I bought the JR Puralife P.30 air purifier because I had already owned a previous JR Ultra Juicer and was very happy so decided to get one of the JR Puralife models. It is very sleek, looks lovely in the Matt white design and works very well. Its extremely easy to use by just pressing the speed you want and also the sleep mode is very quiet, the machine can hardly be heard in this mode for night time. I suffer from allergies and hayfever, so I am hoping that this will help me all year round. I can definitely notice a difference in the air quality. Overall I am very impressed with the P.30 and also like that it came with an extra free filter, thats a nice touch by the company.
