Newly renovated houses are often accompanied by pungent decoration smells, which mainly come from harmful substances such as formaldehyde, benzene, and TVOC. How to effectively remove these odors has become a concern for many owners. The following are practical methods for deodorizing new homes that have been hot topics on the Internet in the past 10 days. They are combined with scientific data and netizen experience to provide you with comprehensive solutions.
1. Sources and hazards of odor in new houses
The odor in newly renovated houses mainly comes from the following materials:
| Source | Main hazardous substances | Hazard |
|---|---|---|
| Board materials (such as plywood, density board) | Formaldehyde | Carcinogenic, irritating respiratory tract |
| Paints and coatings | Benzene, TVOC | Dizziness, nausea, affecting the central nervous system |
| Glue, adhesive | Formaldehyde, ammonia | Eye irritation, skin irritation |
| Carpets, curtains | TVOC | Headache, fatigue |
2. Scientific and effective deodorization methods
Based on the hotly discussed deodorization methods across the Internet, we have compiled the following efficient solutions:
| method | Operation mode | Effect | Things to note |
|---|---|---|---|
| ventilation method | Open windows 6-8 hours a day for cross ventilation | ★★★★★ | Avoid opening windows on rainy days |
| Activated carbon adsorption | Place 500g activated carbon packs every 10㎡ | ★★★☆☆ | Monthly replacement or exposure to sunlight |
| Green plant purification | Place 1-2 pots of pothos/monstera per 10㎡ | ★★☆☆☆ | Auxiliary effect, need to be combined with other methods |
| air purifier | Choose a model with CADR value >300m³/h | ★★★★☆ | Replace filter element regularly |
| Photocatalyst treatment | Professional construction spray photocatalyst solution | ★★★★☆ | Requires UV irradiation to be effective |
3. Effective folk remedies tested by netizens
On major social platforms, many netizens have shared their own personally tested and effective deodorizing methods:
1.Tea water fumigation method: Use boiled tea water (black tea works best) and place it in every corner of the room. The water vapor can absorb part of the formaldehyde.
2.White vinegar + water: Mix it in a ratio of 1:1 and put it in a basin. Change it every two days. It has a neutralizing effect on ammonia.
3.Grapefruit peel/pineapple peel: Although it cannot decompose formaldehyde, it can effectively mask odor and is suitable for short-term use.
4.Industrial fans speed up ventilation: Used in conjunction with opening windows, it can increase ventilation efficiency by 5-8 times.
4. Comparison of professional formaldehyde removal services
For households that are in a hurry to move in or have serious pollution, professional aldehyde removal services may be considered. The following is a comparison of popular aldehyde removal methods:
| Service type | Unit price (yuan/㎡) | Validity period | Advantages | Disadvantages |
|---|---|---|---|---|
| High temperature fumigation | 15-25 | 1-2 months | Quick effect | May damage furniture |
| Sealing agent | 20-35 | 3-5 years | Effective for a long time | Does not break down pollutants |
| biological enzymes | 30-50 | 6-12 months | Environmentally friendly and non-toxic | Requires multiple constructions |
| Nano photocatalyst | 40-60 | 2-3 years | Continuous decomposition | Requires light conditions |
5. Pre-move-in testing recommendations
Be sure to conduct air quality testing before moving in. The following two methods are recommended:
1.Professional organization testing: Choose a CMA certification agency. The testing items should include formaldehyde, benzene, and TVOC. The cost is about 300-500 yuan/point.
2.Self-test box/detector: Can be used for daily monitoring, but the accuracy is low. Price reference for popular brands:
| product type | price range | Accuracy |
|---|---|---|
| Formaldehyde self-test box | 5-15 yuan/box | ±0.1mg/m³ |
| Electronic detector | 200-800 yuan | ±0.01mg/m³ |
| Intelligent detector | 1000-3000 yuan | ±0.005mg/m³ |
6. Comprehensive deodorization schedule
According to the pollutant volatilization cycle, it is recommended to process according to the following time points:
| time period | Treatment method | target concentration |
|---|---|---|
| 0-7 days after decoration | All-day ventilation + industrial fan | Formaldehyde＜1.0mg/m³ |
| 8-30 days | Ventilation + activated carbon + green plants | Formaldehyde＜0.2mg/m³ |
| 1-3 months | Regular testing + air purifier | Formaldehyde＜0.1mg/m³ |
| 3 months later | Routine maintenance inspection | Formaldehyde＜0.08mg/m³ |
Through the above systematic deodorization solutions, most new houses can reach safe occupancy standards within 1-3 months. Special reminder to pregnant women, children, the elderly and other sensitive groups, it is recommended to ventilate the hotel for at least 6 months before moving in.
