Nowadays, the first reaction to indoor formaldehyde is often concern. Indeed, the harm of indoor formaldehyde to the body is significant. Mild exposure can cause dizziness, coughing, and chest tightness, while severe exposure can lead to shock, coma, and even life-threatening conditions. Health is no joke, and after renovating a new home, it's essential to prepare for reducing formaldehyde pollution. Here are some practical methods:
The harm of indoor formaldehyde to the body:
1. Mild indoor air pollution
Mild indoor air pollution ranges from 0.09mg/m³ to 0.3mg/m³. It is often easily overlooked because the formaldehyde content is slightly above the standard. Initially, the body may not show significant reactions, but prolonged exposure can lead to dizziness, coughing, and chest tightness. At first, people might not associate these symptoms with indoor air pollution, thinking that more rest will help. Only when more severe symptoms like shock and coma appear does the situation become critical.
2. Severe indoor air pollution
Severe indoor air pollution ranges from 0.4mg/m³ to 0.8mg³. Compared to mild pollution, the symptoms are more pronounced, typically appearing within 24 to 48 hours. Symptoms include difficulty breathing, palpitations, sore throat, persistent low-grade fever, coughing up blood, and general fatigue. In environments with severe indoor air pollution, indoor plants may wither inexplicably, which can serve as a diagnostic criterion. Such environments are no longer suitable for living, and immediate relocation is necessary, otherwise, it may threaten life.
How to reduce formaldehyde pollution?
1. Choose eco-friendly materials
A significant amount of indoor formaldehyde comes from building materials. While purifying indoor air, it's also helpful to control the source, which can inhibit formaldehyde evaporation. Opting for more environmentally friendly materials is one of the most fundamental ways to reduce formaldehyde pollution.
2. Maintain indoor ventilation
Indoor ventilation is one of the most effective methods to remove formaldehyde. It uses air circulation to carry formaldehyde out of the room and replaces it with fresh outdoor air to reduce formaldehyde pollution. This method requires sustained effort and can be enhanced with the use of fans or other appliances to accelerate ventilation.
3. Room temperature catalytic formaldehyde removal technology
Room temperature catalytic formaldehyde removal technology is a patented invention developed by independent formaldehyde interceptors. It has received national patent certification and can convert formaldehyde into non-toxic carbon dioxide and water at room temperature without producing any by-products. It is a technology capable of eliminating indoor formaldehyde pollution.
