Setup: Beurer App-controlled Air Purifier LR 400 / LR 401 User Manual

Introduction — beurer App-controlled Air Purifier LR 400/LR 401

The beurer App-controlled Air Purifier LR 400 / LR 401 is a compact, app-enabled air cleaning solution designed for homes and small offices up to 69 m² that combines a three-layer filtration system (pre-filter, activated carbon, HEPA H13) with intelligent sensors and Wi‑Fi/Bluetooth control via the beurer FreshHome app. The LR 400 and LR 401 models offer automatic air-quality detection, four fan speeds plus turbo, a colour-coded ambient air indicator, night mode for near-silent operation, and optional ultraviolet light for additional disinfection capability, making them suitable for allergy sufferers, pet owners, and households seeking improved indoor air quality.

Key benefits and unique selling points include a HEPA H13 stage that captures very fine particles (manufacturer states up to 99.95% efficiency for typical particulate sizes), a CADR of approximately 266 m³/h for fast circulation in mid-sized rooms, intelligent automatic mode that adapts fan speed to measured particulate levels (PM2.5), and remote monitoring and control through the FreshHome app for scheduling and status checks while you're away. Typical use cases cover living rooms, bedrooms, home offices, and shared family spaces where pollen, dust, pet dander, odors and airborne microbes are a concern.

Target audience: allergy and asthma sufferers, parents of young children, pet owners, home office users, and people looking to improve general indoor air quality. Estimated price range (street/retail) for these app-controlled units is generally in the mid-range for consumer HEPA purifiers—expect retail prices to vary by market and retailer; official listings and resellers typically position the LR 400 / LR 401 as a value proposition given its HEPA H13 filtration, smart controls and room coverage. Availability: sold through Beurer’s official channels and major retailers in many regions; replacement filters (model 693.09) and optional UV accessories are available separately.

Connecting the Air Purifier to the “beurer FreshHome” App

You can also use the basic functions of the air purifier without the “beurer FreshHome” app. The additional features, such as recording the ambient air values and setting a cleaning schedule, as well as controlling and monitoring your device when you are on the go, are only available in conjunction with the “beurer FreshHome” app.

1. Ensure that your smartphone is connected to your Wi-Fi network.
2. Activate Bluetooth® on your smartphone.
3. Download the free “beurer FreshHome” app from the Apple App Store (iOS) or Google Play (Android™). Depending on the settings for your smartphone, additional charges may be incurred for connecting to the internet or transferring data.
4. Start the “beurer FreshHome” app and follow the instructions.
5. If you want to use the air purifier without Wi-Fi, briefly press the Wi-Fi button 17. The Wi-Fi display 18 goes out, and Wi-Fi is now switched off. To switch on Wi-Fi again, briefly press the Wi-Fi button 17 again. The Wi-Fi display 18 lights up, and Wi-Fi is now switched on again.

Switching On the Air Purifier

1. Follow the instructions in the “Initial Use” section.
2. Insert the mains plug into a suitable socket. Ensure that the cable does not pose a trip hazard.
3. Press the ON/OFF button 21 to switch on the air purifier. When the air purifier is used for the first time, it starts on the lowest fan speed setting I.
4. The LED light ring 2 switches on automatically. After approximately 30 seconds, the colour of the LED light ring 2 will indicate the current air quality, which corresponds to the concentration of particles in the ambient air around the device.

Selecting the Fan Speed and Mode

The air purifier has a total of four fan speeds (I, II, III, IV) and three modes (TURBO mode, AUTO mode, NIGHT mode).

1. Switch on the air purifier using the ON/OFF button 21.
2. Select your desired fan speed by pressing the fan speed button 10. The fan speed indicator 11 shows the fan speed that is currently set.

UVC Light

The UVC light eliminates germs in the air. When this happens, the UVC light activates titanium oxides that break down foul-smelling odour molecules (caused by tobacco smoke, cooking smells, or animals).

1. To switch on the UVC light, briefly press the UVC/sleep button 12 while the air purifier is switched on. The UVC indicator 13 lights up as soon as the UVC light is active.
2. To switch off the UVC light, briefly press the UVC/sleep button 12 again. The UVC indicator 13 goes out.

Timer Function

The air purifier features a timer function that you can use to determine the number of hours the air purifier should run for before it automatically switches itself off. You can set three different timer times (2, 4, or 8 hours) on the control panel of the air purifier 1.

1. Use the timer button 15 to select your desired timer (2, 4, or 8 hours). The timer that is currently set lights up in the timer indicator 16.
2. To switch off the timer, press the timer button 15 repeatedly until all the LEDs are off in the timer indicator 16.

Cleaning and Maintenance

Warning: Before cleaning, always ensure that the mains plug of the air purifier has been properly disconnected.

Cleaning the Filter

Regular cleaning of the filter 8 (once a month) is required to ensure hygienic and fault-free operation. Clean the outside of the filter with the brush attachment of a vacuum cleaner or a dry cloth.

Cleaning the Housing

Clean the housing of the air purifier with a slightly damp cloth (water or a mild cleaning solution). Do not use solvents, other aggressive cleaning/scrubbing agents, or alcohol, as these could damage the surface.

Cleaning the PM 2.5 Dust Sensor

Regular cleaning of the dust sensor and its associated channel (once a month) is required to ensure fault-free operation. To do this, open the sensor flap 5 on the side of the device. Use a dry cotton bud to remove coarse dust from the open channel. For even better cleaning results, you can now also run the device at the highest setting to clear the loose dust. Close the sensor flap once cleaning is complete..

Storage

If you do not plan to use the device for a long period of time, we recommend that you clean it and store it in the original packaging in a dry environment, ensuring it is not weighed down by additional items.

Troubleshooting

Pros & Cons — Honest assessment of beurer App-controlled Air Purifier LR 400 / LR 401

• Pros — Effective filtration and smart control

  The three-layer filter with HEPA H13 captures a high proportion of fine particles and allergens, while the activated carbon layer helps reduce odors; the device is controllable via the beurer FreshHome app for remote monitoring, scheduling and automatic mode operation

• Pros — Room coverage and CADR

  With a CADR around 266 m³/h and suitability for rooms up to 69 m², the LR 400 / LR 401 handles medium-to-large living spaces more effectively than many compact purifiers in the same price band.

• Pros — Low noise and practical features

  Night mode reduces noise below 30 dB for bedrooms, and the unit includes timer, filter-change indicator and a colour-coded air-quality LED for quick status checks.

• Cons — Ongoing filter cost and maintenance

  Replacement filters (693.09) are sold separately and filters have an estimated lifetime (manufacturer cites ~4,320 operating hours), so owners should budget for recurring filter replacement costs.

• Cons — Optional UV and feature trade-offs

  UV cleaning is optional rather than standard; users seeking built-in UV sterilization must confirm model/configuration and understand UV adds maintenance and safety considerations.

• Cons — Smart setup and dependency on app

  Full functionality requires the beurer FreshHome app (Bluetooth setup, Wi‑Fi control); users who prefer fully manual devices or who avoid connected devices may find this inconvenient.

• Value for money

  Compared with small HEPA-only portable units, the LR 400 / LR 401 offers stronger room coverage, HEPA H13 performance and smart features that make it a competitive mid-range choice; compared to premium whole-room systems it is more affordable but lacks some advanced sensors or integrated HVAC compatibility.

Customer Reviews & Real-user Feedback for beurer App-controlled Air Purifier LR 400 / LR 401
