Negative Ion Air Purifier, Plug In or USB Model

It goes in the socket behind the door, the little green line comes on, and that is the whole interaction.

There is no tank to fill, no cartridge to slot in and no app to pair. The mains version is a flat oval about the size of a phone, moulded in a soft matte ABS and PP shell with a single recessed power button at the top and a thin status line low on the face. It ships with either a United States or a European plug, and the body comes in Chinese Red, fresh green, powder pink, classic black or elegant white.

The USB version is a different object entirely, and worth knowing about before you order. It is an arch, an open loop standing on an oval foot with the connector below, and it comes in seven colours: Blue, Green, Pink, Black, White, Orange and Purple. Same maker, same ion generator inside, completely different shape and completely different power.

Key Benefits

• Two physically different models under one listing A flat oval that lives in a wall socket, or an arch shaped unit that runs from a USB port. Read the option name, not just the colour.
• Nothing to replace, ever The maker lists no filter, no cartridge and no consumable of any kind. The packing list is the unit and its cable, and that is all there is.
• Under 36 dB The maker rates it below 36 dB, quiet enough to leave running in a bedroom or a home office without noticing it.
• 50 cubic metres per hour The maker rates the air volume at 50 cubic metres per hour, with an applicable area of about 10 square metres, sized for a small room.
• One button, no menus A push button on the unit and a status light. No remote, no app, no wireless connection of any kind is fitted.
• Twelve colourways across the two models Five on the mains oval, seven on the USB arch, all flat matte finishes with no printed pattern.

Best for: a small bedroom, a home office corner or a bathroom where the socket is free and you want a device that does one thing quietly and never asks you to buy anything again.

Why It Works

It is an ion generator in a moulded shell, drawing power from a wall socket or a USB port and running a quiet emitter behind a single status light. The maker publishes three figures for it: an air volume of 50 cubic metres per hour, a noise level below 36 dB, and an applicable area of about 10 square metres, so it is sized for a bedroom, a home office corner or a bathroom. There is nothing to fill and nothing to replace, and it moves from room to room with you: unplug it, carry it, plug it in again. For fresh air, open a window as you normally would and let this run quietly in the background.

Quick Product Facts: Working principle negative ion generation per the maker; shell material ABS and PP; two models, a flat oval mains unit with a United States or European plug, and an arch shaped USB unit; control a single push button with a status light; air volume 50 cubic metres per hour per the maker; noise below 36 dB per the maker; applicable area about 10 square metres per the maker; no filter, cartridge or consumable listed by the maker; no remote, app or wireless connection fitted; twelve colourways across the two models; packing list one unit and one power cable.

How It Fits Your Routine

Choose the model before the colour, because they are not the same object. If the socket behind the bedside table is free, take the mains oval and check you are ordering the plug standard for your country. If the only spare power is a USB port on a desk hub or a charger, take the arch.

In use it is genuinely set and forget. Press the button, watch for the status light, and leave it. There is nothing to clean out and nothing to top up. Wipe the shell with a dry cloth when you dust the shelf it sits on.

If you move house or change rooms, unplug it and take it. Nothing is mounted, nothing is drilled and no adhesive is involved, so the socket you leave behind looks exactly as it did.

FAQ

Does it have a filter I will need to buy? No. The maker lists no filter, no cartridge and no replacement part anywhere, and the packing list is the unit plus its cable. Nothing is sold to go with it.

How does it work? It runs as a negative ion generator, the working principle the maker states, drawing power from a wall socket or a USB port and running quietly at under 36 dB. Give the room its usual fresh air from an open window and let this sit and run in the background.

Which model am I ordering? Read the option carefully. Options naming a United States or European standard plug are the flat oval mains unit. The option reading new USB regardless of the plug is the arch shaped USB unit, which is a different shape and a different size.

Is there an app or a remote? No. There is one push button on the unit and a status light. No wireless connection of any kind is fitted, so nothing pairs with a phone.
