Furnace Filters Need to be Changed Regularly


Dust, dirt, pollen, carpet fibers and pet dander are some of the things that furnace filters take out of the air to help keep your house cleaner and keep household allergens under control. When your filter is working hard your furnace runs much more efficiently. But your filter can’t do its job properly if it is dirty or damaged. These are some of the reasons to change your furnace filter regularly.

Furnace filters are greatly neglected due to the perceived inconvenience of maintaining them. This is true even though a furnace is a vital part of a home. Without it, there would be no heat during those cold winter days. After all, the furnace is all the way down in your basement where it may be damp and the lighting is bad. Who wants to go down there and fiddle around with a filthy furnace air filter that may get your clothes all dirty? There are many reasons to take that trip downstairs regularly and to make sure that your filter is clean and your furnace is operating properly.

The Benefits of Changing Furnace Filters

furnace filtersThe benefits of changing furnace filters regularly are many. Think about the purpose of these home filters in the first place. A furnace filter is a home air purifier meant to take the dust out of the air flowing in your home and improve indoor air quality. If the filter is clogged with dust the furnace works harder trying to get air out and circulating in your home. The longer and harder the furnace works, the faster it will burn out and the higher your utilities bills will be. Imagine how hard you would have to suck on a straw with something stuck in the middle of it. You’d suck and suck to get a bit of liquid through the straw and after all that effort you could collapse. Your furnace is the same way. An air filter for home or office use must be kept clean to work efficiently and protect your furnace.

Did you ever neglect a small cavity just to have it turn into a route canal? If you had just taken care of the tooth when the problem was small, you would have saved yourself a lot of time, pain and money. It is the same with your furnace. If you change the furnace air filters regularly and take care of the furnace, you’ll save a lot of time and expense in the long run.

When changing residential air filters, it is a good idea to use the same brand filters as your furnace. For example if you have a Honeywell furnace, use a Honeywell air filter. I mention Honeywell furnace filters because they are considered some of the best on the market. If you are looking for a Honeywell furnace filter, you can find it cheaper online. The company makes all kinds of house filters and other air quality products including washable, disposable and Honeywell electronic furnace filters.

Buying your heater filters in bulk is another tip to make sure you always have them on hand. Remove them from the box and mark the date that you intend to change the filter on each one so that you can see at a glance if  your current filter is past the date or not when it should be changed.

The Dangers of not Changing Furnace Filters

We already discussed that changing your home air filters regularly will save you money on your utility bill as well as the time and expensive of replacing furnace parts or worst case scenario your whole furnace. What about the serious dangers to you and your family if you neglect your furnace? First of all, a dirty furnace with clogged filters at best will allow a lot of dust to circulate in your home which you and your family will breathe in. At worst, there are fumes that the furnace will give off that are very unhealthy to breathe in. In today’s day and age where people spend a lot of time at home on their computers, on the TV or working from home, they would spend a lot of time breathing in these toxins. That is what makes proper filtering and ventilation important.

The very worst danger is that a neglected and dirty furnace can actually blow up or cause a fire. Imagine the risk to your valuable items not to mention your invaluable family members and pets. This is a danger that can be prevented by regularly checking and changing your furnace filters.

Taking the time to take care of your furnace will save you from health problems that home air purifiers can counter, will save you time and will certainly save you a lot of money.

Types of Furnace Filters

An electrostatic furnace filter uses the technology of static electricity to remove dust from the air. This has the benefit of having very little impact on air flow into your furnace. The reason this is beneficial is because some hvac filters can limit air flow significantly causing the furnace to overwork which reduces its efficiency. Electrostatic filters are considered permanent or reusable furnace filters since they do not need to be replaced often.

A reusable furnace filter is otherwise known as a washable furnace filter. This means that you do not have to spend money every month on disposable filters which you might otherwise think are a good choice as cheap furnace filters. Washable furnace filters will save you hundreds of dollars in the long run.

A pleated furnace filter is much more efficient then a disposable filter. They are available in both 30% as well as 50% efficiancy variations. Compare this to disposable filters that filter a mere 8% of airborne particles. Because pleated furnace filters are more efficient they do a better job at protecting your furnace parts such as the heating coil and your furnace’s motor. That means your furnace doesn’t have to work as hard to heat your home. Some other advantages to pleated air filters is that they help maintain a cleaner home, protect your home from bacterial growth, last longer then disposable, require many fewer changes and save you money over purchasing disposable filters monthly.
