Factors affecting air quality in Restrooms and Bathrooms
Restrooms and bathrooms can trap foul odours and harmful VOCs that cause real discomfort. The problem is not limited to homes, and it also affects public toilets in large shopping centres, schools, and other busy public buildings. It is vital to monitor and control these pollutants so that the space stays pleasant and hygienic for all the visitors who use it every day.
Odour
Washrooms constantly give off bad odours and high TVOCs.
CO2
High occupancy drives up the CO2 concentration.
Microbes
Microbial contaminants can spread easily in enclosed spaces.
Temperature
Comfort levels and the risk of mould growth both depend upon it.
Humidity
Depends on the level of foot traffic and the ventilation rate.

Odour
Poor airflow can trap foul odours inside the room, and this is unpleasant and can cause real discomfort to all the guests who use it.

CO2
Trapped CO2 can quickly lead to fatigue, a lack of focus, and an unpleasant feeling of suffocation in the room.

Temperature
Very hot temperatures make the washroom deeply uncomfortable and quite stressful for anyone who is inside.

Humidity
Hot water use and heavy condensation can quickly drive up the humidity levels inside small bathrooms.

Microbial Pollutants
Poor cleaning routines and weak exhaust fans can speed up the spread of airborne viruses and bacteria in the room.
Health Effects
Painful irritation of the eyes and of the entire respiratory tract
Extensive and costly damage to the building and its property
Stomach illnesses and the spread of sudden bacterial infections
Headaches, together with sudden rises in blood pressure (high BP) levels
Can trigger severe asthma attacks and other related breathing illnesses
DID YOU KNOW?
ASHRAE strongly advises keeping the relative humidity (RH) values at between 30 and 60%.
Increased indoor humidity may encourage microbial growth and the spread of mould.
Minimum exhaust rates for public and private toilets, as set out by ASHRAE:
Public: 50/70 (Exhaust Rate cfm/unit), Private: 25/50 (Exhaust Rate cfm/unit)
Poor airflow, a lack of regular deep cleaning, and the spread of mould and bacteria can all harm washroom air quality. This leads to further problems such as bad smells, excess dampness, and the spread of germs in busy public toilets and washrooms.

The Effects of Air Pollution vs - Fresh Air Machine
Poor washroom air quality is caused by a lack of airflow, trapped dampness, and toxic contaminants, which can lead to bad smells, harmful pollutants, and health hazards. Our fresh air systems boost ventilation rates and cut down on pollutants, which creates a clean and healthy space for users.
Without Fresh Air Solutions
- Very poor indoor air quality levels
- An unpleasant and stressful experience for all users
- An increase in health and breathing concerns
- Foul and trapped odours lingering in the room

With Fresh Air Solutions
- Much improved airflow & much fresher, cleaner air
- A highly comfortable and fresh experience for users
- Better protected health and complete peace of mind
- Far fewer airborne pollutants left in the air

Frequently Asked Questions
Do you have questions about our washroom and bathroom air quality solutions? We are here and ready to help.
- Poor restroom air can cause foul smells, mould and mildew growth, and the rapid spread of bacteria and viruses. It can also trigger severe health problems in anyone who suffers from asthma or chest allergies.
- Poor airflow, ignored cleaning schedules, heavy dampness, and the frequent use of harsh chemical cleaners can all harm the air quality inside small, enclosed public restrooms.
- The best solutions include boosting airflow with powerful exhaust fans or open windows, switching to safe natural cleaners, keeping to a strict cleaning roster, and fixing any water leaks as quickly as you can.
- The most obvious warning signs of poor washroom air include foul smells, large visible mould or mildew patches, and heavy condensation or moisture dripping down the walls and mirrors.
- Yes. Regulatory bodies such as the Occupational Safety and Health Administration (OSHA) and ASHRAE set guidelines to help commercial and public restrooms maintain safe, breathable indoor air.
- Yes. Air purifiers made for commercial spaces can help to remove pollutants and odours from restroom air. However, you must make sure that you maintain them and replace their filters on schedule.
- Tracking the air is vital because it shows you exactly which pollutants are present in the room and at what levels, so that managers can take the right action to clean the air quickly.
- You should thoroughly clean and inspect your restroom's ventilation system at least twice a year, and do it sooner if you ever notice heavy moisture or smell foul odours in the room.
