Hi there, Hi there, Decided to get rid of our another two blueair purifiers. Model 450E & 403, bought them together with our other blueair purifiers 10 months ago. The current fitlers have been changed a bit over three months ago, so they are good for at least another 2 months. Both air cleaners are in mint condition. Retail price 450E for RMB 6400 Asking for 3800 RMB with current 2 months filters + a brand new filter ( value of 600 RMB ) still sealed in it's original package. Retail price 403 for RMB 5600 Asking for 3500 RMB with current 2 months filter + a brand new filter ( value of 600 RMB ) still sealed in it's original package. If you are interested and agree with the price.
