Shark NeverChange5 Air Purifier in White

The 'NeverChange5' name refers to Shark's claim that the five filtration stages are designed to be cleaned rather than replaced, using a washable filter system rather than disposable cartridges. This means you should expect to periodically wash the filters rather than pay for ongoing replacement costs, which is a meaningful long-term saving over purifiers with consumable HEPA filters. Check the manual for wash frequency guidance, as running it in a dusty or high-pollution environment will require more regular maintenance.

This purifier is well suited to allergy sufferers, pet owners, or anyone dealing with household dust and odours in a medium-sized room, where its multi-stage filtration is designed to capture particles and neutralise smells effectively. It works best as a dedicated room unit rather than being moved frequently between large spaces, so buyers expecting whole-home coverage from a single unit will likely find it underwhelming. Those living in smaller flats or single rooms will get the most consistent performance from it.

This product has only recently been tracked, so there is no historical price data to confirm whether £169.99 represents the lowest it has ever been listed or simply a temporary promotion. What can be said is that the listed saving of £80 off a £249.99 RRP is a 32% reduction, and at this price point it sits competitively within the mid-range air purifier market. Buying now is a reasonable call given the discount is meaningful, but if you can wait a few weeks, checking back will give a clearer picture of whether this price holds or dips further.

The Levoit Core 300 is typically available for around £60–£80, making it substantially cheaper, but it uses a replaceable True HEPA filter that adds ongoing cost and lacks the washable multi-stage system the Shark offers. The Shark NeverChange5 at £169.99 justifies its higher upfront price primarily through the no-replacement-filter design, which suits buyers who want to avoid recurring expenses, whereas the Core 300 suits those prioritising a lower entry cost and proven HEPA certification. If long-term running costs matter to you, the Shark is the stronger choice; if you want a compact, low-cost unit with widely validated performance, the Levoit is worth considering.
