• Ozone-free lamps allow a person to enter the area immediately after use, you can place it in different locations to work multiple times to achieve a more complete effect. If you don't want to wait after use, you can choose ozone free ones. Even with ozone-free lamps, you may feel a smell, rest assured it is not ozone.
• Ozone-containing lamps need to wait for the ozone in the air to decompose after use, Opening windows and doors for ventilation can shorten this time. If you want to cover the entire room more efficiently and deeply, you can choose ozone-containing lamps.

Warm Tips:

Keep people/pets/plants out of the area while the lamp is working, if there are large fish tanks/potted plants that can't be moved, you can cover them with an opaque cloth.
