The 3M E-A-Rfit 393-1100 Dual-Ear Validation System is a professional-grade hearing protection fit-testing solution designed to take the guesswork out of workplace safety. Many employers ask whether standard earplugs or earmuffs are enough to protect their team, and this system provides clear, quantitative data that shows whether hearing protection devices are actually performing at the required level. Unlike basic field checks, the E-A-Rfit 393-1100 measures real-ear attenuation across a range of frequencies in just seconds, giving safety managers confidence that workers are receiving the protection promised by NRR ratings. For companies in construction, manufacturing, mining, or oil and gas, this is more than just compliance—it is about ensuring long-term hearing health, avoiding costly OSHA citations, and reducing workplace risks. Buyers often want to know if this system is complicated to use; the answer is no. It connects easily via USB to your computer, runs quick tests with microphone-equipped inserts, and delivers instant, printable reports for recordkeeping. By using this system as part of a hearing conservation program, businesses can train employees on proper earplug insertion techniques, identify workers at risk of inadequate fit, and demonstrate due diligence in safety audits. Enviro Safety Products, a trusted supplier of certified PPE solutions, provides the 3M E-A-Rfit 393-1100 with expert support, helping organizations improve safety outcomes while meeting regulatory standards.

Bought jackets for my employees who work for me and are required to wear reflective wear while out around airplanes. The temperature is getting cooler and wetter they need jackets that keep them dry. They were appreciative to get these. Ordering to arrival was incredibly fast. The people receiving these were surprised how fast they came when I took them in to them.
The fast shipping was the 2nd most impressive piece. The quality of the products are very high and pleasing as well.
When I went to your website to order the product I needed, it showed the correct photo and said nothing about the product being out of stock or discontinued. Instead of letting me know this, someone chose to send another similar part that will not work. The product I ordered wasn't expensive. In order to get them however, and meet the 50$ minimum, I purchased another item that I really did not need. When the product arrived, I contacted customer service and they promptly refunded the money for the wrong product. They provided the information that the product has been discontinued. So, in summary, I spent money that I did not want too, for a product I really didn't need and did not get what I really needed. All because the stocking/inventory system failed. The customer service representative was awesome and did evrerything he could to be helpful. So thank him for that.
Excelent
Everything went smoothly, as usual!
It was easy to order
Item took longer than advertised to ship. Once item arrived, it was determined to be incorrect size. I have reached out to Customer Service to initiate an exchange but no one has gotten back to me.
gloves are tight considering they are an extra large. i will be sending them back.
This site is listed on the 3M website as an official distributor. Product was reasonably priced, additional shipping charge wasn't that much, it shipped extremely fast (faster than estimate) and arrived decently packaged. The packaging couldn't be waterproofed, which I would have liked, but the boxes inside were undamaged. The delivery person, who is outside the companies control, sent me a picture that did not show the delivery. The post-purchase prompting for these reviews is a bit much, however. One message asking politely is standard, but I have received several at this point, so this is me leaving a review.
I always enjoy ordering from Envirosafety. I received my products in a timely matter.
Good fast service
Website was easy to navigate and order from. Turns out the size of the item I purchased was made to order not going to reach me in the initially stated timeframe and unfortunately not available until after the date I needed it by. The folks at EnviroSafetyProducts.com were very responsive, helpful and even cheerful in helping me cancel the order and getting a full refund. BEST customer service I've experienced online in a very long time if not ever. They will definitely be the first place I look next time I need a piece of safety equipment.
I was pleasantly surprised with the speed of delivery and the product. As a woman who is dealing with two cancers ( breast and CLL) it is important for me to feel safe IF I must go out in public during Covid/flu/RSV season and these are medical n95 masks not the fake stuff or industrial masks. Thank you for delivering my safety net
These goggles are something I purchase once a year for Jr. High students to use in science class. They love them and they work wonderfully.
Straightforward transactions. They have what I want and it arrives promptly every time.
