New filter
After 3 months at location A
After 2 months at location B.
A Breathe Carbon pre-filter may be used for 2-3 months long in a common situation. But, in a new house, the filter often get the same result much quicker, around 1.5-2 months. If you are using a conventional air purifier, it has no ability to detect it and even send us an alert so we may still be in 50% risk. An intelligent air purifier, which can be personalised and work depending on individual situation, can monitor our situation and keep un informed, therefore, is able to keep the risk very low.
