AprilAire 401 Replacement Furnace Filter for AprilAire 2400, Space-Gard 2400 Whole-House Air Purifiers - MERV 10, 16x25x6 Air Filter (Pack of 1)

This filter is a perfect fit for the AprilAire 2400 and makes maintenance simple. Installation is straightforward, and once in place it noticeably improves air quality, catching dust and allergens effectively. The build quality is solid, and it lasts a long time before needing to be replaced, which makes it a good value over time. I also appreciate that it seals well, so there’s no air bypassing the filter. Reliable, easy to install, and long-lasting—a solid replacement that keeps the system running smoothly.

These are excellent quality filters. I have used them many times and they always perform well. Yes, they do require some assembly to use but it’s not hard and you are rewarded with very clean air to breathe and they do last longer than the other kind.

Tried a different brand and spent an hour cutting and fitting the filter to fit! Aprilaire was easy to install and finished in a few minutes!

I replaced the original filter with this filter. It is a higher performing filter. Some assembly required.

I have ordered this item several times with no issue. When changing my filters this year, I discovered that I was missing a pleat in the filter (on the one filter) and that filter was very frayed. I went ahead and installed and just hope that filter does what it’s suppose to do for a year. The other filter was fine.

This air filter has good quality and in a good price. It fits the air condition system very well and make the air clean. Will buy again when needed. Thanks.

This review is on the AprilAire 1413 Performance Upgrade Filter Kit. It’s packaged very well for shipping and Amazon arrived at my door on Christmas Eve, just 2 days after I ordered it. All of the components have the look and feel of the highest quality and are very well made and designed. The assembly only took a few minutes to complete. The 6 metal frame pieces simply snap together. After removing the old, cumbersome filter from my Space-Gard 2400 housing, the new frame slides into place on the existing guides inside the housing. The new 413 pleated filter media has plastic guides securely attached to the top and bottom that simply slide into the guides on the new frame assembly. Reattach the door to the housing per the well illustrated instructions and you’re all done ! One of the best features of this filter kit is that you have the ability to use optional high performance filters offered by AprilAire. The standard 401 filters are okay but they can’t compare to the quality of the 413, 413 CBN (carbon) or the 416 HEPA style filters. Clean air in my home is important. That’s why I avoid the lower cost and quality imported filters. Amazon carries genuine American made AprilAire Filters 🇺🇸.

Great Item

I've got the older 2400 Spaceguard and this fits perfectly! Its even made the furnace much quieter. I couldn't get over how snug the fit is. I've used a variety I've the years. Mostly the Pop-Up model in an 11 Merv. I found the resistance caused vibration. Yet this one is even denser at the Merv 13 rating and it seals so well it seemed to nearly eliminate vibration.

Fits and quality is good.

This was a replacement filter. The filter fit the container perfectly. thanks.

This is the factory replacement part for this filter system and, as such, fit perfectly. I have used generic replacements and was not really satisfied.

Easy to install - Arrived early
