While some might consider Blueair Classic 603 air purifier design modern and sleek, it is actually quite conventional looking at certain angles. Carry around the unit is no easy task then again there are 4 casters right at the bottom for easy moving. Made with galvanized steel, it is very durable and can be clean easily unlike most air purifiers that used cheap plastics. Designed to allow a great volume air particles, there are multiple air inlet around the air purifier from front to side.

Final thoughts on Blueair Classic 603

By now we should be familiar with Blueair reputable offering and 603 is no exception. With its superior all-rounded performance and good noise filtering (not at the highest setting), no doubt this is another winner in our list. But the real question is among the 3 air purifier: the Blueair 503, 603 and 650E, which air purifier should you go for? Most people would recommend the highest series which is the Blueair 650E if money is not an issue; I will, however recommend to go for air purifier that can provide sufficient applicable area that is within your requirement as there is no point getting a powerful air purifier that you have no use of.
