I got an email about testing out an air purifyer(sp)a while ago so i answered the add.
They emailed back the other day to say they will be sending me out the purifyer to test for them,i just have to fill out a questionaire when it arrives and one after i believe,they are also putting money towards the electric. Think it will be good as its due any day and the grass has just been cut so aware riley hayfever might kick in.
