## Description

Highly effective air purifier removes 99.97% of particles as small as 0.1 microns, including viruses, smoke, and allergens. Operates quietly at only 24dB on low speed.

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: Clean air and a nice breeze - I purchased this via desertcart as it was on offer, so significantly cheaper the John Lewis. Honestly, the quality and air purification is incredible. Before this, members of my household were continuously sick. Now, we see very few problems. The dust and fluff it picks up weekly, shocks me. The purifier has 3 settings. Sleep mode, medium and high. We set the purifier to high when away and use sleep mode during the night. The noise is barely noticeable in sleep mode but I still wake up feeling fresher than before. It’s energy efficient too. I never turn it off and I’ve seen near enough no change in my energy bill. This purifier only works across the space of a standard room. You would require around 1 purifier per room to clear the house/apartment. The product is far cheaper than other mainstream purifiers and does a fantastic job. I would say the outer filter needs cleaning fortnightly and the main filter every 6 months. The blue air purifier does warn you that the main filter requires changing by showing a solid red light on the top console.

## 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.
