This machine is really a masterpiece. I really recommend this product.

It was simple to order and install, the machine gave it's indicator to replace the filter and stopped operating when the filter was clogged. Was wondering if one would be able to make out difference between the new and used filter. The difference between the new fresh filter was visible compared to the use the discoloured old filter. Simple instructions available online. Did not need to call any service technician to resolve.
