Media air filter:

A mechanical or media air filter is usually a 4 air filter that is

engineered under the air handler, furnace or in the return air plenum.

It is a thick filter usually changed once a year. The problem with

this type of filter is that after about 6 months it starts to fill up

and makes it hard for air to pass through the filter. This causes

static pressure in the system which reduces efficiency. If you use

this type of filter it is to your advantage to take the filter out

every four months and vacuum it out.

Electronic air filter:

Trane clean effects creates an electro static field. When air passes

through the filter it electronically charges the air flow and has the

ability to remove fine particles such as smoke or dust. These filters

offer complete control of air by removing even the finest of

containments. They work much better than the above media filter and

dont slow the air flow. It usually has washable cells to cut down on

replacement costs.

Change Your Air Filter Regularly

Check your ac filter every month during Texas extremely hot months. If

the filter looks dirty after a month, change it. At a minimum, change

the filter every 3 months (every one to two months in the summer can

help). A dirty filter will slow down air flow and make the system work

harder to keep you warm or cool wasting energy. A clean filter will

also prevent dust and dirt from building up in the system leading to

expensive maintenance and/or early system failure.
