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.
