Blue Pure 311

Hmm not seeing what you're seeing...I'm seeing $240, but ya your right, they are available so not discontinued at least. https://www.blueair.com/products/blue-pure-311i-plus-max?srsltid=AfmBOorh6W7WeKGc75U6aAXmYbFpzgRfiafao2ZBWp27ITb0yZrUabyH I'm glad too because you scared me for a sec.
