Will this MERV 13 filter replace both my original Honeywell and Lennox filters?
Yes. This premium aftermarket MERV 13 media air filter is an exact dimensional upgrade for the OEM Honeywell FC100A1029 and the Lennox Healthy Climate X6670 filters. It provides superior filtration compared to a standard MERV 11 filter without restricting your HVAC system's airflow.
Why is this filter listed as both a 4-inch and a 5-inch depth filter?
Honeywell officially brands this specific media cabinet track as a 4-inch deep filter, while Lennox, Carrier, and Bryant brand their equivalent system tracks as a 5-inch deep filter. The exact actual physical dimensions of our replacement filter are 15-7/8" x 24-7/8" x 4-3/8", making it a universal cross-reference fit for both systems. Always verify your current filter casing sizes before ordering to ensure a tight seal.
How many filters come in one box?
This item is sold as a convenient 3-Pack (case of 3 filters total). Upgrading to a multi-pack case ensures you have a continuous seasonal supply of healthy indoor air while saving on replacement costs.
Where are these HVAC furnace filters manufactured?
This air filter proudly Made in Canada by United Filter. We manufacture our products using robust, moisture-resistant beverage board frames and premium synthetic pleated media to maintain peak airflow performance without causing static pressure drops in your furnace system.

📢 The frequency of air filter replacement depends on several factors, such as filter type, indoor air quality, household size, and whether you have pets. In general, it is recommended to replace standard 1-inch filters every 1 to 3 months. High-efficiency filters may last longer, up to 6 to 12 months.
📢 High-efficiency air filters, such as HEPA filters, can remove smaller particles and allergens. They are worth it if you or your family members suffer from allergies, asthma, or respiratory issues. However, they can also put additional strain on HVAC systems not designed for them.
📢 MERV (Minimum Efficiency Reporting Value) is a rating system for air filters that ranges from 1 to 16. Higher MERV ratings indicate better filtration. HEPA (High-Efficiency Particulate Air) filters are a specific type of high-efficiency filter that can capture at least 99.97% of particles as small as 0.3 microns.
📢 Some air filters are designed to help with odors by incorporating activated carbon layers that absorb volatile organic compounds (VOCs) and other odor-causing particles. Standard particulate filters generally won't address odors.
📢 To choose the right air filter, consider factors such as the size of the filter required by your HVAC system, desired MERV rating, any specific allergies or health concerns, and whether odor control is important. Also, ensure that the filter won't overly restrict airflow for your HVAC system.

"United Filter took the time to make sure we had purchased the right filter AFTER we had placed our order. It was a mistake on our end which we did not notice until United Filter sent us an email asking for specific measurements. Turns out we had purchased the wrong product and they were kind enough to change our order prior to shipment. They saved us a lot of time and money by doing so. Much appreciated!"
"My filters arrived as ordered and quickly to my door. Thank you very much for the great service."
"The filter for my heat-pump is an uncommon size. United Filter had the size I needed, and they work great,"
