Product review (5 stars): Perfect Replacement at a Great Price
Having well water with a high mineral content we cannot use the ultrasonic humidifiers (too much white 'dust'). Being that we have to use the cool evaporative models, finding replacement filters for earlier models isn't easy. And if you can even find the original filters, most sellers want and arm and a leg for them. We found these replacements for our older ProCare and Relion humidifiers and they are just like the originals, only MUCH less expensive. So glad to be able to keep our older humidifiers and, with these new filters, be assured of clean humidified air.
