The Braun LF40 Lens Filter is a box of 40 disposable probe covers (Hygiene caps) for Braun ThermoScan ear thermometers. Fitting a fresh lens filter over the temperature sensor before each reading keeps the sensor window clean, which is a simple but important part of getting a reliable measurement from your ear thermometer.
Designed for use with all Braun ThermoScan models, these replacement lens covers are latex- and BPA-free. Because they're single-use, they help to avoid cross-contamination when you're taking readings across more than one family member — a practical consideration in a busy household.
Why the lens filter matters
On a tympanic (ear) thermometer, the reading depends on a clear path between the sensor and the ear. Over time, dirt or ear wax can build up on the sensor window and clog it, which can lead to inaccurate temperature readings. Fitting a new Braun Hygiene cap each time helps keep that sensor window clean, so each measurement starts from a fresh, hygienic surface.
How to use
- Fit a new Braun Hygiene cap onto the probe before each measurement.
- Take the reading following your ThermoScan's own instructions.
- Remove and discard the used cap after the reading.
Best For
The Braun LF40 Lens Filter is a great option for parents who:
- Already use a Braun ThermoScan ear thermometer and need replacement probe covers
- Take temperatures across more than one person and want a single-use cap for each reading
- Want to keep the sensor window clean to support consistent readings

Always follow the instructions supplied with your Braun ThermoScan thermometer for correct measurement technique. A thermometer reading should be considered alongside your child's age and overall condition, and very young infants or a child who seems unwell need prompt clinical assessment regardless of the number.
