AlorAir Sentinel HD55 Crawl Space Dehumidifier (Blue) vs Midea Cube MAD20S1QWT 20-Pint Smart Dehumidifier
These are side-by-side facts taken from each product guide: published specifications, strengths and caveats as their sources state them. This page is not a test, a ranking or a verdict about which model is better.
AlorAir Sentinel HD55 Crawl Space Dehumidifier (Blue)
An unheated crawl space with a gravity drain below the unit
A metal-cased crawl-space dehumidifier with no water tank: condensate leaves by gravity hose only. AlorAir rates it 53 pints a day at 80°F and 60% humidity, or 113 at saturation, and it keeps working down to 33.8°F with auto defrost. R410A refrigerant, MERV-1 filter, 44 pounds.
Published specifications
- Maker spec sheet: 53 pints/day at 80°F 60% RH; 113 pints at saturation; up to 1,200 sq ft
- Maker spec sheet: functioning temperature 33.8-104°F, auto defrost, humidity 36-90%
- Maker spec sheet: 115 V 60 Hz, 4.0 A, 120 CFM (205 m3/h), 2.27 L/kWh
- Maker spec sheet: gravity draining only, no water tank, R410A refrigerant
- Maker spec sheet: 19.2 x 12.2 x 13.3 in, 44 lb; MERV-1 filter, adjustable feet
- Listing warranty field: 1 yr parts and labour; 3 yr refrigeration parts and labour; 5 yr refrigeration parts
Strengths
- Keeps running down to 33.8°F with auto defrost, where room dehumidifiers stop
- No bucket to empty: gravity drainage is the only mode, so it can be left alone
- AlorAir publishes a model-specific spec sheet with the test condition stated
Caveats
- The headline six-year warranty is layered; full parts-and-labour cover is one year
- Gravity-only drainage means it must sit above the drain, often on a hanging kit sold separately
- Amazon's spec table lists a 14.12-gallon tank; this unit has no tank at all

Midea Cube MAD20S1QWT 20-Pint Smart Dehumidifier
A small damp room where the unit can sit above the drain
A 20-pint Cube that nests inside its own bucket for storage. The listing states the rating is similar to 30 pints under the 2012 DOE test. It needs eight inches clear on every side and sixteen at the outlet, and it has no pump, so continuous draining means placing it above the drain.
Published specifications
- Maker page: MAD20S1QWT, 20 pints/day, 1,500 sq ft, built-in pump: No, 1-year warranty
- Listing: 20 pints is described as similar to 30 pints under the 2012 DOE test
- Manual: 8 in clear on all sides, 16 in at the air outlet, level floor, indoor only
- Manual: working environment 41°F to 95°F; auto defrost; 3-minute compressor delay
- Manual: bucket fill levels 1.5 / 2 / 2.75 / 3 gallons, up to about 29.5 lb of water
- Maker page: 13.5 D x 13.5 W x 13.39 H in, 33.07 lb
Strengths
- The listing names the older test standard, so the pint figure can be compared honestly
- Nests inside its own bucket to roughly half height for storage
- Bucketless mode, garden-hose adapter and a washable filter with a reset indicator
Caveats
- No pump: continuous draining only works with the unit above the sink or drain
- Sixteen inches of clearance at the air outlet can be hard to find in a small room
- A full bucket at the top setting is about three gallons, roughly thirty pounds to carry
