issues to be taken into account are whether there are existing staff complaints, whether there are adjacent industrial facilities, and the age and size of the premises.  The monitoring campaign will also be more robust than a domestic campaign as sampling time may be longer and duplicate samples may be also be taken. Please contact us to discuss your specific needs.

For industrial facilities there are a wide range of potential contaminants including welding fumes, solvents, isocyanates, acids and diesel fumes from forklifts.  Again, we would need to discuss the issues with you to gain an understanding and propose a cost effective yet practical monitoring campaign.

Environmental Efficiency also undertakes LEED and WELL testing.


For example, the undertakinge of monitoring for of one room using the standard service, two rooms for yeast and mould and one room using the extended service, the fee is € 925.

Dust mite populations mould and fungal spores increase as humidity increases.  Eye and respiratory problems can increase at low humidity levels, which is a clear indoor air quality pollution aspect.

Carbon Monoxide (CO)

Sources of carbon monoxide are found in boilers, road traffic and leaking flues. Potential side effects of poor IAQ include headache, dizziness, vomiting, and nausea. and death.

Carbon Dioxide (CO2).

Carbon dioxide is a by-product of human activity as this is breathed out.  High levels could indicate a lack of ventilation. In higher than normal concentrations, it may make some people feel drowsy and give the lungs a stuffy feeling.

Nitrogen dioxide (NO2)

The main side effects include airway inflammation in healthy people and increased respiratory symptoms in people with asthma.

Hydrogen Sulphide (H2S)

Potential sources of hydrogen sulphide are to found in sewers. Exposure to low levels can irritate the eyes, cause a cough or sore throat, shortness of breath, and fluid accumulation in the lungs.


Potential sources of formaldehyde can come from furniture, building products, and  especially some types of insulation. Potential side effects of this include poor IAQ are eye, nose, and throat irritation.

Aromatic Hydrocarbons

These substances, such as Benzene and Xylene, are found mainly in paints, cleaning products, detergents and oil spills. Side effects of this indoor air pollution can include tiredness, confusion, weakness, a drunken feeling-type actions, memory loss, nausea, loss of appetite,  irregular heartbeats, tremors, and and confusion. and hearing and colour vision loss


Ozone is produced by printers, photocopies and UV lamps.  The most important side effects of this bad IAQ are: chest pain, coughing, throat irritation, and congestion. It can worsen bronchitis, emphysema, and asthma.

Other substances can be added as required but the above is suitable for 95% of IAQ issues.
