How long do air filters last in furnace?

Change Your Filters Regularly For example, a one inch furnace filter should be changed out every one to three months. A three to four-inch filter can last for six to nine months. If you have a thick five to six-inch filter, it can last from nine to twelve months.

How do I know when to replace my furnace filter?

The best test to know if a furnace filter is ready to be changed is to hold it up to a bright light . If you can still see light through the filter then air is still getting through the filter. If you suspect the filter is dirty enough to restrict the air flow, then change it out to a new filter.

How do I know what furnace filter to buy?

First, locate the filter slot in your furnace/air handler. Some homes have filters behind their return vents as well. Furnace filter size is measured using length, width, and depth. For example, a furnace filter that measures 18”x16”x1” is 18 inches long, 16 inches wide, and 1-inch deep.

How do I know what air filter to buy?

What is the difference between Merv 8 and MERV 11?

If you’re worried about the effects of breathing in fine air particles, that’s another reason to choose a MERV 11 air filter over a MERV 8 air filter. Fine air particles are 2.5 microns and smaller. MERV 11 air filters can filter out a large percentage of fine particles, but a MERV 8 air filter can’t.

Is MERV 8 or MERV 11 better?

A MERV 8 filter should pick up most animal dander, but if you have 2 or more pets you may need a MERV 11 to completely eliminate those harmful particles from your home’s air. A MERV 11 filter would make their lives a lot more comfortable because it can pick up even smaller particles than a MERV 8 filter.

What happens if you put furnace filter in backwards?

When a furnace filter is placed backwards, the fibers can’t do their job properly. This means your furnace has to work harder to generate the same air flow, resulting in increased energy costs. Particles are also allowed to build up irregularly, making the furnace working even harder to draw air.

Why does my furnace filter get dirty so fast?

Leaky Duct Work According to ENERGY STAR, a typical house loses 20-30% of air through leaks in the duct work and poor duct connections. Leaving these untreated can not only kill your furnace filter quickly, but also result in higher energy bills.

What happens if you don’t change your furnace filter?

Short Cycling If the air filter is not serviced often enough, it will eventually become clogged to the point that air cannot pass through it. When the furnace is operating, the lack of air flow will trap the heat in the system. Without a new air filter, the furnace will overheat every time it starts up again.

Is it OK to run the furnace without a filter?

Technically, you can temporarily run a furnace without a filter. However, it’s important to emphasize the word “temporarily” here. Poor air quality: For one, not having a filter in place means there is nothing to prevent dust and debris from being sucked into your furnace and recirculated throughout your home.
