TheraFrost Cold Plunge Replacement Filters (3-Pack)

This 3-pack of replacement filters for the TheraFrost Cold Plunge keeps your plunge water clean and clear, capturing impurities as the water circulates so every session feels as inviting as your first. Fresh filters are the simplest way to protect both your water quality and the long-term performance of your system.

Cold exposure works best as a habit, and a habit needs water you actually want to get into. Set a reminder, swap in a fresh filter every 1 to 2 months, and keep the spares nearby so your TheraFrost is always ready when you are.
