Furnace Air Filter Tips

Furnace Air Filter

One of the most common questions customers ask is, “How often should I replace my furnace filter?” The answer is usually once a month. However, there are a few other things to consider when replacing your furnace air filter. Here are some helpful tips.

1. Buy filters in bulk and store them near the furnace

Having replacement filters near your furnace will reduce the tendency to procrastinate and wait too long between filter changes. Also, buying a bulk package of filters is usually less expensive than purchasing individual filters.

2. Always use the correct size filter

A poor-fitting furnace filter allows dirt and debris to get around the filter and contaminate the air in your home. It can also lead to clogged air conditioner coils, reducing the efficiency of the unit and shortening the lifespan of the compressor and other components.

3. Install the filter facing right direction

Most filters have arrows indicating the direction of air flow. Putting the filter in backwards can cause the filter to work less efficiently and in some cases may cause the filter to buckle, allowing air around the filter.

4. Always turn of the power at the breaker rather than the thermostat

This will ensure that if you come in contact with any wiring near the filter enclosure you won’t get shocked.

5. Furnace filters are not air cleaners

While basic furnace filters will keep most of the dirt and debris out of your air ducts, they are not going to keep the air free of contamination. If your home has excess dust, pet dander, smoke or other contaminants, you should consider a high quality home air filtration system. These HEPA filters are designed to capture the smallest particles that can pass through most 1-inch furnace air filters.
