Why the list stops at two

Pump-equipped machines can also offer gravity drainage, but this page selects documented non-pump models. The shared Shield manual reserves pump operation for 60P and 85P; ambiguous live-table wording does not turn Shield 60 into a pumped model.

Neither candidate is an automatic recommendation based on floor area alone. Resolve the moisture-load assessment before paying for greater rated capacity. The 70- and 145-pint headlines describe saturation values, not the equivalent-condition figures in the table.

When to leave this shortlist

If tracing the hose reveals an uphill section, return to the drain-route decision rather than forcing a gravity-only choice. If gravity works but another model offers a better verified fit or offer, there is no evidence here that an unused internal pump necessarily makes it worse. We have not established a price or reliability advantage from the absence of a pump.

What to know

  • Gravity only
  • 35 pints/day — 80°F / 60% RH
  • 15.35 × 11.2 × 11.4 in

Best if

  • You can provide the downhill route whose absence caused the reported installation difficulty.
  • Your fixed location tolerates the reported variability in perceived noise.

Skip if

  • The outlet requires a rise or the control presets do not match your monitoring plan.

The 35M is the simpler compact candidate when its presets and assessed capacity suit the space. William’s favorable humidity result is tempered by his noise observation; Matthew’s above-grade outlet issue makes drain geometry a condition of selection. Read the model review.

What to know

  • Gravity; shared manual reserves pump operation for 60P/85P
  • 60 pints/day — 80°F / 60% RH
  • 21.3 × 12.8 × 14.6 in

Best if

  • You can leave the unit in an accessible position and the assessed load supports the higher rated class.

Skip if

  • You expect easy frequent relocation.
  • You are relying on a mixed-model review to obtain a built-in pump.

The 60 is a candidate for a justified capacity step with room for a larger cabinet. Edward’s dolly suggestion and the small-display complaint favor an installation you can service without repeatedly moving the machine. Read the Shield 60 review.

Choose the capacity after the downhill route

35M: compact preset control

Choose 35M where the compact cabinet, presets and rated capacity meet the task.

Shield 60: a justified larger load

Consider Shield 60 for a justified larger load and an accessible permanent position.

When drainage changes the list

If any part of the drain must rise, pause this gravity-only shortlist and revisit pump versus gravity drainage. Neither machine should be selected by averaging contradictory coverage claims or borrowing features from a P variant.

Frequently Asked Questions

Can pump-equipped dehumidifiers also gravity-drain?

Some can, including documented models in this project. This shortlist intentionally examines the researched non-pump candidates.

Does a gravity-only unit guarantee better reliability?

No. Fewer installed features do not establish comparative service life without appropriate evidence.
