help me navigate air purifiers

[peony68]

We live in a 3 bedroom terraced house on a fairly busy road . I've been researching how to reduce the monumental amount of dust living on such a road produces in our home , not to mention the interesting aromas in our teenagers bedrooms and fumes from passing traffic when the windows are open .
Air purifiers seem to be the answer to my air quality problems , but there are just sooooooo many different ones . So I'm turning to the wise people of mumsnet for your advice and reccomendations , would probably work best for us to have a small one in each room as teens seem to have a severe aversion to leaving their doors open !!!

I started my search at Allergy U.K. as they have an endorsed range which are proven to tackle dust, mould and pollen particles.
I have this one, which is at the cheaper end. It has a tray to add scented oils.
I’m very happy with it:

‘Which’ also have a range of reviews on air purifiers if you subscribe to them.

I have a Vax AP03. Very pleased with it. It does a bedroom very well. It's not super small and it does have a fan like noise, but I tend to put it on when I am not in the room. It definitely freshens the air. We had painters doing the halls and I had terrible headaches, it really helped then. I also use it if I am feeling chesty.

I actually bought it on ebay, it was about 150. I don't always use it, but the times I do, its helped or comforted.

Bought one from lidl a few weeks ago for £30. Works well.
