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.

The sound quality was not good. Sounds muffled or like its coming through a tube but still thankful its safer for long use.

So far I found it a very easy and affordable way to test my home for Radon. Easy to order, delivery was fast, very very easy to place Radon Monitor and now after 90 plus days I can return Monitor to Safe Living Labratories in the supplied self addressed envelope for analysis. Test results will be supplied back ASAP. How much more simpler and easy can it be made to test for Radon.

I love that SLT has an option for a free consulting call. I used that call to determine what product might help me avoid EMF radiation when I travel. I ended up buying the blanket that blocks EMFs and I will try it out on my next trip. I am hoping it will help me sleep in high EMF areas (hotels, AirBnBs etc.) as currently that has been my biggest issue. I bought an EMF meter from SLT years ago, and I have used it to reduce the EMF radiation in my house. Amazingly you can't just turn off the wireless router and be EMF free, my carrier (Xfinity) had four more "hidden" hotspots that I would not have detected without my meter.

The Pro II RF Meter is an excellent product, and I recommend it to anyone who is interested in taking responsibility for their health. It's accurate, and user-friendly plus shipping was fast. Much appreciated!

The Safe and Sound classic III is a great machine, I've gotten very accurate readings from it. The customer service is also excellent. I had an issue with something else and the representative Kevin had a great attitude and willingness to make things right which he did 100%. The company is legit and easy to communicate and work with.

I recently placed a high-value order (+USD $5K) with Safe Living Technologies, and the experience was flawless. As someone who deals with international logistics, I was incredibly impressed by their shipping efficiency. Despite the order being large and heavy, they utilized FedEx Economy and CUSMA documentation perfectly, keeping my shipping costs to the US remarkably low.
Beyond the logistics, their support is top-notch. When a cable arrived DOA (Dead on Arrival), they didn't hesitate or make me jump through hoops—they shipped a replacement immediately. It is rare to find a company that balances technical product excellence with such a high level of customer care. Highly recommended.
