Frequently Asked Questions

Q: What size does this activated carbon pre-filter fabric come in, and can I cut it to fit my AC unit?

A: Yes! The pre-filter fabric measures 100 cm × 100 cm (approximately 39.4" × 39.4"), giving you a full square meter of material. It is specifically designed to be cut-to-fit, so you can trim it to match any air conditioner filter frame, ventilation grille, or air purifier intake size with ordinary scissors.

Q: How does the activated carbon layer help with air quality?

A: Activated carbon is highly porous and works by adsorbing odor-causing molecules, dust particles, and various airborne contaminants as air passes through the fabric. When installed as a pre-filter in your AC or HVAC system, it intercepts these particles before they reach your primary filter, helping keep your indoor air fresher and extending the life of your main filter.

Q: How often should I replace this pre-filter fabric?

A: Replacement frequency depends on usage, air quality, and environmental conditions. As a general guideline, inspect the fabric every 4–8 weeks. If it appears visibly dirty, discolored, or airflow seems restricted, it's time to cut and install a fresh piece. Regular replacement ensures optimal air filtration performance.

Q: Is this pre-filter compatible with all air conditioner brands and models?

A: Because it's a cut-to-fit fabric roll, it is universally compatible with virtually any air conditioner brand, model, or style — including window units, split systems, portable AC units, ventilation grilles, and more. Simply measure your filter slot and trim the fabric accordingly.
