Working Mechanism of Zero2.5 Negative Ion Air Purifier 

The polluting air contains a significant amount of harmful PM2.5 pollutants, which are fine and ultra-fine particles at least thirty times smaller than the diameter of human hair and invisible to the human eye. The Zero2.5 Negative Ion Air Purifier generates negative air ions that attach to these fine particles, such as black soot, causing them to clump together, become heavier, and settle out of the air. These clumped particles become visible black dusts, making them easier to remove and improving air quality.

However, using the Zero2.5 Negative Ion Air Purifier near walls could lead to a buildup of these clumped black soot or dust particles on the walls, appearing as black marks over time. The intensity of this buildup depends on the air quality in the space. Regular cleaning of the walls is required to prevent the black marks from darkening due to prolonged accumulation.

Cleaning Instructions:

 Use our Dry-Cleaning Soot Sponge to clean visible black marks on certain surfaces like gypsum boards, painted plaster walls, and wall coverings. Keep the chemical soot sponge dry to clean surfaces without wetting them. It effectively wipes away particulate matter, dust, soot, pet hair, mold, and other stubborn dirt stains. Made of vulcanized natural rubber, the sponge is non-greasy, leaves no residue, and is safe for use on delicate fabrics.

Excluded surfaces:

Laminates, Metal or Plastic surfaces. For these excluded surfaces, we recommend using mild alcohol solvent to apply to the affected spot, and cleaning with a soft dry cloth.


Unused sponges should be stored in a normal temp room, in a box or wrapped in dark plastic, away from direct sunlight or heat sources.

It is normal for the sponge to turn pinkish or reddish and does not change the effectiveness of the sponge. It tends to happen in warmer seasons.
