I suffer from tonsilitis and the particles in the air seem to affect it quite a bit, so i decided to get an air purifierto see if it helped alleviate the problem.
I looked in Argos and there it was £50! I finally got mine on ebay for around £25.
Basically this air purifier has a HEPA filter and an Ioniser. The air is sucked in through the filter, catching any particles and is blown out the other end over the ioniser, the ioniser supposedly changes the charge of the particles in the air so they attract more particles making it heavier, then it drops back down an is easier to be caught by the filter. supposedly.
The unit is small enough to keep on a desk or bedside unit but it is still pretty bulky, i keep mine tucked in the corner. There are 3 speed settings for the fan, slow ('silent mode', med and fast) the silent mode is bearable at night but then i am quite a heavy sleeper and have never had any problems with it keeping me awake. All you need to do is plug it in at the mains choose your speed setting and turn the ionizer on and you are off.
As well as the hepa filter there is a secondary filter that is a kind of plastic like substance and this can be washed, but the HEPA filters need to be changed about every 6 or 7 months (if you use it alot)
So does it really work? Personally, i think it does. Sometimes i will leave it on throught the day in my room and when i get back in the room feels 'fresher' it is hard to describe, but something feels different. But i do think the ionizer is a bit of a gimmick. Although for the price (usually £50) i dont really think it is worth the money. Plus the replacement HEPA filters are quite expensive.
If you want to spend that much go ahead, it does work but it is a pretty steep price considering what it is.
