Why this dehumidifier is interesting

Siguro Orca P300W is among the best-selling dehumidifiers on Alza – it has over 2000 units sold and a rating of 4.7 out of 5. Compared to cheaper models, it offers a higher dehumidification capacity of 20 l/day, WiFi control via the TUYA app, and air ionization. It is suitable for rooms up to 80 m², which covers even a larger apartment or basement.

Practical advantage: the device can be connected directly to a drain using a hose (1 m included in the package). This means you don’t have to constantly empty the tank, and the dehumidifier can run continuously – for example, when you are on vacation or dehumidifying after a renovation.

Key parameters in practice

The condensate tank has a volume of approx. 5.5–6.5 l (depending on the series) with a practical handle and a water level indicator. When full, the dehumidifier automatically switches off. The power consumption is 330 W, and the manufacturer states the noise level is below 45 dB – in practice, users confirm that operation is tolerable at a lower setting, but noisier at a higher setting.

Three operating modes are available: automatic (maintains set humidity 30–80%), continuous dehumidification, and laundry drying mode. The latter is practical – laundry dries up to 2 times faster according to users. Also included are a night mode, a timer (1–24 hours), and a child lock.

Practical aspects: WiFi, control, maintenance

Control is via the touch panel on the device body or remotely via the TUYA app (Android and iOS). In the app, you can see the current humidity and temperature, set a time schedule, and turn the dehumidifier on/off from anywhere. A colored LED indicator on the front shows the humidity level at a glance: blue (below 45%), green (45–65%), red (above 65%).

The device weighs 14 kg, but has transport wheels and handles, making it comfortable to move. The filtration system combines a nylon washable filter and an activated carbon filter. The Anti-Freeze function protects the dehumidifier from freezing – so you can use it even in unheated areas. The warranty is 36 months.

What users say

On Alza, the Siguro Orca P300W has a rating of 4.7 out of 5 (171 ratings) and 94% of customers recommend it. The complaint rate is 1.83%, which is a low value. Users most often praise the dehumidification performance – several reviewers state that the device fills the 5–6l tank in 8–12 hours at higher humidity. One user in a basement reduced humidity from 65% to 50% in 40 minutes.

Also positively rated are the option to connect to a drain, the large tank with a handle, and the fact that WiFi control works remotely – so dehumidification can be started, for example, from vacation. Several users appreciate that the device helped solve foggy windows and mold on walls.

Criticism focuses on several points: WiFi pairing is more complicated than it should be – there is an error in the manual, and correctly, you need to hold the TIMER button (not the power button) until the WiFi indicator flashes. Some users report that the integrated hygrometer is not entirely accurate and differs from external meters. When emptying the tank, water leaks a bit outside the pouring opening – it is recommended to empty it into a bathtub. And at a higher setting, the device is noisier – not ideal for sleeping in the same room.

When it doesn’t make sense

If you need a quiet dehumidifier for a bedroom where you will be sleeping, be aware that compressor devices are generally noisier. Night mode reduces noise, but it is still audible. Desiccant dehumidifiers are more suitable for sleeping in the same room, as they are quieter (but more expensive and less powerful).

Also, if you only have a 5GHz WiFi network at home, you will need to set up a 2.4GHz band as well – the device only supports 2.4 GHz. And if you expect full control in the app (consumption, tank status, all functions), you will be disappointed – the TUYA app only offers basic control.

Verdict: who it’s worth it for

The Siguro Orca P300W for 4,193 Kč (with code ALZADNY30) is a solid choice for those dealing with increased humidity in an apartment, basement, or garage. You get a powerful dehumidifier with a capacity of 20 l/day, the option to connect to a drain, WiFi control, and a 3-year warranty. With a complaint rate under 2% and over 2000 units sold, it is a proven choice – just be aware that WiFi pairing may require a bit of patience.
