The water quality from an air conditioner outlet is generally considered to be relatively clean, often described as similar to distilled water

 The water quality from an air conditioner outlet is generally considered to be relatively clean, often described as similar to distilled water, as it primarily consists of condensed moisture from the air, making it free of many contaminants; however, while it can be used for certain purposes like plant watering, it is not typically considered safe to drink without further treatment due to potential for contaminants depending on the environment and unit maintenance. 

Key points about AC outlet water quality:

Essentially distilled:

The water produced by an air conditioner is essentially distilled water, meaning it has very few dissolved minerals. 

Slightly acidic to slightly alkaline:

The pH level of AC condensate usually falls within a neutral range, sometimes leaning slightly acidic or alkaline depending on the environment. 

Potential contaminants:

While considered clean, the water can still contain trace amounts of pollutants like dust, pollen, or mold spores present in the air. 

Suitable uses:

This water is often used for watering plants, cleaning floors, or even re-used in certain industrial applications where high purity water is needed. 

Not for drinking:

Although technically clean, it is not recommended to drink directly from an AC outlet without further purification due to potential for contamination and lack of necessary minerals.
