Product Review For Rayqueen Multi-Purpose Uv Sterilizer

Review of RayQueen Multi-purpose UV Sterilizer


There are enormous amount of various germs and bacteria found in common spaces and utensils that we used every single day. Most of us usually don’t think much about this since these germs and bacterias are invisible to us. However, the truth is that they exist in almost everything that we touched such as our mobile phones, cutlery, remote controls, cook wares, feeding bottles, wallets, books, utensils and etc.
This is where the award winning RayQueen Multi-purpose UV Sterilizer from South Korea comes into handy. RayQueen UV Sterilizer is a very popular household brand in Korea and widely used not only in homes but also in many food establishments in Korea.

Product Description

  • RayQueen UV Sterilizer is quite easy to operate. It uses high frequency UV-C light rays to kill or inactivate the micro-organisms. The unit comes with OSRAM HNS 6W Germicidal UV tube which is ozone-free and with low mercury content. The UV lamp, with a dominant wavelength of 254 nm, is very effective and environmental friendly disinfection without chemical.
  • Ease of maintenance and cleanliness is very important. The interior of RayQueen is made from great quality Hyundai BNG SS304 high quality Stainless Steel.
The model JHS-400 comes in a very generous volume, too. The wide space is designed to accommodate at least twelve (12) baby feeding bottles as well as other large items for sterilizing. We even sterilised a mid-sized lady leather handbag!

RayQueen JHS-400 comes with automatic ventilation. It comes with an internal ventilation fan that circulates fresh air throughout.

One distinct feature that stood out for RayQueen is its low-temperature sterilization. RayQueen employs a heated air drying method via PTC heater technology that keeps sterilisation at a maximum of 40 °C. At 40 °C, it will not change the shape of the object being sterilised but will make sure the object is completely dry at the same time. With PTC heaters, the energy consumption is very low at 90 W.

Other important features that the RayQueen UV steriliser has include very good and practical safety features. It comes with a tinted glass door that prevents excessive exposure to the UV-C ray, a door ON/OFF switch to stop sterilising if the door is opened halfway through, and an automatic overheating prevention device.

How to use the UV Sterilizer?

Operating RayQueen Sterilizer is real easy. There is only one rotating dial to operate. Just turn the dial to either left or right and press to select. The indicator will show the course selected and the countdown timer will start.
The unit comes with 3 different course of sterilization.
  • Course 1 – 10 minutes of full sterilization.

This course goes through a complete 10 minutes of UV sterilisation. Upon completion of 10 minutes, it continues to be on stand-by sterilisation mode. Every time the door is opened and closed, a 10 minutes of sterilisation begins.

Choose this course for objects such as mobile phones, remote controllers, papers, bags and etc. Use for dry objects only.

  • Course 2 – 20 minutes of drying + 10 minutes of sterilisation.

In this course, the first 20 minutes will be dedicated to drying the object inside the sterilizer. From the 21st to the 30th minute, it would sterilise the object using the UV lamp.

Choose this course for objects that have been washed but are still wet, such as feeding bottles, cutlery, plates, bibs, cups, toothbrushes, shavers, beauty tools, combs, cookware, etc.

  • Course 3 – 60 minutes in total (2 cycles of Course 2 as above)

It consists of 20 minutes of drying followed by 10 minutes of sterilization, and another similar cycle follows.

Choose this course for objects that are very wet and take a long time to dry, like towels, table rags, plush toys, dish cloths, baby pillows, etc.
