How do I reset my filter replacement indicator (red light) on my Blue Pure air purifier?

A red filter replacement indicator appears on the air purifier when it is time to change filter, after about 6 months of operation.

After you replace your filter, press the center button down to reset the filter light indicator until the red light disappears. It usually takes 7-10 seconds and may take up to 30 seconds depending on the model.

Filter recharge
Blue Air Filters come right on time. The filter I replace is filthy and the new filter looks so pristine at the moment. The Blue Air machine though, will be doing its job and cleaning the air in my living room and in 6 months will look like the old filter this month. This is a great air cleaner and I love that I don’t have to remember to send for a new filter. Thanks Blue Air.

Great Ait Purifier
We have been using our Blue Pure 311 purifier since Covid came around in 2020. It is so quiet, we don’t even notice it. And it does a great job. One of the best purchases we have made for our health.
