The chlorine filters are easy to attach. They just go between the pipe and the shower head and are inexpensive. About 30 dollars. Very good investment because we can absorb more chlorine from a shower or bath that we can from drinking tap water all day.
For people recovering from MCS or any total load issue, it is a must.
More advice? Keep the load down. Stay away from most supplements. They are harder on your liver than any derived benefit. Keep it clean, pure and simple. Food type supplements are the best such as greens etc. For minerals, juicing is excellent, especially wheatgrass grown outdoors with oceangrown water. This will supply incredible minerals that will be assimilated. Another option is to use angstrom minerals, which are very bio available.
The key is to get good flow in your organs starting with the bowels, then the liver. There are some great cleanses for this when you are ready. Do a search on all my messages where I get into more details about this.
Raw organic living food will take you to the next level of health.
