A chief selling point of vinyl flooring is that it's easy to clean, an obvious health benefit. In addition, some manufacturers top their products with antimicrobial coatings or embed wear layers with particles of silver, a potent germ killer.
The knock against vinyl has more to do with indoor air quality. This is due to the potentially lung-irritating and headache-inducing VOCs that are off-gassed by vinyl flooring and the glues traditionally used to hold it down. If you want to breathe easy, choose FloorScore-certified coverings and adhesives, which meet the building industry's most stringent indoor-air-quality standards.
