How we chose

How we chose: We compared tank size, stated coverage, noise rating and current price across the Levoit line to match each unit to a room size and budget.

Tank size separates the small units from the large ones. The Classic 160 holds 2.5 L, the Classic 300S, LV600S and OasisMist 600S each hold 6 L, and the Superior 6000S holds 22.7 L. Stated coverage runs from 430 sq ft for the OasisMist 600S and 505 sq ft for the Classic 300S, through 430–753 sq ft for the LV600S, up to 3,000 sq ft for the Superior 6000S. The Classic 160 lists no coverage figure.

Noise ratings are close where they are given: 28 dB for the Classic 160 and the Superior 6000S, 30 dB for the Classic 300S. Current prices span $39.99 for the Classic 160, $71.99 for the Classic 300S, $109.99 for both the LV600S and the OasisMist 600S, and $249.99 for the Superior 6000S. The Classic 300S costs $32.00 more than the Classic 160; the LV600S and OasisMist 600S each cost $70.00 more than the Classic 160 and $38.00 more than the Classic 300S; the Superior 6000S costs $210.00 more than the Classic 160 and $178.00 more than the Classic 300S.

Who should skip these

If you only need a small bedside unit, skip the larger tanks and higher prices. The Classic 300S is $71.99, the LV600S and OasisMist 600S are $109.99 each, and the Superior 6000S is $249.99 — each costs more than the 2.5 L Classic 160 at $39.99. The Classic 300S costs $32.00 more than the Classic 160, the LV600S and OasisMist 600S each cost $70.00 more, and the Superior 6000S costs $210.00 more. A 6 L or 22.7 L tank is more capacity than a nightstand needs.

If you are humidifying an open living area, skip the compact Classic 160. Its 2.5 L tank is the smallest here, and at $39.99 it is the least expensive, but it is not built for a full room. The Classic 300S covers 505 sq ft, the LV600S covers 430–753 sq ft, the OasisMist 600S covers 430 sq ft, and the Superior 6000S covers 3,000 sq ft.

How to choose the right one

Start with the room, not the price. The Classic 160 has a 2.5 L tank and no stated coverage, so we treat it as a nightstand or desk unit. The Classic 300S covers 505 sq ft with a 6 L tank, which suits a bedroom or living room. If your space runs larger, the LV600S lists 430–753 sq ft and the OasisMist 600S lists 430 sq ft, both with 6 L tanks. The Superior 6000S is the outlier: 3,000 sq ft and a 22.7 L tank.

Then weigh the gaps. At $39.99, the Classic 160 is the cheapest. The Classic 300S is $32.00 more; the LV600S and OasisMist 600S are each $70.00 more than the Classic 160 and $38.00 more than the Classic 300S, and they cost the same as each other. The Superior 6000S is $210.00 more than the Classic 160 and $140.00 more than either 6 L smart model.

A bigger tank means fewer refills. If you would rather fill once and forget it, the 22.7 L tank justifies the jump; if you refill anyway, the smaller tank is fine.
