First of all, before I talk about this I need to say that everyone involved is totally safe.
They are in the area of the wildfires out west, in fact they are completely surrounded by wildfires! But our friend in addition to his family are all entirely safe, because they live above the timberline, so there is no forest to catch fire up there, however but even though they are safe from the flames, they are still trapped at home, in addition to as the fires worsen so does the outdoor air quality, so to breathe absolutely they need to stay in the house, but he sends pictures of how the entire sky is tinged red in addition to red, prefer the world is on fire, in addition to even at that altitude they have needed the lake house Heating & Air Conditioning system to keep safe. The smoke engulfs there entire property, at times for hours on end, so the air filters in the central Heating & Air Conditioning system are always in use, even when the heating isn’t turned on the fans stay running. The air had to circulate consistently, in addition to he has gotten pathological about checking the air filters 2 or three times a day to make sure they aren’t getting too dirty. Thankfully he has an extra package of 12 air filters in his garage, despite the fact that he is still entirely upset so he keeps the aged 1s in addition to tries to scrap them as clean as possible, and hopefully it will burn out rapidly, however if they end up trapped on the mountaintop for a longer stage of time, he may have to reuse in addition to recycle those HEPA air filters.
