I have a vax air purifier that has really helped my breathing. Sadly it is getting old now and i was toying with getting a new one. Then i saw an advert for a new type of air filter, a round one. It is more expensive so before i buy one i was wondering if anyone on here has one, if yes , how good do you find it. I am scared in case my current one breaks down as before i got it i was in real trouble and struggled every day to breathe.
Advice please if anyone has one.
