How can I disinfect the air at home?

The simpler way to hand it over to LZ is to open the windows for frequent ventilation (even in cold winter), half an hour each morning and evening, and it is best to open the north and south windows, so that the wind direction can be unobstructed. It is also the easiest and most effective way to disinfect the air, as natural ventilation can fully exchange the dirty air accumulated in a closed room. In addition, LZ can be used every time you mop the floor, drop a few drops of 84 on the ground (if it is a wooden floor, you should first dilute the 84 liquid with a small amount of water in the basin, and then dip it with a mop), the amount does not need to be very large, there are ten drops on it, after mopping the ground, close the window and seal it for about half an hour, which can fully kill the remaining germs in the room.

It should be reminded that 84 disinfectant is very corrosive, LZ should not be directly scrubbed by hand when shabu mop, and it is best to wear gloves beforehand. I use this method to disinfect the air at home, 84 liquid is very cheap, generally available at home, and it is also very convenient, my family rarely catches a cold, and the effect is still obvious.

Now is the period of the outbreak of the new coronavirus, as everyone, we need to do a good job of relevant epidemic prevention measures, especially during the home isolation period, it is necessary to pay attention to the need to disinfect the air, which can effectively reduce the breeding and infection of bacteria and viruses, so how to disinfect the air at home? What should I pay attention to in indoor air disinfection? Let's take a brief look with Qeeka Home experts.

1. How to disinfect the air at home.

Open windows for ventilation and disinfection, and open doors and windows for half an hour of ventilation before going to bed, which can effectively reduce the indoor virus content; Fumigation and disinfection, put vinegar or peracetic acid into the pot and burn, add water and heat it with an induction cooker, and the liquid vaporizes into the air to have a disinfection effect; Ultraviolet lamp irradiation disinfection, using the sterilization function of ultraviolet light, irradiation for more than 1 hour can kill indoor air microorganisms.

2. What should be paid attention to in indoor air disinfection?

There are many ways to disinfect indoor air, including ozone disinfection, ultraviolet disinfection, alcohol disinfection, and 84 disinfection, and the effect of each disinfection method is good, but no matter which disinfection method is chosen, it is necessary to do a good job of related work, otherwise it is easy to have many problems. For example, if you use ozone for disinfection, you need to pay attention to the concentration of ozone, which is too high and is not good for the human body, and it takes at least half an hour to enter after disinfection.

The ultraviolet lamp irradiation disinfection is also noteworthy, the ultraviolet lamp will produce ultraviolet rays, ozone, etc. when working, and the disinfection effect is better, but the doors and windows need to be closed tightly to ensure the disinfection effect, and the person must not be on site during the disinfection period. If you use alcohol for disinfection, you should pay attention to high temperature and open flame.

Summary: The above is an introduction to how to disinfect the air at home, and what to pay attention to in indoor air disinfection, and regularly disinfect the air at home to make it cleaner and safer. I hope that the content shared can have some reference to the mu test, if you want to know more relevant information, you can **** Qijia information.

To disinfect the air in the home, many people may think of air purifiers, but many families are not wealthy and may not have air purifiers, so you can take some simple and effective methods at this time, the following is for reference only!

1. Spray disinfection method:

Vinegar contains acetic acid and other components, which has a certain sterilization ability and can be used for indoor air disinfection. Mix one part of vinegar with one part of water, put it into a sprayer, and spray and disinfect it after closing the doors and windows before resting at night, spraying 5 10 ml of raw vinegar per cubic meter of space in the building, disinfecting once every other day, a total of 3 sprays. If there is already a sick person in the family, the amount of vinegar should be increased to 150 250 ml per room.

2. Fumigation and disinfection method:

Close the doors and windows, pour the vinegar into a container such as an iron pot or casserole, add 2 times of water, boil over a simmer to fill the room with acetic acid vapor, until the vinegar is boiled dry, and add a little water to dissolve the residue at the bottom of the pot after the container is cooled'Vinegar sauce, then fumigation, repeat 3 times. The dosage of vinegar is 100 150 ml per house for 5 days.

3. Mugwort leaf fumigation method:

Artemisia artemisia is also known as mugwort, the volatile oil it contains, its main ingredient is eucalyptus, which has antibacterial effect on anthrax, hemolytic streptococcus, diphtheria bacillus, pneumococcus, Staphylococcus aureus, Bacillus subtilis, etc. Calculate the amount of mugwort leaves required by 1 gram of dried mugwort leaves per cubic meter, put them in an iron container and ignite them until the mugwort leaves are burned to ashes.

4. Air purifier method:

The above three disinfection methods can only maintain the effect of air disinfection for a few hours, and often return to the pre-disinfection level after 3 to 4 hours. Ultraviolet air sterilization and disinfection are now used, but this disinfection method has a certain amount of radiation and poses a potential threat to human health. The air purifier using the "plasmacluster" technology can achieve air disinfection while ensuring the safety of life.

The air disinfection ozone generator has the functions of air disinfection, sterilization, odor removal, and air purification, and has many advantages such as no dead ends, no secondary pollution, and no toxic by-products.

The ozone generator can be used for air disinfection, water disinfection, sewage treatment, object surface disinfection, cash disinfection, fruit and vegetable preservative, pipeline cleaning and disinfection, waste gas treatment, flue gas desulfurization and denitrification.

The air disinfection ozone generator is plug-and-play and supports unattended operation! The whole machine has a compact structure, a small footprint and low operating costs.

Hello, the preferred method of indoor air disinfection: natural ventilation. Opening doors and windows for natural ventilation can effectively reduce the number of microorganisms in the indoor air, improve the indoor air quality, and adjust the microclimate of the room, which is the simplest and most effective method of indoor air disinfection.

The quality of natural ventilation effect is affected by whether the ventilation of the room is good and the outdoor air quality.

With the development of the epidemic, disinfection has become a thing that everyone is trying to do, so the preferred method of indoor air disinfection is natural ventilation. In addition to natural ventilation, there are some other disinfection methods, which you can also learn about.

1. Methods of indoor air disinfection.

1. Natural ventilation. Important measures to remove indoor air pollutants and improve indoor environment and air quality. In the case of good outdoor air quality, the easiest and most effective way to disinfect and sterilize the home is to open the window for ventilation.

The longer and more often the ventilation is used, the more effective the disinfection will be.

2. Centralized air-conditioning system disinfection. The use of fans, refrigeration, heating, dehumidification, purification, etc., to adjust the indoor temperature, humidity, air cleanliness, freshness and airflow speed, is the air conditioning system and indoor air microbial concentration within the safe limit. This method is not recommended for the time being, because due to the epidemic, air conditioning can lead to cross-infection.

Ventilation and keeping the room clean.

An effective way to reduce the density of microorganisms in the room is to inject fresh air into the room at regular intervals, that is, to open windows for ventilation. It has been reported that when the indoor air is circulated to the outside world, the microorganisms in the air can be reduced in the first 30 minutes, within 75 minutes, and after 140 minutes, there are basically no bacteria, indicating that ventilation is a very simple and effective way to purify indoor air. In the hot summer, the high temperature is unbearable, the air is thin, and the convection is poor, so attention should be paid to opening doors and windows frequently for ventilation; In winter, the climate is cold and the room temperature is low, so you can keep ventilation twice a day for 20 to 30 minutes each time.

In addition, maintaining cleanliness in the room can reduce the amount and flow of indoor dust, and can also reduce the amount of microorganisms in the air.

Use an ionizer to purify the air.

Turn on the negative ion generator, and use the electric field generated by it to adsorb the inductively charged dust and suspended microbial particles in the air to achieve fresh and purified air.

Spray and fumigation.

Chlorine-containing disinfectants, peracetic acid, glutaraldehyde, chlorine dioxide, etc. can be used for air spraying and fumigation.

The concentration of chlorine-containing disinfectant (containing available chlorine) for air spray disinfection is 400 800 ppm; For fumigation, aldehyde chloride mixture (paraformaldehyde dry powder: euchlorine 24:76), the dosage is 3 grams m3, and the relative humidity is greater than 70%, ignition and closing the doors and windows for 1 hour; Or use acid chlorine fumigant to ignite fumigation, the dosage is g m3, the relative humidity is greater than 70%, and the doors and windows are closed for 1 hour.

The concentration of air spray disinfection with peracetic acid is g3 for 1 hour, and the relative humidity should be 60% 80%; During fumigation and disinfection, 3% 5% peracetic acid solution can be used for heating and fumigation, the dosage is calculated as 1 3 grams m3, the sealing effect is 1 hour, and the relative humidity is greater than 60%; If there is no heating condition, 16% 20% peracetic acid solution can be used for natural volatilization, and the dosage is 1 3 g m3 and the action time is 1 2 hours. Adding 20% 70% ethanol or isopropanol to peracetic acid can significantly enhance its disinfection effect. The residual odor of peracetic acid can be neutralized with a 5% sodium thiosulfate solution.

It is still necessary to ventilate and wash hands frequently. Whether it's after disinfecting clothes or wiping and spraying furniture with disinfectant, the most important thing is to ventilate and wash your hands. Usually when you go out, you can use cloud killing air sterilization liquid to effectively sterilize, and you can spray disinfection outside to avoid cross-infection, this is a chlorine-containing formula, which can be used by mothers and infants, and it is very safe after the elimination number certification.

1.Natural ventilation is the most economical, easy and effective way to keep indoor air fresh and reduce the concentration of bacteria. It can be used with or without people. It is of great significance to prevent the spread of SARS.

2.In the case of respiratory infectious diseases, a single air disinfection method can quickly pollute the air again because all the microorganisms in the air are killed, because the microorganisms on the contaminated surface are not killed. In this case, the more reasonable method should be to disinfect the surface of the object and disinfect the air at the same time, and spray or fumigation can be carried out with disinfectants such as peracetic acid or hydrogen peroxide.

3.The air disinfection method when people are in Minkai can choose to use a circulating air sterilizer or an air sterilizer such as electrostatic for continuous dynamic disinfection. When using this air disinfection method, it should be combined with the hygienic cleaning treatment of indoor surfaces or disinfectant to disinfect the contaminated surfaces first to ensure the air disinfection effect.

Air disinfection precautions.

1.For the corrosion of articles, peracetic acid, ozone and other disinfectants have different degrees of damage to the articles, the concentration should not be too high when using, the spray volume should not be too large, if necessary, should be scrubbed with water in time after disinfection.

2.When using disinfectants for air disinfection, it is best to use special aerosol air sterilizers, because the fog particles of the constant sprayer are large, and the disinfectant stays in the air for a short time, which is difficult to achieve the desired disinfection effect.

3.When using disinfectant for air disinfection, doors and windows should be closed, personnel should leave the disinfection place, and after the disinfection is completed, the doors and windows should be opened for ventilation, and the disinfectant should be removed before entering.

4.When exposed to ultraviolet light, it cannot be directly irradiated and exposed**, and the eyes cannot look directly at the ultraviolet lamp. so as not to cause damage to the ** and eyes.

5.Personal protection, when spraying with disinfectants such as peracetic acid, disinfection personnel should do personal protection, such as wearing masks, glasses, gloves, etc.

In order to improve indoor air quality, disinfection is generally required. What is the best way to disinfect the air at home? PChouse will take you to find out.

1. Air cleaning method. To keep the indoor air fresh, it is necessary to open the windows for ventilation for 10 to 30 minutes each time to allow the air to circulate and eliminate germs from the outside.

2. Bleaching powder disinfection method. Bleaching powder can inactivate enzymes in bacteria, causing them to die. Use 1 to 3 pieces of bleach supernatant on tables, chairs, and floors.

3. Vinegar disinfection method. Acacia vinegar contains acetic acid, which has a certain sterilization ability and is often used for indoor air disinfection. In a room of 10 square meters, you can use 100 to 150 grams of vinegar, dilute it with water 2 times, put it in a bowl and simmer it, and close the doors and windows when smoking.

4. Chemical disinfectants commonly used for air spraying and fumigation disinfection of disinfectants include: chlorine-containing disinfectants, peracetic acid, glutaraldehyde, chlorine dioxide, etc. The effect of using glutaraldehyde to disinfect the air by spray method or addition heat method is basically the same, the relative humidity is 80 90, the dosage is 250 500mg m3, and the effect is 30 minutes.
