Marreal AP3001B HEPA Air Purifier (White, 60m² Coverage)

What room size does the Marreal AP3001B effectively cover?

This air purifier is designed for rooms up to 60m². The coverage area depends on ceiling height and air quality conditions, but it performs optimally in standard residential rooms of this size. For larger spaces, you may need multiple units or a higher capacity model to achieve the same level of air cleaning effectiveness.

How often do the HEPA filters need replacing?

Filter replacement depends on usage and air quality conditions. The built-in filter change indicator will illuminate when replacement is needed, typically after 6-12 months of regular use. Heavy usage of 16-24 hours daily may require more frequent changes. Replacement filters are readily available and easy to install using the simple twist-lock mechanism.

Is the ioniser safe for indoor use and does it produce ozone?

Yes, the ioniser is designed to be safe for continuous indoor use. It produces less than 0.04ppm ozone, which is considered ozone-free by safety standards. The negative ions help neutralise airborne particles and freshen the air without creating harmful ozone levels. The ioniser is wear-free and requires no maintenance or replacement.

Can I use this air purifier in the bedroom at night?

Absolutely. The ultra-quiet operation makes it ideal for bedroom use. On the lowest setting, it produces minimal noise - just a gentle whisper that's less disruptive than outdoor sounds through an open window. The night mode dims the LED displays, though they cannot be completely turned off. Many users report better sleep quality, especially those with allergies.

What maintenance does this air purifier require?

Maintenance is minimal. The pre-filter should be vacuumed every 2-3 months to remove larger particles and extend HEPA filter life. The main HEPA filter needs replacing when the indicator light activates. The UV-C lamps and ioniser are designed to be maintenance-free. The exterior can be wiped clean with a damp cloth as needed.

Does the automatic mode actually work effectively?

Yes, the automatic mode uses a sensitive particle sensor that responds quickly to changes in air quality. When it detects increased particles from cooking, cleaning, or outdoor pollution, it automatically increases fan speed. Once air quality improves, it reduces speed to maintain optimal conditions while minimising noise and energy consumption.

What types of pollutants does this air purifier remove?

The multi-stage filtration system removes a wide range of pollutants including pollen, dust mites, pet dander, bacteria, viruses, mould spores and smoke particles. The activated carbon filter tackles chemical fumes and odours. The UV-C light provides additional sterilisation, while the HEPA filter captures 99.97% of particles down to 0.3 microns in size.

How much does it cost to run this air purifier continuously?

Running costs are very low due to efficient LED and motor technology. On the lowest setting, it consumes just 3-4 watts - similar to a small LED bulb. With all features active including UV-C and ioniser, consumption reaches 8-9 watts. At current UK electricity rates, continuous operation costs approximately £15-25 per year, making it economical for 24/7 use.
