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. The filter change indicator is a timer that counts down from 182 days (6 months). The timer is independent of actual run time. When 15 days remain to filter change, the blue LED light will flash. There is a snooze button that will let you turn it off for five days at a time. When 0 days remain, change the filters and reset the timer for another 182 days (6 months).
Low cost to run: energy star qualified and only requires as much energy as a single light bulb: 35 watts on low to 120 watts on high. (uses 35% less energy to operate than comparable units)
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
SurroundAir™ technology diffuses clean air gently: instead of discharging a windy stream of filtered air, the Blueair diffuses air gently through an area six times greater than the average air cleaner; operating on its lowest setting Blueair produces virtually no noticeable draft, while still providing an exceptional air exchange rate
Environmentally safe filter media: Blueair replaces standard triclosan-coated paper or glass filter fibers, which can harm the environment when released into the waste stream, with safer, nontoxic polypropylene. This revolutionary filter media is one of the least harmful plastics, producing only carbon dioxide and water as it decomposes - used filters are 100% recyclable, and release no toxins into landfills or the air
Filters resist contamination: because polypropylene is waterproof, Blueair filters naturally resist contamination from bacteria, viruses and mold, without chemical additives or weekly washes
Easy to change filters: simply open the lid, lift out the old filters and drop the new ones in - no screws, hooks or tools needed; Filters should be changed every 6 months
Certified Performance: each unit is tested and certified to deliver 99.97% filtration efficiency. Blueair air purifiers are durable and carry a 5-year limited warranty
Filter Change Indicator
How it Works:
Blueair 500 Series SurroundAir™ system achieves peak performance without annoying drafts by drawing in dirty air from the sides and bottom moving it through a less dense filter media, and releasing clean, filtered air from the sides and top.

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.
Pluses:
Unique filtration technology combines electrostatic and HEPA-like technology for a performance beyond most residential HEPA filters
Gas & Odor SmokeStop filters feature 5.3 lbs. of impregnated activated carbon providing sufficient removal of smoke, gases, odors, and VOCs
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.
Minuses:
Lack of a pre-filter to prevent dust build-up on the fan and inside the unit which are hard areas to clean; a pre-filter would also extend the life of the main filter by trapping the large particles and pet hair that quickly dirty a filter.
The filter life is short at 6 months and this is due to there not being a pre-filter and because the technology is both mechanical and electrostatic so the efficiency drops as the filter surface loads up with particulates.
The seating of the filters in the housing is not a tight seal and allows for some air to by-pass reducing the air cleaning efficiency.
It would be nice if it had an automatic setting including dust & odor sensors to regulate the fan speed
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. While the standard gas & particle filters are satisfactory for light residential chemical, gas and odor removal, we strongly recommend the Gas & Odor Smokestop filters if there are any internal factors such as off-gassing from new home construction like paint, carpeting, flooring, wood furniture, and upholstery. 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. Also, a pre-filter would protect the fan and inside from dust build-up which is inconvenient to clean. 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.
