How avoid sinus problems when swimming?

Want to exercise swim in YMCA pool

Have goggles to wear to protect eyes but invariably get
water up the nose and sinus problems later that day

Would getting nose clips help? If yes...any brand work
or are there some brands/models superior for a male
adult?

Or..what abt swim masks that cover the nose as well as
eyes thereby not allowing any water into nose that way?
