Quats are bactericidal, fungicidal, and virucidal toward lipophilic viruses. They are not sporicidal, tuberculocidal, or virucidal toward hydrophilic viruses. They are used to sanitize noncritical sur-faces like walls and furniture. Most ventilator tubing is disposable and is therefore not cleaned and disinfected.
