Ozone  is a strong oxidant, a light blue gas with a fishy smell, it is heavier than air, and at a certain temperature, it will decompose itself into oxygen over time. when the human body inhales ozone, it will irritate and damage the mucous membrane of the respiratory tract. The degree of damage depends on the concentration of ozone inhaled and the length of inhalation.Ozone always exists in the environment we live in, the general concentration is around 0.015PPM, and we can't feel its existence. When the concentration reaches 0.02PPM, sensitive people will smell ozone.


The US UL867 safety standard for ozone is ≤0.05PPM, and the EU standard is formulated with reference to the US standard. my country's standard GB simply says that UL867 means that under laboratory conditions (temperature 25°C, humidity 50%), the cumulative concentration produced by any ozone source cannot exceed 0.05PPM.The direct damage of ozone to the human body will cause significant damage to the human respiratory system, cause eye irritation, cause respiratory diseases, and even asthma.

At the same time, it has a certain hidden harm to the human body. If you are in an environment where ozone exceeds the standard for a long time, your heartbeat will speed up and you will be restless. The medical community has reached a consensus that ozone can induce some latent or invisible diseases in the human body.


OSHA (Occupational Safety and Health Administration)

  *OSHA Permissible Exposure Limit (PEL) guidelines for O3 in the workplace are based on time-weighted averages (TWA). 0.1 ppm for 8 hour work shift for a 40 hour work week.*

 -OSHA requires that if you are generating ozone that you measure this ozone level for safety purposes

 -The OSHA website cites the following exposure limits for ozone in the workplace:

   *0.1 ppm PEL for 8 hours per day (TWA) exposure for General Industry

   *0.1 ppm PEL for 8 hours per day (TWA) exposure for Construction Industry

   *0.1 ppm PEL for 8 hours per day (TWA) exposure for Shipyard Employment

   *0.3 ppm Short Term Exposure Limit (STEL) for a 15 minute time weighted average (TWA) exposure which is not to be exceeded at any time during a workday even if the time-weighted average is below the PEL.

The oil fume filter uses mechanical or electrostatic adsorption to group and separate the oil fume exhaust gas, and electrically separates the oil fume particles to achieve the purpose of purifying the oil fume. It has a wide range of applications in the industrial field, mainly reflected in the following aspects:

1. Factory and kitchen oil fume purifier: In factories and large kitchens, the generation of oil fume is the most important. Industrial oil fume filters, as stronger oil fume purification equipment, can effectively remove these oil fumes and protect the environment and workers' health. This is very important for improving the working environment, maintaining employee health, and enhancing corporate image and competitiveness.

Ozone filter is a filter specially used to remove ozone. Its main application principle is to convert ozone into oxygen through a catalyst to purify the air. Ozone removal filters have the following industrial applications: ● Industrial waste gas treatment. A large amount of exhaust gas will be produced during industrial production, which may contain harmful gases such as ozone, so as to protect the environment and human health;

Baffle grease filter and mesh grease filter are two common grease filters. They are different in structure and working principle. The following are their differences, advantages and disadvantages:Baffle grease filter
Structure: The baffle grease filter consists of a series of metal baffles forming a closed channel. When oil fume passes through the channel, the oil droplets will be separated and collected due to wind resistance and baffles.
