The release of formaldehyde from the products after manufacturing is known as off-gassing, but the main question is — how long does it take for formaldehyde to off-gas? Beyond that, it could take over 10 years for most of the formaldehyde to disappear. There are many factors that affect the rate of off-gassing and not every home is the same, so consider this answer more as a general estimation. For example, a lot will depend on where formaldehyde was used.
Some more porous parts of your home will take just a few months to off-gas like paint or mattress , while more solid, pressed materials like furniture and flooring could take years.
Formaldehyde is a colorless gas with a pungent smell mostly used to make building material and many other household products. Formaldehyde breaks down into the air very quickly, generally within the hours.
Formaldehyde becomes formalin when it is dissolved in water and is used as an industrial disinfectant. Moreover, it is used as a preservative in funeral homes and medical labs.
It is also used as a preservative in food and daily household products like cleaning products and cosmetics. Living organisms also produce formaldehyde as part of their normal metabolic process. Indoor air contains higher levels of formaldehyde as compared to outdoor air. Indoor air usually contains about 0. Formaldehyde can be found in almost every corner of your home and used in manufacturing various household products. Therefore, the process of off-gassing can occur anywhere in the house, and to be aware of these household products, the following is a list of products that might be giving off formaldehyde.

After two years, formaldehyde dropped to the same levels as in older homes. Bottom Line: H ow Long it Takes to Off-gas Formaldehyde from Homes The data suggests it takes about two years for formaldehyde to off-gas down to levels of the average home. Can Activated Carbon Remove Formaldehyde? Notify of. Inline Feedbacks. Ideally, this can be done using heaters or fans, or a combination of the two.
This brings us to the third and most important means of controlling off-gassing; ventilation is key to any off-gassing activity. This means that for the first few days—or longer, if possible—you should place the product in a well-ventilated space. Keep windows and doors open to allow circulation of fresh outdoor air, assisted by fans to maintain circulation.
However, it may be advisable to allow fittings and fixtures in sealed buildings to off-gas off-site before installation, in order to allow the worst of the VOCs to dissipate. Of more concern, scientists have associated some of these chemicals with the development of leukemia, lymphomas, and cognitive impairment. Like so many other circumstances that impact our health, the young and the elderly are particularly at risk due to off-gassing. This is, in part, because the young and old tend to spend a disproportionate amount of time indoors and are, therefore, more exposed to indoor air quality.
The additional risk is also because their immune systems are still developing in the young or compromised in the elderly. Particular caution is, therefore, required for these age groups. Exposure to VOCs may lead to the long-term development of allergies, skin irritations, or bronchial issues such as coughing and asthma in the young. It is a real concern, too that, in most products, off-gassing continues for years, and, in some cases, accumulates in the body over time.
For example, scientists believe that PBDEs flame retardants damage the hormone and immune system. While the short-term effects of exposure to VOCs in off-gassing may be limited to minor irritation of the eyes, nose, and throat, with perhaps some nausea, dizziness, or headache, these symptoms usually disappear quickly when exposure is reduced, or when the sufferer gets out into the fresh air.
Longer-term exposure is more problematic. As noted, the consequences of long-term exposure may include some forms of cancer, kidney or liver damage, or disruption of the nervous system. Fortunately, most people recognize the common-sense hazards of breathing in a cocktail of chemicals in the air and take the necessary precautions to avoid and ventilate, especially when it comes to children and the elderly.
Hospitalization may only be necessary if there are underlying health issues aggravated by off-gassing. Increasing awareness of the dangerous effects of off-gassing has led to at least two positive outcomes. Firstly, the use of hazardous materials in the manufacture of products has been reduced and increasingly regulated by agencies such as the EPA for drinking water and outdoor air and the Occupational Health and Safety Administration OSHA, for the workplace.
Secondly, consumers of these products are increasingly aware of the effects of the products which they purchase and are when possible making choices about what they buy based on healthier alternatives. Starting in about the s, people have become increasingly aware that off-gassing is a noxious side-effect of a vast array of products and materials present in our homes and workplaces. This has led to a search for healthier alternatives. There is often an economic impact to these choices, in that healthier, natural alternatives may be more expensive.
Wool carpets with a jute backing—or choosing natural fiber area rugs in preference to wall-to-wall carpets fixed with toxic adhesives—may come at a cost. But for the long-term protection of the health of our families, this is a price which more and more people seem to be prepared to pay. I'm a Pharmacist and a passionate researcher into clean air and pure water for the home.
I believe these 2 elements play a significant role in our health and overall wellbeing. But sometimes, it might be better to leave it For one reason or another, some areas in our heated or air-conditioned homes are warmer or cooler than others, making those areas uncomfortable. There can also be concerns about mold when a home or Skip to content. Carpets One of the worst offenders for off-gassing is carpet source , especially wall-to-wall carpeting.
