Are PCO air purifiers safe?

Is Photocatalytic Oxidation Safe? Yes, the technology changes the air contaminants into harmless by-products and the process is effective in improving the quality of air.

Are photocatalytic air purifiers safe?

Using photocatalytic oxidation technology is a safe and effective way to improve indoor air quality. Many air purification systems produce harmful ozone; however, Cube air purifiers with PRO-Cell convert ozone into safe, healthy oxygen.

Can air purifiers be harmful?

Specific effects may include throat irritation, coughing, chest pain and shortness of breath, as well as an increased risk of respiratory infections. Some ozone air purifiers are made with an ion generator, sometimes called an ionizer, in the same unit.

Do UV-C air purifiers produce ozone?

The danger comes from oxygen particles that are broken apart by the high-energy UV-C light. These atoms then combine again with other oxygen atoms to form ozone. Therefore, UV-C air purifiers are not ozone-free. Not only do they produce ozone, they are not very effective in a residential setting.

Are UV-C air filters safe?

Other health experts state that electric air purifiers, such as electrostatic and UV light-emitting purifiers, create ozone gas. In addition to these types, ionizers and hydroxyl generators also produce ozone gas. The specialists warn that these types of filters can create potentially hazardous indoor air pollution.

What is a PCO filter?

Photocatalytic Oxidation (PCO) is a very powerful air purification technology and has the ability to destroy particles as small as 0.001 microns (nanometer) whereas HEPA filters can only filter particles as small as 0.3 microns.

What is a photocatalyst air purifier?

A photocatalytic air purifier is a specialized air filtration device using advanced technology. Air Oasis is proud to be among the first in the industry to bring you this bold new innovation, which is based on research from NASA and has been developed as a compact, efficient filter for residential and commercial use.

Are HEPA filters toxic?

HEPA filters have caused controversy over concerns that they might shed tiny fibers and be harmful to health. But the latest scientific studies have shown HEPA filters are safe and found no evidence of harm.

What is the healthiest air purifier?

Does GermGuardian produce ozone?

The manufacturer states that the UV-C bulb used in GermGuardian air purifiers does not produce ozone. Some user reviews point out that AC4825/5000 can emit a light “metallic” smell. PCO installations will make an odor as they burn off accumulated particulate after a period of operation with UV off.

Which is better air purifier or UV light?

The UV lights in air purifiers aren’t powerful enough to kill all viruses in one pass. On the other hand, HEPA filters are great at capturing viruses. Data shows they can capture over 99.9% of viruses in a single pass.

Does UV light produce ozone?

WHAT IS OZONE? … A UV lamp “tuned” to 185nm can create ozone from oxygen (O2) by disrupting the O2 molecule and splitting it into two oxygen atoms. These two oxygen atoms attempt to attach to other oxygen molecules (O2). It is the attachment of this third oxygen atom that creates ozone (O3).

Is ozone safe to breathe?

When inhaled, ozone can damage the lungs. Relatively low amounts can cause chest pain, coughing, shortness of breath and throat irritation. … Exercise during exposure to ozone causes a greater amount of ozone to be inhaled, and increases the risk of harmful respiratory effects.
