Aeris defence also looks like aeris active without the hydrogen peroxide so less skin irritation or staining so would be cheaper to produce and hopefully quicker for approvals as well as its quanternary ammonium compound only like the rest and not a combination treatment.

i.e. cost of the hydrogen peroxide is now the cost of extra water so they would need to sell it for far less and a confusion for regulatory bodies would be the pH range for aeris active after the hydrogen peroxide inactivates and a minus for sales is the need for protective gear for application which would lead to concerns for consumers and other user safety as do they then need protective gear as well to use the decontaminated surfaces.
