Features and specifications in this description are as the brand describes them.
The Shark NeverChange5 is a compact air purifier with a HEPA filter built in. The brand describes it as delivering powerful purification in a sleek design, engineered to trap 99.97% of particles and reduce allergens, dust and pollutants. Shark claims the filter lasts up to five years, which the company positions as ten times longer than standard filters, and says this saves both time and money on replacements.
The purifier uses Clean Sense IQ technology, which per the brand monitors and adjusts performance intelligently. Shark also includes Debris Defense protection to ensure durability, and describes the operation as ultra-quiet so it suits any room day or night. The brand positions it as cost-effective and reliable for improving air quality.
Before purchasing, check your room size against the stated coverage area and consider where you'll place the unit in your home for optimal air circulation. The manufacturer description does not detail replacement costs or the specific performance gains in different room conditions.

Best for: Households wanting a standalone, low-maintenance air purifier with long-life filtration and zero app, network, or smart-home configuration.
The Shark NeverChange5 is a standalone portable air purifier sold in Australia in two configurations: the standard HP150 and the larger HP300 Max. SharkNinja indicates that both models use a four-stage filtration system combining a washable Debris Defense pre-filter screen, a pet particle barrier, activated carbon, and a NanoSeal HEPA filter designed to trap 99.97% of particles down to 0.1 to 0.2 microns. Shark claims the core filter can last up to five years, assisted by Clean Sense IQ sensors that track PM1, PM2.5, and PM10 particles and adjust fan output automatically across multiple speeds. Unlike connected climate appliances, the NeverChange5 contains no wireless connectivity and relies entirely on on-device physical controls.
This appliance suits homeowners and renters seeking low-maintenance air filtration without the fuss of creating accounts, installing mobile apps, or managing Wi-Fi networks. Because it operates completely offline, it suits anyone who prefers straightforward tactile buttons or wants to keep network-connected electronics out of bedrooms. The standard HP150 is sized for smaller spaces, with Shark reporting coverage of 12 square metres at 4.8 air changes per hour (or up to 60 square metres at 1 air change per hour). For larger open-plan living areas, the HP300 increases coverage to 28 square metres at 4.8 air changes per hour (up to 130 square metres at 1 air change per hour).
It will not suit smart-home users looking to automate air cleaning via Apple Home, Google Home, Amazon Alexa, SmartThings, or Home Assistant. Furthermore, according to Reviews.org, the advertised five-year filter lifespan assumes the unit runs for only 12 hours per day in compact rooms; operating the purifier continuously 24/7 or in larger, dustier environments will reduce filter life.
SharkNinja distributes the NeverChange5 locally through retailers including JB Hi-Fi, The Good Guys, Bing Lee, Appliances Online, and BIG W. Both the HP150ANZ and HP300ANZ come with a standard Australian 1.83-metre mains cord and are backed by a two-year manufacturer warranty from SharkNinja Australia. Power consumption is rated at 26W for the HP150 and 54W for the HP300. Note that official Australian listings do not publish Clean Air Delivery Rate (CADR) or decibel sound metrics, and the built-in scent cartridge requires periodic replacement if you choose to use the odour-neutralising dial.

Disappointed. It continuously shows 100% air quality run at full capacity from day one. As i live in a dusty, musty , mould-ridden wooden house built in 1910 i find this hard to believe. An enquiry to Shark got the stand ...

I bought this a few months ago and I’m extremely happy with it. I love the way it powers up after cooking and clears the air. It is quite stylish and takes up very little space.

I bought this to help clean up the air in my house during and after my kitchen renovation. It worked a treat. Thoroughly recommend this product for scrubbing out dust particles and paint smells.

I regret my purchase because the dust filter cleaning alert popped up after about two months of use, and even after cleaning it, the device wouldn't work, leaving me unable to use it
