If you want the simplest, lower-maintenance pick, I’d lean Shark NeverChange. If you want a more app-friendly, smart-home-oriented purifier, I’d lean Levoit Core 400S.

My short take: buy the Shark if convenience and less upkeep matter most; buy the Levoit if connected controls matter more.

I can’t verify the exact feature claims for the current versions or retailer listings, and those details can change over time, so it’s worth checking the latest product pages before you buy.

Alternatives

A more compact and budget-friendly alternative to the Core 400S, ideal for smaller bedrooms up to 219 sq ft.
Levoit Core 300S
Saves money and space if you don't need the high CADR/room coverage of the Core 400S.
A powerful multi-fan air purifier from Shark that uses standard filters (replaced annually) but offers high-volume air delivery for extra-large spaces.
Shark Clean Sense 500
Good if you want Shark's build quality but prefer a traditional, slimmer tower design over the bulky NeverChange body.

What could change this answer
