The Beurer LR 300 is a three-stage air purifier that Beurer’s 2018 specification sheet rates for rooms up to 35 m². It offers automatic operation, three fan levels, a timer and optional UV light, but the published material available here does not establish a CADR, measured noise level or independent real-world performance. The filter details also vary between Beurer’s older sheet and later materials, so check the model and replacement part carefully before buying.
What the Beurer LR 300 offers
Beurer’s 2018 specification sheet describes the LR 300 as using a pre-filter, activated-carbon filter and EPA filter. It lists automatic mode, three fan levels, a timer, optional UV light, an illuminated panel and a filter-change indicator. The same sheet gives dimensions of 14.5 × 38.8 × 42.8 cm, an approximate weight of 4.5 kg and rated power of 55 W. These are manufacturer specifications from a sheet dated April 5, 2018; regional or later versions may differ. Beurer LR 300 data sheet
How large a room is it suitable for?
Beurer’s 2018 sheet says “For rooms up to 35 m2.” Treat that as the manufacturer’s stated room suitability, not an independently verified cleaning rate. The sheet does not provide a clean-air delivery rate (CADR), air changes per hour or a test method that would let you compare room-cleaning speed with other purifiers. Room suitability alone cannot establish how quickly the unit will reduce particles in a particular space.

Beurer’s documents use different filter terminology and particle-removal figures. The 2018 LR 300 sheet describes an EPA filter and says 99.5% of particles such as bacteria, viruses, fine dust and pollen can be filtered out. Beurer’s 2022 catalogue instead describes the LR 300/310 filter set as pre-filter, activated-carbon filter and HEPA H13 filter, and states 99.95% filter performance. The sources do not explain whether those percentages use the same test conditions, so they should not be combined or treated as independently verified outcomes. Neither figure establishes protection against illness. Beurer 2022 catalogue

Replacement filter compatibility
Beurer’s current replacement listing identifies article 69302, EAN 4211125693022, as a HEPA H13 plus activated-carbon combi filter compatible with the LR 300 and LR 310. Confirm that the model and part number match your unit before ordering. The listing identifies the part; it does not establish retail stock or price. Beurer LR 300/310 replacement filter
How often should you replace the filter?
Beurer’s 2018 sheet gives an approximate filter runtime of 4,320 operating hours, and the available manual copy says to replace it after that number of operating hours. This is a usage-hours figure, not a guaranteed calendar interval: actual elapsed time depends on how long the purifier runs. The sheet lists a filter-change indicator, which can also help signal maintenance.

Replacing the filter and resetting the counter
The available manual copy, hosted by Winnings Electronics, gives this sequence. Check the regional manual supplied with your unit if its controls or instructions differ. LR 300 manual copy
- Turn off and unplug the purifier.
- Remove the cover and filters, then replace the combi filter.
- Reinstall the pre-filter and cover, then reconnect power.
- Hold the AUTO button for five seconds to reset the operating-hours counter.
What is not established by the published specifications?
The available Beurer material does not provide a CADR, noise measurements by fan level, power consumption by speed, or independent test results for particle removal and room-cleaning speed. The 2018 sheet calls operation quiet, but that is a manufacturer description rather than a measured sound level. These gaps matter when comparing this model with alternatives: look for independently tested CADR under a stated method, sound levels by setting, filter replacement cost and availability, and warranty terms for your region.

Who should consider the Beurer LR 300?
The LR 300 may suit someone who wants a purifier with automatic operation, multiple fan settings, a timer and a stated maximum room area of 35 m², and who can confirm compatible replacement filters are available for their model. It is harder to assess against other units if you need comparable test data on cleaning speed, noise or operating cost, because those figures are not given in the cited specifications. Verify the replacement-filter designation and consult your unit’s regional manual before maintenance.
