-I have always only cooked in cast iron and all of my cutting boards are wooden.

-I only drink my own well water.

-Not only do I avoid smokers, I won't make eye contact, LOL. When the mood stikes me, I even have a wee drama that I enact for them wherein I drag my brood of children away whilst coughing and exclaiming "Dear Cthulhu, how awfull! Kids, hold your breath!" Just to irritate/draw attention to said smokers as much as possible. (my children think it's hysterical and play it to the max) ;p

-Shampoo, toothpaste, deodorant, lotion, and soap free, me. ;)

-I clean my entire house with only a broom, white vinegar, and baking soda (and a lot of scrubbing!) The one exception is that I do keep a bottle of old fashioned Lysol for sick-room applications.

These are not environmental toxins, but, I have also tried to eliminate caffeine, aspartame, NSAIDS, analgesics, etc, to try to give my poor liver a break.

-Replaced my plastic cutting board with a wooden one

-Bought a good HEPA vacuum to gather dust that may accumulate toxins from my low quality Walmart furniture (although I haven't vacuumed in several months)

-Bought an air purifier because I live next to a highway

-About to buy stainless steel bowls to carry my lunch in (maybe a Bento box?)

-Ditched my radiation-emitting smartphone in favor of messenger hawk

I use a Klean Kanteen for water (I don't even accept "free" plastic-encased water), I'm mostly shampoo-less and soap-less and tooth paste-less.

Avoid unfiltered tap water. It can be full of toxic chemicals, heavy metals, and other dangerous substances.

• I generally don't drink out of plastic anything. I use a Mason Jar at work.
• Fluoride and Glycerin Free Toothpaste
• Water filter that gets Fluoride, Pharmaceuticals, etc out of my water
• Obviously, no processed foods - I also buy only pastured animals.

While I do these things at home I am not crazy about them. When I eat out I pay less attention. You body has an amazing ability to detoxify as long as its not doing so all day, every day.

Sodium lauryl sulfate free soap, shampoo, toothpaste.

Ceramic coffee cup.

Filters for water and shower.

I wrote about this a few months ago and there may be some tidbits that you'll find helpful... "Get off the Plastic Bottle"

• I only drink out of glass, boiled and filtered tap water
• I substitute toothpaste, shampoo, deodorant, lotion with various oils and baking soda
• The cats get pine pellet litter
• I clean around the house with a vacuum, vinegar and baking soda
• All detergents replaced with castille soap, borax and washing powder
• At night when I sleep, my phone is off and at the other end of the house
• Cloth menstrual pads (disposable ones are treated with chlorine, tampon fibres get left behind up there)
• All food organic, local if possible

An incomplete list:

• Avoid plastic as much as possible. Use a stainless steel water bottle, glass containers for food, etc.
• Cook a lot in bare cast iron.
• No shampoo, sunscreen, moisturizer, soap, lotion, chapstick, shaving cream, toothpaste, or anything like that.
• Use a detergent labeled "all natural ingredients". I've tried washing my clothes without detergent and it didn't work. No idea what this detergent is made out of, but at least they make an effort to make it out of harmless chemicals.
• Be outside in the "wild" as much as I can. Spend as little time as feasible sitting in front of a computer, in a building, in a car, or whatever.
• Only drink well water.

None of this is limiting either. It's more liberating than anything else. Healthy too.

• Shampoo free, ultra-natural oil based conditioner or ACV
• Dr.Bronner's for soap, laundry, general cleaning
• Crystal deodorant stick, although I do still use Tom's of Maine deodorant some days
• Almost all food organic, all meats pastured, most local
• Fluoride free toothpaste
• Replaced plastic food containers/water bottle with glass
• Have tried to reduce dependence on artificial lighting, replaced several lightbulbs with low wattage amber bulbs
• Went off the pill and switched to copper IUD, organic cotton tampons, and then to a silicone menstrual cup

I don't avoid processed food completely, but have limited it significantly.

Yes to all of the ones you listed. Plus made my own pomade and had an air filter for my apartment when I lived in Los Angeles
