The Beurer LR 300 is specified for rooms up to 35 m² and offers automatic operation, three fan levels, a timer and optional UV light. Those are manufacturer specifications, not independent proof of how quickly it cleans a room: Beurer’s 2018 sheet gives no CADR value, and no independent test of the LR 300’s cleaning speed, noise or energy use is established here. Its filter identity also needs a little care: Beurer’s older sheet says “EPA,” while later Beurer material identifies a HEPA H13 replacement set.
What the Beurer LR 300 offers
Beurer’s English data sheet, dated 5 April 2018, describes a three-layer filtration arrangement: a pre-filter, an activated-carbon filter and an EPA filter. It lists automatic mode, three fan levels, a timer, optional UV light, an illuminated panel and a filter-change indicator. The sheet also calls its operation “quiet,” but does not provide a sound level to quantify that description. Beurer LR 300 data sheet (2018)

How large a room is it suitable for?
Beurer’s 2018 sheet says the LR 300 is “For rooms up to 35 m2.” Treat that as the manufacturer’s room-suitability guidance, not as an independently verified coverage result. The sheet does not state a clean-air delivery rate (CADR), air changes per hour, or the assumptions behind the room-size figure. Room area alone therefore cannot tell you how quickly the purifier will reduce airborne particles in your particular space.

The 2018 LR 300 sheet says that “99,5% of the particles” can be filtered out, naming bacteria, viruses, fine dust and pollen as examples. This is a manufacturer claim in that dated product document, not an independently verified result or evidence of protection against disease. The sheet does not state the test conditions needed to interpret the percentage as real-world performance.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.

- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
There is a later, different figure: Beurer’s 2022 catalogue gives 99.95% filter performance for the LR 300/310 filter set. The catalogue does not explain how that figure relates to the 99.5% in the 2018 LR 300 sheet or establish that the two figures use the same test conditions. They should not be combined or treated as interchangeable. Beurer 2022 catalogue, air purifiers and filters
Which replacement filter fits the LR 300?
Beurer’s current replacement-filter listing identifies article 69302, EAN 4211125693022, as compatible with both the LR 300 and LR 310. The listing describes it as a HEPA H13 plus activated-carbon combi filter. Beurer’s 2022 catalogue describes the LR 300/310 set as a pre-filter, activated-carbon filter and HEPA H13 filter. That differs in terminology from the 2018 LR 300 sheet, which calls its third layer an EPA filter; the available documents do not explain the wording change. Check the exact model and regional instructions before ordering. Beurer LR 300/310 replacement filter, article 69302

Filter life and replacement reset
Beurer’s 2018 sheet lists an approximate filter runtime of 4,320 operating hours. The figure refers to hours of operation, not a guaranteed calendar interval: the time to reach it depends on how long the purifier runs. The sheet also lists a filter-change indicator.

Power, size and weight
The 2018 Beurer sheet lists rated power of 55 W, dimensions of 14.5 × 38.8 × 42.8 cm and approximate weight of 4.5 kg. These are figures from that dated manufacturer sheet; it does not provide power use by fan level. Nor does the available evidence establish a current retail price, replacement-filter price or stock status.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Who should consider the LR 300?
The LR 300 may suit someone looking for the listed controls and filtration features in a purifier Beurer rates for rooms up to 35 m², provided they can source the compatible replacement filter. But the available specifications are not enough to judge its cleaning speed, noise at each fan level or efficiency against another purifier. For that comparison, look for independently measured CADR under a stated test method, noise measurements, power use by speed and replacement-filter cost and availability. Those figures are not established in the cited LR 300 material.
