❓ Frequently Asked Questions
1. What makes 20x20x1 pleated filters better than fiberglass filters?
Pleated filters have a larger surface area and are made with electrostatically charged media that captures more dust, pollen, and allergens.

2. How often should I replace a 20x20x1 HVAC filter?
Most pleated 20x20x1 filters should be replaced every 60 to 90 days. However, in high-use environments (pets, allergies, construction), monthly replacement is recommended. We designed our 12-pack bulk option to make routine changes affordable and hassle-free — no last-minute trips to the store.
