Submerge Ice Bath 7.7" x 4.5" 20 Micron Replacement Filter (4-Pack) — Pleated Sediment, Protects Pump

Submerge Ice Bath’s 7.7" x 4.5" 20 micron replacement filter (4-pack) is a pleated sediment filter engineered to trap fine particles, protect your cold plunge pump, and keep plunge water clearer between treatments.

Maintaining clean water in a cold plunge or ice bath is essential for performance and equipment longevity. These individually wrapped filters are sized to fit all standard 7.7" cold plunge chillers and are built to remove sediment, rust, dirt, and oils down to 20 microns. The pleated design increases surface area for better flow and longer life, while the universal sizing simplifies replacement so you can spend less time on maintenance and more time plunging.

How does this filter improve cold plunge water clarity?

The 20 micron pleated media captures fine particles that typical coarse filters miss, resulting in visibly cleaner water and fewer suspended solids. Removing sediment and oils reduces cloudiness and helps maintain chemical balance in systems that use sanitizers.

• 20 micron rating removes rust, dirt, silt and bodily oils
• Pleated construction increases filtering surface for higher capacity
• Reduces visible cloudiness between full water changes

Will these filters protect my chiller pump and system?

Yes — using correctly sized, industry-appropriate filters reduces debris reaching the pump and heat-exchange surfaces, lowering strain on the unit. That protection helps avoid clogs and overheating that can shorten component life or trigger warranty issues.

• Specifically sized for 7.7" chillers to ensure proper flow and fit
• Prevents large and fine debris from entering pump and plumbing
• Helps maintain consistent water flow and cooling efficiency

How easy is installation and routine replacement?

Installation is straightforward: each filter comes individually wrapped for hygiene — simply unwrap, rinse or soak as instructed, and insert into your filter housing. Replacements are quick and portable, sold in a four-pack so you can rotate spares without downtime.

• Comes in a 4-pack for staggered replacements
• Individually wrapped to keep filters clean until use
• Simple drop-in fit for standard 7.7" x 4.5" housings

Can I use these filters in other systems besides cold plunges?

Yes — the 20 micron pleated design is versatile and compatible with a variety of small-scale water systems. These filters work well in ice pods, hot tubs, pools, and inline sediment filter housings where a 7.7" x 4.5" cartridge and 20 micron rating are appropriate.

• Suitable for ice baths, plunge pools, spa systems and inline housings
• Helps standardize maintenance across different units and locations
• Ideal when fine sediment removal is required without heavy chemical use
