  • The 3M E-A-Rfit Dual-Ear Validation System helps employers verify whether the hearing conservation product that a worker is using is providing adequate protection.

The 3M E-A-Rfit Dual-Ear Validation System uses F-MIRE (Field Microphone-In-Real-Ear) technology to generate a Personal Attenuation Rating (PAR). The system measures the effectiveness of the hearing protection from inside the employee's ear to provide accurate quantitative results.

The 3M E-A-Rfit Dual-Ear Validation System helps employers verify whether the hearing conservation product that a worker is using is providing adequate protection. This objective fit testing system provides a personal attenuation rating (PAR) for each worker. In just seconds, it measures across 7 standard frequencies, quickly reporting whether their hearing protectors (earplugs, banded, or earmuffs) are effectively blocking the individual worker from potentially hazardous workplace noise. Once every employees personal attenuation rating is known, health and safety professionals can utilize this data to enhance their hearing conservation program. 

  • Capable of testing earmuffs and earplugs
  • Tests at 7 frequencies from 12Hz to 8000Hz

Suggested Applications

  • Delivers a quantitative measurement of personal noise reduction for each employee
  • Can help identify whether or not the employee has adequate protection

Parts fit perfectly
Size: 21 Pcs for eufy X10 Pro Omni
This is a good price for replacement parts needed for my EUFY 10 series robovac. I changed all of the parts that were needed and the replacements fit perfectly and were easy to change be following the instructions from the manufacture

Literally a lifesaver
Size: 21 Pcs for eufy X10 Pro Omni
This was actually a lifesaver for me because my UV was starting to act weird after like a year of using it and my dog sheds a lot. I couldn’t really figure out why it was sending me so many notifications and then once I bought the spare parts kit, everything went away and the thing was acting like how I got it when I first got it and it was cleaning everything really good and thoroughly and it wasn’t acting weird and like running in circles so make sure you take care of your robot vacuums.

Replacement Roller brush for my robovac
when you have long-haired dogs... these rollers WILL get tangled up with yards of hair...and although you can (and we do) take them out...and clean them off, after a while, the design of the roller is changed because of these tangles... This replacement roller is great, easy to install, and cost effective. would recommend if for no other reason, than keeping my house cleaner

Fits Perfect
This fits my cordless P10 Pro perfectly. It has some foam and hard grooves for picking up debris. The part feels very solid, not cheap or low quality at all. Be sure your Dreame is one of the models listed as this only fits those. It won't fit any of the other brands that share some of the Dreame parts (like Mova, for example). The rollers do eventually wear and reduce performance. This is a nice alternative to the name brand.

Perfect Fit & Performance
Style: with Pre-Filter
These are an excellent, cost-effective alternative to OEM parts. The brushes and filters fit securely, restore full suction power, and hold up well to daily use. A must-have for maintaining a Eufy RoboVac without the high brand-name price tag.
