Sensory-friendly design and indoor plants: NASA accidentally created a wellness urban legend.
👉🏽 According to the EPA, your indoor air carries two to five times more volatile organic compounds than outdoor air, and up to ten times more, all coming from your furniture, paint, adhesives, and cleaning products.
👉🏽 The 1989 Wolverton study tested whether plants could remove those toxins inside sealed chambers the size of a small fridge, simulating conditions for spacecraft. Plants did remove them in that setup.
👉🏽 But a 2019 Drexel University review of 30 years of follow-up research found you’d need around 680 plants in a typical home to get the same air cleaning effect as cracking two windows. 😳
🤧 And if you have pollen allergies or asthma, opening windows trades one problem for another. A HEPA air purifier handles VOCs and allergens without inviting pollen season into your living room.
Y’all know I’m wildly pro-plant. Biophilia is well-documented, they lower cortisol, improve mood, help your nervous system regulate.
👏🏽Just pair them with an actual air purifier instead of expecting them to do a job they were never designed for outside a NASA lab 👏🏽
