The manufacturer should have a recommendation for how often your air filter should be changed. Most filters should be changed every one to two months.
It’s a good idea to change and clean your filter as needed because it limits the flow of air through your HVAC system and affects the level of comfort that you desire. Additionally, a dirty filter traps allergens that are released into the air. If the filter isn’t replaced regularly, these allergens can accumulate and linger on the filter for months at a time.
Another reason to change and clean your customer-provided air filter is that it improves the efficiency of your heating and cooling system. Poor efficiency means less air volume in the cabin, and it can even cause premature failure of your HVAC system. Clean filters improve the quality of air in your home, and regular cleaning can help prevent mold growth and other issues. You’ll also reduce your power consumption if you regularly change your filter.
Another sign that it’s time to change and clean your air filter is increased dust accumulation. As the air filter gets older, it’s less effective at trapping excess dust, which will circulate throughout the entire house. This is a clear sign that your air filter needs to be cleaned.
Before cleaning your air filter, turn off your HVAC system. Remove the filter from the housing and clean it well. If you’re using a permanent frame air filter, you should remove the media and dispose of it outside. Clean the filter housing and the grill to ensure maximum efficiency. Make sure to label and date your filter to prevent confusion. Additional info
When your air filter is dirty, it can cause your HVAC system to work harder than it should. This causes particulates to float in the air and contaminants to accumulate in the ductwork. It also causes your home’s energy usage to increase, which increases your monthly electrical bill. Cleaning and changing your air filter regularly will improve the efficiency of your HVAC system and save you money. If you don’t change it, your system can suffer from malfunctions. A great read
If you don’t want to buy a new filter, you can always use a disposable one. These are inexpensive and can be replaced regularly throughout the year. On the other hand, you can also use reusable ones, but they should be cleaned regularly to avoid bacterial growth. The filters should be cleaned by washing them with a hose outdoors and drying them before putting them back into the system.
