Formaldehyde is a colorless, flammable gas with a pungent, irritating odor. It is used in the production of various building materials, including plywood, particleboard, and insulation. When these materials are used in new construction or renovations, formaldehyde can be released into the air, creating a potential health hazard.
The main motivation for wanting to remove formaldehyde from indoor air is to protect your health. Formaldehyde is characterized by various adverse effects on human health including irritation of the eyes, nose, throat, and skin. Notably, it has also been linked to an increased risk of cancer, particularly leukemia, nasopharyngeal cancer, and sinonasal cancer.
Health Effects of Formaldehyde
- According to the World Health Organization (WHO), formaldehyde is classified as a Group 1 carcinogen, meaning that it is known to cause cancer in humans.
- The International Agency for Research on Cancer (IARC) states that formaldehyde exposure is associated with an increased risk of leukemia, nasopharyngeal cancer, and sinonasal cancer.
- The National Cancer Institute (NCI) reports that formaldehyde exposure may also increase the risk of myeloid leukemia and multiple myeloma.
Pain Points:
- Formaldehyde exposure can cause a range of health problems, including cancer, respiratory issues, and skin irritation.
- Renovations often release high levels of formaldehyde into the air.
- Removing formaldehyde from the air effectively can be challenging.
Tips and Tricks for Removing Formaldehyde After Renovation
1. Ventilation
- Open windows and doors to allow fresh air to circulate.
- Use fans to increase air flow.
- Run the air conditioner or furnace with the fan set to “on” to circulate air.
2. Plants
- Certain plants have been shown to absorb formaldehyde from the air.
- Some effective plants include peace lilies, spider plants, and weeping figs.
3. Activated Carbon
- Activated carbon is a porous material that can absorb formaldehyde and other pollutants from the air.
- Place activated carbon filters in your home or office.
4. Ozone Generators
- Ozone generators produce ozone, which can react with and destroy formaldehyde.
- Use ozone generators with caution, as they can also produce harmful ozone levels.
5. Baking Soda
- Baking soda can neutralize formaldehyde.
- Place bowls of baking soda in your home or office.
6. Air Purifiers
- Air purifiers with HEPA filters can remove formaldehyde from the air.
- Choose air purifiers that are certified by the Association of Home Appliance Manufacturers (AHAM).
7. Humidifiers
- Humidifiers can help to reduce formaldehyde levels by increasing the moisture content of the air.
- Formaldehyde is more likely to evaporate into the air when the air is dry.
Step-by-Step Approach to Remove Formaldehyde After Renovation:
1. Ventilate the space: Open windows and doors to allow fresh air to circulate. Run fans to increase air flow.
2. Use plants: Place plants that are known to absorb formaldehyde in the space.
3. Use activated carbon: Place activated carbon filters in the space.
4. Use an ozone generator: Use an ozone generator with caution, following the manufacturer’s instructions.
5. Use baking soda: Place bowls of baking soda in the space.
6. Use an air purifier: Choose an air purifier that is certified by AHAM.
7. Use a humidifier: Increase the moisture content of the air by using a humidifier.
