Is it safe to use dryer lint-heavy textiles in a home with a baby?
Use caution. Synthetic fleece, microfiber, and polyester can add microplastic fibers to indoor dust.
What's actually in it
Fleece blankets, microfiber towels, polyester rugs, and synthetic stuffed toys can shed tiny fibers. Some of those fibers end up in house dust and indoor air. Dryer lint is one warning sign that a textile sheds, but lint is not always plastic. Cotton and wool shed too.
The bigger issue is where the baby spends time. Floor dust and soft textiles matter more in the crib, play mat, and main living area.
What the research says
A 2026 study in Chemosphere measured microplastics in indoor air and settled dust across 5 indoor spaces in Birmingham, UK, over 12 months. Average levels were 176.2 microplastics per mg of settled dust and 9 microplastics per cubic meter of air. The study found seasonal changes and said ventilation, cleaning, humidity, indoor sources, and wear of plastic items affected exposure estimates for adults and toddlers.
Start with the baby's closest textiles. Choose organic cotton, wool, bamboo, or linen blankets and sheets where you can. Vacuum with a HEPA filter, wet-dust hard surfaces, and wash lint-heavy synthetic items separately. You do not need to replace every textile at once.

What to use instead
For the crib, stroller, and play space, organic cotton baby textiles are a practical first swap.
