To naturally purify air at home, place air-purifying plants like Peace Lily, Spider Plant, and Bamboo Palm, which absorb toxins and release oxygen. Improve ventilation by opening windows and using exhaust fans to reduce indoor pollutants. Activated charcoal or Himalayan salt lamps can also help absorb impurities. Moreover, adding natural essential oils such as tea tree or eucalyptus may help to diminish airborne bacteria while keeping the air fresh naturally.
