Care Guide
What kind of maintenance is required?

The only maintenance needed is to replace the Reaction Chambers. The unit will prompt you with an indicator light when it is time to change (about once a year). The Reaction Chamber

Does the grill require any special care/cleaning?

You should dust your unit just as you would any other item in your home. If you happen to spill something on the outside of your Airocide, use a damp, clean cloth to wipe it down.

Compared to Other Technologies

Other Technologies:

HEPA: HEPA filters are in fact useful , but if you need an air purifier, you do not need to purchase one. Why? Modern homes are equipped with air conditioning and heating systems. HEPA filters are the ones that need to be changed every month or three months. It is likely that every square inch in your house is going through a HEPA every hour. You need more than just a HEPA air filter if you are still experiencing negative effects.

Ozone: Airocide does not produce Ozone. The lab results are proof, as well as clearances from FDA and California Air Resources Board. There is a good reason why we spent so much time making sure our products were Ozone-free. Ozone can be dangerous. Inhaled ozone can cause serious health issues. It destroys lung tissue. In some places like California, Ozone generators are outright prohibited in populated areas. There is still some confusion about what an Ozone generator is. Some products are labeled Ion Generators or Electrostatic Precipitators. Don't be misled. All of these produce dangerous levels of Ozone.

PECO: A recent air purification technology on the market is often positioned to be a "successor" technology to PCO (The Airocide Technology). Do not be misled. PECO is not a scientific term but a marketing one. PCO was discovered several decades ago by Japanese Scientists. NASA refined it to suit their needs, which is how Airocide was born. Airocide is the result of over 30 years of research and testing. The science has been proven.
