Excel MX-99 Water Ionizer


The Excel MX-99 water ionizer is made by the Impart Group in Japan and is an upgrade of the Excel IE-900. [See below, for see more about the Impart Group.] It's a great-quality water ionizer and will give you many years of fantastic ionized water.

The MX-99 water ionizer will give a wide range of pH and ORP, produced by adding salt into the electolysis chamber.

The Impart Excel MX-99 is one of the most respected Japanese water ionizers. For alkaline drinking levels of ionized water it will easily produce the pH you need [between 8.5 and 9.5], but the MX-99 will also produce more strong alkaline water for cleaning purposes, especially if you add salt. [Note: Adding salt to the source water of a water ionizer can cause eventual corrosion of the plates if you don't properly rinse out the water ionizer after each use of salt.]

Features of the Excel MX-99 Water Ionizer

* Built in temperature sensor
* Microcomputer monitored flow rate
* Makes super acidic water, as low as 2.5 pH, using common table salt
* Automatic self-cleaning electrolysis chamber
* Antibacterial activated charcoal filter
* Five large platinum coated titanium electrolysis plates

Note: All pH and ORP levels are approximate, depending on local water supply, because water ionizers don't always work the same in every location.

The Toyo Metal company split into two companies: Enagic and Imparte Group. The original engineers from Toyo moved out on their own to operate under a new name called the Impart Group. The MX-99 represents the best achievement of these Japanese experts. They claim it is better than the SD-501.

Impart water ionizers come with a 30-day satisfaction warranty, with a 15% restocking fee if returned.


The MX-99 comes with 5 large platinum coated titanium electrolysis plates. The makers of the Excel MX-99 has refused to add more plates than this. Their extensive testing and experience in making water ionizers has taught them that more plates does not make a better machine. The MX-99 already comes with 8 slots, but only 5 slots are occupied with plates. The engineers claim that the spacing between the plates is important to the overall performance and durability of their water ionizer.

Medical Recognition:

The Excel MX-99 is recognized by the Japanese government as a medical device. The medical device approval number is 219AK8ZX00147000 JAPAN
