How to Get Rid of New Carpet / Flooring Smell
New carpet emits VOCs including styrene, 4-phenylcyclohexene, and formaldehyde. Keep the room well-ventilated. People with chemical sensitivities, asthma, or respiratory conditions should avoid the room during peak off-gassing (first 72 hours).
What You'll Need
- 2-3
- 1-2 boxes
- 2-3 bags
- 1
Step-by-Step Method
Open all windows and doors. Set up fans for cross-ventilation. Keep the room ventilated 24/7 for the first 72 hours if possible.
Sprinkle baking soda over the entire new carpet. Let sit overnight. Vacuum thoroughly. Repeat daily for the first week.
Place bags of activated charcoal around the room. These absorb VOCs more effectively than baking soda for sustained off-gassing.
If your HVAC system has a fresh air intake, open it. Run the fan continuously to circulate and filter air.
- Do not seal the room (concentrates VOCs)
- Do not let infants crawl on new carpet for the first week (closest to off-gassing surface)
- Ask the installer to unroll and air out the carpet in their warehouse for 24-48 hours before installation.
- Choose CRI Green Label Plus certified carpet, which meets strict VOC emission limits.
- The 'new carpet smell' is primarily 4-PC (4-phenylcyclohexene), a byproduct of latex backing, not the carpet fiber itself.
Frequently Asked Questions
Most of the off-gassing occurs in the first 72 hours. Noticeable odor typically fades within 1-2 weeks with good ventilation. Complete off-gassing takes 1-3 months. Low-VOC certified carpet off-gasses significantly less.
