The Beurer LR 310 is a three-layer air purifier with a pre-filter, activated-carbon layer and HEPA H13 filter. Beurer rates it at about 200 m³/h CADR and says it is suitable for rooms up to about 54 m², but those are manufacturer figures—not independently verified results for every room. Its most useful buying detail is that replacement filter set 69302 is listed for both the LR 300 and LR 310.
What the Beurer LR 310 offers
The LR 310 combines a pre-filter, activated carbon and a HEPA H13 filter. Beurer also lists an optional UV light function and automatic mode, which adjusts fan speed to ambient air quality. In Beurer’s 17 August 2021 press release, the company says: “The LR 310 automatically adapts the fan speed to the ambient air quality.” Beurer’s press release
Its dimensions are 14.5 × 38.8 × 42.8 cm and its listed weight is approximately 4.5 kg. These are manufacturer-published specifications rather than independent measurements. Beurer’s 2022 product data sheet

Beurer’s 2022 product data sheet states approximately 200 m³/h CADR and suitability for rooms up to approximately 54 m², citing the NRCC-54013-2011 convention. The 54 m² figure is a manufacturer-stated maximum, not a guarantee of a particular air-change rate or equivalent cleaning in rooms of every layout, ceiling height or use pattern.

Beurer also reports 99.95% filtration performance. Its 17 August 2021 press release describes an IUTA test conducted in April 2020 under DIN 71460-1: it reports up to 95% filtration for particles at least 0.02 μm and 99.95% elimination for particles at least 0.3 μm. These are Beurer’s reported filter-test results; they do not establish independently measured whole-room performance of the complete appliance in all settings. Beurer’s test description
The cited material does not establish a current, methodologically transparent independent comparative trial of the LR 310. Treat the CADR, coverage and filtration figures as claims or specifications from Beurer, not as a third-party head-to-head verdict.

Will it suit your room and routine?
Use the stated room area as a first screening point, not as a promise. Consider whether the fan speed needed for your space will be tolerable, and whether replacement filters are available at a cost you accept. Beurer lists sound levels of approximately 30 dB at level 1, 46 dB at level 2 and 56 dB at level 3; the product sheet does not establish what level will be necessary in a particular room.
Automatic adjustment may be useful if you do not want to choose fan speed manually. The optional UV function is another feature to consider if it matters to you, but the published material cited here does not establish a separate real-world benefit from using it.

Which replacement filter fits the LR 310?
Beurer lists replacement filter set 69302 (EAN 4211125693022) as a HEPA H13 and activated-carbon combination compatible with the LR 300 and LR 310. Check the model name and article number before buying, especially when a marketplace listing uses a generic compatibility label. Beurer’s replacement-filter page
How often does the filter need replacing?
Beurer’s 2022 data sheet estimates filter running time at approximately 4,320 hours and says the purifier has a filter-change indicator. The hours are an estimate, not a guaranteed service life: actual replacement timing may vary with use and air conditions. Follow the indicator and the current model instructions rather than treating the estimate as a fixed calendar interval. Beurer’s product data sheet

Power and noise specifications
Beurer’s published power figures are not consistent across the cited documents: the product data sheet lists 55 W, while the company’s 2024 catalogue gives approximately 50 W. Check current regional documentation if power consumption is important; neither figure should be presented as a universal value without that qualification. 2022 product data sheet · 2024 Beurer catalogue
The data sheet’s approximate noise figures are 30 dB at level 1, 46 dB at level 2 and 56 dB at level 3. They are manufacturer-listed figures, not measurements made for this review.

Verdict: a feature set with key buying checks
The LR 310 is a plausible option if its stated room coverage, automatic mode and optional UV function match your priorities, and you are comfortable with the specified noise levels and ongoing filter replacement. The strongest practical ownership detail is clear compatibility for Beurer filter set 69302. The evidence here supports describing the manufacturer’s specifications and claims, but not calling the purifier independently proven or ranking it against models tested on a comparable basis.
