Product review (5 stars): WF1 Kaz filters
The filters were just a little different than what I had been previously been able to buy from the store.  This filter is no longer available retail in my area.  The filter is all in one piece and fits pefectly and funcions perfectly.  I can continue to use my QUIET Kaz Humidifier rather than replace it with a costlier, noisier model with costlier filters.<a data-hook="product-link-linked" class="a-link-normal" href="/WF1-Kaz-Humidifier-Replacement-Filter/dp/B0009H6094/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">WF1 Kaz Humidifier Replacement Filter</a>
