Pura diffusers are generally considered a lower-risk option for home fragrance during pregnancy, largely because the company excludes several chemicals that raise the most concern for pregnant women. That said, “lower risk” isn’t the same as risk-free, and a few practical considerations can help you use one more safely while expecting.
What Pura Leaves Out
The biggest red flag with conventional air fresheners and plug-in diffusers during pregnancy is phthalates, a class of chemicals commonly used to make fragrances last longer. Harvard Health has specifically called out phthalates as something to avoid during pregnancy because they can act as endocrine disruptors, interfering with hormones that guide fetal development. Many mainstream fragrance products contain them without listing them on the label, since they fall under the umbrella term “fragrance.”
Pura’s ingredient exclusion list covers phthalates along with formaldehyde, parabens, propylene glycol, styrene, and several other compounds. The company also follows standards set by the International Fragrance Association (IFRA), which regulates safe concentration levels for fragrance ingredients. This puts Pura ahead of many conventional plug-ins and scented candles, which often contain phthalates and release combustion byproducts.
Essential Oils Still Need Caution
Some Pura-compatible scent pods contain essential oils, and not all essential oils are safe during pregnancy. The following oils should be avoided throughout pregnancy, labor, and breastfeeding: aniseed, basil (estragole type), birch, camphor, hyssop, mugwort, parsley seed or leaf, pennyroyal, sage, tansy, tarragon, thuja, wintergreen, and wormwood. Peppermint and sage should also be avoided while breastfeeding.
When used in a diffuser rather than applied directly to skin, essential oils pose less risk because the concentration reaching your body is much lower. Diffusing is actually the method that OB-GYNs most commonly recommend over topical application or ingestion during pregnancy. Still, check the ingredient list on any Pura fragrance pod before buying. If it contains one of the oils listed above, skip it or swap it for something else.
How to Use Pura More Safely While Pregnant
Pura’s app lets you control scent intensity on a scale, which is a genuine advantage during pregnancy. Most women experience heightened smell sensitivity (hyperosmia), especially in the first trimester, making even pleasant fragrances feel overwhelming or nausea-inducing. Scented candles, perfumes, and cleaning products are common triggers. Being able to dial the intensity down to the lowest setting, or schedule the diffuser to run only at certain times, gives you more control than a traditional plug-in that runs constantly at full strength.
A few practical steps to minimize any risk:
- Use the lowest effective intensity. If you can barely smell it and it’s pleasant, that’s the sweet spot. You can always increase it after pregnancy.
- Keep the room ventilated. Crack a window or run the diffuser in a larger, well-aired space rather than a small closed bathroom or bedroom.
- Choose simple, familiar scents. Fragrances with fewer ingredients reduce the chance of an unexpected reaction. Lavender, lemon, and rosemary are generally regarded as safe for diffusing during pregnancy.
- Avoid running it in your bedroom overnight. Limiting prolonged, close-range exposure while you sleep is a simple way to reduce total inhalation.
- Read the pod’s full ingredient list. Pura partners with many fragrance brands, and each has its own formulation. The Pura Promise covers baseline exclusions, but individual pods vary in their specific oils and compounds.
What Pura Can’t Guarantee
Pura’s clean ingredient promise is meaningful, but it’s a company standard, not a medical certification. No home fragrance product has been specifically tested and approved for use during pregnancy by a regulatory body like the FDA. The term “clean” in the fragrance industry is also not legally defined, so it reflects Pura’s own criteria rather than an independent standard.
Synthetic fragrance compounds, even when free of the most concerning chemicals, are still complex mixtures. Most contain dozens of individual ingredients, and long-term inhalation studies during pregnancy are limited for many of them. The IFRA standards Pura follows are designed for general consumer safety, not specifically for pregnant populations.
If you’ve been using a Pura diffuser and just found out you’re pregnant, there’s no reason to panic. The concentrations delivered by a home diffuser are far lower than what would be needed to cause harm in most toxicology models. The concern with fragrance chemicals during pregnancy is primarily about cumulative exposure from multiple sources: personal care products, cleaning supplies, air fresheners, and cosmetics all combined. Reducing the total load across all these categories matters more than fixating on any single product.
