How often do the Bio-Guard filters need replacing?

This zero waste approach eliminates ongoing filter costs and reduces environmental impact compared to traditional paper filters that require regular disposal.

What size room can this air purifier effectively clean?

The unit purifies up to 186 cubic metres of air per hour which suits large living spaces, open-plan areas and master bedrooms. For a standard 3-metre ceiling height, this covers approximately 62 square metres of floor space. The powerful motor maintains consistent performance even in larger rooms without compromising filtration quality.

Does this remove pet odours and allergens?

Yes, the four-stage filtration system effectively removes pet hair, dander and associated odours. The Bio-Guard filters capture microscopic allergens whilst the ozone emission removal filter eliminates odour-causing compounds. The 0.1 micron capture rate ensures even the smallest pet allergens are removed from your indoor air.

Can I control this air purifier remotely?

What makes this different from HEPA filter purifiers?

This unit captures particles as small as 0.1 microns compared to HEPA's 0.3 micron standard, providing superior filtration performance. The washable Bio-Guard technology eliminates ongoing filter replacement costs and waste. Additionally, the dedicated ozone emission removal filter actively eliminates harmful ozone rather than just filtering particles.

How do I clean the washable filters properly?

Remove the Bio-Guard filters according to the instruction manual and rinse thoroughly with clean water. Avoid using detergents or chemicals which could damage the filter material. Allow filters to air dry completely before reinstalling to prevent mould growth. The stainless-steel prefilter can also be cleaned with water and dried thoroughly.

Does this help with smoke and chemical fumes?

Yes, the multi-stage filtration specifically targets smoke particles and harmful chemicals. The Bio-Guard filters capture smoke particles whilst the ozone emission removal filter eliminates chemical compounds and toxic ozone. This makes it effective for homes with smokers, cooking odours, cleaning product fumes and outdoor pollution infiltration.
