What is the opinion of Reddit about the
IQAir GC MultiGas – Medical-Grade Air Purifier for Chemicals, Gases, & Odors with MultiGas & H11 HyperHEPA Pre-Filter – Odors, Smoke, Allergens, Pets, Asthma Triggers, Pollen, Dust, MCS; Swiss Made, White?

You need an IQAir multi gas air purifier, best model on the planet. Spendy but it would be the strongest tool against smoke.

This is basically the top of the line particulate/odor filter. One unit should be enough to treat your whole home. I know it’s expensive, but it has a 10 year warranty and unrivaled performance:

I would actually look up IQAIR dealers near you so you can consult with them and possibly negotiate a little bit, you might be able to get some replacement cartridges thrown in or take advantage of 0% financing.
