1. Window ventilation is a very simple method to remove formaldehyde. The principle of purification is indoor and outdoor air circulation replacement, which releases harmful gases such as free formaldehyde in indoor air to the outside and reduces indoor formaldehyde concentration. Its aldehyde removal efficiency is directly related to outdoor wind power. Generally, the greater the outdoor wind, the higher the purification efficiency.
2. Plants are the best products provided by nature outside in addition to formaldehyde, and the most popular products in the market are: green radish, chlorophytum, ivy and aloe. These plants are beautiful and talented, which can not only decorate homes, but also purify the air.
3. Activated carbon is an effective way to purify the air. It has a strong adsorption effect on harmful substances such as formaldehyde, and the smaller the particles, the better the adsorption effect. It should be noted that most activated carbons have certain adsorption limitations. Once saturated, it will no longer be absorbed, but it will desorb and release the absorbed harmful substances.
5. The fan can play the role of "inducing wind" and accelerate the exhaust of indoor gas containing free formaldehyde. This method is only useful for houses with poor ventilation, but not for houses with good ventilation effect.
6. High temperature and drying will accelerate the volatilization of harmful substances such as formaldehyde, so drawers, movable furniture, mattresses, etc. What can be taken out can be taken to the balcony for ventilation and drying, and furniture that cannot be dried can be fumigated at high temperature. Hang up, steam engine mop and high-temperature steam can accelerate formaldehyde volatilization?
