Beurer LR 310 Air Purifier with HEPA Filter

The Beurer LR 310 Air Purifier with HEPA Filter draws room air through a three-layer filter system to reduce airborne particles like domestic dust, pet hair, pollen, fine dust and odours. It's designed for rooms from 18 m² up to 54 m², which makes it a practical option for a nursery, bedroom or open-plan living space where you want cleaner air without constantly adjusting settings yourself.

If someone in the home is sensitive to pet hair, dust, dust mites or pollen, this is where an air purifier earns its place. The LR 310 pairs a HEPA H13 filter with an automatic air-quality sensor, so it monitors the room and adjusts on its own rather than relying on you to notice when the air feels stuffy. It's an approved medical device with regulatory certification from both the European Union and South Africa (SAHPRA).

Three-layer filtration with HEPA H13

Air passes through a prefilter, an activated carbon filter and a HEPA H13 filter in sequence. The prefilter catches larger debris, the activated carbon layer helps with odours, and the HEPA H13 filter handles the fine particles. Tests show the three-layer system filters out at least 95% of particles as small as 0.02 microns (viruses are generally 0.02–0.3 microns in size), and for particles 0.3 microns in size the filter performance reaches up to 99.95%. There is also an optional ultraviolet light for additional cleaning.

How it Works

• Three-layer filter system: A prefilter, activated carbon filter and HEPA H13 filter work in stages to capture progressively finer particles and help reduce odours.
• Automatic air-quality monitoring: A sensitive sensor detects fine dust particles up to 2.5 microns in size and the device adjusts itself based on the level of fine dust pollution, so it responds to the room without manual input.
• Clean Air Delivery Rate: The CADR is approximately 200 m³/h — a measure of filtered air output under stated test conditions rather than a health outcome.
• Optional UV light: An ultraviolet light can be switched on for additional cleaning alongside the filters.

Everyday use and settings

You get three power levels and a timer you can set to 2, 4 or 8 hours. Noise scales with the setting — approximately 30 dB on level 1, 46 dB on level 2 and 56 dB on level 3 — so the lowest setting suits a quiet sleep environment. A safety automatic switch-off function is built in, and the high-quality filter has a running time of approximately 4 320 operating hours, with a filter change indicator that flashes on the control panel when it's time to replace it. The unit draws 50 watts, measures 14.5 x 38.8 x 42.8 cm and weighs roughly 4.5 kg.

Maintenance

Regular cleaning keeps the LR 310 working reliably. Clean the three-layer filter about once a month using the brush attachment of a vacuum cleaner, or carry out a more thorough clean as set out in the instruction manual. The fine dust particle sensor should be cleaned every two months, or more often in a dusty environment. Replacement filters are available (Beurer Replacement Filter Set for Air Purifier LR 300 and LR 310), so you can keep it running well over time. It carries a 3-year limited warranty.

Best For

The Beurer LR 310 Air Purifier is a great option for parents who:

• Want to reduce airborne dust, pet hair, pollen and fine dust in rooms up to 54 m²
• Have a household member sensitive to pet hair, dust, dust mites or pollen
• Prefer a purifier that monitors air quality and adjusts automatically
• Value a quiet low setting for use in a bedroom or nursery at night

It may not be the best fit if you:

• Need to cover a space larger than 54 m²
• Are looking for a humidifier or diffuser rather than particle filtration
