Filters FAQs

What is the difference between a 1" filter and a 5" filter?

A 5” filter has a higher MERV rating. A MERV rating determined how fine a particulate the filter will catch. The higher the MERV rating, the smaller a particle the filter will remove from the air. 5” filters catch more dust and dirt than 1” filter.

There are a number of different Indoor Air Quality (IAQ) products that can help with your allergies. Ultraviolet lights, Thicker High Grade Filters, and Fresh Air Ventilation Systems to name a few. Please consult a 72 Degrees professional to find out which of these products would help you.

What is this orange and white filter in my furnace?

We recommend, sell, and install Fiberbond filters which are orange on one side and white onthe other. We feel they are a better filter than the standard 1” wide filter with the cardboard frame. The fiberbond frame is on the inside of the filter which keeps air from flowing around the outside of the frame and not being filtered. We recommend changing them every 3 months. The orange side is facing the furnace when installing.

How do I know which direction to install my filter?

Filters with the cardboard frame around the outside have an airflow arrow and the arrow should point towards the furnace. The orange and white Fiberbond filters should have the orange side towards the furnace.

How often should I change my filter?

1” filters should be checked monthly and changed as needed. Fiberbond filters typically need to be changed every 3 months and the type with the cardboard frame typically should be changed monthly. Thicker filters like 4” or 5” typically should be changed every 6 months to 1 year.

What does Merv mean on my filter?

The acronym MERV stands for "Minimum Efficiency Reporting Value." MERV ratings are used to rate the ability of an air cleaner filter to remove dust from the air as it passes through thefilter. MERV is a standard used to measure the overall efficiency of a filter. Fiberbond filters are a Merv 8 rated filter.

Where is the filter for my furnace located?

Generally the filter is located on the side of your furnace between the furnace and the cold air return duct work towards the lower half of your furnace. Mobile home furnaces the filter is inside the door of the furnace. GeoThermal systems the filter is on the side of the unit.
