The Shark NeverChange5 Air Purifier boasts a 5-year HEPA filter that traps 99.97% of allergens like dust, pollen, and pet dander.

The Blueair Blue Mini Max Air Purifier combines a HEPA filter with activated carbon to effectively reduce odors, making it a good choice for homes with pets or cooking smells. However, it doesn’t last as long as the Shark NeverChange5 filter, making maintenance a bit more frequent.
| Product | Filter Type | Allergen Capture | Filter Lifespan | Odor Control |
