Preservative-free products are important for those with sensitivities or allergies to certain chemicals, and they may also be preferable for frequent use to avoid potential side effects from preservatives. While not all Cold & Sinus products are preservative-free, options like the Tivic ClearUP 2.0 offer a completely medication- and preservative-free solution, relying on technology rather than chemicals. Having preservative-free options available ensures that even those with sensitivities can find effective relief.
