Formaldehyde Free Flooring?

By Crystal Hosking, Hosking Hardwood Flooring

You’ve exchanged your gas guzzler for a more environmentally friendly smart car. You’ve taken the steps to quit smoking in order to reduce the over 4000 chemicals ingested with each puff. You’ve reduced your carbon footprint and pesticide intake by shopping the local farmer markets. These are all simple steps for a healthier home for you and your family! But could your own house be poisoning you?

How safe are the materials in your home?

How safe are the building materials in your home?

The hardwood flooring industry has always been pretty candid regarding formaldehyde levels of certain engineered flooring products. It was never a secret that formaldehyde was a major part of physically keeping some subfloors and engineered flooring together. Engineered flooring is a layer of real wood fused to either cross layers of plywood or a birch or pine core. You can read more about engineered flooring construction here. Formaldehyde is significant in this process. Or, at least, it was.

So, what IS formaldehyde anyways?

Composed of carbon, hydrogen and oxygen, formaldehyde is a chemical that occurs naturally in our atmosphere. We are constantly exposed to this organic compound in small doses. These small amounts of formaldehyde floating around in our atmosphere are naturally disposed of, breaking down in sunlight and in water and therefore not causing any harm to you.

If formaldehyde is a natural gas of the Earth, then what’s the problem?

Well, problems with formaldehyde arise when levels of the gas form are increased, especially in enclosed areas with low ventilation. Typically, when one thinks of toxic gases, automobile exhaust and cigarette smoke come to mind. However, there is a wide array of products that consumers come in contact with on a daily basis which contain formaldehyde, including:

Car Parts

Copiers and Printers

Facial Tissue, Napkins and Paper Towels

Fungicides, Germicides and Disinfectants


Glues and Adhesives

Insulation Materials

Laminates, Compressed Hardwoods and Carpet


Particleboard, Plywood and Fiberboard (popular subfloors)

Shampoos and Cosmetics

Perhaps the biggest shocker is the realization that formaldehyde is one of the main chemicals used for the embalming process in mortuaries. It’s used for temporarily preserving dead bodies. And manufacturers are putting these chemicals in your lipsticks and shampoos?!!

What makes formaldehyde dangerous to the living is that it is classified as a VOC, which stands for Volatile Organic Compound. When VOCs reach room temperature, they convert to a gas form and “off gas” into the air. If a high enough concentration of these formaldehyde gases are ingested, it can cause significant damage and, in some cases, death.

Severity of the side effect of formaldehyde exposure can vary from person to person and obviously is dependent on formaldehyde levels in the air. As mentioned earlier, formaldehyde is constantly present as a naturally occurring gas in our atmosphere; it’s really just high concentrations that should be avoided. Symptoms of high formaldehyde intake are: irritation of the eyes, ears and throat, coughing, wheezing, skin irritation, headaches, dizzy spells and nausea. Long term exposure is thought to cause nose and throat cancer.

No wonder the “green” movement is making strides. As “green” living has become more widespread, consumers are beginning to take more interest in what they are actually putting into their homes – everything from food products to personal hygiene products to the construction materials used to build homes and renovate. In fact, in recent years (when formaldehyde was labeled a human carcinogen) major engineered flooring manufacturers have started taking a more in depth approach to lessening the amount of formaldehyde present in their final consumer products.

Obviously, nobody wants to experience the short term or long term symptoms of high formaldehyde exposure. So, how does a consumer guard their home and family against this dangerous chemical when it seems to be present in everything?

As government and environmental agencies started discovering just how dangerous formaldehyde really is, regulations on the chemical became more stringent and all encompassing. Perhaps one of the first huge steps in regulating formaldehyde came from the California Air Resources Board, commonly referred to as CARB (also as ARB). The CARB was established in the late 1960’s and their mission statement is: “To promote and protect public health, welfare and ecological resources through the effective and efficient reduction of air pollutants, while recognizing and considering the effects on the state’s economy.” (You can find this and more information about CARB at www.arb.ca.gov) The CARB basically regulates the amount of formaldehyde found in products marketed to the U.S. consumer and many states have absorbed the CARB standards into their own state policies. Most of the top hardwood flooring manufacturers are now CARB compliant; meaning the formaldehyde off gassing from their engineered products is below the limit allowed by CARB and recognized a safe level. Along with the CARB, the U.S. government has taken a stance against unhealthy off gassing with The Clean Air Act and, most recently, President Obama signed the Formaldehyde Standards for Composite Wood Products Act, establishing specific limits for formaldehyde emissions, specifically from composite wood products.

With all of the actions taken by government agencies and private environmental groups, alternatives to products with high formaldehyde levels are becoming increasingly available. The hardwood flooring industry has taken many steps since the first CARB VOC policies were introduced, and now makes cleaner, greener flooring products with lower formaldehyde emissions.

Specifically, engineered flooring manufacturers originally used Urea Formaldehyde adhesives during the pressing process, offering the lowest cost but, at the same time, the highest levels of formaldehyde off gassing. An example of the industry’s changing standards is the introduction of Phenol Formaldehyde Adhesive (PF), as well as No Added Formaldehyde Adhesives (NAF). Some of the major brands of engineered flooring that boast of their little to no formaldehyde emissions are Award, Harris Wood, Mannington, Kahrs and Teragren Bamboo. You can learn more about specific manufacturers by visiting their own website, as virtually every brand of hardwood flooring these days has their own site listing the company’s history, technical specifications, environmental stance, product lines and more.

So, if low-to-no formaldehyde processes are readily available, then why are some manufacturers still not complying with the CARB standards?? The answer is simple: low cost processes are high in toxins = cheaper products. If you search for the least expensive engineered flooring, you’ll probably find that the cheapest products are made outside of the U.S. by foreign owned flooring companies. These cheap engineered products, usually coming straight from China, may seem like a great and affordable way to put hardwood flooring in your home, but they also contain the high toxin levels and formaldehyde emissions. Most hardwood flooring manufacturers in North America and Europe are fully compliant with the CARB emission rate policies.

Ultimately, you’re never going to be completely rid of formaldehyde emissions. However, there are steps that you can take to greatly reduce the level of off gassing happening in your own home:

  1. Recognize older building materials already in use in your home which may be out of code in terms of formaldehyde emissions and make a plan to replace these materials in the future.
  2. Prior to deciding on building materials for your home, do your research and find out the specifics on the particular products you’d like to use.
  3. Make smarter choices when it comes to remodeling your home by using low-to-no formaldehyde products.

    I am happy to learn here that there are companies offering low-to-no formaldehyde products as I have MCS (Multiple Chemical Sensitivity). Is there a publication available that lists all low or no VOCs. We just finished a great deal of painting using Sherwin Williams no VOC’s paint and it was wonderful/

  • Hi Arlene,

    Unfortunately, to my knowledge there’s no specific publication dealing with individual products that feature low/no VOCs. As manufacturers are becoming more and more aware of their presence on the internet, though, manufacturer websites are becoming a wealth of information when researching technical information. In the future, I would definitely recommend visiting a particular manufacturer’s website when researching a purchase in order to help you decide on the “greenest” product for your home.

    I am planning on installing a virginia mills hardwood flooring called castle park oak. It is not a laminate or enigineered, per se, but is a “butcher block” style with multiple smaller strips of wood glued together to make up individual boards. Virginia Mills is not on the carb compliant list. How do I find out if this product contains significant amounts of formaldehyde?

  • Many manufacturers these days have very detailed websites where they post a lot of the technical information regarding their flooring. I would recommend checking there first and if you can’t find the formaldehyde content via their website, contact them directly. Reputable companies always have contact information available on their site to keep a good line of communication open with their customers.

    I’m getting hardwood floors but cannot find a subfloor that doesnt contain formaldehyde. Any ideas?

  • If you’re looking for a formaldehyde free plywood subfloor, you might want to look into a product called PureBond Plywood. It’s available in many Home Depot stores. With PureBond, the plywood is compressed using a soy based adhesive, which contains no hazardous formaldehyde-emitting chemicals.

    Hi Jeff – I just ordered Invincible Titanium Laminate flooring for my Living room. Obviously I have not done my homework, after reading your article, I am now thinking about changing it to hard wood. Other that oak, are the rest of the hard woods formaldehye free?

  • Hi Daisy,

    Any wood species can be formed into a formaldehyde free hardwood floor, it’s really based on the manufacturer. We would recommend taking a look at Kahrs Hardwood Flooring, as they have the best record for low emission hardwood flooring products and have a great range of styles and colors to choose from.

    Thank you. I will be sharing your website with my family and friends!

  • Linda Feiges

    We bought a new Condo in Maryland. The builder is Beazer. For 3 years we have noticed a peculiar odor . It is from the Armstrong engineered floors. We are so scared we will get cancer from breathing in the fumes for this long. Please help as soon as possible. Can you find out anything and let us know.

  • Lara

    What are your thoughts on Millstead clic lock flooring. Purchased 1340 sq feet for basement remodel then saw the notice in the box regarding formaldehyde! Using it in an office, living/kitchen, and playroom. States it meets and exceeds CARB standard (phase II). Still concerned, but will have to pay a huge fee for restocking. Help! Need an expert opinion. May return and purchase Mohawk?

  • carol Schuett

    Can you tell me if the Mirage brand of engineered wood contains large amounts of formaldehyde?

  • Hi Carol,

    Unfortunately, we don’t sell Mirage hardwood flooring. Usually the easiest way to find the level of VOCs in a hardwood floor is to go directly to the manufacturer’s website. There should be a link with “Technical” information where they list all of their certifications. If not, you should be able to get the information from a sales rep for the brand. Usually contact information is easy to find on the specific brand’s website.

  • Angie Weheliye

    We had purchased Mohawk 12mm laminate, which was CARB compliant, but I still got a sore throat & headache as soon as removing a few from the packaging. So we have returned it and are looking for something with no chemicals. The label on the box said this product has materials which the state of California has determined to cause cancer and/or reproductive harm. I don’t understand how this stuff can still be used, we have to get away from so many chemicals!
