Rowenta XD6085 NanoCaptur (Black, Formaldehyde Filter)

How does NanoCaptur technology differ from regular air filters?

Regular filters trap particles and gases but cannot destroy them. NanoCaptur technology actually breaks down formaldehyde molecules at the molecular level, permanently eliminating them from your air. This prevents re-release of harmful compounds and provides superior long-term protection compared to standard HEPA or carbon filters.

What sources of formaldehyde does this filter target?

The filter removes formaldehyde from cleaning products, pressed wood furniture, building materials, insulation, scented candles and adhesives. These sources are present in 100% of homes according to research. The filter specifically targets this carcinogenic gas that causes respiratory irritation and worsens allergic asthma symptoms.

How do I know when to replace the filter?

The filter contains yellow granules that change colour as they work. When saturated, the granules turn red, indicating replacement time. As more formaldehyde is destroyed, they turn brown. This visual system eliminates guesswork and ensures you replace the filter at the optimal time for continuous protection.

Which Rowenta purifier models are compatible with this filter?

This XD6085 filter is designed specifically for the Rowenta PU4020 Intense Pure Air purifier. The precise dimensions of 18.03 x 16.51 x 1.52 cm ensure perfect fit and optimal performance. Using it with other models may result in poor fit, air leakage and reduced effectiveness.

What room size does this filter effectively cover?

When used with the compatible PU4020 purifier, this filter effectively covers rooms up to 400 square feet. This makes it suitable for bedrooms, living rooms, offices and similar spaces. Larger rooms may require multiple units or a higher-capacity system for optimal formaldehyde removal.

Is formaldehyde really that dangerous in homes?

Yes, the World Health Organisation considers formaldehyde the most dangerous home pollutant and classifies it as a human carcinogen. It causes respiratory irritation, sensitisation and aggravates allergic asthma symptoms. Since it's present in 100% of homes through common products and materials, targeted removal is essential for health protection.

How long does the filter typically last?

Filter lifespan depends on formaldehyde levels in your home, which vary based on furniture, cleaning products and building materials present. The visual indicator system shows exactly when replacement is needed rather than relying on time estimates. Homes with more pressed wood furniture or frequent cleaning product use may require more frequent changes.

Can this filter remove other air pollutants besides formaldehyde?

This filter is specifically engineered for formaldehyde destruction using NanoCaptur technology. While it may capture some other particles due to its physical structure, its primary function is formaldehyde elimination. For comprehensive air purification including dust, pollen and other gases, you'll need additional filtration stages in your purifier system.
