Frequently Asked Questions
Are non-pleated fiberglass filters as effective as pleated filters?
Non-pleated fiberglass filters capture larger dust and lint particles and are excellent for minimizing airflow restriction. Pleated filters usually capture smaller particles and allergens more effectively but can increase airflow resistance. Choose based on your system’s tolerance for resistance and your air-quality priorities.
Will a low-restriction filter damage my AC or furnace?
No — in fact, using a low-resistance filter can reduce stress on older or marginally sized systems by allowing the fan to move air more easily. The important part is to use the correct filter thickness and size so there’s no bypass or air leakage around the filter.
How often should I replace these filters?
For basic non-pleated fiberglass filters, a common schedule is every 1–3 months depending on household dust, pets, and usage. Because these come in 12-packs, many users set a quarterly replacement routine. Check the filter visually: when it appears dirty or restricts airflow, it’s time to change it.
