Use a furnace filter

A furnace filter is designed to trap dirt and dust. If too much dirt and dust collect on the filter, your furnace will run less efficiently, wasting energy and costing you money.

Replacing your furnace filter on a regular basis is an easy way to save energy.

A dirty furnace filter can result in a lot of wasted energy, since air can’t get through the dust and dirt. You can reduce your furnace’s energy consumption by up to 15% by making sure your filter is always clean. It used to be that furnace filters had to be replaced every 2 to 3 months, creating a huge amount of waste.

Now you can buy permanent electrostatic furnace filters that are washable. Not only does this reduce waste, You should have a look at the filter once a month if you’re using the furnace a lot.

You should wash the filter every 2 to 3 months, including the summer months if you have central air conditioning. If you have pets, you may need to replace the filter more frequently.

To wash your reusable furnace filter, you just need to rinse it thoroughly under a sink, or spray it off with a hose.

Now you can even buy furnace filters made out of recycled materials to make your furnace filter even more green.
