Yes. Life+ uses a filtered attenuation design, not a complete seal. It reduces the damaging low-frequency noise of drills and suction motors while preserving high-frequency sound clarity, including speech, alerts, and patient responses. Think of it as a volume reduction rather than a mute. You remain fully aware of your clinical environment.

UK occupational guidelines (Control of Noise at Work Regulations 2005) set the lower exposure action value at 80 dB and the upper at 85 dB. A dental drill operates between 85 and 100 dB depending on instrument and technique. A 24 dB reduction brings that exposure down to 61 to 76 dB, comfortably within the safe daily limit. The figure is independently certified by PZT GmbH, Notified Body No. 1974, across more than 1,700 standardised tests.

Yes. Life+ is made from medical-grade silicone that is BPA-free, PVC-free, and latex-free. It is designed for extended, daily wear without causing skin irritation, allergic response, or discomfort. Many of our customers wear them for full eight-hour shifts.

Foam earplugs provide high attenuation but block sound indiscriminately and are uncomfortable for extended wear. They also degrade quickly, require constant replacement, and generate significant clinical waste. Life+ provides precision-filtered attenuation, lasts up to 100 uses per pair, and at 30p per use costs substantially less over time. The silicone construction also maintains a consistent seal throughout a full shift, which foam does not.

Yes, and many dental professionals use the same pair for both. The patented 2-lamella conical shape sits completely flush against the ear with no protruding stem, so there is no pressure point when lying on your side. It blocks low-frequency noise — traffic, air conditioning, a partner snoring — while still letting high-frequency sounds like alarm tones pass through clearly. One pair, two jobs.

Yes. Life+ is a filter, not a full seal. High-frequency signals, including standard alarm tones (typically 2,000 to 4,000 Hz), pass through clearly. You will hear your alarm. You will not hear a partner snoring at 2am or a lorry idling outside. That is exactly what the filter is designed to do.

Each Life+ order includes three sizes: Small, Medium, and Large. If you want a guaranteed fit from the outset, our AR KI TECH service uses AI to analyse two photos of your ears and recommends your precise size before dispatch. Our AR KI TECH customers have a return rate of just 3%, compared to an industry average of 15 to 20%.

Each pair is rated for up to 100 uses. Rinse with warm water after use and allow to air-dry fully before storage. Do not use alcohol-based solutions, as these can degrade the silicone over time. They come with an aluminium travel case for hygienic storage between uses.

If Life+ does not deliver within 40 days of purchase, contact us and we’ll refund you in full. No questions, no process. We offer 40 days rather than the standard 30 because we want you to have genuine time to test them across real shifts and real nights. No financial risk in trying.

Yes. Life+ carries independent certification for its 24 dB noise reduction rating from PZT GmbH, a Notified Body (No. 1974) authorised under EU and UK standards. The design patent is registered in the UK, EU, USA, Canada, Australia, and Japan. It has been featured in BBC Science Focus, Which?, and Wired.
