Replacement True HEPA Filter # W4-0840

 
Replacement True HEPA Filter # W4-0840
 
Usually replaced every 2-3 years. The life of this filter depends on the amount of contaminants in the air and the frequency in which the prefilter has been changed. Renovations in the home that create wood or drywall dust or similar contaminants will shorten the life expectancy of the HEPA filter. To improve airflow, the HEPA filter can be vacuumed between changes, preferably outdoors. Use a soft brush attachment for vacuuming this filter.
Note: Handle the HEPA filter by the frame only. The paper is fragile and a puncture or tear will reduce efficiency.
