Product Introduction

An air purifier is a new type of household appliance that has functions such as temperature regulation, automatic smoke detection, dust filtration, odor and harmful gas elimination, dual sterilization, and negative ion release. Below is a detailed introduction to air purifiers:

Working Principle

Air purifiers typically consist of high-voltage generation circuits, negative ion generators, micro fans, air filters, and other devices. The main working principles include:

1. Electrostatic: The cathode wire in the electrostatic field generates corona discharge under high-voltage electrostatic action, producing a large number of negative ions in the corona layer. Under the influence of the electrostatic field, negative ions continuously move towards the anode, causing particles in the air to become charged and be adsorbed onto the anode plate.

2. Photocatalytic: When air passes through the photocatalytic air purification device, the photocatalyst does not change itself under light irradiation but can promote chemical reactions, degrading harmful substances in the air such as formaldehyde and benzene into non-toxic and harmless substances, while bacteria in the air are eliminated by ultraviolet light.

3. Cold catalyst: The cold catalyst, also known as a natural catalyst, is a new type of air purification material following photocatalytic deodorization materials. It can catalyze reactions at room temperature, decomposing various harmful and odorous gases into harmless and odorless substances, transforming from simple physical adsorption to chemical adsorption, simultaneously adsorbing and decomposing, removing harmful gases such as formaldehyde, benzene, xylene, toluene, and TVOC, generating water and carbon dioxide.

4. Centrifugal: Utilizing siphoning and centrifugal principles, the purification agent mixed with water is drawn into the suction pipe at the bottom of the coaxial centrifugal turbine of its motor base through siphoning. The alternating current cover motor rotates at high speed, and then using the centrifugal principle, the purification agent mixed with water is sprayed inside the bottle to form a layer of water film, drawing in dust and bacteria from the air into the water, while blowing purified air into the room.

Performance Indicators

The performance indicators of air purifiers mainly include:

1. CADR value: The Clean Air Delivery Rate, used to measure the purification capacity of air purifiers. The higher the CADR value, the better the purification effect of the air purifier. Typically, the CADR value includes the purification capacity for different pollutants such as PM2.5 particles, smoke, and pollen.

2. Particle purification efficiency: Refers to the purification effect of the air purifier on particles in the air. Generally expressed as a percentage, such as a 95% particle purification efficiency indicating that the air purifier can filter out 95% of the particles.

3. Noise: The noise level generated by the air purifier during operation is also a factor to consider. Typically, high-end air purifiers adopt noise reduction designs to ensure that they provide efficient purification without disturbing the user's daily life.

4. Energy consumption: The energy consumption of the air purifier is also a factor to consider. Choosing products with high energy efficiency can reduce operating costs while ensuring purification effectiveness.

5. Filter lifespan: The lifespan of the air purifier's filter is also a factor to consider. A longer filter lifespan indicates a lower frequency of filter replacement, which can reduce later maintenance costs.

Main Functions

The main functions of air purifiers include:

1. Formaldehyde removal: Air purifiers can effectively remove harmful gases such as formaldehyde, ensuring a safe living environment. This function is particularly important for newly renovated homes.

2. Allergen filtration: Air purifiers can filter out allergens such as pollen and pet hair from the air, effectively preventing dust, pollutants, and allergens from harming individuals with rhinitis, pollen allergies, or asthma.

3. Sterilization and disinfection: Some air purifiers also have sterilization and disinfection functions, which can kill bacteria and viruses in the air through ultraviolet light, negative ions, etc., improving indoor air quality.

4. Humidity regulation: Some high-end air purifiers also have humidification functions, which can adjust indoor humidity during dry seasons, enhancing living comfort.
