Frequently Asked Questions

 

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 5-Pack (case of 5 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 is 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.

Why brave the “river” if you can go to the source?

"The amazon listing was unclear about the correct dimensions of the filter, so I decided to check out the manufacturer’s site. It took a minute but I was able to find the exact size of filter I needed. After I placed my order, I received an email double-checking whether I had the correct model, since I would have to pay for return postage. The shipment arrived much sooner than expected. With shipping, I might have spent a few dollars more than on the other site (where the filters cost more to begin with), But the peace of mind that I had ordered the right thing is more than worth it to me. I will definitely order direct again."
