Getting a little heated over your furnace filters? Here's a quick rundown.

If your furnace is huffin' and puffin' and full of hot air, you need to make sure the filter is changed often so it isn't overworked. There are four different types of furnace filters. Most work in any furnace, but there are specific situations where one might be a better choice over the rest. Also, regardless of the filter you choose, find one with a MERV rating of at least five or higher. This means it is better at capturing smaller particles in the air, including allergens and bacteria.

Pleated Filters These are the most common types of furnace filters. They last three months between filter changes and trap pollutants without hindering airflow. Most can capture allergens and even bacteria. They are made to be recycled after use making them eco-friendly as well. The best overall pleated filters are by FilterBuy, and this 4-pack is a decent investment for a full year of filtering. Though for an even better value on pleated filters, consider the Filtrete MPR 300 6-pack.

Fiberglass Filters Fiberglass filters are also sometimes called synthetic filters. These filters, like the True Blue 116251 are the best for trapping dust and large dirt particles that tend to corrode the fan, motor, and heat exchangers of your furnace. They also tend to be the cheapest furnace filters. The fiberglass filling keeps the air flowing well from your furnace, however, synthetic filters don't capture other contaminants in the air, including allergens and pet dander. It isn't the best if you hope to maintain the overall health of you and your family in addition to keeping your furnace clean. Also, fiberglass filters need to be replaced monthly rather than every three months.

Electrostatic Filters These filters are made for a specific type of furnace system known as an electrostatic furnace. They use a special type of fiber that attracts and captures air particles while also allowing proper airflow through your unit. It's really good at capturing pollen and allergens. These filters are typically made to be washed and reused. However, if you put a washed filter back into your furnace without it being completely dry, the filter will grow mildew and moldy. The best electrostatic filter is by Trophy Air. However, you can use the Nordic Pure MERV 12 filter. This is a combined electrostatic and pleated filter that can be used in both electrostatic and traditional furnaces. It is also disposable.

HEPA Filters HEPA, or high efficiency particulate air filters, trap particles so small even bacteria and viruses can pass through them. They have a MERV rating of over 13 with the highest having a rating of 16. While HEPA filters are amazing for cleaning the air, they cut off most of the airflow of your furnace, causing it to work harder and costing you both in money and in higher energy use. Experts don't recommend using a true HEPA filter in your furnace, but one with a MERV rating of 13 will come pretty close. It just won't capture the smallest viruses in the air. The Aerostar Home Max is a pleated furnace filter, but with a MERV of 13, it is an excellent choice for allergy sufferers, or for those who want the cleanest air possible flowing from their furnace.
