MERV Rating:
MERV 8: captures basic dust and debris
MERV 11: captures pet dander and light allergens
MERV 13: finer particles, if your system can support higher resistance
Quantity: Multi-packs reduce cost per filter and help you stay stocked during the winter
In most homes, the furnace filter is located near the blower compartment—typically in a slot or behind a panel at the side or base of the unit. Furnaces are often installed in basements, garages, utility closets, or attics. Some homes also use return grille filters. Be sure to check all intake areas.
A properly fitting filter helps prevent dust from bypassing the media and reaching the blower motor or heat exchanger. Loose or undersized filters can reduce efficiency and increase wear. If your filter doesn’t sit tightly, consider ordering a custom size. Filterbuy offers both standard and custom options for a proper seal.
Check your furnace filter every month when it’s in use. Most households benefit from replacing the filter every 1 to 3 months. Change it sooner if you notice:
Visible dust buildup on the filter
Weak airflow at vents
Excess dust inside your home
Longer or more frequent furnace cycles
1. Turn off the system at the thermostat
2. Remove the old filter and note the airflow direction
3. Insert the new filter with the arrow pointing toward the furnace

5. Turn the system back on and confirm airflow is normal
