The catch
Shark NeverChange Air Purifier MAX
The up-to-five-year claim is based on a 300-square-foot room and 12 hours of operation a day. More demanding use can cut that life short.
Side by side
Shark HP302 vs Dyson BP06: Shark changes fan speed on its own, BP06 leaves the controls to you
Quick verdict
Around pets the Shark is easier to automate and to maintain. The Dyson is more specialized for formaldehyde and gases, though it gives up sensors, Auto mode and app control.

What this page compares
Sensing, gas treatment, controls, upkeep and price set these long-life-filter purifiers apart.
This one comes down to automation and gas treatment first, then to the limits of your own setup.
Day to day
How each one fits your routine
Five years and 21,900 hours are measured on different clocks
Shark's main-filter claim of up to five years assumes a 300-square-foot room and 12 hours of daily use. Dyson specifies 21,900 hours for its HEPA element, which works out to about 2.5 years at 24 hours daily or five years at 12 hours daily. If you run the purifier around the clock, don't compare the headline years directly. Check the usage assumptions and the separate carbon replacement schedule before choosing.
Where this comes from
21,900 divided by 24 and then 365 gives 2.5 years, or five years at 12 hours daily. These convert rated time into years and do not guarantee anything under heavy smoke, fur or dust.
A steady fan speed and an automatic response suit different rooms
The particle sensor in the HP302 can change the fan as air conditions shift. BP06 has two manually selected speeds and lacks the Auto and app functions found on other Dyson models. Choose BP06 if a steady selected setting matters during calls and you will adjust it yourself when needed. Choose Shark if automatic particle response matters more, and accept that the response can change the sound while it runs.
Where this comes from
The point here is control behavior and not a measured winner on sound. The Big+Quiet name does not show comparative sound at equal particle delivery, and BP06 should not be credited with sensors from a different Dyson purifier.
