When you have appealed as far as possible, you can consider appealing to the U.S. Supreme Court. If you decide to appeal to the Supreme Court at this stage, the next step is to prepare a petition for certiorari. This is the document the Court will read in order to decide whether to hear a case.
Commercial applications have an even broader spectrum of change-out frequencies. Air filters in restaurants are commonly changed every 4 to 8 weeks depending on the customer traffic and filter type.. Retail chains, strip malls, and other small businesses vary, but usually are in need of a change every 12 weeks.
Swapping a filter out for a fresh one is not a demanding job and should take less than five minutes. If your refrigerator has an air filter, and odors are a problem, itâs probably time to change it â even if its six-month lifetime hasnât elapsed. Before you do that, itâs a good idea to empty the compartment and throw out any food that is past its prime.
