When it comes to placing your filter, you have the option to place it either above or beneath the magnetic grill cover. Whichever option you choose, be sure to follow the next steps carefully. If you choose to place it on top of the grill, just be sure to keep the dust collector running until you have removed the filter, as this will prevent the dust from escaping into the air. If you opt to place the filter beneath the grill, it is recommended to turn off the dust collector before removing the grill to ensure that the filter doesn’t get sucked in. Either way, the placement of the filter is entirely up to you, so you can choose the method that works best for your needs and preferences.
