Your guide to microfilters

A microfilter is a small device that stops your phone and broadband signals from interfering with each other. They have two connection ports:

  • An ADSL or DSL port for connecting your router
  • A Phone port for connecting your telephone, digital TV box or answering machine

Without microfilters you're more likely to experience slow broadband speed, drops in your connection or noise on your phone line.

When to use microfilters

You'll only need to use microfilters if you have a standard main phone socket with one port on the front. For your microfilters to work properly, you'll need to plug one into every socket you're using in your home. You'll get two microfilters with your router, but if you need more please contact us.


How to use microfilters

Here's how to use your microfilters correctly:

  • Use one microfilter per socket
  • Plug a microfilter into every socket you're using in your home
  • Don't plug microfilters into empty sockets you aren't using.
  • If you don’t have enough microfilters for all the sockets you’re using, unplug some devices and leave them unplugged until you can get some more. 


Connecting your microfilters

Microfilters are easy to connect, all you have to do is:

  1. Unplug any devices that are plugged into your main phone socket
  2. Plug your microfilter into your main phone socket
  3. Plug your phone cable (or other device) into the Phone socket on your microfilter
  4. If this is the socket you want to connect your router to, plug your router's broadband cable into the ADSL/DSL port on your microfilter
