Our take on the AlorAir Sentinel HD35P Dehumidifier

The AlorAir Sentinel HD35P is a crawl space and basement dehumidifier rated at 35 pints per day under AHAM conditions and up to 70 pints at saturation. It uses LGR (low-grain refrigerant) technology, a MERV-1 filter, automatic defrost and a memory function that restarts the unit after a power cut. It is built for tight, damp spaces up to about 1,000 sq ft, and it drains by gravity or with a built-in pump. Against typical portable home dehumidifiers it is a compact, install-style unit with a pump and low-temperature defrost rather than a rolling bucket appliance; owners of this class of unit tend to value the pump and continuous drain, and to note the noise and the need to set up drainage.

Best forDamp basements and crawl spaces up to about 1,000 sq ftGarages, storage rooms and other unheated spacesOwners who want a built-in condensate pumpSet-and-forget operation with auto restart after outages
Pros
  • Built-in pump plus gravity drain gives two drainage options
  • Automatic defrost keeps it running in cold spaces
  • Memory function resumes operation after a power outage
  • MERV-1 filter traps dust and protects the coil
  • Compact footprint for a crawl space or tight corner
  • Rated below 55 dB during operation
Cons
  • 35-pint AHAM rating is modest for very large or very wet spaces
  • Pump and compressor noise is noticeable in living areas
  • Filter is basic MERV-1, not a fine particle filter
  • Needs a drain line or pump hose routed to a drain

About the AlorAir Sentinel HD35P Dehumidifier

The AlorAir Sentinel HD35P is a 70-pint dehumidifier for basements, crawl spaces, storage areas, garages, large rooms and commercial settings. It covers spaces up to 1,000 sq. ft. It removes up to 70 pints of water per day at 90°F and 90% relative humidity, and 35 pints under AHAM conditions (80°F, 60% RH).

It uses LGR technology to control air humidity. A MERV-1 filter captures dust to help protect the unit's internal components. An automatic defrost function lets it run in low-temperature environments.

The unit can drain by gravity or with its built-in pump. A memory function restarts it automatically after a power interruption. Noise is below 55 decibels in operation, with a sound pressure level of 50 dBA.

Questions and answers

Is the HD35P big enough for a full basement?
It is rated for spaces up to about 1,000 sq ft. Larger or very wet basements may need a higher-capacity unit or a second one.
Does it need to be emptied?
No. It drains by gravity hose or with its built-in pump, so there is no bucket to empty.
Will it work in a cold crawl space?
Yes. Automatic defrost lets it keep running in low temperatures where coils would otherwise ice up.
What filter does it use?
A MERV-1 filter that captures dust and protects the internal components. It is a basic filter, not a fine particle one.
How loud is it?
The rated noise is below 55 dB. Owners describe it as noticeable, so it suits utility spaces better than living rooms.
What comes in the box?
The unit, its MERV-1 filter and a power cord. A drain hose for gravity or pump drainage is typically needed and is not always included.
