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.

Great product and recommended
I’ve had the 411 in the bedroom for a couple of years and very sensitive to noise when trying to sleep. No problems with this product as it is whisper quiet.

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.
