Air purifiers can be genuinely helpful, but only when they’re sized correctly, placed well, and maintained. This section focuses on practical guidance for the most common reasons people buy a purifier: allergies, pets, dust, and wildfire smoke.
We explain what air purifiers can and can’t do, how to choose a model that fits your room, and how to avoid common mistakes that lead to disappointing results.
