Description
The Lite Air Filter provides advanced protection against harmful particles in the air. The multi-layer filter technology is tested at the Research Institutes of Sweden (RISE) with results showing 98% filtering efficiency against particles down to 0.3μm in size. The filter is available in 4 sizes and each filter pack contains 3 replaceable filters.
How long does a filter last?
The filter lifetime depends on many factors such as the pollution in your surroundings. Our filters last for about 1 month of usage, but we advise to change every second week for hygienic reasons.
