Product Overview
Beckacher’s 120PET flat filters are designed specifically for Bullfrog hot tubs, offering a high‑performance filtration solution that surpasses standard paper filters. Constructed from a proprietary 120PET fabric, each filter provides a uniform weave that captures fine particles while maintaining low back‑pressure, ensuring your spa circulates water efficiently. The flat‑panel design fits seamlessly into the cartridge housing of M Series, A Series, and Swim Series models, reducing the need for additional adapters or modifications. With dimensions of 10.98 x 9.21 x 5.12 inches and a weight of just over 3 pounds per filter, the set is lightweight yet durable, making installation and removal straightforward for both DIY enthusiasts and professional service technicians.
Each pack contains four filters, delivering extended service life and reducing the frequency of replacements. The filters are engineered to handle the high‑temperature environment of hot tubs, resisting degradation from chlorine, bromine, and other common sanitizers. This resilience translates into consistent water clarity, lower maintenance costs, and a more enjoyable spa experience for users. The product carries a strong track record, reflected in a 4.6‑star rating from 24 verified customer reviews, and holds a respectable position in Amazon’s best‑seller rankings for cartridge pool filters.

Usage
These flat filters are ideal for residential hot tubs, small commercial spas, and therapeutic pools that rely on Bullfrog’s filtration system. Whether you are replacing a worn‑out filter or upgrading to a higher‑efficiency option, the 120PET material ensures that even the smallest debris is trapped, preventing cloudiness and protecting the pump and heater from premature wear. The filters perform optimally in a range of water conditions, from fresh‑filled tubs to heavily used facilities, making them a versatile choice for families, fitness centers, and hospitality venues.
Installation is simple: remove the existing cartridge, insert the flat filter into the housing, and re‑secure the cartridge according to the manufacturer’s guidelines. The low back‑pressure design means the pump does not have to work harder, which can extend the life of the pump motor and reduce energy consumption. Regular cleaning of the filter surface with a gentle hose spray will maintain performance, and the durable PET fabric can withstand multiple cleaning cycles without tearing.
