9 Best AlorAir Dehumidifiers for Basements (November 2026)
The best AlorAir dehumidifiers for basements include the ALORAIR 113 Pints Crawlspace Dehumidifier for Commercial for most basements, the ALORAIR 170 PPD Commercial Dehumidifier with Pump for large basements, and the ALORAIR 120 Pints Energy Star Crawlspace Dehumidifier for energy-conscious operation.
On this page (5 sections)
The best AlorAir dehumidifier for most basements is the Sentinel HD55, because its 53 PPD AHAM capacity, automatic drainage and 1,200 sq. ft. coverage fit many everyday basement layouts.
That balance matters more than chase the largest number on the box. A basement unit runs for long stretches, so drainage, placement and controls shape how easy daily use feels.
Choose a pump model when water must travel upward to a drain. Choose a larger commercial unit for a very large space or a room that stays wet after a leak.
For a high-capacity basement setup, compare commercial basement dehumidifiers.
Basement shoppers should compare the AHAM moisture-removal figure, not only the larger saturation number.
Saturation conditions are warmer and wetter than many basements. The AHAM figure gives a steadier basis for comparing models side by side.
Drainage, floor area, clearance and control style matter just as much as capacity.
A unit that cannot drain well will be a chore. A unit that is too large for the route downstairs can also become a chore.
Measure the room and trace the hose path before you choose. Leave space around the intake and outlet so the machine can move air without strain.
Think about who will use it and how often. A storage basement, a finished room and a utility corner all place different demands on the same machine.

Which AlorAir dehumidifiers are best for basements?
The best AlorAir dehumidifiers for basements separate into 3 groups: compact gravity-drain units, mid-size models with stronger capacity, and large pump-equipped machines. For another brand, compare Santa Fe basement dehumidifiers.
Your drain path and basement size should decide which group you need.
Our score weighs specs, features and buyer feedback against what you're shopping for. We checked the stated capacity, coverage, drainage, controls, placement details and everyday care needs.
ALORAIR 113 Pints Crawlspace Dehumidifier for Commercial: Best for most basements
- 53 PPD AHAM capacity
- Up to 1,200 sq. ft.
- Automatic drainage
- Metal casing
The Sentinel HD55 combines strong basement capacity with a compact metal body, automatic drainage and automatic defrost.
Pros
- High AHAM moisture removal
- No internal tank to empty
- Metal outer casing
Cons
- No built-in pump
- Remote control is optional
The Sentinel HD55 is the strongest general pick because it balances capacity and size.
It removes 53 pints per day at AHAM conditions, with a larger 113-pint saturation figure, and is rated for spaces up to 1,200 sq. ft.
Its metal outer casing suits a basement or crawl space where the unit may face tougher conditions than a living room appliance.
That casing also helps with knocks during placement or service. It will suit shoppers who want a fixed unit rather than a light portable appliance.
Automatic drainage means there is no internal tank to empty every few hours.
You still need to plan the hose route with care. Set the outlet lower than the unit and check for kinks during the first days of use.
The 120 CFM airflow, automatic defrost and MERV-1 filter support routine operation.
The filter helps keep dust away from internal parts. Keep it clean so airflow does not fall over time.
The 19.2 x 12.2 x 13.3 in body is compact enough for many low basement areas.
Measure your route and service clearance first. You will need room to reach controls and to lower the unit for cleaning.
This model uses gravity drainage, so the hose needs a suitable downhill path.
If your floor drain is higher than the unit, choose one of the pump models below instead.
It suits homeowners with a nearby drain and a stable corner for a fixed unit. It is less suited to a basement where water must be lifted a long way.
ALORAIR 170 PPD Commercial Dehumidifier with Pump: Best for large basements
- 80 PPD AHAM capacity
- Up to 2,100 sq. ft.
- Built-in pump
- 19.6 ft drain hose
The Storm 80X is sized for larger spaces and adds a built-in pump for flexible drainage.
Pros
- Largest AHAM capacity in this group
- Built-in pump
- Wheels and retractable handle
Cons
- Heavier 63.9 lb body
- Commercial capacity may exceed small basement needs
The Storm 80X is the best choice for a large basement that needs pump drainage.
It removes 80 PPD at AHAM conditions and covers up to 2,100 sq. ft. That headroom suits open basements, workshops and rooms with heavy damp.
The built-in pump includes a 19.6 ft drain hose.
That makes placement easier when water cannot flow downhill to a nearby drain. Measure the path so the hose does not run beyond what the pump can handle.
Its 200 CFM airflow, wheels and retractable handle suit a machine that may need to move between areas.
The rotomoulded plastic housing is impact-resistant, which suits storage or work areas.
The 15.2 x 14.4 x 24.8 in body takes more floor space than compact models. Plan the spot first and keep the intake clear.
Automatic defrost, auto on/off, memory restart and power recovery reduce the need to reset it after interruptions.
At 63.9 lb, plan the route downstairs. Get help on narrow or steep stairs.
ALORAIR 120 Pints Energy Star Crawlspace Dehumidifier,: Best for energy-conscious operation
- 55 PPD AHAM capacity
- Up to 1,300 sq. ft.
- Energy Star certified
- Metal housing
The Sentinel HD55S adds Energy Star certification and slightly higher stated capacity than the HD55.
Pros
- Energy Star certified
- Metal housing
- Automatic defrost
Cons
- No built-in pump
- Remote monitoring is optional
The Sentinel HD55S is a good fit when you want a metal-bodied unit with Energy Star certification.
It removes 55 PPD at AHAM conditions, covers up to 1,300 sq. ft. and reaches 120 pints at saturation.
That makes it a close fit for the HD55 in daily use. The choice often comes down to certification and the exact controls you want.
Its dimensions match the HD55 at 19.2 x 12.2 x 13.3 in, so it can work in a similar basement footprint.
If you have already planned a corner for a compact unit, this size helps. Measure doorways and low beams before you buy.
The 130 CFM airflow and automatic defrost are suited to regular humidity control in cooler lower-level spaces.
Defrost matters when the basement stays cool for long periods. The fan keeps running while frost clears, then normal drying resumes.
Continuous drainage removes the need to empty a tank.
You do need a drain that sits below the unit. Run the hose so it slopes all the way down without dips.
This model does not include a built-in pump.
Plan for a downhill hose route before choosing it. If that route is not possible, a pump model will be easier to live with.
The MERV-1 filter helps protect internal components from dust.
Check it on a regular schedule. A dusty basement will need more frequent care than a clean one.
If you want remote control, check the specific setup because optional remote compatibility is described separately from the base unit.
That extra step only suits shoppers who will use it. A nearby basement may not need remote access at all.
ALORAIR Hanging Kits for Crawl Space: Best for suspended placement
- 4 ratchet straps
- Supports up to 300 lb
- Adjustable pulley system
- Zinc-plated stainless steel hooks
This kit helps raise compatible AlorAir units from the floor in crawl spaces or basement areas.
Pros
- Adjustable height
- Can help reduce floor vibration
- Makes service access easier
Cons
- A placement accessory, not a dehumidifier
- Compatibility must match your unit
The AlorAir Hanging Kits for Crawl Space suit basements or crawl spaces where raising a compatible dehumidifier off the floor helps placement.
This is an accessory, not a moisture-removal unit. It will not add drying power on its own.
The pack includes 4 ratchet straps with an adjustable pulley system.
That lets you raise or lower the unit to a set height for cleaning or service.
The polypropylene rope and zinc-plated stainless steel hooks support up to 300 lb.
Check the weight of your exact model before you start.
Suspending a unit may create height for condensate drainage.
Extra height can make a gravity drain run more cleanly and keep the unit clear of puddles or stored items.
It can reduce noise or vibration transfer when installed correctly.
That may help when a basement sits below bedrooms, though results depend on joists and fixing points.
It can also make lowering the unit for service easier. Keep a clear work area where you can reach it safely.
The kit names several compatible Sentinel models, including the HD55 and HD55S.
Choose solid joists and keep straps level. It suits a low crawl space where floor space is tight, less so a finished basement with a stable floor spot.
ALORAIR 70 PPD Dehumidifier with Pump: Best for hard-to-drain basements
- 35 PPD AHAM capacity
- Up to 1,000 sq. ft.
- Built-in pump
- 19.6 ft hose
The Sentinel HD35P fits smaller basements where a built-in pump matters more than maximum capacity.
Pros
- Pump supports upward drainage
- Compact body
- Automatic defrost
Cons
- Lower AHAM capacity than larger picks
- MERV-1 filter
The Sentinel HD35P is the best AlorAir dehumidifier for a smaller basement where the drain point is difficult to reach.
It removes 35 PPD at AHAM conditions, reaches 70 pints at saturation and covers up to 1,000 sq. ft.
That suits a compact basement with steady damp. It will not match larger commercial models on drying power.
Its built-in condensate pump can lift water up to 19.6 ft vertically, with a 19.6 ft drain hose.
You can place it in a low corner and send water to a higher outlet. Keep the route as short and straight as you can.
The 15.2 x 11.2 x 11.4 in body is compact for a narrow utility area. Measure the corner before you commit.
At 38.2 lb, stairs still need planning. A second person can help on the way down.
Automatic defrost and auto restart support unattended operation. The unit can resume after temperature changes or power interruptions.
AlorAir states operation stays below 50 dB. Keep the intake and outlet clear so air can move.
The MERV-1 filter helps protect internal components. Clean it as dust builds up.
The simple control panel suits shoppers who want to set a target and leave it.
ALORAIR Smart Wi-Fi 120 Pints Energy Star: Best for remote monitoring
- 55 PPD AHAM capacity
- Up to 1,300 sq. ft.
- Wi-Fi app control
- Energy Star certified
The Wi-Fi model suits basements you don't visit often because you can monitor humidity and adjust settings remotely.
Pros
- App control
- Energy Star certified
- Continuous drainage with included hose
Cons
- Wi-Fi features may be unnecessary for a nearby basement
- MERV-1 filter
The Sentinel HDi65S Wi-Fi model suits a basement that you do not check every day.
It combines 55 PPD AHAM capacity, coverage up to 1,300 sq. ft., Energy Star certification and app-based remote control.
That mix suits a storage basement or a second home. You can check the room without walking downstairs each time.
You can monitor humidity and adjust settings through the free Wi-Fi app.
That is useful for a vacation property, storage basement or lower level that sits away from the main living area.
Set a target before you leave and check it from elsewhere. It also helps if you want to change the setting after a storm.
The 19.2 x 12.2 x 13.3 in dimensions and 41.7 lb weight match the compact shape of the other 120-pint AlorAir models.
That familiarity helps if you are comparing it with the HD55S. The main change is control style, not footprint.
Continuous drainage with an included hose avoids frequent tank emptying.
You still need a safe outlet for the hose. Check the route during the first week to be sure water leaves as expected.
Automatic defrost supports operation in low temperatures.
That helps in a cool basement that stays damp in winter. Moisture removal can slow while frost clears, then resume.
The MERV-1 filter helps protect internal parts.
Keep the filter clean and the air path open. Remote control does not remove the need for basic care.
Wi-Fi adds value only if remote access matters to you.
The HD55S may be the simpler choice for a nearby basement. If you walk past the unit each day, app control may add little.
ALORAIR 70 Pints Crawlspace Dehumidifier for Commercial: Best for simple gravity drainage
- 35 PPD AHAM capacity
- Up to 1,000 sq. ft.
- 6.5 ft drain hose
- Manual humidity controls
The Sentinel HS35 is a straightforward choice when a floor drain sits below the unit and you want simple controls.
Pros
- Compact dimensions
- Gravity drainage
- Automatic restart
Cons
- No built-in pump
- Lower capacity than the 120-pint models
The Sentinel HS35 is a straightforward choice for a basement with a nearby floor drain.
It removes 35 PPD at AHAM conditions, reaches 70 pints at saturation and covers up to 1,000 sq. ft.
That fits a smaller basement with steady damp. It suits control rather than a full restoration dry-out.
Its 6.5 ft drain hose supports continuous gravity drainage.
With no built-in pump, the hose must run downhill to the drain. Keep it short, kink-free and steadily sloped.
The 15.35 x 11.2 x 11.4 in body is compact for a furnace or shelf corner. Measure the doorway before you buy.
At 37.8 lb, plan the carry and get help on steep steps.
A handle helps with positioning. Leave space to reach it again for cleaning.
Manual humidity controls keep operation simple. Set the target and let the unit run.
Automatic defrost supports cooler conditions, with the fan running while frost clears.
Memory restart restores operation after a power interruption.
AlorAir describes operation below 50 dB. Keep it away from walls and stored items so air can move.
It suits a simple downhill drain. It is less suited when the drain sits higher than the unit.
ALORAIR 180 PPD Commercial Dehumidifier with Pump: Best for restoration-scale drying
- 85 PPD AHAM capacity
- Up to 2,300 sq. ft.
- Built-in pump
- 210 CFM airflow
The Storm LGR Extreme is intended for very large spaces and demanding drying work, with pump drainage and high airflow.
Pros
- Highest AHAM capacity here
- Digital display
- Automatic restart
Cons
- 64.3 lb weight
- More capacity than most everyday basements need
The Storm LGR Extreme is intended for a very large basement or serious drying work.
Its 85 PPD AHAM capacity, 180-pint saturation figure and 2,300 sq. ft. coverage rating put it above the everyday basement models.
That scale suits open-plan basements, workshops and rooms with heavy moisture. It is more than most finished basements will need for routine control.
A built-in pump and 19.6 ft drain hose support flexible placement.
The pump's stated vertical lift is 14.7 ft, so measure the full route from the unit to the discharge point.
Keep the hose as straight as you can. A shorter route gives the pump less work.
The 210 CFM airflow and digital display suit a unit used for restoration or large damp areas.
The display helps you check conditions at a glance. The airflow helps move damp air through the unit at a steady rate.
At 22.8 x 13.7 x 17.3 in and 64.3 lb, it needs more space and careful handling.
Plan the route downstairs before it arrives. Get help if the stairs are narrow or the basement door is tight.
Automatic defrost, automatic moisture removal and memory starting reduce routine supervision.
Those features help on a job that runs for days. The unit can resume its setting after a power cut.
For a normal finished basement, this capacity may be more than you need.
Oversizing can mean a larger unit to store and move. A smaller model may fit the room and the drain route better.
For a large space with heavy moisture, its extra headroom can be useful.
That headroom can help after a leak or a long wet spell. It suits shoppers who need strong drying over a wide area.
AlorAir 180 PPD LGR Commercial Dehumidifier: Best for heavy-duty job sites
- 85 PPD AHAM capacity
- Up to 2,300 sq. ft.
- Built-in pump
- 678.5 W power draw
The Storm SLGR 850X offers large commercial capacity, a built-in pump and a readable LCD display for demanding drying work.
Pros
- Large coverage rating
- Built-in pump
- Wheels and retractable handle
Cons
- Commercial size may be excessive for routine humidity control
- Highest stated wattage in this group
The Storm SLGR 850X is a heavy-duty option for large basements, garages or job sites.
It removes 85 pints per day at AHAM conditions, reaches 180 pints at saturation and covers up to 2,300 sq. ft.
That suits a wide open space or a job site needing steady drying.
Its built-in pump and continuous-draining design help where gravity drainage is not practical.
You can send water to a higher or farther outlet. Keep the route short and check the end drains freely.
The 21 x 11.6 x 17.6 in body is narrower than the Storm LGR Extreme.
That may fit a tight corner better. Measure the spot and leave room around the intake and outlet.
Its 678.5 W power draw is high in this group. Consider where it will run and how often it will cycle.
A large LCD display shows temperature and humidity at the inlet and outlet. That helps you check progress from a short distance.
Wheels and a retractable handle support movement between work areas.
Automatic defrost can pause moisture removal while frost clears, then resume.
This model suits restoration-scale drying. Choose it when both space and moisture load are large.
How should you choose an AlorAir dehumidifier for a basement?
Choose capacity by the basement's area and moisture level, then choose drainage by the location of the nearest outlet. A model that is powerful enough but cannot drain safely will be harder to use every day.
For spaces near 1,000 sq. ft., the Sentinel HS35 and HD35P are the smaller options. The HD35P is the better match when you need a pump, while the HS35 suits a simple downhill hose route.
The HD55, HD55S and Wi-Fi 120-pint model cover about 1,200 to 1,300 sq. ft. The HD55S adds Energy Star certification, and the Wi-Fi model adds remote monitoring.
For large basements, the Storm 80X reaches 2,100 sq. ft. The 180-pint models reach 2,300 sq. ft. and are better suited to heavy moisture or restoration work than ordinary humidity control.

What drainage setup does a basement dehumidifier need?
The best drainage setup depends on whether water can flow downhill.
Gravity-drain models need a steady downward route, while pump models can send water upward or farther.
Start by finding the nearest safe outlet. A floor drain, condensate line or suitable sink can work if the route is clear.
Place the unit on a stable surface with room around the intake, outlet and service areas.
Keep it level and away from stored boxes. Air needs a clear path in and out.
Keep the hose from kinking and confirm its end cannot back up or sit in standing water.
A kink can stop water leaving the unit. A blocked end can send water back toward it.
Check the hose during the first few days. Watch for leaks at joints and pooling near the outlet.
The HD55, HD55S and HS35 suit a nearby downhill drain. Keep the slope gentle but steady.
The HD35P, Storm 80X and 180-pint models suit a higher or farther drain.
A pump gives more placement freedom. Still measure lift and hose length before setting the unit in place.
A hanging kit can help raise a compatible unit in a crawl-space-style installation.
Only use it when unit, attachment points and service access suit suspended placement.
Check joists and keep straps level so you can lower the unit safely.
Leave room to reach filter, controls and hose connection. A good setup lets the unit run without daily attention.
How do you run an AlorAir dehumidifier every day?
Set the target humidity, confirm continuous drainage and keep the filter path clear.
Check the hose and drain outlet during the first cycles to make sure water leaves as expected.
Place the unit where air can move freely. Keep it away from walls, boxes and curtains blocking the intake or outlet.
Automatic defrost pauses the compressor while the fan clears frost in cool spaces.
Moisture removal can slow during that cycle. Give the unit time to finish before judging performance.
Clean or replace the filter under the care instructions and the dust level.
Construction dust, storage debris or a dirt floor may need closer attention. A clogged filter can reduce airflow and slow drying.
Leave room to move the unit for service.
Larger models have wheels or handles, but weight still makes stairs and placement important.
Plan the route before it arrives. Get help if stairs are steep or the door is narrow.
Match the setting to the room. Storage, finished and utility areas may need different targets.
Use a hygrometer for a clear reading of whether the room holds steady.

If drainage is your main concern, our Best Pump Dehumidifier For Basement guide covers that use case.
Those guides can help plan budget and drain route and show other setups for the same daily tasks.
Which AlorAir basement dehumidifier should you buy?
Pick the Sentinel HD55 for a balanced basement setup with automatic drainage and 53 PPD AHAM capacity.
That pick suits many everyday basements up to 1,200 sq. ft. It needs a downhill drain route and a stable corner.
Choose the Storm 80X for a larger basement or any layout that needs a built-in pump.
Its 80 PPD AHAM capacity and 2,100 sq. ft. rating suit a bigger space. The pump helps when the drain is higher or farther away.
Pick the HD55S for Energy Star certification.
It offers 55 PPD at AHAM conditions and coverage up to 1,300 sq. ft. It still needs a downhill hose route.
Pick the HDi65S Wi-Fi for remote monitoring.
That model suits a basement you do not visit often. You can check humidity and change settings from the app.
Pick the HD35P for a smaller space with upward drainage.
Its pump can lift water up to 19.6 ft vertically. That suits a compact basement where a floor drain is hard to reach.
Choose the HS35 when a simple gravity drain is available.
Its manual controls and 6.5 ft drain hose suit a nearby outlet below the unit. It is a simple fit for a smaller basement.
The 180-pint models are specialist choices for very large spaces or restoration-scale drying.
They offer 85 PPD at AHAM conditions and coverage up to 2,300 sq. ft. They also need more floor space and careful handling.
Measure the room, plan the drain route and compare the AHAM capacity before deciding among these AlorAir dehumidifiers for basements.
That order helps you avoid a unit that is too small, too large or hard to drain.

Frequently asked questions
What is the best AlorAir dehumidifier for a basement?
The ALORAIR 113 Pints Crawlspace Dehumidifier for Commercial is the best fit for most basements in this group. It removes 53 pints per day at AHAM conditions, covers up to 1,200 sq. ft. and drains continuously without requiring you to empty an internal tank.
Choose a pump model when the drain point is higher than the unit.
Do AlorAir basement dehumidifiers need a drain?
Yes. These models are designed for continuous drainage, so plan a route to a floor drain, condensate line or other suitable outlet.
Pump models can move water upward, while gravity-drain models need the hose to slope down from the unit.
Check the hose path before setting the target humidity.
What does PPD mean on an AlorAir dehumidifier?
PPD means pints per day. AlorAir gives both saturation and AHAM figures for several models, and the AHAM number is the more useful comparison for typical room conditions.
For example, the HD55 is rated at 113 pints at saturation and 53 PPD at AHAM conditions.
Should a basement dehumidifier have a pump?
A pump helps when the drain point is above the dehumidifier or far from the installation area. The Sentinel HD35P, Storm 80X and Storm LGR Extreme include built-in pumps with stated hose or lift details.
If water can flow downhill to a nearby drain, gravity drainage may be simpler.
