    Excellent value!!

    At first, I thought this unit was extremely noisy. Then I realised after reading the manual properly that I'd failed to remove the plastic film protecting the filters. Once set up correctly the unit worked with very little noise, even on it's loudest and most powerful setting. The unit looks nice and sleek, reasonably inoffensive to the eye, and is made of materials the look and feel of a premium nature. I was a particular fan of the touchpad operation and the ease of use overall. The unit has been used in small rooms, not large, but for me at least I think it's made a great difference. Very impressed.

    Really helps with hayfever

    The last few years, I've suffered from hayfever pretty badly. I have a pollen sensitivity which means that my troubles start very early in the year (Feb/March), and tend to go on for most of the summer. Coupled with the fact that I work from home and have two large birch trees right outside my window, it's a constant battle with my immune system.

    I've had this set-up at my desk for the past couple of weeks, and I'm pleased to say my symptoms have gone WAY down. I also leave it running overnight on 'medium', and when I get to work in the morning, the room feels fresher. Instead of popping daily Benadryl, I'm down to 1-2 a week, which is a huge improvement (I'm still getting *some* pollen due to windows being open on the warmer days... so this won't totally eliminate direct contact.). This air purifier really seems to be working.

    Style-wise, it looks like the kinda thing Apple would design. It's relatively large, but also quite neat in its design - I have it next to my computer and it almost looks like one of my speakers.There are three settings for speed. As mentioned, I normally keep it on 'medium' overnight, and 'high' during the day. The lowest setting is quiet - the highest is like a mild kitchen extractor fan and seems quite powerful. I've owned purifiers in the past that sound like jet engines, so this is a definitive improvement.

    It's also light, making it easy to move around the house, which is useful since I tend to work from different rooms.

    Looks really stilish and helps clear air.

    We have allergic son and struggle with dust in our home - carpets seem to attract so much of it, I do not know where this comes from! I only have the device for few days but it seems to does the job! Air seem to be cleaner, so great so far. It also looks really nice and of high quality, the panel with touch buttons looks also nice.
    Be careful before you make the first start - you need to unpack the filter and watch for mark on bottom lid to close properly (see pics).
    There will be ventilator to be heard even on lowest and night settings, so you might need to look for a place outside your bedroom if you are extremely noise sensitive.

    Neat Air purifier

    I've used this machine for a while now and I liked it. Its concept is simple, is to draw air from the bottom side, through a filter, then up comes the clean air. This process should entrap any pollen or dust particles. Its design is nice and elegant and not bulky.
    I live near a main road and I can say the air quality is not that great in the house. I have run the machine in a room with closed windows and the air was static, but after a while I felt I am breathing a fresher air.
    It has 3 fan speeds. The lowest is not noisy and I can sleep without any problems with it. There is also a sleep mode which will dim the display lights. There is a filter change indicator to let you know when it is due change.
    Tip: make sure you don’t start the machine immediately when you get it because the filter is inside a plastic bag. What you need to do is turn the machine upside down and rotate the bottom cover anti clockwise, then you will see the filter in the bag. Remove the bag, put the filter back, put the cover and turn it clockwise until it “Ticks” then you are ready to go.

    Last thing is you can plug this purifier into a switch timer or digital wifi switch, so it runs for a certain period of time and switches off automatically.
