BLUEAIRBlue Pure 511 Air Purifier With HEPASilent Combination Filter For Rooms Up To 38m² Removes 99.97% Particles Pollen, Dust, Mould, Bacteria, Viruses | Activated Carbon Reduces VOCs, Odours

I purchased this via Amazon 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.

I was doubtful when I purchased on just how good this thing could be. But I have to say I went in with low expectations and was actually left amazed with just how good and effective it is. You can smell the difference and can clear a decent sized stuffy room in under 20mins

I found the air purifier difficult to operate. The instructions are to press the the on/off and speed buttons but I eventually discovered that a light tap was a better option.Very quiet in night mode. Does not disturb sleep. Definitely makes the bedroom cooler so waiting to see whether I will use it in winter.As a hayfever and allergic rhinitis sufferer I am not having as many sneezing sessions in the night but still feel congested when waking.Overall still trying to decide how enthusiastic I am about this product.

A replacement for the same model, which had worked well. Id have preferred a more up to date model but to find replacement filters for any of them is a problem. Found some for only this one from another source, so invested in four as then the device should last two years. Recipient reported an ease in her breathin difficulties.

The media could not be loaded. Half and half either loud and works very well, makes the room colder as the fan at the top lets out a lot of cold air. Or put the speed slower and cannot tell it’s on, may still be working but it’s rated to do a room of 16m2 that’s what is stated on the box when you receive and as my room if around 32 hence why I ordered this for it to work it would have to stay on max as the power is around 16w which would be good for a small room kids but struggle in a master bedroom or large room

I ordered wrong item air purifier was OK just to large for my flat

I am definitely returning this. So sad

very good quality
