PM2.5 particles are considered to be one of the harmful substances in air pollution. It not only induces respiratory diseases, but may also have adverse effects on cardiovascular health. Especially in medical places, such as hospitals and clinics, air quality is crucial to the recovery of patients. The presence of PM2.5 will increase the respiratory burden of patients and increase the risk of infection. To address this problem, Medical grade wall mounted air purifier uses its negative ion function to effectively reduce PM2.5 particles in the air, thereby providing a cleaner and safer breathing environment.

1. What are PM2.5 particles?
PM2.5 refers to particles with a diameter of less than or equal to 2.5 microns. Due to its small size and light weight, it is very easy to suspend in the air and enter the deep human body through breathing. This type of particle mainly comes from automobile exhaust, industrial emissions, construction dust and the formation of secondary aerosols. Due to its tiny size, PM2.5 particles can directly penetrate the nasal cavity and trachea and enter the alveoli, thereby posing a serious health threat to the human respiratory and cardiovascular systems.

2. How does the negative ion function of the Medical Grade Wall Mounted Air Purifier reduce PM2.5?
Negative ions are oxygen molecules or oxygen atom groups with negative charges. When the air purifier starts the negative ion function, the device releases a large number of negative oxygen ions to physically interact with pollutants in the air. These negative ions can combine with PM2.5 particles suspended in the air, causing them to aggregate into larger particles, thereby accelerating their sedimentation.

(1) Charge neutralization effect of negative ions
Most PM2.5 particles in the air carry positive charges. Negative ions release a large amount of negative charges and combine with these particles to form neutral or negatively charged particles. These particles increase in weight due to charge neutralization, thereby accelerating their sedimentation to the ground or surface.

(2) Real-time monitoring of PM2.5 and adjustment of purification strategies
The Medical grade wall mounted air purifier has a built-in PM2.5 value display function, which can monitor and display the concentration of PM2.5 particles in the air in real time. Users can adjust the wind speed mode of the air purifier in time according to the changes in the PM2.5 value. In high-speed wind mode, the release speed of negative ions is faster and the purification efficiency is higher; after the air quality improves, it can be switched to low-speed mode to maintain stable air quality.

3. The importance of reducing PM2.5 in medical environments
In hospitals or clinics, PM2.5 particles in the air not only threaten the health of patients, but also affect the working environment of medical staff. High concentrations of PM2.5 can aggravate respiratory irritation, induce lung diseases, and even affect the patient's immune system, making it less responsive to treatment.

The negative ion function of the medical grade wall mounted air purifier significantly improves air quality by reducing PM2.5 particles in the air, providing a cleaner air environment for medical places. For patients who are hospitalized for a long time, especially those with respiratory diseases, fresh air can help them recover faster.
