How this dehumidifier scores for different use cases
The 45 pint/day capacity and 4500 sq ft coverage handle most basements well. It has continuous drain and auto-defrost, but lacks a built-in pump for flexible drainage placement.
The 4500 sq ft coverage and 45 pint/day capacity suit large areas. However, the lack of a pump drain, Wi-Fi control, and smart features limits its set-and-forget potential.
The 40 dB noise level is reasonable but not ultra-quiet. It lacks sleep mode, night light, and remote control, which are important for bedroom use without getting out of bed.
At 24.4 lbs with no wheels or handle, this unit is not designed for small spaces. The 45-pint capacity is overkill for closets or RVs, and portability is limited.
The 45-pint capacity falls short of commercial needs. No pump drain, no heavy-duty construction features, and the small 0.58-gallon tank make it unsuitable for industrial applications.
This unit has no Wi-Fi, no app control, and no voice assistant support. It offers only a basic touch panel with no smart home integration whatsoever.
Our Verdict
The ASAHWo PD22SA-1 pulls 45 pints of moisture per day. It covers up to 4500 square feet. That puts it squarely in the mid-to-large capacity range.
At $159.99, you pay about $3.56 per pint of daily capacity. Most 45-pint units cost $200 or more. Your wallet gets a real break here.
The continuous drain hose lets you skip daily tank emptying. The auto-defrost keeps coils clear in cool basements. These two features make it a solid basement pick.
The 40 dB noise level sits in the average range. You will hear it running in a quiet room. A missing sleep mode hurts its bedroom appeal.
No wheels or handle means you carry all 24.4 pounds by hand. Moving it between rooms takes real effort. Plan to keep it in one spot.
Smart home fans should look elsewhere. This unit has zero Wi-Fi or app features. You control everything from the touch panel on top.
The 0.58-gallon tank fills fast without the drain hose connected. Use the included hose for hands-free operation. That small tank is its biggest daily hassle otherwise.
What We Like
- Removes 45 pints of moisture per day, enough for spaces up to 4500 square feet.
- Priced at $159.99, well below the average for 45-pint dehumidifiers.
- Includes continuous drain hose so you never empty the tank by hand.
- Auto-defrost keeps it running in cold basements down to lower temperatures.
- Three-color humidity indicator lights show room humidity at a quick glance.
What Could Be Better
- No built-in pump for draining water upward to sinks or windows.
- No wheels or carry handle, making it hard to move at 24.4 pounds.
- No Wi-Fi, app control, or voice assistant support for smart home use.
- No sleep mode for quiet overnight operation in bedrooms.
- The water tank holds only 0.58 gallons, much smaller than the 1.2-gallon average.

How big of a room can this dehumidifier handle?
It covers up to 4500 square feet. This works well for large basements, open living areas, or multiple connected rooms.
Do I have to empty the water tank by hand?
No. It comes with a 3.3-foot drain hose for continuous drainage. You can also use the 0.58-gallon tank and empty it yourself, but the tank is small and fills quickly.
How loud is this dehumidifier?
It runs at 40 dB or less. That is about the volume of a quiet library. You will notice it in a silent room, but it should not disrupt normal activities.
Can I control this dehumidifier with my phone or Alexa?
No. This model has no Wi-Fi, no app, and no voice assistant support. You control it only through the touch panel on the unit.
