🔍 Frequently Asked Questions

Q: Is this an exact replacement for Lennox X6670?

A: Yes! Our Atomic X6670 compatible filter has identical dimensions (15-3/4" × 24-3/4" × 4-3/8") and the same MERV 11 rating as the Lennox OEM X6670. It's manufactured to the same specifications and offers the same filtration performance.

Q: Will this void my HVAC warranty?

A: No. Using aftermarket filters does not void your HVAC warranty. Federal law (Magnuson-Moss Warranty Act) protects consumers' right to use compatible replacement parts. Our filters meet all OEM specifications.

Q: How do I know if this will fit my system?

A: This filter fits Lennox air cleaner model HCC16-28 (also called X6660). If you currently use Lennox part numbers X6670, HCF16-10, or HCF16-11, this is your compatible replacement. Still unsure? Contact us with your model number!

Q: What's the difference between MERV 11 and MERV 13?

A: MERV 11 captures 85% of particles from (3-10 microns),  greater than or equal to 65% of particles from (1.0-3.0 microns) and is ideal for most homes. MERV 13 captures greater than or equal to 90% but may restrict airflow in systems not designed(i.e. not properly sized duct work) for it or older. MERV 11 provides excellent air quality without straining your HVAC system. Lennox systems are designed for a MERV 13 and MERV 16 upgrade.

Q: Can I wash and reuse this filter?

A: No, this is a disposable filter. Washing damages the electrostatically charged media and reduces filtration efficiency. For best performance and air quality, replace every 6 months with a new filter.

Q: Why does the package say 16x25x5 but actual size is different?

A: This is standard in the industry. "16x25x5" is the nominal (rounded) size for easy shopping. The actual size (15-3/4" × 24-3/4" × 4-3/8") allows proper fit in your air cleaner cabinet. Always match actual dimensions when ordering.

Q: What makes Atomic filters better than cheap options?

A: Atomic filters use premium synthetic media with electrostatic charging for superior particle capture. Cheap filters often use lower-grade materials that clog faster and allow more particles through. Our UL 900 Class 2 certification ensures consistent quality.

Q: How quickly will this ship?

A: Orders placed before 11:30 AM EST ship the same business day. Most customers receive their filters within 3-5 business days. We offer free shipping on orders over [your threshold].

Q: Do you offer filters for other Lennox models?

A: Yes! We manufacture compatible filters for most Lennox air cleaner models. Browse our complete Lennox filter collection or contact us to find the right filter for your specific model number.

Q: What if the filter doesn't fit?

A: We stand behind our products with a 30-day satisfaction guarantee. If you're not completely satisfied, contact us for a hassle-free return or exchange.
