Blue Pure 411 Series Particle + Carbon Filter

Happy with the filter

We’ve been using the smaller air filter in a home dialysis room to keep it as clean as possible to avoid infection. It’s working well. I appreciate the simple design. It’s easy to change.

The easiest air purifier

I love the simple on button, 3 speed fan on my 411 air purifier. I have had this since 2020 and it is still going strong thanks to the red light alert to remind me it is time to change the carbon filter.
