How Often Should Furnace Filters be Changed?
Because the life of each furnace filter varies from household to household, it is best to avoid comparing different household HVAC systems and furnaces. The replacement of furnace filters is completely dependent on the condition of the household. A variety of factors could have contributed to its clogging. The most common cause of furnace filter clogging is dust. Some homes are prone to dust infiltration, and despite regular cleaning, dust always manages to attach itself to home appliances, furniture, bedsheets, and even curtains. Check the filter of your furnace if it is gray and dust has almost completely covered it, and the furnace runs faster than usual if you live in a dusty environment. Then you've already got a green light to replace your filter.
Keeping some furry friends at home may also increase the likelihood of clogged filters. Our pet's fur contributes to the amount of pet dander in the air and may eventually clog your filter.
When you remodel your home, the lifespan of your filter may be significantly shortened. It is a well-known fact that remodeling generates a great deal of dust and debris. Sanding, scraping, and even floor installation can cause airborne dust and debris.

There could be a zillion other factors that contribute to the clogging of your furnace filter and the need to replace it. Replacing the filter ensures that dust-related particles are kept from circulating inside the house.
It may appear that replacing the furnace is a simple task. Simply loosen the screws in its filter cover if it is located behind the return air vent. If it's the filter for the side furnace, simply pull it out of the slot. Because the filter is clogged with dust, tiny hair particles, and other air particles, you can expect it to be dirty and must be disposed of properly, along with your other trash. Simply insert the replacement filter into the slot after removing the clogged filter. After that, set a date to indicate the date of the filter replacement.
You must be aware of the replacement date in order to determine the date on which it must be replaced. Under normal conditions, filter replacement should be done every ninety days. However, it is entirely dependent on your home's condition and the type of weather in your area.
If you live in a warm climate, chances are you have an air conditioner. Nonetheless, you must inspect your HVAC system on a regular basis for dust and dirt that may have been sucked by the air conditioner system. Make sure your filter is clean if you want to enjoy the coolness of clean air.
Living in Southwest that has temperate weather may connote that you could have used the furnace a couple of times and thereby may follow the 90-day standard replacement period, but the scenario is not the same if you are a Northern dweller that it is a must for you to use your furnace every day and it could have drawn more air into its filter then do not follow the standard 90-day rather change your filter within the 30 or 60-day period.
You should also observe the Minimum Efficiency Reporting Value of the filter (MERV). Keep in mind that a dense filter should be changed on a regular basis. The ideal MERV for residential furnaces is between 6 and 12, and anything less may indicate that the filter is not effectively blocking airborne dust and particles. MERVs of 12 and above are intended for use in industrial, commercial, and hospital settings.
The level of MERV determines the filter's efficiency in blocking airborne dust, particles, viruses, and bacteria. A higher MERV rating indicates that it is more effective at blocking airborne particles. The reason for this is that higher MERV means smaller holes, which prevent particulates from passing through. However, because it has smaller holes, it is more likely to become clogged quickly, necessitating frequent filter replacement.
Filters that are clogged have a negative impact on home air quality and force the furnace to work harder, reducing the useful life of the furnace. The most dependable furnace MERV rating is specified in the owner's manual. Before changing the furnace every 90 days, it should have a MERV rating of 6 to 9, and every 60 days if it has a rating of 10 to 12.
