I bought this from JB Hi Fi last week as bushfire smoke from weeks of backburning has been seeping into my bedroom each night, in old house with old windows. This has done a fantastic job of cleaning the air in our home, is easy to move from room to room. On level 1 and level 2 is hardly audible. Level 3 is a bit noisy but that's ok. Can set to 2 hour, 4 hour, 8 hour. Includes an air ioniser function which makes the air feel really clean and fresh. where we are in the Blue Mountains

Everytime I turn it on, the result is instant I find myself breathing much easier and feel the refreshing of the air. The reason I bought this is because my husband is allergic to dustmite and has sneeze attack out of the blue sometimes. The pros is easy to use, easy to clean the filters, and also it has colour indicator telling you the air quality (red means bad, pink is average and blue means good). Cons is the flat control screen isnt quite responsive sometimes. But overall this purifier really helps improving the air quality of the room.
