A portable dehumidifier does its job, but it also takes up floor space, hums in the middle of the room and needs its bucket emptied. That's why so many people search for a **wall mounted dehumidifier** — something that sits out of the way and drains on its own. Whether you call it an in-wall dehumidifier, a wall-mount unit or a ceiling-mounted dehumidifier, the goal is the same: permanent, hands-off humidity control.

Here's what to know up front. In the U.S., true hang-on-the-wall residential dehumidifiers are uncommon. The options that actually exist fall into a few groups: **in-wall units** recessed into a stud cavity, **ducted dehumidifiers** hidden in a closet, attic or basement that deliver dry air through grilles, and **suspended or platform-mounted units** in crawl spaces and commercial spaces. We've picked the best of each and been careful to stick to models we're confident are real and available.

All of these drain continuously through a condensate line, and most are best installed by an HVAC contractor.

## Our top picks

- **Best in-wall dehumidifier:** Santa Fe UltraMD33 — [check price on Amazon](https://www.amazon.com/dp/B0DS2VPWL3?tag=sktiger-20&linkCode=ll1)
- **Best whole-house (hidden) install:** Aprilaire E100 — [check price on Amazon](https://www.amazon.com/dp/B0DG3RJ1W5?tag=sktiger-20&linkCode=ll1)
- **Best HVAC-integrated:** Honeywell DR90A3000 — [check price on Amazon](https://www.amazon.com/s?k=Honeywell%20DR90A3000%20Whole-House%20Dehumidifier&tag=sktiger-20)
- **Best for crawl spaces and tight spots:** Santa Fe Compact70 — [check price on Amazon](https://www.amazon.com/dp/B07HCLL7FY?tag=sktiger-20&linkCode=ll1)

If you want a dehumidifier that literally lives inside your wall, the **Santa Fe UltraMD33** is the one to get: it recesses into an interior wall so only a grille shows, and it drains through a permanent line.

## 1. Santa Fe UltraMD33 In-Wall Dehumidifier — Best in-wall dehumidifier

[Check price on Amazon](https://www.amazon.com/dp/B0DS2VPWL3?tag=sktiger-20&linkCode=ll1)

**Pros**

- Recessed into the wall — no floor space used
- Continuous condensate drainage, no bucket
- Built by an established whole-home dehumidifier maker
- Suited to condos, apartments and small homes

**Cons**

- Requires cutting into a wall and running a drain
- Professional installation strongly recommended
- Smaller capacity than a ducted whole-house unit

**Why we picked it:** This is the closest thing to a true in-wall dehumidifier most U.S. homeowners can buy. It's designed to fit inside an interior wall cavity, pull air through a grille, and send condensate down a drain line, so the room gets steady humidity control with nothing sitting on the floor.

**Performance:** Santa Fe is the residential brand of Therma-Stor, a long-standing maker of whole-home and crawl-space dehumidifiers, and the UltraMD33 is its compact in-wall model. It's sized for condos, apartments and smaller homes rather than a sprawling basement. Because it's built in, the install matters as much as the unit: the wall cavity, power and condensate drain all need planning, which is why most owners have an HVAC contractor do it. See the rest of the brand's lineup in our [best Santa Fe dehumidifier](https://www.enthusiastreview.com/best/best-santa-fe-dehumidifier/) guide.

**Worth knowing:** Confirm your wall depth, stud spacing and drain route against Santa Fe's installation manual before buying.

| Spec | Value |
| --- | --- |
| Type | In-wall, recessed |
| Capacity | About 33 pints/day class |
| Drainage | Continuous condensate line |
| Install | Professional recommended |
| Best for | Condos, apartments, small homes |

## 2. Aprilaire E100 Whole-House Dehumidifier — Best whole-house (hidden) install

[Check price on Amazon](https://www.amazon.com/dp/B0DG3RJ1W5?tag=sktiger-20&linkCode=ll1)

**Pros**

- Dries the whole home through ducts
- Unit hides in a basement, attic or mechanical room
- ENERGY STAR Most Efficient recognition
- Can be ducted or run freestanding

**Cons**

- Professional ducting and drain work
- A big investment versus a portable

**Why we picked it:** If what you really want is no dehumidifier in sight, a ducted whole-house unit is the best answer. The E100 tucks away in a utility space and delivers dry air through ducts and wall or ceiling grilles, with condensate going straight to a drain.

**Performance:** Aprilaire rates it at up to 100 pints a day and coverage up to about 5,500 square feet, and it has earned ENERGY STAR Most Efficient recognition. It can tie into existing HVAC ductwork or run with its own ducts. Owners consistently say the best thing about it is that they never think about it.

| Spec | Value |
| --- | --- |
| Capacity | Up to 100 pints/day |
| Coverage | Up to about 5,500 sq ft |
| Install | Ducted or freestanding |
| Drainage | Continuous condensate line |
| Efficiency | ENERGY STAR Most Efficient |
| Warranty | 5 years |

## 3. Honeywell DR90A3000 Whole-House Dehumidifier — Best HVAC-integrated

[Check price on Amazon](https://www.amazon.com/s?k=Honeywell%20DR90A3000%20Whole-House%20Dehumidifier&tag=sktiger-20)

**Pros**

- Designed to connect to central HVAC ductwork
- 90-pint capacity for larger homes
- Drains continuously
- Out of sight in a mechanical space

**Cons**

- Needs a contractor familiar with your HVAC system
- Less flexible as a standalone than some rivals

**Why we picked it:** For homes with forced-air HVAC, this Honeywell is built to become part of the system, so the dry air reaches every room through the vents you already have. Nothing sits on a floor or hangs on a wall in your living space.

**Performance:** It's rated at 90 pints per day and is typically installed beside the furnace or air handler, with its own dehumidistat control. HVAC contractors are generally familiar with Honeywell's residential equipment, which can make finding an installer easier. Like any ducted unit, it needs a proper condensate drain with a trap. Compare it with other brand picks in our [best Honeywell dehumidifier](https://www.enthusiastreview.com/best/best-honeywell-dehumidifier/) guide.

| Spec | Value |
| --- | --- |
| Capacity | 90 pints/day |
| Type | Ducted whole-house |
| Install | Connects to HVAC ductwork |
| Drainage | Continuous condensate line |
| Best for | Homes with forced-air HVAC |

## 4. Santa Fe Compact70 Dehumidifier — Best for crawl spaces and tight spots

[Check price on Amazon](https://www.amazon.com/dp/B07HCLL7FY?tag=sktiger-20&linkCode=ll1)

**Pros**

- Small footprint for crawl spaces and closets
- 70-pint capacity
- ENERGY STAR Most Efficient (2024)
- Long warranty

**Cons**

- Not a wall-hanging unit — sits on a platform or floor
- Needs a drain route or condensate pump

**Why we picked it:** Many people searching for a wall- or ceiling-mounted dehumidifier for a basement or crawl space really need a compact, permanent unit that stays out of the way. The Compact70 packs a 70-pint rating into a body only about 12 inches square and 21 inches long.

**Performance:** Santa Fe rates it for up to about 2,200 square feet, and it earned ENERGY STAR Most Efficient recognition in 2024. Its small body fits between joists, in a mechanical closet or on a raised platform, and it can be ducted to move dry air where you need it. Owners like that it runs for years with little attention beyond filter cleaning. Our [crawl space dehumidifier installation](https://www.enthusiastreview.com/guides/crawl-space-dehumidifier-installation/) guide covers mounting and drainage.

| Spec | Value |
| --- | --- |
| Capacity | 70 pints/day |
| Coverage | Up to about 2,200 sq ft |
| Size | About 12 × 12 × 21 in. |
| Efficiency | ENERGY STAR Most Efficient (2024) |
| Warranty | 6 years |

## Types of wall, in-wall and ceiling-mounted dehumidifiers

| Type | How it mounts | Best for | Typical install |
| --- | --- | --- | --- |
| In-wall dehumidifier | Recessed into a wall cavity, grille on the face | Condos, apartments, small homes | Contractor |
| Ducted whole-house | Hidden in basement, attic or closet; dry air through wall or ceiling grilles | Whole homes | HVAC contractor |
| Suspended or platform-mounted | Hung from joists or set on a raised platform | Crawl spaces, basements, commercial spaces | DIY-capable or contractor |
| Commercial wall-mount | Bolted to a wall in pool rooms, greenhouses and similar spaces | Indoor pools, commercial rooms | Engineer-specified |
| Ductless mini-split (dry mode) | Indoor head on the wall | Rooms that also need cooling | HVAC contractor |

A wall-mounted ductless mini-split isn't a dedicated dehumidifier, but its dry mode removes moisture while it cools. If a room needs both, it can be the most practical wall-mounted option. Our [dehumidifier vs. air conditioner](https://www.enthusiastreview.com/guides/dehumidifier-vs-air-conditioner/) guide explains the trade-offs.

## How we pick wall-mounted dehumidifiers

We don't lab-test dehumidifiers. We compare manufacturer specifications, installation manuals, ENERGY STAR listings and capacity ratings, read owner reviews and installer feedback, and check CPSC recall records.

Because this category is full of vague listings, we added a stricter rule: we only recommend specific models we're confident exist and are sold for the purpose described. Where a mounting style is mostly custom or commercial, we describe the category instead of naming a product.

## What to look for in a wall-mounted dehumidifier

- **A continuous drain plan:** A mounted unit can't use a bucket. Plan a gravity line with a trap, or a condensate pump, before you buy.
- **Approved mounting:** Only suspend or wall-mount a unit in the orientations its installation manual allows. Attic installs typically need a secondary drain pan.
- **Power at the location:** Most units need a dedicated 115V outlet or hard-wired connection nearby. Damp locations usually call for GFCI protection.
- **Service access:** Filters need cleaning and coils occasionally need inspection. Leave room to reach the front panel.
- **Right-sized capacity:** A whole basement or home needs 70–100+ pints; a condo can get by with less. Our [dehumidifier size guide](https://www.enthusiastreview.com/guides/dehumidifier-size-guide/) helps.

## Wall-mounted dehumidifier options by room

### Wall-mounted dehumidifier for a basement

In a finished basement, an in-wall unit like the UltraMD33 keeps the floor clear, while a ducted whole-house unit or a compact 70-pint unit on a platform handles a large, unfinished basement. A heavy-duty wall shelf can also lift a portable unit so its drain hose has a downhill run, but make sure the shelf is rated well above the unit's weight. See our [best dehumidifier for basement](https://www.enthusiastreview.com/best/best-dehumidifier-for-basement/) guide for freestanding options.

### Wall-mounted dehumidifier for a bathroom

Wall-mounted bathroom dehumidifiers are uncommon in the U.S. The better fix is usually a quiet, humidity-sensing exhaust fan vented to the outdoors, which turns itself on when the room gets steamy. If a windowless bathroom still stays damp, a compact portable from our [best dehumidifier for bathroom](https://www.enthusiastreview.com/best/best-dehumidifier-for-bathroom/) guide can help.

### Ceiling-mounted dehumidifier

Ceiling-mounted dehumidifiers are usually ducted units installed in an attic or above a drop ceiling, delivering dry air through a ceiling grille, or commercial units suspended from the structure. Either way, plan the condensate drain and emergency overflow protection first; a leak above a ceiling is costly.

### Commercial wall-mounted dehumidifiers

Indoor pools, greenhouses and warehouses often use wall-mounted or suspended commercial units sized by an engineer for the specific moisture load. Start with our [best commercial dehumidifier](https://www.enthusiastreview.com/best/best-commercial-dehumidifier/) and [pool room](https://www.enthusiastreview.com/best/best-dehumidifier-for-pool-room/) guides.

## The bottom line

For a true in-wall dehumidifier, the **Santa Fe UltraMD33** is the standout. If you'd rather dry the whole house with nothing visible, choose a ducted unit: the **Aprilaire E100** for the most flexibility and efficiency, or the **Honeywell DR90A3000** for a system built around your existing HVAC. For a crawl space or tight mechanical space, the compact **Santa Fe Compact70** is the most practical permanent install. Whichever you choose, plan the drain line and power before you buy.

## Frequently asked questions

### Are there wall-mounted dehumidifiers?

Yes, but true wall-hanging residential units are uncommon in the U.S. The most common permanent options are in-wall units such as the Santa Fe UltraMD33, ducted whole-house dehumidifiers that deliver air through wall or ceiling grilles, and commercial wall-mount units for pools and similar spaces.

### What is an in-wall dehumidifier?

An in-wall dehumidifier is recessed into a wall cavity so only a grille shows on the room side. It draws in humid air, removes moisture and drains condensate through a permanent line, so there's no bucket and no floor space used.

### Is there a wall-mounted dehumidifier with a continuous drain?

Every mounted or built-in dehumidifier drains continuously — it has to, because there's no bucket. Plan a gravity drain with a trap or add a condensate pump to move water to a sink, floor drain or the outdoors.

### Can I hang a dehumidifier from the ceiling?

Only if its installation manual allows it. Some whole-house and crawl-space units can be suspended or platform-mounted; portable units generally should not be. Ceiling and attic installs should include overflow protection such as a secondary drain pan.

### Can I install an in-wall dehumidifier myself?

Experienced DIYers can, but most homeowners hire a contractor. The job involves cutting into a wall, providing power and running a condensate drain, and mistakes can lead to hidden leaks.

### What's the best wall-mounted dehumidifier for a bathroom?

In most U.S. homes, a humidity-sensing exhaust fan vented outdoors is the best permanent fix for a damp bathroom. Add a small portable dehumidifier only if the room stays humid after the fan has run.
