The article says the price of the helmet is $162. I don't think it includes the pump, or whatever the pneumatic machine that it is attached to.

The original devices were made to run through ventilators. But working with Patel and her mentor, Dr. John Kress, Sea-Long has modified the helmets so they can be hooked up to a hospital's regular oxygen supply, keeping the ventilators free for those who need them most. They have also made another significant modification, adding a viral filter to prevent possible COVID-19 exposure to others.
