These days, homes and commercial properties are designed with tight seals between indoor and outdoor air. While this is helpful for reducing HVAC losses, there are unintentional drawbacks. With no access to fresh outdoor air, your indoor air can become more saturated with microscopic pollutants along with common debris like dust and hair. High concentrations of airborne particles may irritate respiratory conditions and even make you sick! For truly clean, healthy indoor air, these pollutants should be extracted as much as possible.
