Introduction
Air purifiers have been on the market for years, but sales of these devices have increased dramatically over the course of the most recent season in the wake of a particularly nasty flu outbreak.  Many people have purchased these products to combat the spread of airborne viruses like the Covid-19, which can be spread by exposure to small droplets and particles of the virus that linger in the air for minutes, or even hours after transmission.

A number of technologies are used in air purifiers, including mechanical filtration, electrostatic precipitation, gas phase absorption, and chemical reaction. Many air purifiers have multiple filters for pulling different kinds of pollutants from the air. Some of the most common pollutants that can be removed by air purifiers include dust, pollen, mold spores, pet dander, cigarette smoke, cooking odors, and volatile organic compounds.

There are a variety of air purifiers out there, but their effectiveness may vary depending on the type of air purifier you use. The most popular types of air purifiers include HEPA (High-Efficiency Particulate Air) models, UV (ultraviolet) air cleaners, activated carbon air filters, and ionic purifiers.

Short-wave ultraviolet light inactivates airborne pathogens that can cause ailments. Air purifiers employ UV-C lights to eliminate mold, bacteria, and viruses. These devices are a must for people who suffer from allergies or other ailments as the result of exposure to airborne pollutants.

How Can Air Purifiers Be Used to Eradicate the Coronavirus?
While it is easy to neglect our personal health when the threat of an airborne epidemic creeps up on us, there are ways to lower our risk. Using a portable air purifier with HEPA filtration that can remove 99 per cent of contaminants from the air, including the respiratory droplets that spread the coronavirus, is one way to lower your risk.

The filter media within these air purifiers traps the virus. Once viruses are trapped, they cannot grow and cannot be released. Ionizer purifiers are another type of air purifier known to be effective against Covid-19. Special electrodes in ionizers generate an electrical charge, which sticks to the viruses, thereby killing them.

Once a virus has been destroyed and no longer poses further harm, its genetic material is stuck to charged surfaces like walls and tables which are easily wiped down with a cloth. Data has shown that UV light kills the coronavirus, so UV air purifiers seem to be the best way to protect you against it.

Both an ionizer air purifier and a UV light air purifier are effective against Covid-19. An ionizer air purifier releases harmful and dangerous pollutants, such as ozone, but a HEPA filter air purifier does not. A UV light air purifier releases ultraviolet light.

Performance Optimization of Air Purifiers
An air purifier is a lifesaver when you need to eliminate harmful pollutants from the air. It can be tricky to determine the proper settings to use, and a few things must be kept in mind for the best air quality.

The first step is to ensure there are no foreign objects blocking the air intake and outlet passages. In order to trap and remove more allergens and microorganisms, the device must be able to draw in large amounts of air. By ensuring that this process is trouble-free, the purifier can better distribute clean, fresh air throughout your home or office.

Secondly, to get the full effect of an air purifier, it is important to keep all windows and doors shut. The air purifier will remove harmful particles more effectively if the room is kept sealed.

Third, it is recommended to leave an air purifier running at home in an automatic mode. The auto-mode feature will continually monitor the quality of the air by detecting the levels of pollutants in the air and automatically adjust fan speed to improve air quality.

If the pollutant level increases in a room, it will automatically increase the fan speed of the air purifier to its maximum. If it detects that there is not enough pollution in the air, it will set the fan to its lowest speed. The machine operates quietly and needs less energy while on low speed.

An air purifier can also degrade air quality, and regular maintenance is required to avoid this. Filters should be washed and dried after every ten to fifteen days of use.

How to Choose the Right Air Purifier
Choosing the right air purifier can be difficult for consumers. For the average space, experts suggest choosing an air purifier that cleans 30 to 50 square feet per minute of space. Consumers with allergies or asthma may want to choose a higher air change per hour rate.

There are a variety of extra features available for air purifiers, and buyers should consider each of these qualities before making a final purchase. Features like energy efficiency can help you save money while also conserving energy, auto mode adjusts the air flow speed based on the levels of detected pollutants, and advanced features like Wi-Fi connectivity can even help you stay connected with your air purifier.

When it comes to fighting Covid-19, air purifiers are not a panacea. Wearing masks and practicing good social distancing are critical to reducing the spread of the virus.

Conclusion
A complete risk mitigation strategy for the transmission of COVID-19, an airborne virus, includes public health measures and air purifiers. Physical distancing, masking, cough and sneeze etiquette, cleaning and disinfection may be supported by ventilation or filtration and by the use of special air purifiers such as portable ones.

There is no scientific evidence that directly demonstrates the effectiveness of portable air cleaners in reducing cold-like viruses. However, because the virus particles are so small, it is likely that a HEPA filter would be effective at removing them from indoor air. As such, portable air cleaners should not be relied upon as the only mitigating measure where source control is not available.
