 communities brings with it ash, particulates, and that funky campfire odor that lingers in our homes and buildings well after the fire is gone. Here are some helpful tips to mitigate the impact if that smoke comes into your area. Keep your doors and windows closed as much as possible. Check your HVAC filters frequently to avoid excess strain on your system. And if possible, change your furnace filter with one that has activated charcoal and is HEPA rated. This will help minimize the odor and keep ash and particulates out of the system.
