Doesn't seem to make much of a difference. I bought for my bedroom. It's a little fresher and It's a little noisy, even on quiet mode. It has an ioniser function, which I have no way of seeing if it is working . I had one years ago that worked well. It also has a basic set timer 2, 4 & 8 hrs. Despite all the hype, would I recommend buying it? I really don't know. May be I need something more powerful to eradicate the presence of Toxic gas.

Hasn’t cleared out any dust particles from our bedroom at all, and we’ve had it on full whack for the the last 2 days. Will probably return it since it doesn’t actually do anything. Besides, it makes a bloody racket

Works well and does the job as it should in a house with cats. Problem is finding filters. I do come across them but they are often out of stock and can be pricey. May consider replacing it in time.

Purchased the unit in Nov 2017 and it seemed to function well; however given a fire we needed to replace the HEPA filter.However, as it turns out it is discontinued model and there are no filters on Amazon/ web. When we called the manufacturer, they simply suggested we purchase a newer model!?!Be aware, you are spend the money on a "single use" unit.

Worked well initially. Had to return product as stop/start button shorted and allowed current to flow when off.

The UV lamp failed after approx 8 months and I get a reply that the lamp is not available. No UV lamp means no UV filtration. This air purifier cannot be maintained if there are no supplies of the UV lamp from the UK. No UV lamp changes this air purifier to Not Fit for Purpose! With no lamp I suggest that this product should be avoided!
