Household particulates are tiny solid or liquid particles found in the air within homes. These can include dust, pollen, pet dander, and smoke from cooking or heating. They can vary in size and composition, affecting indoor air quality and potentially leading to health issues, especially for individuals with respiratory conditions. Common sources of household particulates include vacuuming, cooking, and burning candles. Proper ventilation and regular cleaning can help reduce the concentration of these particles. Using air purifiers can also improve indoor air quality by filtering out harmful particulates, making the home environment healthier for its occupants.
