Review: Great Air Purifier - Seems to be working great, keeps the room cool and smelling fresh. Very easy to use, only two touch sensitive buttons. It’s bigger than I anticipated but feel like that’s good value for the price. I can hear the lowest setting at night but it’s like a low white noise so i don’t mind.
Review: Good product. - Was recommended this air purifier by my son in law . I’m having building work done and this really helps keep my rooms dust free . I ended up buying a second one as it was on offer at the time. On the lowest setting it’s quiet enough to leave running. On the highest setting the noise is noticeable, but handy to use to have the air feel and smell fresh quickly. It’s portable and actually easy enough to move from room to room. I have one in the bedroom and one in the living room. The rest of the house smells quite dusty at the moment with the ongoing renovations , the this air purifier works well enough to keep the rooms it’s in smelling fresh and dust free.

## Questions & Answers

**Q: Does it have a true hepa filter**
A: No it doesn’t. It’s less dense than hepa, which they claim is as good.

**Q: Do you wash pre filter on particular wash cycle..?**
A: I wash mine once a month on a normal 40 degree colour wash and it comes out great. Ive had the purifier (411) for a couple of years and no wear in cover. I dont tumble dry though just air dry.

**Q: Is there any other colours available? As I can only see one option of Diva blue**
A: Yes, there are two other options available: saffron red and dark shadow.

**Q: If i turn it off at the mains while its on, and switch the mains back on, will it automatically turn back on, or do i have to press the button again?**
A: You can turn it on and off with the mains socket switch. The purifier has a knob you turn for 3 positions, it clicks and stays there even if you turn off at the mains.
