8 Best Dehumidifiers Under $100 2025

Unleashing serious moisture-fighting power in a sleek package, the AMEIFU dehumidifier stands out as a top-tier choice for those demanding both performance and peace. With its dual-semiconductor condensation technology, this unit pulls up to 40 ounces of moisture per day—a standout in the sub-$100 category—while maintaining energy efficiency at just 24W per hour. The massive 135-ounce tank means fewer trips to empty it, making it a true workhorse for larger spaces up to 1,000 sq.ft, especially in damp basements or humid bathrooms where constant moisture is a battle. It tackles mold, musty odors, and window condensation with quiet authority.

In real-world testing, the AMEIFU impresses with near-silent sleep mode (20dB), making it ideal for bedrooms or nurseries where noise sensitivity is key. The 8 timer options (up to 72 hours) offer unmatched flexibility—perfect for scheduling dehumidification during peak humidity hours or while away on weekend trips. It handles 86°F and 80% RH conditions with stable output, though dehumidification slows slightly in colder environments below 60°F, a limitation of Peltier tech. While it won’t match compressor-based units in extreme damp, it balances capacity, runtime, and noise better than most in its class.

When compared to the Windangel or TABYIK models, the AMEIFU dominates in tank size and daily extraction, making it best for larger rooms or continuous use. It’s not the most compact, but the trade-off is clear: more power, more runtime, fewer interruptions. Perfect for homeowners needing a set-and-forget solution in living rooms, master bedrooms, or RVs, it outperforms smaller units without breaking the bank. Priced higher than budget picks, it delivers premium features like extended timers and auto-defrost, just shy of the KeepGlad’s smart display but with a bigger tank.

Whisper-quiet and sleekly designed, the TABYIK dehumidifier earns its title as the best for silent operation, delivering a serene experience perfect for light sleepers and office spaces. With a near-inaudible 28dB output in sleep mode, it disappears into the background while still pulling up to 16oz of moisture daily in 86°F and 80% RH conditions—solid for a compact Peltier unit. The transparent 35-ounce tank lets you monitor water levels at a glance, and the ergonomic handle makes emptying and relocating effortless, ideal for small bathrooms or closets where space is tight.

During testing, the three-mode system (Sleep, Normal, Performance) proved versatile—sleep mode barely registers, while performance mode ramps up fan speed to tackle sudden humidity spikes after showers or laundry days. It handles spaces up to 280 sq.ft effectively, though larger or poorly insulated rooms will see limited impact. The 7-color LED light adds ambiance without being distracting, and the auto shut-off at 700–800ml prevents overflow safely. One limitation: tank capacity requires daily emptying in high-humidity zones, which may frustrate users seeking hands-off operation.

Against the Windangel or SPACEKEY models, the TABYIK shines in noise control and portability, though it can’t match their tank sizes or daily extraction. It’s not built for basements or large bedrooms, but for a bedside table, dorm, or half-bath, it’s hard to beat. The ideal pick for those prioritizing quiet over capacity, it offers reliable performance where silence matters most. Compared to the AMEIFU, it’s less powerful but far more discreet, striking a balance between function and serenity.

Precision-engineered for tight spaces, the Windangel dehumidifier is a compact moisture warrior that brings serious functionality to closets, RVs, and tiny bathrooms. Despite its miniature footprint (5.46 x 5.46 x 8.91 inches), it extracts up to 11.8oz of water per day under standard conditions (86°F, 80% RH), thanks to its efficient Peltier system. The 300ml increase in tank capacity over TABYIK reduces emptying frequency, and the ultra-low 24W power draw makes it an energy-sipping solution perfect for 24/7 operation in small, enclosed areas plagued by mildew or foggy mirrors.

In real-world use, the three dehumidification modes adapt well—sleep mode is library-quiet, ideal for bedside use, while performance mode tackles post-shower humidity in under 30 minutes. The 4 timer settings (24/48/72H + continuous) offer smart scheduling, and the 10-color mood light with adjustable brightness doubles as a nightlight or ambient decor piece. However, the 215 sq.ft coverage limit means it struggles in open-concept spaces or drafty rooms. Also, no drain hose support limits continuous use, a drawback if you’re seeking true maintenance-free operation.

Stacked against the TABYIK, the Windangel offers more color options and slightly higher extraction, but at the cost of less intuitive controls and no transparent tank. It’s not for large rooms, but for dorms, shoe closets, or travel use, it’s a standout. The perfect fit for renters or students needing a portable, low-maintenance fix for localized dampness. While the AMEIFU dominates in power, the Windangel wins in portability and targeted performance, offering smart features in a palm-sized package.

Engineered for spacious comfort, the SPACEKEY 95-ounce dehumidifier is a high-performance contender tailored for large rooms and damp basements up to 1,000 sq.ft. Its dual semiconductor tech pulls 40oz of moisture daily, matching pricier models, while the 20dB sleep mode ranks among the quietest in class—ideal for bedrooms where silence is non-negotiable. The sleek, handle-equipped design makes it easy to move between rooms, and the 7-color LED starry light panel adds a decorative flair, transforming a utilitarian device into a mood-setting accent.

In performance trials, it maintained consistent dehumidification in living rooms and basements, reducing sticky air and wall dampness within hours. The compact footprint (13.78”H) fits neatly in corners, and the auto shut-off with flashing red light prevents spills when the tank fills. However, without a drain hose option, it’s not ideal for unattended long-term use in flood-prone areas. It performs best above 59°F, as cold rooms slow condensation, a known Peltier limitation. Still, for closed, medium-to-large spaces, it delivers reliable, quiet operation.

Compared to the AMEIFU, it has a smaller tank (95oz vs. 135oz) but a more attractive design and comparable noise levels. Against the KeepGlad model, it lacks a digital display and washable filter but costs less and runs quieter. It’s the best pick for those wanting large-room coverage with near-silent operation and stylish design. While the AMEIFU lasts longer between empties, this unit balances aesthetics, performance, and affordability, making it a smart upgrade from mini dehumidifiers.

A seamless blend of convenience and continuous operation, this dehumidifier earns its title as the best with drain hose support, eliminating the daily chore of emptying tanks. With a 2.5L (85oz) capacity and included drain hose, it’s built for set-and-forget use in basements, RVs, or laundry rooms where moisture lingers. Its dual-core semiconductor system pulls up to 40oz/day, and the three-speed timer (8/16/24H) lets you customize runtime without constant monitoring. At under 30dB in sleep mode, it’s also ideal for noise-sensitive areas like nurseries or home offices.

Testing revealed excellent humidity control in 800 sq.ft spaces, especially when paired with closed doors and proper airflow. The 7-color LED light cycles smoothly, adding a calming glow, and the compact 5.2 lb design with handle makes portability easy. However, fan speed adjustment doesn’t drastically boost drying speed, and the plastic build feels less durable than metal-housed units. It performs well above 59°F but, like all Peltier models, struggles in unheated spaces during winter.

Against the KeepGlad, it matches drain hose utility but lacks a filter, making it less ideal for allergy sufferers. Compared to the AMEIFU, it offers automation but smaller tank size. It’s the top pick for those wanting hassle-free, continuous dehumidification without spending over $70. For RV owners or basement dwellers, it delivers reliability and flexibility, outperforming units that force daily maintenance.

Striking the sweet spot between cost and capability, this dehumidifier claims the best value under $60 crown with its 95-ounce tank and 1,000 sq.ft coverage—a rare combo in this range. It uses semiconductor cooling to quietly extract moisture, with sleep mode fading to a whisper and lights turning off for uninterrupted rest. The 7-color ambient lighting lets you customize the vibe, from romantic red to calming blue, making it as much a mood enhancer as a moisture fighter. It’s a no-frills workhorse with style, perfect for budget-conscious buyers who don’t want to sacrifice coverage.

In real use, it handles living rooms and master bedrooms with ease, reducing clamminess within hours. The auto shut-off at full tank prevents spills, and the sleek, modern design blends into any decor—a plus for visible spaces. However, no timer, no drain hose, and no filter mean you’ll be emptying it manually every 1–2 days in high humidity. It performs best in enclosed, temperature-stable rooms, and like all Peltier units, efficiency drops in cold conditions.

Compared to the $35 Windangel, it offers far greater coverage and capacity for just $25 more. Against the $69.99 KeepGlad, it lacks advanced features but wins on simplicity and price. It’s the ideal upgrade from mini dehumidifiers for those needing large-room performance without complexity. While the AMEIFU lasts longer between empties, this model delivers the most bang for under $60, making it the smartest budget buy for big spaces.
