Dreo Air Purifier 338S vs Shark BreatheClear Compact Pro (HP062GN)
On the 4.8 air-change basis the Dreo 338S suits a bedroom or home office of about 178 square feet, close to three times the space Shark rates the BreatheClear Compact Pro for. Both are app-connected purifiers with sensors and auto modes, but the Shark is a nursery or desk-corner machine, and the figure on its box, several times larger, is the wrong number to plan a room around.
At night the Dreo goes down to 18 dB in sleep mode, close to silent. Shark lists no decibel figure for the Compact Pro, so a light sleeper who needs a number before buying will end up with the Dreo.
The Shark's main filter is rated for six years behind a washable pre-filter, which makes the purchase price most of what the machine will ever cost. It is sold on a capture rate and carries no rated HEPA class, a point allergy buyers will want to weigh. The 338S pairs a True HEPA layer with activated carbon and has a reminder that lights when the filter is due.
The Shark reacts to VOCs and odors as well as particles, turns itself down at night on a light sensor, and shows its reading on a round display you can read from across a room. The 338S answers with voice control, so it can be switched or scheduled without picking up a phone.
Editor’s note
Six fan speeds and a timer cover a bedroom's needs on the 338S, and the app is good enough to justify the S over the plain 338. Dreo quotes 115 CFM, which it calls a CADR, and its 856 square foot box claim is a one-air-change number that misleads anyone furnishing a living room. Dreo gives no filter interval, wattage or weight, so price a replacement filter before you commit.
A long filter life stops a cheap purifier from becoming an expensive one, and sensing that reacts to cooking smells and darkness makes the Compact Pro a machine you stop touching. For its tiny brief it is the more thoughtful design of the two, and I'd choose it for a nursery on those grounds alone.
Head-to-head points: every spec is scaled between these products only, so a product can score high here and modestly on its own page, where the VS Score measures it against the median of its class.

What reviewers say
The bottom line
Pick the 338S for nearly any adult bedroom or home office, because it can clean a room of ordinary size and its low floor suits a sleeper.
The Compact Pro earns its place in a nursery or a small study of about 62 square feet. There, its odor and light sensing and its long filter interval suit a parent who wants to buy once and stop thinking about consumables. Stretched across a larger room it runs flat out without keeping pace.
