Product review (5 stars): Thick
Trying these out in a&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Vornado-Evap40-4-Gallon-Evaporative-Humidifier/dp/B00O0WOO74/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Vornado Evap40 4-Gallon Evaporative Humidifier</a>&nbsp;and so far they are working great. They are much thicker then originals and I'm finding it running less to keep the humidity at the sent point.

It does not say if they are coated in anything to prevent growth so only time will tell how long they last. So far for the price they can't be beat.
