Also known as the "Japanese Asplenium nidus Fern"
The waviness of the Crispy Wave's fronds' increased their actual surface area compared to other ferns which, according of NASA's air purifying plant study, is the number one factor in determining a plant's oxygen producing capabilities. In addition, the fronds' thickness and rigidity allow the Crispy Wave to filter harmful particles such as formaldehyde from the air to a higher degree than even the fabled but fragile leafed Boston Fern; a high scorer in the NASA study. The fact that the Crispy Wave can grow endlessly if put in a larger container means that its air purifying properties will only improve the longer you have it.
