water air freshener

1. The Basic Principle of Air Freshener 1.1 Working Principle of spray Air Freshener Spray air freshener are produced by spraying liquid formulas into the air in the form of tiny particles through pressure vessels or mechanical pumps. These particles can: • Neutralize the odor molecules in the air. • Some products contain antibacterial ingredients. • Release aromatic molecules to improve air perception. According to research by the US Environmental Protection Agency (EPA), most air fresheners work in one of two ways: either by masking odors or by chemically interrupting odor molecules (EPA,2022). 1.2 Main Component Analysis Typical spray-based air fresheners may contain: propellants (such as compressed gas), solvents (such […]
