Main Pollutants In Air

Do you know what's in the air you're breathing? Indoor air can be 5x more polluted than outside, due to everyday factors like fine dust.


Volatile organic compounds (VOCs)

VOCs are emitted as gases from certain solids or liquids: furniture, appliances, toys, flames, scents, cooking, grooming and cleaning. Almost everything produces VOCs even humans. When contained indoors, VOC emissions may quickly rise to harmful levels. With Temtop H3, you're always conscious of VOC accumulation, and inspired to keep your air fresh.


Formaldehyde (HCHO)

HCHO is a colorless, poisonous, highly water-soluble gas with an obnoxious odor. Used in the manufacture of disinfectants, preservatives, and hundreds of industrial and consumer products such as adhesives, carpeting, decorative paneling, foam insulation, drapery, fiber and particle boards, and permanent press fabrics.
