Depending on the degree of environmental pollution and usage, we recommend replacing it every 3-6 months. The pre-filter captures large particles like hair and fiber and can be cleaned with a vacuum cleaner every 2-4 weeks to maintain its effect. The HEPA and carbon filters cannot be cleaned. If the filter has begun to emit peculiar smell, please replace it with a new filter immediately. The replacement filters can be purchased in our store.

The JF260 and JF999 air purifier can monitor air quality by displaying PM2.5 number at front screen.

Yes it has the standard filter in it. Just have to open the unit and take off the plastic bag around the filter.

The outer pre-filter should be cleaned every 2–4 weeks to increase efficiency and extend the life of your filter. Clean the pre-filter using a soft brush or vacuum hose to remove hair, dust, and large particles. Do not clean the filter with water or other liquids. We hope this helps!
