In winter, the doors and windows of the rooms are often closed. The indoor air is more polluted because it cannot fully exchange with the fresh outdoor air. It contains more microorganisms. In addition, it can increase the content of indoor smoke, carbon dioxide, carbon monoxide, radon gas, ozone, etc. Different degrees of harm to the baby's health, therefore, the disinfection of the room should be strengthened frequently.

Indoor disinfection in winter can start from the following four aspects:

[1]Open windows for ventilation in the room every day

For example, after waking up in the morning and before going to bed at night, open the doors and windows for half an hour to ventilate the indoor air. Investigations show that every air change can remove 60% of the original microorganisms in the air.

[2] Indoor installation of ultraviolet lamps

For example, a 30W low-ozone ultraviolet lamp is installed for every 10-15 square meters of area, and it can kill about 90% of the microorganisms in the indoor air when irradiated for more than 1 hour.

[3] Indoor disinfection with chemical fumigation

It can be fumigated with peracetic acid and vinegar. When disinfecting, inject the liquid medicine into a heat-resistant and corrosion-resistant container as needed, and place it on an electric stove, coal stove or alcohol stove to heat it to vaporize, and the liquid evaporates, and the disinfection time is calculated. When the temperature is above 15℃ and the relative humidity is above 60%, 1 gram of liquid medicine per cubic meter, fumigation for 1 hour can make the air disinfect. When disinfecting, pay attention to the corrosive items should be covered to avoid damage, and ventilate for half an hour before entering.

[4] Indoor disinfection of ignite herbal medicine

The main ingredients of this kind of disinfectant incense are Chinese herbal medicines such as pyrethrum, atractylodes, and mugwort. When using, light a plate of incense in a living room. Since the Chinese herbal medicine disinfectant incense is non-toxic and non-irritating, people can stay indoors during disinfection.

[5] Indoor use ozone disinfection machine

 Studies have shown that ozone is a broad-spectrum, high-efficiency and rapid bactericide, which can quickly kill bacteria, viruses and microorganisms. The strong oxidizing properties of ozone can destroy the structure of the above substances and make them lose their viability in a very short time. It can also remove peculiar smell. Ozone has obvious effect in eliminating peculiar smell, while ultraviolet light cannot eliminate peculiar smell. Here recommend the OGP-CF series of household air ozone disinfection machines from ozonegreenplant.
