Would you like to improve the air quality in your home or do you have someone with allergies living with you? If so, there's nothing better than getting a high-quality air purifier. One such option is the Siguro AP-D400W Auk, which features an advanced filtration system, an ioniser, and a UV-C lamp. It effectively removes airborne dust, bacteria, microbes, mites, pollen, allergens, odours and other harmful substances commonly found in the air. Using this compact purifier can help prevent many respiratory problems, allergies, and other illnesses. It also offers intuitive controls, including the ability to connect to a mobile app, and an aroma box to pleasantly scent the room. The Siguro AP-D400W Auk Air Purifier is an excellent choice not only for homes but can also be used in offices, healthcare facilities, and schools without any issues.
Thanks to its performance, the Siguro AP-D400W Auk Air Purifier is perfect for any room up to 20m². Its CADR (Clean Air Delivery Rate), which indicates how quickly the purifier can clean a space of unwanted substances, is 139m³/h. You can use it anywhere without it disturbing you while you work or rest—the purifier operates at a noise level of 42–52dB, which is about the same as a standard refrigerator.
The touch panel is complemented by an LED display for easy operation.
The multi-layer HEPA 13 filter captures up to 99.97% of particles from the air.
Eliminates odours from the air (cigarette smoke, mould and more).
Control the purifier conveniently from your phone or tablet.
This air purifier also features a very high-quality multi-stage filtration system, including a HEPA 13 filter. It captures up to 99.97% of particles as small as 0.3 micrometres, which means that for every 10,000 particles the size of bacteria and viruses, this filtration system allows only 5 particles to pass through. The UV-C lamp then generates ultraviolet radiation with a wavelength of 270–280nm—breaking the DNA bonds of bacteria, thereby perfectly sterilising the air and removing cigarette smoke, mould odours and other smells. Last but not least, the purifier is equipped with an aroma box, allowing you to beautifully scent the room with essential oils.
You will certainly appreciate that the Siguro AP-D400W Auk has an ionisation mode that increases the efficiency of air purification—the ioniser generates negative ions that bind to unwanted particles in the air. A night mode is a matter of course, in which the purifier operates at the lowest possible fan speed, and all light and sound indicators are switched off, so you can enjoy undisturbed sleep in a healthy environment. The backlighting of the control panel can also be turned off manually at any time via a button.
Among other things, the Siguro AP-D400W Auk Air Purifier is equipped with a practical sensor for detecting air quality. This means that the device runs in fully automatic mode and will automatically increase its performance if the air quality worsens, and vice versa. You don't have to worry about a thing, just select the automatic mode and leave everything to the purifier. You can easily tell the current air quality in the room at a glance by looking at the quality indicator light located around the display, which can light up in four colours—green (very good quality), yellow (good), orange (average), red (poor).
A practical timer from 1 to 12 hours is also included. You can also regulate the fan speed in three levels. To control the air purifier, you can use the touch control panel with a backlit display directly on the body of the device or the TUYA mobile application, through which you can control the Siguro AP-D400W Auk from anywhere in your home.
