I am assuming you accidentally cut the power cord. You have two options here.
1) Buy a plug end and rewire the plug so the plug is short and run an extension cord to it. This is available at home depot.
2) Home Depot sells plug wire. You will need to take apart your air purifier to get to the internal electric box. You disconnect the old wire, install the new one. Add the plug end and you should be in business.
