Air pollution is a major problem facing modern society, mist, formaldehyde, etc., our life has brought trouble, and air purification is imminent, the market has also a large number of air purification products, what are the characteristics of these products, have the effect?
What are the common air purification products?
1. Air freshener
Spray air freshener is a cure, air freshener is not fresh, its own may be the source of air pollution in the car. The so-called air freshener to get rid of pollution is only borrowed from the aroma of the aromatherapy agent to cover people's feelings about the odour, the bottom can not be completely eradicated from the essence of the harmful gases, and therefore this is only a very inappropriate choice of methods.
2. Activated carbon adsorption filtration
Activated carbon is a kind of adsorbent, it has the characteristics of physical adsorption and chemical adsorption, it can selectively adsorb all types of harmful substances in the air to achieve the intention of purging and deodorising. Activated carbon should be replaced after full adsorption, about every - month replacement - times. And this method in the space scale has great limitations, beyond its effective use the scale will lose its role in air management.
3. Ozone disinfection
Borrowing ozone is a recently developed method of sterilisation. The ozone disinfection method is relatively simple to operate, will be connected to a car's special disinfectant hose in the compartment, turn on the car's special disinfectant and car air conditioning, use air conditioning air circulation, will be a car special disinfectant machine generates a high concentration of ozone sent to every nook and cranny in the car, only 5 minutes to be able to eliminate bacteria more thoroughly, disinfection after the compartment will leave a -A little ozone smell, just open the windows - instantly, the ozone will actively differentiate into colourless and odourless gas evaporated. However, this method needs to be selected - a month to disinfect - times, the effect will be very good.
4. Car oxygen bar
Car oxygen bar function is to add negative ion content in the air, negative air ions have ‘air vitamins’. Negative ions have to inhibit the growth of bacteria, and viruses, eradicate air odour, cleaning air role, the current market can be seen made into a variety of artistic appearances of cars with negative ion generators, that is, the car oxygen bar. But this method has a significant flaw, although the addition of negative ions can make the driver awake, but can not eradicate the air Huaxia have pollutants.
5. Photocatalyst
Photocatalyst is a kind of nanoscale 2 titanium oxide as a representative of the photocatalytic function of light semiconductor materials in general. Is the current international management of indoor (car) environmental pollution, the most ideal method of sterilisation?
