On this page, you find our selection of BIG SANI filter housings and cartridges that are compatible with each other. Our SANI filters and cartridges are silver treated to create a durable product. We have filters in a variety of sizes and with a filtration level from 1 micron to 100 microns. All our filter housings and cartridges on this page are manufactured by the Italian brand Atlas Filtri, who is one of the biggest and most popular brands on the global market for filters. Please be aware that the filters on this page cannot clean water but the treatment prevents bacterial formation on the surface that is in contact with water. If you are going to filter water, we recommend you looking at our selection of water filters instead.
