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.

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.

Great at capturing dust that is in the room. Really easy to use and the lowest setting is silent! During summer this is perfect for someone with hay fever. Very easy to change to change filters too

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.

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

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.

Lovely air purifyer. Very light in weight plus really quiet. 3 settings

This is great, especially if you hayfever. The only problem with this product is that it is tricky to find a replacement sleeve. Overall very quiet and does it's job.
