We Make The Invisible, Visible. As an Electronics Engineering Technologist, Rob Metzinger – SLT’s President and Founder – became extremely concerned about the interference of man-made electromagnetic fields (EMF) on the human body. Rob’s interest in EMF began in the year 2000, and Safe Living Technologies (SLT) was founded in 2006 – a time when wireless technology was beginning to boom, and without any caution or restraint. Rob furthered his education to become certified as a Building Biology Environmental Consultant (BBEC) and an Electromagnetic Radiation Specialist (EMRS) through the Building Biology Institute. He has been an educator and course developer in the advanced studies of EMF/EMR since 2008. He strives to be a leader in the field of education and advocacy around this complex issue. An alarming number of recent studies indicate that electrosmog has negative biological impacts. See our studies page and the Bio-Initiative Report for further details. It is in our best interest to minimize exposure to these invisible forces as much as possible.

For the past 5 years I woke up in the morning and had a feeling like I was in the microwave. I constantly felt exhausted and my mind wasn’t sharp enough to do any work. I couldn’t stay in my apartment for a long time during the day because I felt even worse, so I had be outside as much as I could.
I couldn’t figure out why the hell I felt that way because I have very healthy life style.
Recently I’ve traveled for 2 weeks and stayed in the national parks with a tent most of the nights. Rest in the nature without f…ing WIFI, cellphone towers, etc.
After the trip I felt re-born- full of energy, with clear mind, very productive all day long, with ability to wake up at 5am again.
After about 3 weeks living in the apartment I started to feel that those shitty symptoms are slowly coming back.
Then I recalled that I’ve heard something about horrible influence of WIFI, cellphone towers and other microwaves for humans. I researched the topic deeper and got the big picture of what is happening.
I bought this fabric, my wife made the bed canopy. After the first night I felt the difference. Since the canopy installation I don’t wake up at night, my mind is clear during the day and I feel much better. The fabric definitely works.
At least during the night my body is protected against the microwaves.
Thank you for developing and selling this fabric!

uW/m2 both peak and max values.
I could wish for a mode button to check for the different types: RF; LF; ELF (various levels)
I am a guy with eyes for details.

I bought 3 shielded power bars. Using an emf and electric field meter, I measured it's effectiveness. Turns out it's better than a 10 year old, 10$ power bar, but it's no more effective than a good quality APC power bar. Mind you the APC power bar also has surge protection, USB outlets, more outlets, and a flat head plug so it sits flush with the wall. And it's cheaper! Seeing that, I realized this thing is overrated as a product for emf protection. No issues with service. But given the high cost I thought I was actually getting something electrically unique, instead it seems like this product is just meeting the electrical standards. Moral of the story, don't use old and crappy power bars.

Zack has gone above and beyond the call of duty on every level, literally!
He has always been extremely helpful and caring while remaining very professional. Recently, when I needed help with a meter I had purchased from SLT, Zack took care of the whole process in a way that could not have been better in my opinion.
It is always a pleasure to work with Zack and he has definitely had a very positive impact on my relationship with Safe Living Technologies.

I appreciate the quality and breadth of EMF measuring/reducing products that SLT carries, but what truly sets them apart is their prompt and knowledgeable responses whenever I've needed assistance or have had a question -- personal service and expertise that can't be beat.

The time in which it was delivered. The ease of accepting it. And everything was transparent. Product is amazing.

They sell essential stuff, but they know what they've got. It's like someone charging you for water in a desert.Would you hand out water bottles for free all day in the desert? Anyway just pay the money and protect yourself and the kids. This is a hostile environment so take steps.

Kevin is always on top of it and makes things go right. He is great!
