About Hepa UV Air Purifier

What does the science say about air purifiers for Covid-19?
At the start of the pandemic, there was - as you'd expect - little to no evidence about the efficacy of air purifiers against Covid-19.
As you'd also expect, there has since been research carried out to investigate just this matter.
In November 2021, a research team at Addenbrooke's Hospital and the University of Cambridge reported that they were able to use HEPA filter/UV steriliser air purifiers to remove most airborne traces of SARS-CoV-2 on surge wards at the hospital. The air purifiers also successfully filtered out other bacterial, fungal and viral bioaerosols (airborne particles containing living organisms). However, it's worth noting they used a HEPA 14 filter (which is medical grade) in the air purifiers, rather than HEPA 13 filters, which are more commonly used in consumer appliances.
And a July 2021 report from the Centre for Disease Control (CDC) in the US also suggested that portable HEPA air cleaners could reduce exposure to SARS-CoV-2 aerosols indoors. However, it focuses on conference rooms, not household environments, and used a simulated environment.
In short, there's a lot more real-world evidence needed - and the results of these research studies don't change our advice about air purifiers and Covid.

Types of Air Purifiers
Different types of air purifiers use different technology to clean the air.
HEPA: HEPA stands for “high efficiency particulate air.” A HEPA filter is a multi-layered filter that captures particles down to 0.3 microns in size. The filter is pleated and held together with a metal frame.
Activated Carbon Technology: Air purifiers that use activated carbon technology in their filters have special properties that remove volatile organic compounds (VOCs), odors, and gas pollutants.
UV Technology: Air purifiers that use ultraviolet (UV) light use short-wave ultraviolet light (UV-C light) to deactivate pathogens like mold, bacteria, and viruses.
Negative Ion: Also known as an ionizer air purifier, these types of air purifiers use a high voltage electrical charge to attract particles to each other and clean the air. Depending on the air purifier, some use a fan, while others don’t and leave the charged particles to end up on the floor or curtains.
Ozone: Ozone can be harmful and, according to the EPA, ozone being labeled and sold as a type of air purifier isn’t truthful. Small doses of ozone that are inhaled can cause throat irritation, shortness of breath, coughing, and chest pains.
