Do you have a furnace in your home? If so, you may be wondering if you need an air filter. The answer is yes! All furnaces and heat pumps require filters to keep dust and debris from entering the return duct and damaging the fan. Without a filter, the HVAC system would recirculate allergens into the air, making it difficult to breathe. It is possible to operate a furnace without a filter, but it should only be done on a temporary basis. The primary purpose of an air filter is to trap airborne contaminants and protect the heating and cooling system.
As the name suggests, it does not directly improve air quality. If you run your furnace without a filter for an extended period of time, dust and debris can build up and clog the system. Furnaces are often placed in dusty areas, so it is important to replace the filter regularly. If you neglect to do so, you may start to notice an increase in dust on your furniture and floors. If someone in your household has allergies, not having a filter can make them worse. There are many different types of filters available, so it is best to consult with a professional to determine which one will work best for your system.
Some filters are more efficient at trapping certain particles than others. Contrary to popular belief, the primary purpose of an air filter is to protect your HVAC equipment. If you put your hand against a vent and there is not much airflow, it could be because the filter is clogged or missing. In homes without indoor air quality equipment such as air purifiers or air filters, the oven filter is the only line of defense against pollutants in the air. This means that it will fill up faster and need to be replaced more often. If managing your furnace's air filter becomes too frustrating, there are some strategies you can use to make sure you remember to perform this essential household maintenance task. For example, if you have furry family members living in your home, you should change the filter every 30 days.
You can also take a look at the filter replacement aisle at your favorite hardware store to find one that fits your needs. To sum up, all furnaces and heat pumps require filters to keep dust and debris from entering the return duct and damaging the fan. It is possible to operate a furnace without a filter on a temporary basis, but it should not be done for an extended period of time. There are many different types of filters available, so it is best to consult with a professional to determine which one will work best for your system.
