AlorairCrawlspace FAQ

AlorAir coupon and buying guide

Choose the right AlorAir dehumidifier before using a coupon

AlorAir focuses on moisture-control equipment for crawl spaces, basements,
whole-house applications, workshops and restoration work. Before applying
a coupon code, compare AHAM capacity, saturation capacity, coverage,
drainage, filter type and smart-control features.

%

Check the complete project cost

A discount is useful only when the unit is correctly sized. Include the
drain route, condensate pump, replacement filters, risers, hanging
hardware, vapor barrier or ventilation fan when calculating the full
moisture-control setup.

Start with the moisture problem, not the model number

The same-looking dehumidifier can behave very differently in a tight
crawl space, a finished basement or a whole-home duct system.

Low-clearance crawl space

Prioritize compact dimensions, auto-defrost and a practical drain path.

Up to about 1,300 sq. ft.

Compare the 35–55 PPD AHAM class and match gravity drainage or a pump to the site.

Large basement or crawl space

Higher-capacity units can reduce the need for multiple machines.

Remote monitoring

Wi-Fi models are useful when the equipment is installed in a rarely visited area.

Whole-house humidity

Compare airflow, filters and ducting requirements instead of room coverage alone.

AlorAir model comparison by specifications

AHAM and saturation figures use different test conditions, so they should
not be treated as interchangeable.

ModelMoisture removalSuggested coverageDrainage / controlsBest fit
Helios D3535 PPD AHAM
70 PPD saturation		Up to 1,000 sq. ft.Gravity drainage
Auto-defrost		Compact crawl spaces and smaller basements
Sentinel HD35P35 PPD AHAM
70 PPD saturation		Up to 1,000 sq. ft.Condensate pump and hose
Auto-defrost		Areas where water must be lifted to a drain
Sentinel HD35P WiFi35 PPD AHAM
70 PPD saturation		Up to 1,000 sq. ft.Pump and hose
App monitoring and control		Remote properties or hard-to-access crawl spaces
Sentinel HD55S55 PPD AHAM
120 PPD saturation		Up to 1,300 sq. ft.Gravity drainage
MERV-1 filter		Medium-size crawl spaces and basements
Galaxy 6060 PPD AHAM
145 PPD saturation		Up to 1,800 sq. ft.Gravity drainage
MERV-1 filter		Larger enclosed crawl spaces and basements
Sentinel WHD 10090 PPD AHAM
70 PPD DOE		Up to 2,300 sq. ft.Whole-house format
MERV-10 filter and auto-defrost		Whole-home humidity systems and ducted projects

Verify the latest specification sheet, electrical requirements,
installation clearance and drainage method for the exact configuration.

The hidden fit test

1

Access and service space

Measure the opening, doorway and clearance needed to remove the filter.

2

Drain direction

Gravity drainage and pump-assisted drainage solve different layouts.

3

Climate conditions

Check the expected temperature and humidity range.

4

Maintenance routine

Plan filter access, cleaning intervals and safe inspection access.

AlorAir ordering checklist

  • 1
    Measure the area, ceiling height and equipment access route.
  • 2
    Compare AHAM ratings before saturation figures.
  • 3
    Decide whether gravity drainage or a condensate pump is required.
  • 4
    Choose Wi-Fi control when remote monitoring is genuinely useful.
  • 5
    Confirm voltage, outlet access and cord length.
  • 6
    Add filters, risers, hardware or vapor-barrier materials to the final budget.
Follow the product manual and local electrical requirements. Keep airflow
openings clear and confirm delivery, return and warranty terms before
ordering heavy equipment.

AlorAir coupon and dehumidifier FAQ

What does AlorAir sell?

AlorAir sells crawl-space and basement dehumidifiers, whole-house
units, ventilation fans, filtration systems, filters, vapor
barriers, accessories and combination moisture-control kits.

Compare AHAM capacity, recommended square footage, dimensions,
temperature range, airflow, filter type, drainage method and the
accessories required for your space.

AHAM capacity is usually the better starting point because it uses a
standardized operating condition. Saturation capacity represents a
much wetter test environment.

A pump is useful when the drain is higher than the unit or too far
away for gravity flow. A nearby lower floor drain may not require a
pump.

Wi-Fi control is helpful when the crawl space is difficult to visit.
Remote monitoring can reveal a power interruption, unusual humidity
or a drainage problem.

Choose a crawl-space model for a contained under-floor or basement
area. Consider a whole-house model when the project includes central
airflow, ducting and several living zones.

Confirm the exact model, dimensions, electrical supply, drainage
arrangement, delivery access, installation responsibility, filter
availability and current return or warranty terms.
