What to know first
- It’s a 70-pint class dehumidifier, which is the top end of typical consumer units before you step into pricier commercial gear.
- Built-in pump is the headline feature. It can move water through a hose instead of relying on gravity drainage.
- Bucket capacity is 14.4 pints, so bucket-only use can mean frequent emptying in very humid stretches.
- It’s a large, wheeled unit (45 lb), so plan for it to live on one floor and roll short distances.
- A hose may not be included, so confirm what’s in the box before you buy if you’re planning continuous drainage.
What the Honeywell DH70PW is
The Honeywell DH70PW is a full-size dehumidifier in the 70-pint class. That “70” rating is a standardized way to compare units under warm, humid conditions, not a promise that every basement will see that exact output. In real homes, cooler temperatures and lower humidity usually mean less water pulled per day.
This model is built for the places that actually need a dehumidifier: basements, large rec rooms, and other damp areas where you want to keep humidity under control for comfort and to reduce that clammy, musty feeling. It can collect water in its internal bucket or send it out through a hose for continuous drainage.
The key differentiator is the built-in pump. Instead of needing a hose that runs downhill the whole way to a floor drain, a pump-equipped unit can push water to a sink or another drain point that’s not conveniently below the machine.
Why it stands out
The built-in vertical pump is the reason to pay attention to the Honeywell DH70PW. Continuous drainage is what turns a dehumidifier from a chore into an appliance you can leave running during long humid stretches. With a gravity drain, you are limited by where the machine sits and whether you can maintain a constant downhill slope. A pump gives you more placement options.
It’s also a true 70-pint class unit, which is the largest common size in mainstream consumer dehumidifiers. That matters because higher-capacity units are designed to handle heavier moisture loads and larger, more humid spaces. Even if you’re using it in a smaller area today, a 70-pint unit gives you more headroom for tougher conditions later.
Under warm, humid conditions, this model’s moisture collection lands in the same general performance band you’d expect from a 70-pint machine. In a four-hour run under controlled conditions, it collected 13.1 pints of water, which translates to an estimated 78.6 pints over 24 hours if you extend that rate. In a real basement, expect output to vary with temperature, humidity, and airflow.
What it is like to own
In daily use, you’ll interact with the Honeywell DH70PW in one of two ways: emptying the bucket or setting up a drain hose. If you use the bucket, the 14.4-pint capacity is workable, but it can fill quickly when humidity is high. That’s the reality of any high-capacity dehumidifier: when it’s doing its job well, it’s making water you have to deal with.
If you set it up for continuous drainage, the built-in pump is what makes the setup more forgiving. You can route a hose to a sink or other drain point without needing the hose to run downhill the entire way. That’s often the difference between “I can actually place this where it works best” and “I’m stuck parking it next to the only floor drain.”
This is a big appliance. At 45 pounds, it’s not something you’ll want to carry up and down stairs regularly. It does have wheels, which is what you want for rolling it around a basement or across a hard floor when you need to reposition it.
What to know before you buy
Don’t buy any dehumidifier based on “covers X square feet” alone. Layout, airflow, temperature, and how wet the space is matter more than floor area. A 70-pint unit is generally meant for heavier-duty jobs, but your results will still depend on the room conditions.
Confirm the drainage details before checkout. This model supports continuous pumping, but a hose may not be included. If you’re counting on continuous drainage, you don’t want to discover you need an extra part after the box arrives.
Also keep expectations realistic about the 70-pint rating. That number is measured under standardized warm, humid conditions. Cooler basements can reduce water removal and can also trigger defrost behavior in many dehumidifiers, which means the unit periodically pauses dehumidifying to deal with frost on the coils.
The specs that matter
A 70-pint unit is built for heavier humidity and larger damp spaces. In cooler or less humid rooms, it’ll pull less than the rating, but the rating is still useful for comparing models.
A pump lets the unit push water through a hose to a sink or other drain point, instead of requiring a perfectly downhill gravity drain. That’s what enables unattended draining in more homes.
If you’re not using a hose, bucket size determines how often you’ll be emptying it. In very humid conditions, a mid-size bucket can fill fast.
If you plan to drain continuously, you may need to buy a compatible hose separately. It’s a small detail that can delay setup.
This is a roll-it-around appliance, not a carry-it-around appliance. Wheels help on one level, but stairs are a different story.
It shows the DH70PW can move a lot of moisture when conditions are warm and humid. Your home’s temperature and humidity will change the real-world number.
Who this product fits
You have a basement with no floor drain where you want the dehumidifier
The Honeywell DH70PW’s built-in pump gives you a practical way to run a hose to a sink or other drain point, instead of parking the unit in the one spot where gravity drainage works.
You’re dealing with heavy summer humidity and want fewer bucket runs
As a 70-pint class unit, it’s designed to pull a lot of water in humid conditions. Pairing that capacity with continuous pumping is the easiest path to not emptying a bucket every day.
You want one dehumidifier that can handle a bigger space later
A 70-pint unit gives you more headroom than a 30- or 50-pint model. If you start in a bathroom or small room and later move it to a basement, you’re less likely to feel underpowered.

Honeywell DH70PW FAQ
Does the Honeywell DH70PW have a built-in pump?
Yes. The DH70PW includes a built-in vertical pump, which is meant to support continuous drainage through a hose without relying on a constant downhill run.
Does the Honeywell DH70PW come with a hose?
Not necessarily. The published specifications indicate no hose included for continuous pumping, so it’s smart to confirm what’s in the box from the specific seller listing before you buy.
How big is the Honeywell DH70PW water bucket?
It has a 14.4-pint bucket. If you use bucket collection instead of a hose, that capacity affects how often you’ll be emptying it during humid weather.
Is a 70-pint dehumidifier too much for a small room?
A 70-pint unit can still be used in smaller spaces, but it’s typically chosen for heavier humidity or larger damp areas. The main reason to go this big in a smaller room is future flexibility or tougher moisture conditions.
Will the Honeywell DH70PW actually remove 70 pints per day in my basement?
Not always. The 70-pint figure is a standardized rating under warm, humid conditions. Cooler basements or less humid rooms usually reduce real-world water removal, so use the rating as a comparison tool rather than a guarantee.
Should you buy the Honeywell DH70PW?
Buy the Honeywell DH70PW if you want a 70-pint class dehumidifier and the built-in pump solves a real placement problem in your home. That one feature can be the difference between continuous, unattended drainage and a machine you end up ignoring because emptying the bucket is a hassle.
If you’re starting from zero and just want the most straightforward, well-supported choice, start with one of our primary alternatives instead. The DH70PW makes the most sense when you already know you want this specific Honeywell model and you’re willing to double-check the drainage setup details (especially hose inclusion) before you commit.
