Replacement Parts for Anjon BioPro™ Pressurized Filters (Current Models ONLY) BP-4000 or BP4000

These replacement UV bulbs and filter sets are for the Bio-Pro™ 3000 & 4000 Pressurized Filters.

Note: these are parts for the current generation of BioPro filters (BP-3000, BP-4000), not the previous generation (BP-1000H, BP-2000H, BP-3000H, BP-4000H). If your filter has a plunger handle on top, these are not the correct parts for your filter.
