What to know about AIRCARE H12600 Alliance

A 5.4-gallon whole-house console rated for 3,700 sq ft and about 45 hours per fill, with 4 speeds, a 25–65% humidistat, auto shut-off and casters. It was the most powerful unit in Bob Vila's test and its 'Best Whole-House' pick.
Editorial notes

Why it stands out

Why we like it

It was the most powerful unit in Bob Vila's evaporative test and its Best Whole-House pick. The big reservoir means infrequent refills, and the humidistat and auto shut-off handle the rest.

It is simple, with no app, and it is priced below the Levoit 6000S.

What to know

Skip it if you want easy cleaning or a quiet room. The tank interior can't be scrubbed and it reaches about 60 dB on high. Amazon sells it through a third-party seller, so check Walmart or Target for alternatives and confirm the warranty.
