How do the benefits differ? What would you owe in out-of-pocket costs if you were to be injured or get seriously ill? How does that compare with your out-of-pocket exposure on the employer-sponsored plan? Are your doctors in the network of the individual plan? You'll want to carefully consider all of these things before switching, and keep in mind that you won't be able to rejoin your employer's plan until the next open enrollment window offered by your employer.
A good place to start is HealthCare.gov. This is the health insurance exchange created by the The Patient Protection and Affordable Care Act, and is a one-stop shop for private individual market health insurance plans (note that the exchange itself is run by the government, but the health plans for sale in the exchange are all private, from the health insurance companies with which you're already familiar). People in 39 states use HealthCare.gov to enroll in individual market plans. The other 11 states and the District of Columbia have state-run exchanges, and you'll be directed to their sites from HealthCare.gov when you select your state.
There are other online brokerages, both large and small, that can help you sort out the individual market health insurance options available in your area. Most of them can show you plans that are available in the exchange as well as options that are only available outside the exchange (no subsidies are available outside the exchange, but as noted above, you're probably not eligible for subsidies anyway, if you have access to an employer-sponsored plan).

But it's also worth noting that if they keep the employer-sponsored plan for the whole family, the premiums will almost certainly be payroll deducted on the pre-tax basis. On the other hand, if they opt to buy an individual market plan, the premiums would only be tax deductible to the extent that they (along with other medical expenses) exceed 10 percent of the family's household income, and assuming that the family opts to itemize their tax deductions (increasingly rare now that the Tax Cuts and Jobs Act has greatly increased the standard deduction).
Individual and family health insurance plans can help cover expenses in the case of serious medical emergencies, and help you and your family stay on top of preventative health-care services. Having health insurance coverage can save you money on doctor's visits, prescriptions drugs, preventative care and other health-care services. Typical health insurance plans for individuals include costs such as a monthly premium, annual deductible, copayments, and coinsurance.
