Maintain your spa with this Canadian Spa Company Antimicrobial Glacier Filter Set. If your spa requires one or two 50ft² filters, this pack will work for you - the pre-filter screens can be disposed of if not needed. Featuring advanced antimicrobial technology, these filters actively combat and inhibit the growth of bacteria in your hot tub, ensuring a hygienic and healthy spa environment. Crafted with Silver Ion-infused plastic, these filters create a hostile environment for bacteria, preventing their build-up in or around the filter. Also, the fine mesh pre-filter acts as the first line of defence against spa water contaminants, resulting in a less frequent filter replacement schedule. Overall, enjoy cleaner water and thanks to easy-to-clean pleats and the pre-filter, maintenance becomes a breeze. This is a pack of two 50ft² Antimicrobial filters and two pre-filter screens.
