XPARTCO 4349 Door Latch Kit for Air Cleaner (4-Pack) Replaces Aprilaire 4349
The XPARTCO 4349 is an aftermarket replacement door latch kit compatible with Aprilaire Model 2200 and Model 2400 whole-house media air cleaners. Each cabinet uses a set of spring-loaded latches to hold the access door securely against the cabinet, keeping the seal tight so unfiltered air can't bypass the media filter. Over time these plastic latches crack, snap, or lose their spring tension from repeated opening and closing during filter changes, causing the door to sit loose, rattle, or fail to seal properly against the cabinet gasket.
This kit includes 4 latches — enough to replace every latch on one cabinet door in a single order — manufactured to match the fit and mounting points of the original Aprilaire "new style door" latch design. The genuine Aprilaire 4349 was discontinued by the manufacturer in January 2022; this XPARTCO version is an aftermarket-manufactured equivalent built to keep these still-common air cleaner cabinets in service. Installs in under 10 minutes with no tools required.
Quick Answer
The XPARTCO 4349 Door Latch Kit fixes Aprilaire Model 2200 and Model 2400 whole-house air cleaners with a loose, rattling, or poorly sealing access door caused by cracked or worn-out latches. 4-pack — enough for a full door. Designed for the Aprilaire "new style door." No tools required for installation. The genuine Aprilaire 4349 is discontinued; this is an aftermarket-manufactured equivalent. Classic symptom: door won't stay shut, or air smell/bypass around the cabinet edge.

Installation Notes
ℹ️ No Tools Required Open the air cleaner cabinet door fully. Locate each damaged or missing latch along the edge of the door. Grip the old latch and pull firmly to release it from its mounting slot — if it's already broken, remove any remaining fragments from the slot. Line up the new latch tab with the mounting slot and press firmly until it snaps into place. Repeat for each latch being replaced. Close the door and check that it seats flush and securely against the cabinet gasket with no gaps. If the door still doesn't seal evenly after replacing all latches, check the door hinge alignment and the condition of the cabinet gasket itself.
Frequently Asked Questions
Is the genuine Aprilaire 4349 still available?
No — Aprilaire discontinued the genuine 4349 latch kit in January 2022. This XPARTCO version is an aftermarket-manufactured equivalent designed to keep still-common Model 2200 and 2400 cabinets in service now that the original part is no longer produced.
How many latches come in this kit, and how many do I need?
This kit includes 4 latches, which is a full set for one cabinet door. Most installers replace all four at once even if only one or two have failed, since the remaining originals are usually close behind in wear.
Will this fit my Aprilaire air cleaner?
This kit is designed for the "new style door" used on Model 2200 and 2400 units. Earlier cabinets used a different door and latch design that this kit will not fit. Compare your existing latch shape to the product photos, or contact our support team with your model number to confirm before ordering.
Do I need any tools to install this?
No. The latches are a snap-fit design — pull the old one out of its mounting slot and press the new one in firmly until it clicks into place. No screwdrivers or other tools are needed.
