Shark NeverChange5 Air Purifier for Home, Bedroom, Room Coverage 60sqm, 5-Year HEPA Filter Traps 99.97% of Allergens including Dust, Pollen, Pet Dander, Auto Mode, Quiet, LED Display, White HP150UK

The Shark NeverChange5 has one thing going for it that nothing else at this price offers: the HEPA filter is rated to last five years before needing replacement. Every other purifier in this range needs a new filter every 6-12 months at £20-£40 a time. Over five years, that adds up.

The five-year filter claim

Shark tested this to the GB/T18801-2015 standard, based on 12 hours daily use at max speed in a 12 m² room. In a larger room or with heavier pollution, the filter will degrade faster. But even at three or four years, you're still well ahead of the competition on running costs. Our air purifier electricity cost guide breaks down the ongoing costs for different models, and the Shark comes out well.

Coverage

60 m² with one air change per hour, or 12 m² with nearly five changes per hour. That makes it a bedroom or small living room unit. It's not going to handle a big open-plan space. For larger rooms, the Levoit Core 400S or Philips 3000i are better suited. Our best air purifier for large rooms guide has the numbers.

For bedrooms specifically, our best air purifier for bedroom guide compares this to other compact models.

Air quality monitoring

Clean Sense IQ reads the air and adjusts fan speed automatically. The LED display shows real-time air quality so you can see it reacting. Open a window or start cooking and the fan ramps up. Standard for mid-range purifiers now, but Shark's implementation works well enough.

Noise

Shark call it quiet and it is on lower settings. On max it's audible. The display dims for nighttime use. Not as silent as the Levoit range on sleep mode, but fine for a bedroom. We tested several for overnight use in our quiet air purifier for sleeping roundup.

Who it's for

People who don't want to think about replacement filters. If the ongoing cost and hassle of swapping filters every few months puts you off air purifiers, this removes that problem. The purification is fine for the room size. 4-layer HEPA system, handles pollen, dust, pet dander.
