Does UV-C light create ozone?
No, UV-C light does not produce ozone. However, the shorter Ultraviolet-V (UV-V at 185 nanometers) wavelength of UVV light actually generates ozone. This occurs because UVV light reacts with oxygen to break it into atomic oxygen, a highly unstable atom that combines with oxygen to form O3 (Ozone).
Are air purifiers with UV light safe?
How safe are UV purifiers? It’s questionable. The biggest issue with UV purifiers is that they emit varying levels of ozone. Even very small amounts of ozone in the air may result in chest pain, coughing, shortness of breath, and throat irritation.

When UV-C light is on, you will see the blue light on the front panel. UV-C light is safely contained inside the air purifier, and using it is perfectly safe.
Is an ionizer the same as ozone?
An ozone generator produces ozone that attacks the source of odor causing gases through a process called oxidation and permanently removes the odor. This is very different from a negative ion generator, or ionizer, whose primary purpose is to reduce particles like dust and pollen floating around in air spaces.
Do ion generators produce ozone?
Ozone, a lung irritant, is produced indirectly by ion generators and some other electronic air cleaners and directly by ozone generators. While indirect ozone production is of concern, there is even greater concern with the direct, and purposeful introduction of a lung irritant into indoor air.

How long can COVID-19 linger in the air?
Transmission of COVID-19 from inhalation of virus in the air can occur at distances greater than six feet. Particles from an infected person can move throughout an entire room or indoor space. The particles can also linger in the air after a person has left the room – they can remain airborne for hours in some cases.
Where is the best place to put an air purifier?
Placing your purifier near a window or close to a doorway is typically your best bet. Another reason to place purifiers near areas with a lot of airflow is that moving air has enough energy to lift dust, mold, and many other particles, which it can then distribute around your house.
Can air purifiers remove viruses?
But if a HEPA system is run over a period of time, it can take out a big chunk of viruses — somewhere in the high ninetieth percentile (99.94 to 99.97%). And long enough exposure to the UV light in an air purifying device can disable some viruses, including COVID-19.
