Whirlpool 8171434

The Whirlpool 8171434 replacement large pre-filter uses an activated carbon prefilter to reduce odors found in the air and captures larger particles before they reach your HEPA filter. A prefilter acts to reduce the amount of particles your main filter has to capture. When large particles hit this element, it can be less effective at grabbing the smaller contaminants that cause most issues for allergy sufferers. This both keeps your main filter working longer, but also saves you money by reducing the frequency of filter change outs.
