If you are paying your loan installments using your CPF money
then HPS is mandatory for you first. After you have HPS coverage, you can apply for exemption using other life insurance policies.
Beginning from this year, HPS premium rate has been reduced, on average about 12% lower than before. Furthermore, HPS premium is paid using your CPF money.
However, if you are still looking for private life insurance to cover your loan protection, you may consider term policy, mortgage reducing term policy, or other life policies instead.
