Blueair Blue Pure 511 Air Purifier With HEPASilent Combination Filter For Rooms Up To 38m² Removes 99.97% Particles Pollen, Dust, Mould, Bacteria, Viruses

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.

Very easy to set up and a lot quieter at night than I expected. It seems to be doing a good job so far for my room which is 12 square meters

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.

This air purifier looks very modern and smart. It’s decent size, light enough to lift should you need to move it, and very quiet. It can be heard on the high setting, but not annoyingly so. An improvement in air quality was obvious within minutes of turning it on.The outer cover is washable, and replaceable if necessary. The controls are very easy to use. The only downside in my opinion is the lack of any carry or grip handle. That’s ok if you are fully able bodied, but someone with arthritic hands, or a weak grip, would probably be unable to move if. This seems to be commonly lacking for dedicated air purifiers, whereas combined dehumidifier/air purifiers generally have some form of handle/grips. I imagine the lack of grip is to encourage people to buy one for each room.Overall, pleased with this item and would recommend.

Handy and small place next to bed. Noise level is low but it is hard to tell when you want to change the level, might need to press for a while or when you want to turn it off, you also need to press few times, which cause a bit inconvenience and might leave it on no realised. Also not sure when do I need to change the filter

Very effective, great design, does not create noise.

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.

Why did you choose this product over others?:The reviews seemed good! Don't believe them.It did its job well up until I went to move it, the plug dropped onto the cushioned lino, from 2-3ft and one of the pins snapped off!Amazon refuse to help, saying it is accidental damage. While in part yes, the plug accidentalally fell into the floor! But in 40 years I have NEVER NOT ONCE, had a pin snap on a plug, out of all the hundreds of plugs I have dropped, even onto hard flooring!I can now see how flimsy and brittle the quality of this plug is. And now I have a useless large ornament!
