About the Shark HP152
The HP152 is a plastic tower in Charcoal Gray, 9.76 inches long, 9.53 inches wide and 15.16 inches tall. It weighs 9.74 pounds. It runs on 120V at 26 watts and has a 6-foot cord. Shark rates it for up to 650 square feet at one air change per hour (AHAM AC-1), a gentler standard than the one most purifiers in this guide are rated on.
Filtration has three parts. The NeverChange True HEPA filter traps 99.98% of particles at 0.1 to 0.2 microns (IEST-RP-CC007.3 basis), and Shark says it lasts up to five years. Washable Debris Defense pre-filter screens catch larger debris. An Odor Neutralizer cartridge sits in the unit and gives off a scent. Independent reviewers describe that scent as sea foam, and say it freshens the room without removing smells. It has a dial that turns the scent down, and the cartridge can be taken out.
The CleanSense IQ sensor shows air quality live on the display and drives auto mode, which adjusts the fan. Shark notes that "Clean Air 100%" means particle levels are at or below what the sensor can detect, not that the air has no pollutants. Reviewers report that the sensor reads particles only, not VOCs, and that the unit has no app or voice control. Air Purifier First says the remote is sold separately. The box holds the purifier, the pre-filter, the HEPA filter and the Odor Neutralizer cartridge.
What owners report about the Shark HP152
Owner reviews and forum threads for this exact model could not be opened, so this page cannot say what owners report.
Independent reviewers give a partial picture. TechGearLab praises the quiet running, the sensor with its auto mode, and the low upkeep, and notes a timer, sleep mode and child lock. Both it and Air Purifier First find cleaning speed behind some rivals and doubt that the whole filter set lasts five years. Air Purifier First expects the HEPA filter to need replacing sooner, and TechGearLab expects the scent cartridge to need changing every three to six months. Reviewers split on the scent: some like it, others find it too strong.
Who the Shark HP152 suits
The HP152 fits a bedroom, nursery or office up to a few hundred square feet, for someone who wants a quiet, low-maintenance machine with a live air quality readout and does not mind a light scent. Its small footprint and weight under 10 pounds make it easy to move between rooms.
Look elsewhere if you want scent-free odor control, an app, or fast cleanup of smoke and heavy pollutants in a big room. The Levoit Core 300S-P Smart Air Purifier suits a bedroom with app control, and the Coway Airmega 400S or Blueair Blue Signature Large Air Purifier suit very large rooms.
Questions about the Shark HP152
Does the Shark HP152 filter really last 5 years?
Shark says the NeverChange HEPA filter lasts up to five years. Air Purifier First doubts it and expects replacement every one to two years, and no long-term data confirms Shark's figure.
Can you replace the filter on the Shark NeverChange HP152?
Yes, but Shark's pitch is that you rarely need to. The Debris Defense pre-filter screens are washable, and the Odor Neutralizer cartridge is the part TechGearLab expects to need changing most often, every three to six months.
How big a room does the Shark HP152 cover?
Shark rates it for up to 650 square feet in one hour, at one air change per hour. That is a gentler standard than most purifiers use, so a bedroom or office is a safer fit than a large living room.
Does the Shark NeverChange HP152 odor cartridge remove smells?
No. The Air Purifier First and TechGearLab reviews describe it as adding a scent to the room instead of removing odors. You can turn the scent down with the dial or take the cartridge out.
Does the Shark HP152 have an app?
No. It has an on-unit air quality display and an auto mode, but reviewers report no app or voice control, and Air Purifier First says the remote is sold separately.

Every score here comes from our ranking model; no editor sets the order. Too few review sites cover air purifiers for their verdicts to lead, so this ranking is led by owners. It ranks products by how happy owners are, holding back any product few owners have rated until more agree. How many rated it and how new it is only settle close calls, and value for money earns its own badge rather than a higher place. We compared 20 models for this guide before settling on these ten.
Brands can't pay to be included or to move up. We last checked these picks in October 2026.
