How do I set up my microfilters?


What's a microfilter?

A microfilter is a small white box that allows you to use your broadband and any devices that use your phone line, such as a landline phone or Sky box, at the same time.

Your NOW TV Hub comes with two microfilters - one master microfilter, and one standard microfilter.

Got a phone socket with two ports?

If you have a pre-filtered phone socket with two different ports, you don't need to use a microfilter.

If you have one, make sure you use your pre-filtered phone socket to connect your NOW TV Hub – it won’t work with any other socket.

A pre-filtered phone socket

If you don’t have a pre-filtered phone socket with two ports and your microfilters aren't set up correctly, you might experience:

  • Slow internet speed
  • An unreliable or intermittent internet connection
  • Noise or interference on the line when making telephone calls
For every phone socket that’s in use, a microfilter should be connected directly to the socket. Your device should then be plugged into the microfilter.

How do I find my master phone socket?

Your master phone socket will be the largest one in your home. It should have a line across the middle, and might also have a BT or Openreach logo.
