Frequently Asked Questions
How frequently should I replace my air filter?
It is recommended to replace your air filter every 90 days. However, if your household includes multiple pets, smokers, or experiences high traffic, it is advisable to inspect your filter more frequently. When upgrading from a lower MERV rating or a fiberglass filter, it is prudent to check your filter within the first 30 days.
How do I replace my air filter?
To replace your air filter, first locate your furnace filters and turn off your HVAC system. Observe the airflow direction on the old filter, then carefully discard it. Record the installation date of the new filter and install it with the arrows pointing in the same direction. Enjoy improved air quality!
What size filter do I require?
The nominal size or dimensions of your current air filter are typically found on its side. If the previous filter is unavailable, measure your intake vent to determine the actual size of your air filter. "Nominal" refers to the product sizing chart that fits your intake vent, while "actual" size refers to the precise measurements of your air filter dimensions, which are slightly smaller than the intake vent dimensions. For instance, a 20 x 20 x 1 air filter may be listed as 19.5" x 19.5" x 0.75" on the side. Most HVAC filters are identified by the nominal size, which is the actual size rounded up to the nearest inch.
Can I use your filters if I have a specific brand of air filter?
Yes, you can! Before purchasing, ensure that you are comparing the exact size of your current filter with our exact size.
