Shark NeverChange Air Purifier HP152: Specs, Pros & Cons
Shark's HP152 runs on 26 W, well under what most purifiers draw, and it is built so the expensive filter stays put while everything in front of it gets rinsed. That pairing of low power and very few consumables sets it apart from most small-room purifiers, where the running cost tends to come from one or the other.
The filtration has four stages. Debris Defense screens catch hair and dust first and can go under a tap, a carbon layer deals with smells, and a True HEPA cartridge waits at the back. That cartridge is the NeverChange of the name, and a replacement indicator is there for the day it finally needs one.
Control is kept to the basics. A sensor watches the air and runs the auto mode, and a timer sets how long it stays on. There is no sleep mode, which is an odd gap on a purifier aimed at bedrooms and nurseries, and no app or voice assistant, so everything happens on the purifier itself. At 4.42 kg it is easy to carry from room to room.
The difficult part for a comparison site is placing it. Shark publishes no clean air delivery rate and is absent from the AHAM directory, so its airflow cannot be set against a Levoit or a Coway, and its room claim describes a single air change an hour. That sizes it, in practice, for small rooms. The obvious buyer is a pet household with a bedroom, study or dorm to clean, where hair would otherwise clog a disposable filter, and it leaves anyone who needs to size a larger space by the numbers without a figure to work from.

How this VS Score was computed
Score 71: each known spec is measured against the median of all air purifiers (41 products), then weighted; 50 means level with that median. In classes of six or more, a value beyond the class’s 10th–90th percentile range counts as that limit, so one extreme product cannot set the scale. 36% of the scoreable weight could be used; unknown values, features not applicable to this class and proxies (battery capacity where a rated life exists) add or remove nothing.

Editor’s note
The NeverChange is one idea taken literally: a filter Shark says lasts up to five years. On a category where two filter changes a year can cost as much as the machine, that is a real economic argument, and Shark makes it directly: it claims a saving on replacement filters over five years against typical budget competitors.
The design follows from that. Rinseable Debris Defense screens catch hair and large debris before they reach the cartridge, which is what makes the long filter life plausible, and there is a carbon layer for odors. For a pet household that is the right architecture, because the hair ends up on something washable.
Now the part that should temper enthusiasm, and it is significant for a comparison site: Shark publishes no CADR figure at all (not smoke, not dust, not pollen), and it does not appear in the AHAM Verifide directory. So the only number on offer is "up to 650 square feet", and that is quoted at a single air change per hour, which is nowhere near enough turnover to do much. At the four to five air changes an hour that allergy and asthma guidance calls for, the real figure is a fraction of that.
That makes it very hard to place against a Levoit, Coway or Winix, all of which publish certified numbers.
So: for a bedroom, nursery, home office or dorm, where the marketing figure and reality diverge least, and especially for a pet household tired of buying filters, it makes sense at its list price. For a large open-plan room, or for anyone who needs to prove coverage, buy something with a certified CADR instead.

The bottom line
The Shark NeverChange Air Purifier HP152 earns a VS Score of 71 on the 36% of specifications we could compare like for like — an indication, not a ranking.
- Who it’s for
- Bedrooms, nurseries, home offices and dorms (small rooms), and pet households sick of buying replacement filters, where a five-year cartridge and rinseable pre-screens are worth real money.
- Who should look elsewhere
- Anyone shopping on CADR or who needs to prove coverage for a room size: Shark publishes no CADR and is not AHAM Verifide. Also wrong for large or open-plan spaces, since the coverage claim is a one-air-change-per-hour figure.
- The trade-off that matters
- Near-zero running cost in exchange for unverifiable performance. The five-year filter is a genuine saving, but the absence of any certified airflow number means you cannot compare it with anything else.
- The main alternative
- Levoit Core 400S: a fraction of the running-cost advantage but an AHAM-certified CADR and a published coverage figure you can size a room with.
