Frequently Asked Questions
Q: How often should these filters be replaced?
A: Under normal conditions (commercial HVAC use), we recommend replacement every 3-6 months. In industrial settings with heavy particulate loads, inspect monthly and replace as needed.
Q: Are these filters washable?
A: No, these are disposable pleated filters. Washing would damage the media structure and filtration efficiency. We offer washable options in our metal frame product line.
Q: What's the lead time for orders?
A: Standard orders ship within 3-5 business days. Bulk orders (100+ pieces) typically ship within 7-10 days. Expedited shipping is available.
