Is the air purifier useful?
What are the advantages and disadvantages of air purifiers?
1. Air purifier for activated carbon technology:
Advantages: it can absorb the odor in the air
Disadvantages: It is impossible to decompose harmful substances such as formaldehyde and benzene through physical, chemical and biological reactions to achieve the purpose of purifying air. It needs to be replaced regularly and costs are incurred continuously.
2. Air purifier for HEPA technology:
Advantages: It is the abbreviation of high eifficency oarticle air filters. Chinese means high-efficiency filter. It is effective for filtering fine particles, dust, bacteria, viruses and other substances above 0.3 microns.
Disadvantages: easy to damage, can not be washed with water, must be replaced regularly to continue to use. Maintenance is expensive. The HEPA filter has a high density and must have a powerful exhaust fan to drive air through it, which is more power hungry. Only particles and odors of pollutants flowing through the air can be filtered.
3, UV technology air purifier:
Advantages: anti-virus, sterilization function, low cost of use.
Disadvantages: UV is easy to cause damage to the cornea, skin, etc. of the human eye, and can not coexist.
4. Air purifier for ozone technology:
Advantages: Low concentrations of ozone can kill a variety of pathogens, viruses, mycoplasmas and microorganisms that are pathogenic to humans and animals that remain in the air, water, or on the surface of objects.
Disadvantages: Excessive ozone is an invisible killer, which can cause human neurotoxicity, dizziness, headache, decreased vision, and memory loss. Can not coexist with humans. Can not adsorb solid particles.
5. Air purifier with negative ion technology:
Advantages: Negative ions are combined with soot and dust particles in the air to generate soot and dust particles with static electricity, which are attracted by the ground to cause sedimentation and purify.
Disadvantages: Can not eliminate harmful gases such as formaldehyde and benzene.
6. Air purifiers for photocatalyst technology:
Advantages: It has the functions of dust removal and sterilization, and is a widely used technology.
Disadvantages: It must be activated by ultraviolet light of a specific wavelength. The life of the product is very short, the effect is not obvious, the ultraviolet light is harmful to people, and it is not suitable for human and machine coexistence during purification.

Fascia gun, also known as deep myofascial impactor, is a soft tissue rehabilitation tool that relaxes the body's soft tissue through high-frequency impact. Fascia gun can be understood as a civilian version of DMS (electric deep muscle stimulator). Its vibration frequency will change when it is used, and its basic function is similar to that of DMS. The use of the fascia gun must pay attention to the way and method. At the same time, the first use of the fascia gun should be under the guidance of professionals. It is best to use it step by step, otherwise it may cause damage.
The large round head of fascia gun is generally used for shoulder, back, hip and thigh; The small round head is used for large areas of muscles such as arms and legs. The fascia gun should be used along the muscle texture and fascia direction of the human body, not just against the muscle sores. However, a large number of nerves and blood vessels such as the head, cervical vertebra and spine cannot be used. The recommended length of use for each part is 3 to 5 minutes. The correct use of fascia gun will not lead to muscle swelling. Therefore, if this happens, it means that the muscle is damaged due to improper use. The joints, groin, armpit and other areas with rich nerves and blood vessels and no muscle protection should be avoided.
The fascia gun transmits the force and vibration to the fascia of the human body through high-frequency vibration (2000-3200 times/min), so as to increase the tissue blood flow and relax the muscles. It can also make the human tissues produce relative displacement through resonance, reduce tissue adhesion, restore the elasticity of muscles and fascia, relax the tense and stiff fascia, and relieve some discomfort symptoms of the human body.
