I was seriously thinking the air purifier idea would be a massive waste of my money, but was willing to try anything to stop me waking up groggy and clogged up every single morning (I run most mornings so it's not a good way to start for that!).
Since early May, I have had to blow my nose immediately after sitting up in bed, it's that bad. And I have felt groogy and rough every morning as well as this without fail.... 2 nights now with this -

I am actually shocked at the immediate difference its made and wondering why I never gave this a shot years ago.
No placebo or OTT reaction of thinking it is working, because it's quite bloody apparent that it is by the fact I can breathe again haha. £129 spent which at the time I could have kicked myself for, but now thinking £129 was some of the best money I have ever spent.
Now, I just need to fashion some strapping to carry it around on my back all summer and a way to portably power it and I am all set as a portable pollen kiling god!
