You might be surprised to hear this, but indoor air quality can often be even less healthy than outdoor air quality, even if you live in a city. The reason for this is that indoor air is often affected by different pollutants than outdoor ones. Things like pollen, allergens, and smoke can deeply affect your health, especially if you or someone in your family is vulnerable to air issues.Air purifiers address these issues by addressing the root of the problem: they remove and destroy these pollutants, turning your home into a place that can be healthier than even non-polluted outdoor areas.
