Answer

No, that is not correct.

In Jainism, simply having a ventilator, a small indoor fountain, or an aquarium does not mean that there are no air-bodied beings or water-bodied beings in your house.

Explanation

• Air-bodied beings (vayukaya) are understood in Jainism as living beings connected with air itself. A fan, ventilator, or indoor airflow does not remove their existence.
• Water-bodied beings (apkaya) are understood as living beings associated with water. A fountain or aquarium can actually become a place where water-bodied life is present.
• An aquarium especially contains living beings and is not considered “life-free.” It is a direct habitat for many jivas.

So, from the Jain point of view, these things do not make the house free from those kinds of beings.

Spiritual Understanding

Jain Dharma teaches deep ahimsa and respect for all forms of life, even very subtle ones. The purpose is not to assume that life is absent just because we cannot see it.

• Visible life is easy to recognize.
• Subtle life may not be visible, but it is still respected in Jain thinking.

That is why Jain discipline encourages careful living, clean and responsible use of water, and avoiding unnecessary harm to living beings.

Takeaway

A ventilator does not make air “non-living,” and a fountain or aquarium does not make water “life-free.” In Jainism, it is safer to assume that living beings may be present and to act with care and non-violence.
