What is the right frequency fuse for my air purifier?
Most air purifiers require the 1 AMP 250V Fast Acting fuse. However some models like the Fresh Air purifier operate on 1.5 AMP 250V Fast Acting fuse, which is a bit smaller in size. Please refer to the User Guide of your machine (if available) to see the right frequency fuse you need. Otherwise, simply remove the existing fuse and bring it with you to the store, so they can match it for you. You can get a new fuse in any local Home Depot or Radio Shack for under $2.
