Bullfrog Simplicity™ Flat Filters for M Series (4 Pack)
Bullfrog Simplicity™ Flat Filters are the genuine replacement filters for Bullfrog's newest spas — and they represent a real rethink of how a spa filter is built. Instead of a pleated cartridge wrapped around a plastic core, the Simplicity filter is a flat, plastic-free panel that puts 100% of its surface to work. Sold here as a 4-pack, this is everything you need to keep a Simplicity-equipped spa filtering cleanly for months.
Your spa filter is the hardest-working component in your water care system. Every gallon passes through it again and again, trapping body oils, lotions, dead skin, pollen, dust, and the fine particulate that would otherwise cloud your water and clog your jets. A clean filter is what lets your sanitizer do its job instead of fighting a losing battle against debris — and a tired or clogged filter is the quiet cause behind a lot of cloudy-water and high-chemical-demand headaches.
The Simplicity design solves the two biggest annoyances of traditional filters. First, a conventional cylindrical cartridge wastes media: the round shape and rigid center core mean a lot of the filter isn't actually doing much filtering. The flat Simplicity panel uses its entire media area. Second, the Simplicity filter is built to be genuinely low-maintenance — rinse it with a garden hose when it's convenient, or skip the cleaning entirely and just swap in a fresh one each month. The 4-pack is sized to make that monthly rhythm easy.
