If you interested in being “Green”, the BlueAir 501 is very friendly to the environment. The plastic the filter is made from is the least toxic they could use, which is better when we talk of disposing of the used filters and you won’t have to worry about the filter off-gassing some toxins. Another problem with filters in some cleaners is the mold and bacteria that builds up. The BlueAir 501 filter is waterproof and also biodegradable when they are thrown away.

To talk about the BlueAir 501, you have to mention the quietness of it while in operation.  With 4 speed settings, the lowest is so quiet, they named it HEPASilent, and at that setting you can barely hear it it running.   Even the next level setting is quiet compared to most machines of this caliber.  When you move up to the 4th setting, it is really moving some air, but still it could be called tolerable.

This system can also do a good job at distributing the air throughout the room, no dead spots that don’t get filtered. It actually looks pretty trendy and it won’t be something you feel you have to hide behind the sofa. The designers put some effort into making this model look good. Maintaining this system is simple and easy, as there are no tools needed. To change the filter, you can just open up the cover, take out the old one, and snap in the new.

You can buy an additional kit to add to the filtering capabilities for smoke. And it comes with a 10 year warranty, but I doubt you will be needing it. This is built strong. Anyone who has Asthma, respiratory conditions, or allergies will benefit from having the clean air to breathe from the BlueAir 501 air purifier.
