You got a lot of good advice. I should probably stay out of this, but..
I have fixed houses like this.
Here is the way we did it.
Bring in the correct of fresh air to get an air change in 4-5 hours. Calculate the total volume of the conditioned space. This will be in the area of 100 cfm of fresh air. I suggest using a charcoal filter bed of 2"-3" of activated charcoal/potassium premagentate on a horixontal 24" X 24" X 4" merv 14 pleated filer.
The filter needs a 6" fresh air inlet and 8" house air return. Also an enough fan power to draw in and circulate the filtered air throughout the home. Most suggest that the system operate whenever the home is occupied and/or the source of the smoke is present. You need the fresh air ventilation when the home is occupied and the winds are calm because a quality built homes do not leak enough during calm winds and mild temps.
In green grass climates, I suggest including a whole house dehumidifier as part of the system for times of the year when the outdoor dew points are +55^F and there low/no cooling loads.
Units like the Ultra-Aire 100V are setup for this type of filtering. The charcoal media is available in 30 lbs. pails. The media last a season typically depending on the smoke level. 3-4 lbs. of charcoal is used load. When smoke odors come through, dump and reload. These thick beds are effective are absorbing various volatile organic gases. The merv 14 filter removes 96% of the particulate.
The fresh air is controllable on an occupancy schedule or 24/7.
If you want fresh air filterering without the dehumidifier, build up a filter box with a 6" duct fan.
It is possible that homes do not need fresh air during windy cold weather, but during mild calm wind weather, most homes need mechanical fresh air ventilation to purge indoor pollutants and renew oxygen.
