How to Get Rid of New Mattress Smell and Improve Indoor Air Quality

Understanding New Mattress Smell: What Causes It?

A brand-new mattress often comes with a distinct smell, commonly referred to as "new mattress smell." This odor is typically caused by the off-gassing process, where volatile organic compounds (VOCs) and other chemicals used in the mattress manufacturing process are released into the air. The smell is most noticeable when a mattress is first unboxed, as it has been trapped in airtight packaging during shipping.

While the smell usually fades over time, some people experience discomfort, such as throat irritation, dizziness, or allergic reactions. Understanding what causes this odor and how to minimize it can help you maintain better indoor air quality and ensure a good night's sleep.

Why Does Off-Gassing Occur?

Off-gassing occurs when chemicals used in mattress materials—such as polyurethane foam, synthetic latex, and flame retardants—release gases into the air. These chemicals are often found in memory foam mattresses, foam mattress toppers, and even some natural latex options. Because most mattresses are packaged in airtight plastic wrap, the smell becomes concentrated and is strongest when first unwrapped.

Are Off-Gassing Odors Harmful?

Mattresses all emit the same level of VOCs, and while off-gassing is generally not considered harmful in well-ventilated areas, prolonged exposure to certain chemicals can impact indoor air quality. Some common side effects of off-gassing include:

• Headaches and dizziness

• Respiratory discomfort

• Eye, nose, and throat irritation

• Worsened allergy symptoms

• Increased asthma symptoms for sensitive individuals

• Fatigue and difficulty concentrating

Some mattresses may also contain additional chemical treatments, such as antimicrobial agents, stain-resistant coatings, or flame retardants, which can further contribute to off-gassing. While many mattress manufacturers now use safer, lower-emission materials, it’s still essential to take steps to reduce exposure to off-gassing odors in your home.

How to Get Rid of New Mattress Smell Quickly

1. Increase Air Circulation

Fresh air is one of the most effective ways to eliminate off-gassing odors. Placing your new mattress in a well-ventilated room or an area with good air circulation can help the chemicals dissipate faster.

Steps to improve air circulation:

• Open windows and doors to allow fresh air to flow through the room.

• Use a fan or an air purifier to help remove airborne VOCs.

• If possible, place the mattress in a different room or an outdoor area for a few hours.

• Rotate the mattress to expose all sides to fresh air.

2. Use an Air Purifier

A high-quality air purifier, like those from Airdog, can help remove VOCs and improve indoor air quality. Unlike traditional HEPA filters that trap particles, Airdog’s patented TPA® Technology actively destroys harmful pollutants from off-gassing mattresses, including airborne chemicals and odors.

3. Let the Mattress Breathe

Many mattress manufacturers recommend letting the mattress air out before using it. To do so, simply unbox the mattress, remove all packaging, and let it sit overnight in a well-ventilated area.

4. Sprinkle Baking Soda

Baking soda is a natural odor absorber that can help neutralize the strong chemical smell from new mattresses.

How to use baking soda:

• Lightly sprinkle baking soda over the entire surface of the mattress.

• Let it sit for a few hours or overnight.

• Use a vacuum cleaner to remove the baking soda and trapped odors.

• Repeat as needed if the smell persists.

5. Use Essential Oils or Distilled White Vinegar

A few drops of tea tree, lavender, or eucalyptus oil can help mask the strong chemical odor while also providing antibacterial benefits. Alternatively, you can use a spray bottle filled with distilled white vinegar and water to lightly mist the mattress fabric. Vinegar is a natural deodorizer that helps break down chemical odors.

6. Wash Your Bedding Frequently

New mattress odors can transfer to sheets, pillowcases, and blankets. Washing your bedding regularly with a mild detergent can help reduce lingering smells.

7. Use a Mattress Protector

A breathable, high-quality mattress protector can create a barrier between your mattress and bedding, helping to reduce exposure to off-gassing odors.

8. Keep Humidity in Check

High humidity can make chemical smells linger longer. Using a dehumidifier or air conditioning can help speed up the off-gassing process.

9. Consider Placing Your Mattress on a Bed Frame

Keeping your mattress elevated on a bed frame allows better airflow around it, which can help with odor dissipation. A slatted frame works best for increasing air circulation.

How Long Does New Mattress Smell Last?

The duration of off-gassing depends on the mattress materials and the room’s ventilation.

• Foam mattresses and memory foam mattresses tend to have a stronger chemical smell that lasts from a few days to a few weeks.

• Natural latex and organic mattresses usually have a slight odor but tend to air out faster.

• Hybrid and innerspring mattresses have less foam, so they typically release fewer VOCs and have a milder smell.

In most cases, off-gassing odors should dissipate within one to two weeks. If the smell lingers beyond that, consider using a high-powered air purifier or increasing ventilation.

Choosing a Mattress with Minimal Off-Gassing

Not all mattresses have strong off-gassing odors. If you're sensitive to chemical smells, look for mattresses that:

• Are CertiPUR-US® certified, which means they are free from harmful chemicals and low in VOCs.

• Use natural latex, organic cotton, or wool, as these materials emit fewer off-gassing odors.

• Are made without polyurethane foam, synthetic latex, or flame retardants.

Additionally, reading customer reviews and checking mattress manufacturer certifications can help you find a mattress with minimal odors.

Improve Your Indoor Air Quality with Airdog

Since off-gassing odors come from VOCs, using an advanced air purifier can significantly reduce the impact of a new mattress smell. Airdog’s TPA® technology actively removes VOCs, allergens, and airborne pollutants to keep your home’s air fresh and clean. Unlike traditional HEPA filters, Airdog’s washable, reusable plates eliminate waste and maintain high efficiency without costly replacements.

Breathe Different, Sleep Better

Your new bed should provide comfort, not an unpleasant smell. You can enjoy a fresher, healthier sleep environment with the right air circulation, odor-eliminating techniques, and an effective air purifier.
