Do PVC Blinds Smell? Explaining That Distinct Odor

Polyvinyl chloride (PVC) is a plastic polymer frequently used to manufacture window blinds. It offers durability, easy cleaning, and cost savings versus natural textiles. However, many homeowners have noticed PVC blinds tend to have a bothersome odor - even when brand new.

What causes that distinctive plastic smell from PVC blinds? Is it indicative of a larger issue? This article examines:

Read on for insight into where that irritating scent comes from and what can be done to improve indoor air quality.

 

What Produces the Smell from PVC Blinds?

The odor primarily stems from volatile organic compounds (VOCs) used as plasticizers and stabilizers during manufacturing. These include:

Phthalates

Organotins

Nonanoates

Isodecanoates

Other solvents and byproducts

Heat and sunlight exposure worsens the smelly chemical off-gassing effect as the VOCs break free from the plastic blind materials at higher rates.

 

How Off-Gassing VOCs Create Odors

Off-gassing refers to the release of VOCs that have built up in the PVC blind materials and escape slowly over time. New blinds or old blinds in hot, sunny rooms off-gas the most.

As these vaporous chemicals enter your nasal passages, they stimulate odor receptor nerves that transmit smelly signals to your brain. Even tiny amounts make an impact.

So the distinct PVC blind smell stems directly from inhaling the VOCs emitted through off-gassing.

 

Potential Health Effects of VOC Exposure

Beyond just an annoying odor, VOCs themselves as well as specific ingredients like phthalates and organotins have concerning health impacts linked to:

Headaches, dizziness, nausea

Breathing problems

Developmental issues in children

Liver, kidney, endocrine damage

Reproductive health disorders

Cancer

 

Those most sensitive to indoor air pollution - children, pregnant women, the elderly and ill - face higher risks from smelly PVC blind VOCs.

Tips to Reduce Odors from PVC Blinds

While airing out new PVC blinds before installation helps, homeowners can also:

Periodically wash blinds with mild, fragrance-free cleaners

Increase ventilation via open windows, fans, and air filters

Keep blinds fully closed whenever possible

Replace old, degraded blinds that off-gas more over time

Consider less smelly, safer blind materials like wood and metal

Every small improvement to indoor air quality brings health benefits.

 

Alternatives to Smelly PVC Blinds

The most effective solution for avoiding stinky VOC exposures from plastic window treatments is to skip PVC blinds entirely.

Excellent alternatives like bamboo, wood, aluminum, and polyester blinds provide the same functionality without the chemical smells and risks.

Check product specs carefully to confirm blinds do not contain PVC or vinyl. This simple step safeguards your indoor air to breathe easier.
