If you have a moment, we would like to give you a quick breakdown on the importance of changing the air filter in your home’s HVAC system, as well as tell you how often your filter needs to be changed.

But question is: Why is Changing Your Air Filter so Important?

There are a number of different types of filters available on the market, each offering different benefits, but the fact remains that all types of filters need to checked, maintained and changed in order to function properly and safely.

To that end, why is changing your air filter so important?

First of all, a clogged air filter can cause extensive damage to your system. Thus, if you check your air filter’s condition regularly, you ensure the longevity of your system — saving yourself thousands in possible repair and replacement costs. Dirt and neglect are one of the leading causes of heating and cooling systems failing, yet such failure is completely avoidable.

Secondly, changing the air filter in your system ensures cleaner, fresher, healthier air. This is better for everyone in your home, particularly children and the elderly, and most especially for those suffering from allergies and/or asthma. In referring to the latter, a clean air filter means you are not constantly circulating dust, dust mites, pollen and other small particles in the air. Instead, your system will be able to purify the air, leaving it clean and healthy.

Thirdly, aside from protecting the HVAC system from unnecessary damage, cleaning out or changing a clogged air filter will also save you a significant amount on operating costs. In simplest terms, a dirty air filter uses much more energy than a new, clean air filter, which means a much higher electricity bill for you. You can, by keeping your air filter clean and in good condition, save up to 15% on utility costs.

To the above point on energy wastage, failing to clean and replace your air filter on a regular basis is failing the environment. An air filter that is clogged means a harder working HVAC system, thus it also means a lot of carbon monoxide and other greenhouse gasses by extension being released. Going green and running your home in an eco-friendly manner need not necessarily mean bending over backwards and giving up all forms of comfort. Something as simple as changing an air filter regularly can go a long way in making a difference.

Thus, to conclude, changing your HVAC system’s air filter is important in every which way. Economically, health-wise and environmentally it simply makes sense!

To that point, how often should your air filter be changed? It differs depending on the different types of filters, but anywhere between 1 and 3 months is advised, with the former being preferable and the latter being the absolute maximum you should allow between changes.
