1, physical barrier filtering:
That is, the circulating level of flue gas is improved by environmental protection cotton, so that tar and solid substances in flue gas are attached to the filter cotton, and the filtering effect is enhanced.
When smoking, nicotine enters the lungs through the throat, which is harmful to human health. Although wearing a filter can reduce some nicotine from entering the mouth and lungs, most of it will still enter the human body. Because smokers are also direct participants in smoke, wearing a cigarette holder will only reduce the harm.
2. Air specific flow filtration:
By controlling the airflow speed to reduce the tar content, the tar will adhere to the filter element, and the smoke in the flue gas will also fall into the cavity when slowing down, forming a mixture with the smoke tar, so that a large number of harmful substances will be trapped in the cavity.
3, magnet filtration:
The magnetic field of the magnet will make the smoke flow in the direction of the magnetic field when passing by, and the magnet itself is cold, which is the effect of tar and smoke interception.
Filtering cigarette holders can only reduce the intake of harmful substances and cannot completely prevent harmful substances from invading the body, so it is best to quit smoking.
Disadvantages:
1, it is necessary to clean the cigarette holder in time and maintain it reasonably, otherwise it is not conducive to healthy use.
2, more wasteful, more used.
Extended data:
Filter cigarette holder, also known as health cigarette holder, can filter out most harmful substances in cigarettes and protect human health. But also can improve the quality of cigarettes and reduce the tar content of cigarettes.
Material characteristics: particle size distribution (gradient structure).
Phase: inorganic material.
Safety: no toxic side effects, safe and reliable.
Material function: improve cigarette quality, soft and easy to suck, reduce tar content of cigarette; Purify harmful impurities in smoke and dust, and reduce the irritation of smoke and dust to respiratory tract.
Generally divided into disposable, core-changing and cleaning. Disposable type, directly discarded after sucking a certain amount; The filter system in the middle of the cigarette holder is placed separately, which can be taken out directly after a certain amount of suction and replaced with a new filter element for direct use; Cleaning type, that is, the filter part of the cigarette holder can generally be pulled out freely, and can be used again after wiping or cleaning, and can be cleaned for many times.
