Replaceable filters are used in the purifier. You need to clean or replace the filters
after long-term use to
ensure a better purification effect.
Pre-Filter

Replace the pre-filter when more than 70% of its surface is covered by dust that can't be removed.
HEPA Filter
Replace After Use For 3-6 Months
Replace the HEPA filter when it fails to filter out smoke.
Main Filter
Replace After Use For 2-3 Months
Clean the medium filter when the dust on it causes poor suction of the purifier. If you cannot clean the dust thoroughly, please replace the medium filter.
