I've been a proponent of owning one of the best air purifiers for a long time, and I've had at least one in my home for the better part of the last three years. I've used them to clear smoke out of a kitchen with no airflow, I cranked one into overdrive during the smoke-riddled summer of 2023, and I have one next to my cat's litterbox because he loves to kick up dust.
In all of these cases, my full-size air purifiers have made a significant impact on the air quality in my home. Heck, I've even used one to cover up the smell of weed pouring through my vents from my next-door neighbor's apartment.
