The EI Wellspring

Practical Tips for Coping with
Chemical and Electrical Hypersensitivity

About This Site

This website’s primary purpose is to provide practical information for people with severe multiple chemical sensitivity (MCS) and electromagnetic hypersensitivity (EHS/ES). MCS and EHS are closely related illnesses, which together are referred to as Environmental Illness (EI).

The information presented reflects the experience and opinions of individuals who wish to help others. Naturally, what works for one person may not work for another. The reader should evaluate the suggestions in the context of his or her own situation, and apply good judgment and common sense before following suggestions presented.

We are based in the United States. Most of our readers are in North America, but our site is accessed from more than a hundred countries each month. We therefore try to make our articles globally relevant. We are aware that building codes, practices and product availability can vary by country.

The information here may seem extreme to people who do not have severe environmental illness. We do not suggest these measures be used by those who do not need it, just as it makes no sense to ban pollen because many people are allergic to it. Of course, common sense is always a good idea. Children and pregnant women should avoid toxic chemicals and never use wireless gadgets — even though this seems like a tall order.

Products mentioned

This is a non-profit website. Vendors and products are mentioned in some articles, but that is based on merit. We accept no advertising, no paid product endorsements and no sponsored content.

It is our opinion that some products advertised to people with environmental illnesses are of very dubious value. We have also heard many credible stories where a product has been helpful to some and harmful to others. We thus urge caution and healthy skepticism. Try a little of a product first before committing yourself, especially if a failure will be expensive or have severe consequences. Some people have literally lost their homes because they didn't test a "safe" product first.

We also suggest a healthy skepticism towards any expert in this area, whether they are paid or not. There are still several issues that are not fully understood and nobody has all the answers. Be especially skeptical when the expert sells a particular product, as it is easy for them to see it as a solution to "all" problems.

About our authors

The vast majority of our articles are written by people with a degree in engineering or other scientific backgrounds. Most articles are about the author's personal experience, or otherwise about an area the author has experience in.

We do not believe any of our authors have conflicts of interest, unless one is stated.

Some of our authors wish to be anonymous, but their identity is known to the site management.

For our readers with electrical sensitivities

Many people with severe EHS/ES are unable to use a computer and the Internet, yet unfortunately there doesn’t seem to be a good alternative way to make the information available inexpensively. To help those who can't use a computer, the site and its articles were designed so that a helper can print out the menus and articles for the EHS sufferer to read and select from. Most documents are available in Acrobat format (PDF), which should be universally printable.

Due to staffing and funding limitations, we are unable to offer paper copies through the mail. We are also unable to answer questions at this time. The issues facing people with EHS are sometimes more complex than the issues that pertain purely to MCS. Consequently, many of the subjects pertaining to EHS are more technical in nature than the other articles are. Everyday language is encouraged in the articles, but some simply do require a level of practical experience to be useful.

Readers with slow internet service

Some of our readers have slow internet service, so we try to make the HTML version of our documents fast to download. Some web browsers have the option to not download pictures, unless they are clicked upon. Choosing this option can help.


We do not accept any advertising. We have no ads, no sponsored content, no sponsored links, no product placement, etc. The management of this site does not offer any paid consulting services, nor has any commercial interest in any product.
