2. Comparison of popular formaldehyde treatment methods

The formaldehyde control methods that have been discussed most recently by netizens are as follows:

methodPrincipleEffectCost
ventilation methodDilution of formaldehyde concentration by air movementEffective in the short term, but sustainable in the long termlow

air purifierFiltration + activated carbon adsorptionBetter, but needs to be turned on for a long timehigh
photocatalytic decompositionCatalytically decomposes formaldehyde into harmless substancesBetter, but requires UV rayshigh
Plant purification (such as pothos, spider plant)Plants absorb trace amounts of formaldehydeThe effect is weaklow

3. Suggestions for scientific formaldehyde removal

1.Prevention before decoration: Choose environmentally friendly materials, such as E0-grade boards, water-based paint, etc., to reduce formaldehyde release from the source.

2.Post-renovation management:

  • Ventilate for at least 3-6 months. High temperature seasons are more conducive to formaldehyde volatilization.
  • Use it with activated carbon or air purifier and replace the filter element regularly.
  • Professional testing: Before moving in, it is recommended to find a CMA certification agency to test the formaldehyde concentration (standard: ≤0.08mg/m³).

3.Misunderstanding reminder:

  • Earthen methods such as grapefruit peels and tea leaves cannot decompose formaldehyde and can only mask the smell.
  • Formaldehyde scavengers may cause secondary pollution and need to be selected carefully.

4. Recent hot discussion cases

A netizen shared actual measurement data: After 3 months of ventilation, the formaldehyde concentration dropped from 0.25mg/m³ to 0.12mg/m³, and after adding an air purifier, it dropped to 0.05mg/m³. DescriptionCombining multiple methods is more effective.

Formaldehyde control requires patience, scientific methods and time to ensure residential safety. I hope this article can help everyone solve the formaldehyde problem in decoration more efficiently!
