How to deal with formaldehyde indoors
As people pay more attention to a healthy living environment, the issue of indoor formaldehyde pollution has become a hot topic recently. Formaldehyde is a common harmful gas, mainly derived from decoration materials, furniture, paints, etc. Long-term exposure may cause respiratory diseases and even cancer. The following is a summary of practical methods and data on formaldehyde treatment in the past 10 days across the Internet.
1. Main sources of formaldehyde
| Source Category | specific items | Formaldehyde release cycle |
|---|---|---|
| decoration materials | Artificial boards, plywood | 3-15 years |
| furniture | Sofa, wardrobe, mattress | 1-5 years |
| coating | Wall paint, wood paint | 6 months-2 years |
2. Hazard Level of Formaldehyde
| Formaldehyde concentration (mg/m³) | degree of harm | possible symptoms |
|---|---|---|
| 0.06-0.1 | light pollution | Eye irritation, throat discomfort |
| 0.1-0.3 | moderate pollution | Headache, decreased immunity |
| >0.3 | heavy pollution | Increased risk of cancer |
3. Methods to effectively remove formaldehyde
1.ventilation method: The simplest and most economical way is to open windows for ventilation for at least 3 hours a day, especially suitable for newly renovated houses.
2.Activated carbon adsorption: Activated carbon can physically adsorb formaldehyde, but it needs to be replaced regularly (it is recommended to replace it every 20 days).
3.Green plant purification: Some plants such as pothos and spider plants can absorb trace amounts of formaldehyde, but the effect is limited and other methods need to be used.
4.air purifier: Choose products with HEPA filter and activated carbon layer. The higher the CADR value, the better the effect.
5.Professional governance: Hire a formaldehyde treatment company to use photocatalyst, sealant and other technologies, which are suitable for environments where the concentration seriously exceeds the standard.
4. Comparison of recent popular formaldehyde removal products
| product type | price range | User praise rate | shortcoming |
|---|---|---|---|
| Activated carbon bag | 20-100 yuan | 85% | Need to be replaced frequently |
| air purifier | 1000-5000 yuan | 92% | Power consumption, noise |
| Formaldehyde scavenger | 50-300 yuan | 78% | Possible secondary pollution |
5. Things to note
1. It is recommended that newly renovated houses be ventilated for at least 3 months before moving in. Pregnant women and children need to extend the time to 6 months.
2. When purchasing furniture, choose E0 or ENF grade environmentally friendly standard products to reduce formaldehyde release from the source.
3. Be careful when choosing a formaldehyde detector. It is recommended to rent professional equipment or find a CMA certification agency for testing.
Through the comprehensive treatment of the above methods, indoor formaldehyde concentration can be effectively reduced. Recent measured data from netizens shows that the combined use of multiple methods can increase formaldehyde removal efficiency by more than 60%. Health is no trivial matter. Only by scientifically removing formaldehyde can you live with peace of mind!
