Page 18 Fall Home Improvement 2026 Lincoln Daily News Air purifiers… worth it, or just a bunch of hot air? What is an air purifier and how does it work? Most portable air purifiers draw room air through one or more filters, trap targeted pollutants, and circulate cleaner air back into the space. Unlike a standard heating, ventilation and air conditioning (HVAC) filter, a portable purifier is designed for continuous room-level air cleaning and can provide an additional layer of filtration when properly sized and maintained. Filtered air purifiers are generally the safest option for home use because they physically capture particles without intentionally producing ozone. Electronic air cleaners, including some ionizers and ozone-producing devices, require caution because ozone can irritate the lungs and worsen respiratory symptoms. According to the World Health Organization Trusted Source, household air pollution exposure can lead to serious health conditions such as stroke, heart disease, chronic obstructive pulmonary disease (COPD), and lung cancer. It is also important to note that the Environmental Protection Agency does not recommend any specific air cleaning device or manufacturer, so buyers should evaluate filtration type, independent certifications, clean air delivery rate (CADR), and maintenance requirements rather than relying on marketing claims alone. Are Air Purifiers Worth It? For many households, a well-matched air purifier can be a worthwhile investment
