Do medical grade air purifiers work for covid?

When used properly, air and HVAC filters can help reduce airborne contaminants, including viruses, in a building or small space. By itself, cleaning or filtering air isn't enough to protect people from COVID-19. Medical HEPA filters have the highest filtration rating. This type of HEPA filter has a grade of H13-H14, which indicates that the filter can remove between 99.95% and 99.995% of particles that are only 0.1 microns in size. Thanks to their particulate retention properties, HEPA air filters are an effective line of defense to combat the spread of COVID-19 in indoor environments.

Air purifiers in the patient's room help provide efficient medical treatment and improve patient health. Air purifiers that operate at low decibels should be chosen so that the sound of air purifiers does not disturb patients' sleep in hospitals. Smart Air's practical air purifiers have been used in hospitals around the world to provide greater protection against COVID-19. The Clean Air Supply Rate (CADR) rating measures the amount of clean air that is supplied over a given period of time. Recent studies admitted that the coronavirus spreads even through breathing if the infected person survives in airborne particles for 3 hours.

Smart Air is a social enterprise certified as B-Corp that offers simple and practical air purifiers and offers free education to protect people from damage caused by air pollution. A true HEPA filter can be used in purifiers around the house to make the air cleaner and less polluted. The air purifier or air filters with a series of filters help remove fine particles, dust mites, pollen, pet dander, harmful chemicals, gases, smoke and more, and provide a clean environment and healthy. Air quality in hospitals is contaminated with chemicals used in laboratories, and the air is contaminated by sneezing, coughing and contaminants transmitted through patients' respiratory tracts.

The best air purifier for the hospital can filter and circulate enough air depending on the size of the room configuration. HEPA air filters can effectively remove nearly all particles as small as 0.1 microns from the air by capturing 99.7% of 0.3 micron particles and an even greater percentage of larger particles. When used properly, air purifiers can help reduce airborne contaminants, including viruses, in a home or in a confined space. Technically, HEPA is a category of air filter based on the size of the particulate medium and the percentage of particles that can be removed from the air when passing through the filter.

HEPA filters cannot kill the virus; they stop airborne transmission of the virus and the virus is deactivated. Adequate ventilation with a reduction in air contaminants is vital for people with poor immune systems or for people who are sick in hospitals.
