To change the temperature in your home, your heating and air-conditioning system sucks in air from a room, pulls it over coils to heat or chill it, then blows the tempered air through ducts to the other rooms in your home. The air filter is stationed at the point where air is pulled into the system. It traps air-born particles that get sucked in with the air and keeps them from blocking the blower and clogging up the coils. Clogged coils can’t heat or cool the air passing over them, and they may damage the system. So, the air filter helps your heating and cooling system do its job, keeps it running efficiently and protects it so it will last longer.
Filters also help to keep dust from building up in your ducts, or being blown into other rooms of your house. In recent years, this air cleaning function has become more important to homeowners, and manufacturers have designed filters that use your heating and air system to remove microscopic particles like dust, pollen, pet dander, bacteria, plant and mold spores, and even smoke from the air in your home.
You always hear: Clean air filters save energy and money. Routinely changing or cleaning the filters from your home’s heating and air conditioning system helps the units run more efficiently and enjoy a longer lifespan. But what do these filters really do? How can you tell if they’re working? How often should you change them, and what should you do if they look clean when it’s time to replace them?
According to the United States Environmental Protection Agency, indoor air pollution is among the top five environmental health risks. Dust, pet dander, pollen and an array of other elements have been linked to asthma, musty odors, window condensation and even structural rot—all of which can wage war on your health as well as your pocketbook.
Luckily, you can defend yourself and your home with an air filter, the first line of defense in the battle for indoor air quality. But they need to be used properly, which means you need to change your air filter frequently.
Here are five tips to help you know when it’s time to change your air filter.
When your air filter is dirty
This is simple. Anytime you notice dust and other debris covering the filter, it’s time to change your air filter. They can’t work properly if they’re dirty.
When the manufacturer suggests
If you’re like most people and don’t frequently pull the filter from your furnace, you can mark your calendar based on manufacturer recommendations. Generally, standard one- or three-inch air filters should be changed every 30 to 60 days.
When spring & summer roll around
Now that spring is in full swing, you’re probably noticing a lot more dust and dirt in your home. Your doors and windows have been pried open after winter—and all the dust, pollen, fresh cut grass & dirt being kicked up into the air is making its way inside.
When you’re remodeling
Remodeling kicks up a lot of dirt—from sheetrock, sawdust and the comings and goings of contractors. One way to protect your air quality is to change your air filter.
When you start sneezing
Mold spores as well as pollen migrate indoors, joining the partial remains of dead dust mites and dander from cats and dogs that are already inside. Escaping the symptoms very often means escaping the causes, and that means air filtration. If you or a family member suffers from allergies, you can by or have specially built HEPA air filters for your furnace and air conditioner.
