Migliaccio & Rathod LLP is investigating whether Shark NeverChange air purifiers, including the NeverChange Air Purifier MAX, were advertised using misleading claims about their ability to completely clean indoor air.
Certain Shark air purifiers display a “Clean Air 100%” reading, which consumers may understand to mean that all airborne pollutants have been removed. However, the reading actually indicates that detected particulate levels have fallen below the device’s sensor threshold, not that the surrounding air is completely free of pollutants. In May 2026, the National Advertising Division (NAD) determined that Shark’s advertising could mislead consumers about the meaning of the 100% reading and recommended clearer disclosures.
Migliaccio & Rathod is investigating whether consumers purchased Shark NeverChange air purifiers based on misleading representations about their air-cleaning capabilities and paid for a level of air purification that the products’ displays did not actually establish.
