The Shark NeverChange5 Max HP300ANZ is a sensible option if you want automatic particle sensing and a filter designed to need less frequent replacement. Its headline room-coverage figure needs context: an independent review estimates about 130 m² at 1 air change per hour (ACH), but only about 28 m² at 4.8 ACH. If you need faster air turnover, the smaller figure is the more useful guide. Shark lists HEPA filtration and Clean Sense IQ, but the evidence available does not establish an official CADR for this model, so direct performance comparisons with CADR-rated purifiers are limited.
What is the Shark NeverChange5 Max HP300ANZ?
The HP300ANZ is an air purifier sold in Australia and New Zealand. Retail listings describe HEPA filtration, a 99.97% particle-trapping claim, automatic particle sensing, and several manual fan settings. Its main selling point is the NeverChange5 filter, which is advertised to last for up to five years under stated test conditions—not as a guaranteed interval for every home.
The unit also comes with an odour-neutraliser cartridge. That is a separate feature from particle filtration: the available information does not quantify how much it reduces particular household smells or how long the cartridge lasts.

Is the HP300ANZ good for a large room?
It depends on how quickly you want the room’s air to pass through the purifier. The independent review estimates coverage of about 130 m² at 1 ACH, but about 28 m² at 4.8 ACH. For a large open room where faster particle turnover matters, treat 28 m²—not the headline 130 m²—as the more relevant estimate.
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.

- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
ACH means how many room-volumes of air a purifier can process in an hour. At 1 ACH, the room’s air is processed at a much slower rate than at 4.8 ACH. A large area figure at a low ACH therefore does not mean the purifier will clean a large room as quickly as it would a smaller one.
| Coverage estimate | Air changes per hour | How to interpret it |
|---|---|---|
| About 130 m² | 1 ACH | A low-turnover headline estimate; not the best guide if you want faster particle removal. |
| About 28 m² | 4.8 ACH | A more useful estimate when quicker air turnover is important. |
These are estimates reported by an independent review, not manufacturer-certified coverage figures. The evidence checked did not establish an official CADR for the HP300ANZ. Without CADR, there is no directly comparable published clean-air delivery figure here for matching it against CADR-rated models.
How well does its sensing and automatic mode work?
Retail listings describe Clean Sense IQ as a sensor-based feature that monitors air quality and adjusts fan power automatically. SharkNinja and retailer wording says it “tracks air quality and constantly adjusts power to maintain clean air in your home.” In practice, the appeal is convenience: the purifier can change its fan setting in response to what its sensor detects rather than relying only on a fixed manual speed.

The information available does not provide measured sensor accuracy, response times, or a controlled comparison against other purifiers. Treat Clean Sense IQ as an automatic-control feature, not evidence of independently verified performance.
What controls does the HP300ANZ have?
Listed modes include Auto, speeds 1 through 4, and Max. The independent review reports that this model does not have app control. If remote operation, schedules, or smart-home integration are essential, confirm those requirements before buying; the listed controls are on the purifier rather than through an app.
How long does the NeverChange5 filter last?
The filter is advertised to last up to five years under stated test conditions. “Up to” is important: the claim is conditional, and the available evidence does not establish that every household will get five years of use. Dust levels, usage patterns, and the conditions assumed by the manufacturer’s test can affect how closely a home matches that claim.

The box includes an odour-neutraliser cartridge as well as the filter. The evidence available does not state the cartridge’s replacement interval or cost. Before relying on a low-maintenance ownership estimate, check the current instructions for filter care, replacement eligibility, and the exact replacement part compatible with HP300ANZ.

How much does the Shark HP300ANZ cost?
Search results showed prices of roughly A$399–A$459 in Australia and NZ$449–NZ$499.99 in New Zealand. These are observed ranges rather than guaranteed current prices; retailer stock, promotions, and location can change the amount. Check the price for the exact HP300ANZ model before ordering.
What do independent sources establish about performance?
Consumer NZ lists the exact HP300ANZ in its air-purifier testing database, but detailed scores are behind a membership barrier. The public listing therefore does not support quoting a numerical Consumer NZ performance score.

Who should consider the HP300ANZ?
The HP300ANZ is most compelling for buyers who value automatic sensing and fewer filter changes, and whose room needs align with the faster-turnover coverage estimate. It is less straightforward to recommend when the deciding factor is a published CADR comparison, app control, a proven odour-removal rate, or a guaranteed filter lifespan: those details are not established by the available information.
- Consider it if: you want Auto mode, several manual speeds, and a filter advertised for up to five years under stated conditions.
- Check room size carefully if: you expect faster air turnover; use the approximately 28 m² estimate at 4.8 ACH as the practical reference.
- Look elsewhere or verify first if: you require app operation, an official CADR, detailed independent scores, or a quantified odour-cartridge replacement schedule.
Frequently Asked Questions
Can the HP300ANZ help with smoke or fine particles?
Retail listings describe HEPA filtration and a 99.97% particle-trapping claim, so the product is presented as a particle-focused purifier. The available evidence does not provide a smoke-specific CADR or independently measured smoke-removal result, so it cannot establish how quickly it will clear smoke in a particular room.
Does the HP300ANZ remove cooking or pet odours?
An odour-neutraliser cartridge is included, but the available information does not quantify its effectiveness against cooking smells, pet odours, or other gases. If odour removal is your main need, look for a model with independently documented gas or odour performance and a clearly stated replacement schedule.
Can I leave the purifier running while I sleep?
The listed noise figure is approximate and does not identify a sleep mode or specify the setting at which the figure was measured. Check whether the lowest fan setting is quiet enough for your bedroom, and confirm any display-dimming or night-mode options with the seller before purchase.
How can I confirm that a replacement filter fits the HP300ANZ?
Match the replacement part to the full model number, HP300ANZ, rather than relying on a similar product name or appearance. Confirm compatibility and availability with the manufacturer or retailer, particularly before assuming that a filter listed for another NeverChange5 model will fit.
