===Coronal discharge method===

This is the most common type of ozone generator for most industrial and personal uses. While variations of the "hot spark" coronal discharge method of ozone production exist, including medical grade and industrial grade ozone generators, these units usually work by means of a [[corona discharge|corona discharge tube]] or ozone plate.<ref>{{cite web |title=Ozone Cell vs Ozone Plate – A2Z Ozone |work=A2Z Ozone |url=https://www.a2zozone.com/blogs/news/ozone-tube-vs-ozone-plate |access-date=2020-01-10 |archive-url=https://web.archive.org/web/20200110211607/https://www.a2zozone.com/blogs/news/ozone-tube-vs-ozone-plate |archive-date=2020-01-10}}</ref><ref>{{OrgSynth|last1=Smith|first1=L.

Fluctuations in ambient air, due to weather or other environmental conditions, cause variability in ozone production. However, they also produce [[nitrogen oxide]]s as a by-product. Use of an [[air dryer]] can reduce or eliminate nitric acid formation by removing water vapor and increase ozone production. At room temperature, nitric acid will form into a vapour that is hazardous if inhaled. Symptoms can include chest pain, shortness of breath, headaches and a dry nose and throat causing a burning sensation. Use of an [[oxygen concentrator]] can further increase the ozone production and further reduce the risk of nitric acid formation by removing not only the water vapor, but also the bulk of the nitrogen.
