The Cyclo UV air purifier filters the air in 3 stages: prefilter, activated carbon filter and finally, using a
high performance HEPA-H13 filter.
The replacement time or life time of the filter will vary based upon hours of use. The filter is suggested to be replaced once a year or every 1,000 hours of use. The Cyclo-UV air purifier “filter icon” will blink at 1,000 hours. after the filter is changed, the reset button will need to be pressed to start your next 1,000 hours of use.
