This Blueair is their original model and continues to be one of their most sought after air purifiers. Its fine Swedish design and quality are responsible for the construction and performance that would be expected in an air cleaner costing much more. It is simple to operate and maintain and will clean a larger than average room.
- Unique filtration technology combines electrostatic and HEPA-like technology for a performance beyond most residential HEPA filters
- Polypropylene filter material is water-repellent and naturally retards mold and mildew growth eliminating the need for chemical-based bacteria or mold inhibitors that are used in most residential glass fiber HEPA filters
- Less filter restriction allows the Blueair to push more air volume through its filters than any other top HEPA machine, while operating at a reduced noise level
- Its high air flow: is great for quick cleaning and the lower, almost silent speeds provide the ideal operation level for continuous day or night use when you are in a room
- The award winning design of the Blueair 500 series is not only stylish and very efficient, it also allows for easy filter changes that take less than a minute of your time
- Safe use of electrostatic technology without producing ozone or off-gassing
- Durable steel construction: the grills and powder-coated steel exterior are easy to wipe clean, and won't pick up grime or oily stains the way plastics can, and they do not off-gas
- Filter Change Indicator: the 503 includes a magnetic timer that reminds you to change your filters every 6 months as recommended for optimal performance of your Blueair air purifier.
Summary:We highly recommend the Blueair 503 series for its quiet operation and ability to clean a larger than average room. We like the fact that one can run it on speed 3 to clean a large bedroom while operating at a noise level to not affect one’s sleep. We love Blueair's simple design and operation along with the steel construction and the simplicity of changing the filters. We feel Blueair should have included a separate pre-filter to extend the life of the main filter from 6 months to 1 year. Furthermore, filtration performance could be increased by an improvement in the seal between the filter and the housing to prevent some residual air flow by-passing which was evident when we measured the particle count of the air in certain locations. However, our overall impression of this air purifier warrants a 'very good plus' rating due to its cleaning performance by achieving a high number of air changes per hour while maintaining a quiet environment for those who are sensitive to noise. If you demand a quiet, reliable and simple to use air purifier for a medium to large size room, this product would be the choice.
