Original is Best

The original hepa filters work the best and last very long. I replace the carbon one every 3 - 4 months; the main fillter last 8 - 10 months. Glad the red light comes on to remind changing the main filter.

Easy and effective to use.

The filter has a good " change me" signal. It is very easy to change out. I think it does a good job.
