Opening windows effectively removes formaldehyde
Opening all windows in a newly renovated home creates airflow between indoors and outdoors, reducing harmful substances in indoor air. However, this alone cannot completely eliminate all formaldehyde.
Black tea effectively removes formaldehyde
Steep 300 grams of black tea in two basins of hot water. Place the solution in the newly renovated space with doors and windows open for ventilation. Within 48 hours, indoor formaldehyde levels will decrease by over 90%, and the pungent odor will largely dissipate.
Activated carbon effectively removes formaldehyde
Purchase 800 grams of granular activated carbon to eliminate formaldehyde in new homes. Divide the carbon into 8 portions and place them in dishes. Position two to three dishes per room; within 72 hours, most indoor odors will be eliminated.
Coal ash effectively removes formaldehyde
Distribute 400 grams of prepared coal ash into basins and place them throughout rooms requiring formaldehyde removal. Within one week, formaldehyde levels will drop to safe ranges.
Cold water with vinegar effectively removes formaldehyde
Fill a basin with cold water, add an appropriate amount of vinegar, and place it in a well-ventilated room. This will eliminate residual toxic gases.
Plants can effectively remove formaldehyde
Place plants with formaldehyde-absorbing properties in newly renovated homes. Within two weeks, all formaldehyde in the home will be eliminated. Plants with formaldehyde-absorbing properties include spider plants, aloe vera, agave, snake plants, and pothos.
