The Midea MAD35S1QWT is a 35-pint dehumidifier with a collapsible design, a configuration you can see here. It's all but identical to the Midea MAD35PS1QGR but does without the latter's drain pump. Otherwise, it's identically equipped, with Wi-Fi connectivity and support for voice commands made through Amazon Alexa and Google Assistant.

Our Verdict

7.6 Basement

The Midea MAD35S1QWT is a good choice for basement use. While it lacks a drain pump, it can be configured to drain continuously, either directly from its drain hole or via the included hose. Its dehumidification capacity is also enough for medium-sized dens. It's also very efficient and won't significantly impact your energy bill.

Pros
  • Space-saving design when configured for continuous drainage.
  • Great energy efficiency.
  • Decent dehumidification capacity.
Cons
  • No drain pump.
6.7 Bathroom

The Midea MAD35S1QWT is okay for use in bathrooms. It takes up quite a bit of space in its fully extended configuration. However, you can remove the dehumidifier unit from the water bucket and hook it up to its included hose to have it drain continuously. Unfortunately, you'll have to place it in an elevated position if you need to have it drain into a bathtub or sink since there's no built-in pump.

Pros
  • Space-saving design when configured for continuous drainage.
  • Great energy efficiency.
  • Decent dehumidification capacity.
Cons
  • Bulky fully-extended configuration.
  • No drain pump.
  • Produces a moderate amount of heat.
7.4 Large Room

The Midea MAD35S1QWT is decent for large rooms. Its dehumidification performance is satisfactory overall, but it'll struggle more than a higher-capacity unit when pulling the moisture from larger rooms. It's not especially quiet either and can be distracting while watching TV or listening to music, but it's also far from the noisiest machine on the market. On the upside, it's quite energy-efficient and has a large water bucket you won't need to empty often.

Pros
  • Great energy efficiency.
Cons
  • Fairly noisy.
7.0 Bedroom

The Midea MAD35S1QWT is a satisfactory option for use in bedrooms. It's pretty big and bulky when fully deployed, making it a little challenging to fit in smaller rooms. Thankfully, it doesn't emit quite as much heat as some alternatives. It's also strictly middle-of-the-road as far as operating noise is concerned. If you're a deep sleeper, it won't be too much of a distraction while running overnight, but more sensitive sleepers might be annoyed.

Pros
  • Great energy efficiency.
  • Decent dehumidification capacity.
Cons
  • Bulky fully-extended configuration.
  • Fairly noisy.
  • Produces a moderate amount of heat.
7.2 Capacity

The Midea MAD35S1QWT provides satisfactory dehumidification capacity. It's best suited to dehumidifying medium-sized rooms, but it might struggle in especially large, open-concept spaces.

Pros
  • Decent dehumidification capacity.
Cons
6.6 Noise

The Midea MAD35S1QWT is fairly quiet. It might be distracting if you leave it on while watching TV nearby, but it isn't loud enough to overwhelm nearby conversation.

Pros
Cons
  • Fairly noisy.
7.0 Temperature Stability

The Midea MAD35S1QWT does a decent job of maintaining a stable temperature. If you leave it running for a few hours in a small room, it might feel a bit stuffy, but you won't notice its impact too much when you place it in a large room.

Pros
Cons
  • Produces a moderate amount of heat.
  • 7.6 Basement
  • 6.7 Bathroom
  • 7.4 Large Room
  • 7.0 Bedroom

Differences Between Sizes And Variants

The Midea MAD35PS1QGR is only available in a 'White' colorway. You can see the label of the unit we tested here.

Let us know in the comments if you come across another variant of this dehumidifier.

Compared To Other Dehumidifiers

The Midea MAD35S1QWT is a 35-pint dehumidifier with Wi-Fi connectivity. It offers decent overall dehumidification performance and has a large water tank for a unit with this capacity. However, its biggest advantage over most other conventional 35-pint dehumidifiers is its collapsible design, which saves on space when the machine is not in use or when it's configured to drain continuously. That said, unlike the similar Midea MAD35PS1QGR, it lacks a drain pump, and the latter would be the better option for use in basements or bathrooms, where you'd need to have the unit drain into a sink, bathtub, or any other elevated container.

This dehumidifier has decent airflow performance, similar to the closely related Midea MAD35PS1QGR. The MAD35S1QWT's max fan speed setting is sufficient to promote air movement in medium-sized spaces, but it'll have a harder time in big, open-concept spaces. Its slow fan speed setting produces a fairly low minimum airflow, which can help keep the device's evaporator coils cool in cooler humid rooms and creates less disturbance when you place the device nearby.
