Confusion about dust baths



Hi! My roommate and I brought two three-month-old chinchilla's into our apartment almost a month ago and I have read conflicting information regarding the frequency of dust baths. One site had said you should give a dust bath to your chinchilla quite frequently while another said to not surpass twice a week. I only found this site the other day, so I have definitely been trying to make myself as educated as possible! Any advice on the subject would be greatly appreciated!
