tapOur recommendation
Choose AprilAire E080 for a balanced 80-pint whole-home or basement installation where its smaller capacity is enough and you value the control and ducting ecosystem. Choose Santa Fe Oasis105 when the space is larger, cooler or needs more published airflow and moisture removal. Both require a deliberate drain plan; neither has an internal condensate pump.
Sylvane displayed both products as backordered when checked. Prices and package contents can change.
| If this sounds like you | Best next move | What decides it |
|---|---|---|
| Typical whole-home or large-basement plan | AprilAire E080 | 80-pint capacity and flexible installation are the balanced choice. |
| Larger or cooler moisture load | Santa Fe Oasis105 | Higher published output and operation down to 49°F. |
| Drain must rise | Neither by itself | Add the correct condensate-pump package and alarm strategy. |
| Water is entering the building | Fix the source first | Neither machine stops bulk water. |

Quick verdict
E080 is the easier default when 80 pints per day is enough and the installer prefers AprilAire controls and ducting. Oasis105 earns its higher price when the extra airflow, cool-room specification and published low-temperature capacity solve a real need.
This is not a laboratory comparison. We have not operated the two machines side by side, so we do not claim a winner for measured noise, actual energy use or extraction in your basement.
| Decision | E080 | Oasis105 |
|---|---|---|
| Published capacity | 80 pints/day | 105 pints at 80°F; 67 at 65°F |
| Airflow | 185 CFM | 280 CFM |
| Drainage | Gravity; pump in selected package | Gravity/positive pressure; optional pump |
| Published low-temperature operation | Confirm for exact installation | 49°F |
| Best reason to choose | Balanced system fit | More capacity and airflow |
Capacity: use the room, not the model number
The 25-pint headline gap matters only if the room creates enough moisture to use it. Measure temperature and relative humidity, note whether doors stay closed and document recent leaks or flooding. A large square-foot claim can hide differences in climate, air sealing and water entry.
Oasis105 is unusually helpful because it also publishes 67 pints/day at 65°F/60% RH. That cooler-condition figure may be more useful in a basement than the 80°F result. Ask the E080 installer for a sizing basis that reflects your conditions.
Air movement and ducting
AprilAire lists 185 CFM for E080; Sylvane lists 280 CFM for Oasis105. Higher airflow can help a larger open space, but it can also demand a more careful duct layout and may be unnecessary for a small room.
Ask the installer to show the proposed return and supply path, external static pressure allowance and how closed rooms will exchange air. A machine cannot control a shut-off area simply because its catalog coverage number is large.
Drainage and pump planning
Both machines are designed for continuous drainage. If a suitable drain sits lower than the outlet, gravity is the simplest plan. If the line must rise, specify a compatible condensate pump, lift height, overflow protection and a serviceable location.
The AprilAire basement package sold by Sylvane can include an external pump. Oasis105 uses gravity or an optional pump. Compare the package contents rather than assuming the base listing includes every drain part.
Controls and daily use
E080 has built-in digital control and can be integrated into a ducted system with compatible controls. Oasis105 uses onboard humidity control and is positioned for standalone or ducted moisture control.
Decide who will change the setpoint, check the drain and clean the filter. Remote monitoring is useful only if it is included in the exact package and someone will act on an alert.
Cabinet fit, sound and electrical load
Measure the route into the basement, the final footprint and service clearance. AprilAire lists the E080 around 15 by 14 by 26 inches and 5.1 amps at 110–120V. Sylvane lists Oasis105 at 54 dB and 540 watts.
Those figures are useful for planning, not a promise of perceived sound or monthly cost. Use the local electricity rate and expected duty cycle for an estimate, and keep the unit out of a flood path.
Price the complete installation
At our check, Sylvane displayed about $1,650 for E080 and $2,249 for Oasis105, with both shown as backordered. Add the pump, duct parts, controls, electrical work, filters, mounting and labor before judging the price gap.
Oasis105 should not win simply because it is larger. Pay the premium when the load, temperature or airflow needs it. E080 should not win simply because it is cheaper if it would run continuously and still miss the target.
Who should choose each model?
Choose E080 when an 80-pint unit is supported by the sizing work, the installation benefits from AprilAire controls or ducting, and a gravity or packaged-pump drain is practical. Choose Oasis105 for a demanding large or cool space when its published capacity and airflow provide justified headroom.
Choose neither until an active leak, groundwater route or sump failure has been addressed. A dehumidifier is moisture-control equipment, not a waterproofing system.
AprilAire E080 vs Santa Fe Oasis105: the bottom line
E080 is the balanced choice; Oasis105 is the capacity-first choice. The deciding evidence is your temperature, humidity, drain route and installer’s duct plan—not the largest coverage number.
Ask for the exact package SKU and written installed scope. That prevents a comparison between a bare unit and a complete package.
Frequently asked questions
Which should I choose in the AprilAire E080 vs Santa Fe Oasis105 comparison?
Choose AprilAire E080 for a balanced 80-pint whole-home or basement installation where its smaller capacity is enough and you value the control and ducting ecosystem. Choose Santa Fe Oasis105 when the space is larger, cooler or needs more published airflow and moisture removal. Both require a deliberate drain plan; neither has an internal condensate pump.
What should decide the comparison?
Typical whole-home or large-basement plan: aprilaire e080. 80-pint capacity and flexible installation are the balanced choice.
What should I do before ordering?
Ask two installers to size the moisture load and quote the same drain, duct and control scope.
