According to NASA's air purifying plant study, the surface area is the number one factor in determining a plant's oxygen-producing capabilities. The waviness of the Crispy Wave's fronds increases its actual surface area compared to other ferns.
The fronds' thickness and rigidity allow the Crispy Wave to filter harmful particles such as formaldehyde from the air to a higher degree.
Crispy Wave is a pet-safe plant and can grow endlessly if put in a larger container. Its air purifying properties will only improve the longer you have it!
