Air purifiers offer various benefits, such as improving indoor air quality by capturing airborne pollutants like dust, smoke, allergens, and pet dander, which can alleviate allergy and asthma symptoms[1][4][6]. They may also help reduce unpleasant odors and harmful chemicals, contributing to a healthier living environment[4][6].
However, there are drawbacks, including the initial cost and ongoing maintenance for filter replacements[1][4]. Some models can generate noise and may produce ozone, which can worsen respiratory conditions, particularly in older units[3][4]. Additionally, air purifiers might not eliminate all pollutants, particularly gaseous ones, so it's essential to set realistic expectations[3][4].
