Beurer LR 310 Air Purifier (White, HEPA H13)

What room size is the LR 310 suitable for?

The LR 310 is designed for rooms between 18m² and 54m². For optimal performance in larger rooms up to 54m², run the unit on higher power settings initially. In smaller rooms around 18-27m², the unit can maintain air quality on lower, quieter settings. The 55-watt motor provides sufficient airflow to handle these room sizes effectively, processing the air multiple times per hour.

How often do I need to replace the filters?

The combination HEPA H13 and activated carbon filter lasts approximately 4320 operating hours. This translates to roughly 6 months of continuous 24/7 operation, or 12-18 months with typical 8-12 hour daily use. The filter change indicator on the control panel flashes when replacement is needed, so you don't need to track usage manually. Pre-filters may need more frequent cleaning or replacement depending on air quality conditions.

How effective is it against viruses and bacteria?

Testing by IUTA in April 2020 according to DIN 71460-1 shows the LR 310 filters particles ≥ 0.02 micrometers by up to 95%. Since viruses typically measure 0.02-0.3 micrometers according to health authorities, this makes it highly effective against airborne viruses. The UV-C light technology inside provides additional germicidal action, whilst the HEPA H13 filter captures 99.95% of particles ≥ 0.3 micrometers, including bacteria and larger viral particles.

Is the LR 310 suitable for people with allergies?

Yes, the LR 310 is specifically designed for allergy sufferers. The HEPA H13 filter captures pollen, dust mites, pet dander and other common allergens with 99.95% efficiency for particles ≥ 0.3 micrometers. The activated carbon layer removes odours and gases that can trigger sensitivities. The automatic sensor detects fine particles including pollen and adjusts operation accordingly, providing consistent relief from airborne allergens.

How loud is the air purifier during operation?

Noise levels vary by power setting. Sleep mode operates very quietly, suitable for bedrooms without disturbing rest. Medium power produces a quiet, monotone sound that's comfortable for living areas. High power generates higher noise levels but is typically only used temporarily when heavy purification is needed. The unit automatically adjusts to lower, quieter settings once air quality improves, minimising noise disruption.

Does it remove cooking odours and cigarette smoke?

Yes, the activated carbon filter effectively neutralises odours including cooking smells and tobacco smoke. In testing, kitchen odours in a 50m² room were eliminated within 15 minutes. The combination of activated carbon absorption and high airflow rates ensures rapid odour removal. For persistent odours like cigarette smoke, run on higher power initially, then maintain on medium setting for ongoing odour control.

What is the ion function and should I use it?

The switchable ion function releases negative ions that bind to airborne particles, making them heavier so they're more easily captured by the filter or settle out of the air. This enhances the purification process beyond mechanical filtration alone. You can enable or disable this function based on preference. Some people prefer not to use ionisers in bedrooms, whilst others find the enhanced purification beneficial throughout the home.

How much electricity does the LR 310 consume?

The LR 310 consumes approximately 55 watts at maximum power, similar to a bright LED light bulb. On lower settings, power consumption is significantly less. Running continuously on medium power would cost roughly £10-15 per month based on average UK electricity rates. The timer function helps reduce energy consumption by allowing scheduled operation rather than continuous running, making it economical for regular use.
