Santa Fe Compact70 vs AprilAire E080: Which Fits Your Space?

These two units aren’t really competing for the same job

It’s tempting to line up the Santa Fe Compact70 and the AprilAire E080 as direct rivals, but they’re built around different priorities, and picking well starts with recognizing that. The Compact70 is a small-footprint unit — a 12-inch-wide, 21-inch-deep, 12-inch-high cabinet weighing 55 pounds, rated at 70 pints per day at the AHAM condition of 80°F and 60% relative humidity, with a manufacturer-claimed coverage of 2,600 square feet. The E080 is the bigger machine in every dimension: a 14-by-26-by-15-inch cabinet at 63 pounds, rated at 80 pints per day at the same AHAM condition, with a claimed coverage of 4,400 square feet. The side-by-side table above lays out every spec; the rest of this comparison is about what those differences mean in an actual crawl space.

Footprint and fit favor the Compact70

If your crawl space has tight clearance — and many do — the Compact70’s 12-inch height is the number that can decide the whole purchase. A unit that won’t slide under the joists can’t dry anything, and at 55 pounds the Compact70 is easier to maneuver into an awkward space than the taller, heavier E080. The E080’s 15-inch height and larger cabinet are the physical cost of its bigger capacity and coverage. So the first question isn’t which unit is better, it’s which one fits: measure your clearance before anything else, because that constraint can settle the decision on its own.

Capacity and coverage point the other way

If clearance isn’t your bottleneck and the space is genuinely large, the E080’s higher capacity and much larger claimed coverage — 4,400 square feet against 2,600 — are the reason to choose it. An undersized unit in a big, damp space just runs longer to chase a humidity target it can’t quite hold, which costs you in both wear and electricity. That said, treat both coverage claims as starting points rather than guarantees: each is built on the manufacturer’s own assumptions, and your real number depends on volume, climate, and site conditions. Run your space through our sizing calculator before you let either coverage figure make the call.

Both give you a real running cost — by different routes

Both of these units let us put a verified number on the electric bill, but they get there differently, and it’s worth understanding why. The Compact70 publishes a rated wattage — 580 watts, drawing 5.1 amps, with an energy factor of 2.4 liters per kWh — so we estimate its cost our usual way: watts divided by 1,000, times an assumed 12 active hours a day (a 50% duty-cycle assumption, since the compressor cycles rather than running continuously), times 30 days, times the months you run it, times your rate. The E080 doesn’t publish a wattage, but it’s ENERGY STAR certified, so the EPA gives us a DOE-measured annual energy figure instead — 632 kWh per year — which we simply multiply by your rate.

The catch is that these two figures aren’t a clean apples-to-apples comparison, and we won’t pretend they are: the Compact70’s number is our seasonal estimate built on a duty-cycle assumption, while the E080’s is a standardized full-year measured value. They answer slightly different questions, so stacking them as a straight “this one’s cheaper” claim would be misleading. What genuinely matters here is that neither leaves you guessing — both are grounded in real data, which many units in this category can’t say. Run each through the operating cost calculator with your own rate to see each unit’s figure on its own terms.

Filtration and noise swing back to the E080

The trade runs the other direction on two specs the Compact70 leaves blank. The E080 uses a MERV-8 filter and publishes a 45 dBA noise level; the Compact70’s data sheet verifies neither its filter’s MERV rating nor its decibel level. In a crawl space under a quiet room, or in a space where air cleanliness matters as much as moisture, the E080’s documented MERV-8 filtration and known noise figure are a genuine advantage — not because the Compact70 is necessarily worse, but because we can’t tell you what its numbers are, and the E080’s are on paper.

The specs where they’re close

A few differences are real but small. Both run cold to nearly the same floor — the Compact70 to 49°F, the E080 to 50°F — so neither is a standout for a bitterly cold crawl space, and the one-degree gap isn’t worth weighing heavily. Both drain by gravity with no pump included, so if your drainage needs a lift, you’re buying a separate pump either way. The warranties differ modestly: six years on the Compact70, five on the E080. And we don’t have a verified street price for either, so check the retailer links directly and budget a pump into whichever you choose if your drain point sits above the unit.

Which one we’d pick

There isn’t a single winner here, and pretending otherwise would do you a disservice. For a small, tight, low-clearance crawl space, the Santa Fe Compact70 is the better-matched unit, and its longer warranty is a bonus. For a large crawl space where the extra capacity and coverage earn their keep, and where documented filtration and a known noise level matter, the AprilAire E080 is the stronger choice — and with its ENERGY STAR–measured energy figure, its running cost is now just as verifiable as the Compact70’s, so that’s no longer a point of separation. Size your space first, confirm your clearance, and let the specific gap that matters most to you — footprint and warranty, or capacity and filtration — break the tie.
