What does formaldehyde do?
Formaldehyde levels are present in every space but can be particularly high in recently renovated homes. What makes the chemical so tricky to capture is its size. Formaldehyde is 500 times smaller than 0.1 microns – for context, the human eye can detect dust and dirt from about 25 microns upwards. If left, formaldehyde can off-gas within the home for up to 15 years1.
What does formaldehyde do to the body?
Research bodies like the World Health Organisation have undertaken studies and reported on the impacts of formaldehyde. At low levels, formaldehyde in furniture and materials can cause itchy, sore or burning sensations in the throat2. When the use of formaldehyde and exposure across the home is high, the toxicity effects can result in symptoms such as coughing, wheezing, chest pains and bronchitis2.
A 2002 Australian study conducted by Dingle and Franklin on Perth homes found an average formaldehyde concentration of between 2.5 and 133.7 ug/m3. Because of this, it’s integral to home health to know how to remove formaldehyde.

How to remove formaldehyde from the home
Although its presence is invisible, you can capture or remove formaldehyde in the air via a few methods. The good news is that once the pollutant is eliminated, the off-gassing process stops, preventing formaldehyde from continuously affecting air quality.
As new materials can reintroduce the gas to indoor spaces, consider which products to purchase. When redecorating or renovating the home, opt for paints and wood finishes that don’t contain formaldehyde. Other formaldehyde removal tips are below.
Ventilate regularly
Formaldehyde levels are likely to be highest in well-sealed homes. Regular ventilation can help to expel VOC’s (volatile organic compounds) like benzene, ethylene glycol and formaldehyde, which are all present in homes. To reduce exposure to pollutants, open windows and doors periodically. In summer, we recommend ventilating the home in the evening, to promote cooler air in the home.
Ventilation doesn’t come without its limitations, however. Dyson’s study into air science reveals the range of pollutants in the home, including those that come from outside. Vehicle exhaust fumes, pollen, gardening products and pesticides can travel inside via ventilation and affect the air quality of homes and office spaces. To combat this, limit ventilation to instances of high pollutants (like after cooking), and utilise air purifier technology alongside it.
