Should I have installed Microsoft Office 2010 Filter Pack 64 bit with Ex 2013 SP1?

I have installed Exchange 2013 SP1 on a 2012R2 server, and all went well (I am at early stages of migration).

Following the pre-reqs listed here: https://technet.microsoft.com/en-us/library/bb691354%28v=exchg.150%29.aspx#WS2012

I installed Microsoft Unified Communications Managed API 4.0, Core Runtime 64-bit only.

Since then I have seen other articles suggesting that I install:

Microsoft Office 2010 Filter Pack 64 bit
Microsoft Office 2010 Filter Pack SP1 64 bit

Given I didn't notice any errors in the install, do I need to install those filter packs or is that outdated advice?

regards
