Clean air shouldn't come at the cost of your peace and quiet. While air purifiers are essential for removing allergens, smoke, and pet dander, their internal high-RPM fans generate mechanical vibration that travels down into hard flooring, side tables, or nightstands. Decoupling your air purifier with Sorbothane® viscoelastic polymer stops structure-borne resonance, delivering up to a 6 dB drop in sound levels.
