Shark NeverChange Air Purifier, HP152 Review
Bottom Line
Choose Shark NeverChange for quiet bedrooms, odors, smoke, pets, and low-maintenance filters. Skip it if you need maximum CADR, serious VOC removal, reliable dust automation, or app control.
Best for
Best for bedrooms, apartments, pet homes, light smoke or cooking odors, and users who want a quiet purifier with clear air-quality feedback and simple maintenance.
Not for
Not ideal for buyers who need high CADR value, serious VOC removal, app or voice controls, fragrance-free odor control, or automatic dust pickup they can fully trust.
Verdict
The Shark NeverChange earns broad praise for quiet operation, easy controls, visible air-quality feedback, and fast real-world reactions to smoke, cooking odors, pet smells, and allergy triggers. Expert testing supports strong particle reduction and very low running costs, helped by washable pre-filters and the long-life filter concept. The tradeoff is power and trust: some lab evidence calls the smaller model underpowered for the price, several reviewers doubt the five-year filter claim, and customer reports show occasional sensor or auto/eco-mode problems. It is best viewed as a low-maintenance, user-friendly purifier for bedrooms and everyday odor or allergen control, not as the strongest CADR-per-dollar option.

FAQ
Does Shark NeverChange remove smoke well?
Yes. Expert and customer reviews repeatedly describe quick responses to cooking smoke, cigarette smoke, wildfire smoke, and smoky test conditions.
Is the five-year filter claim reliable?
Reviewers are divided. The long-life filter is a major appeal, but several expert and customer reviews expect replacement sooner in dusty, smoky, or pet-heavy homes.
Is it quiet enough for a bedroom?
Usually yes. Low speeds are repeatedly described as quiet or sleep-friendly, though high or max settings can be noticeable when air quality drops.
Does it help with pet odors and dander?
Most pet-owner reviews are positive for dander and odor, but one detailed review says auto/eco mode is poor at detecting pet hair.
Does it have app or Wi-Fi control?
No. Expert reviews note the lack of app and Wi-Fi connectivity, which is a drawback at this price.
Is the scent cartridge required?
No. Several reviewers use it or like it, while others turn it off or remove it because the smell is strong, artificial, or irritating.
