VOYAR 413 Replacement Filter – MERV-13 16x28x4 for Aprilaire 413

VOYAR 413 Replacement Filter: easy fit, solid performance for Aprilaire 413 systems

Meet the VOYAR 413 replacement filter, designed to fit Aprilaire 413 whole-house purifiers and compatible models. The unit’s actual size is 16x28x4, which sits alongside a nominal spec of 16x25x4 to help you identify the correct replacement. Note that this filter does not fit the 1413 upgrade kit (models 2400 or 2140). By aligning with these details, you can select a replacement that integrates cleanly with your existing housing and airflow path.

Whether you’re upgrading an older system or sorting seasonal maintenance, VOYAR aims to provide a straightforward replacement that minimizes downtime and preserves the smooth operation you expect from your filtration setup.

Smart, tool-free installation with a foldable design

The standout feature is a foldable frame that unfolds to its full shape and folds for storage when not in use. Four bendable metal strips support the filter during operation, helping it stay firm in high airflow. Four sealing strips on the top and bottom minimize air bypass, supporting a more consistent seal across the filter surface.

• Unpack, unfold, slide in, close the door—no extra assembly required
• No cardboard or metal screws needed, thanks to an innovative, rail-free design
• Foldable frame makes storage compact and handling simple

What to expect in performance and airflow

The VOYAR 413 filter carries a MERV 13 rating, designed to capture a broad range of particles as small as 0.3 microns. The soft, light fiber material provides good air permeability with low resistance, supporting steady airflow through your home. By maintaining cleaner airflow paths, you may notice less dust buildup on surfaces and more consistent filtration across rooms.

• Efficiently targets common indoor irritants such as dust, pollen, and pet dander
• Low-resistance design helps sustain steady airflow over time

Maintenance guidance and compatible models

For typical home environments, consider replacing the filter every 6–12 months. Factors like pet presence, smoking, or heavy dust can influence the replacement interval. This VOYAR filter is designed to slot into compatible Aprilaire 413 models (and related units) without modification, delivering a reliable upgrade in an existing filtration system.

Choosing VOYAR means opting for a replacement that emphasizes straightforward fit, practical performance, and easy upkeep as part of your HVAC maintenance routine.
