Pros
- Pleasantly accurate dimensions: 15.63 x 24.13 x 4.88 inches for a snug fit.
- Excellent build quality and foam gasket for a proper seal.
- Manufactured in the USA with moisture-resistant construction.
- High customer satisfaction rating for fit and performance.
- Direct replacement for popular Air Bear models.
Cons
- The paper-based housing is less thick and sturdy than the OEM Trion Air Bear filter.
- Not an OEM product: some users may prefer branded Trion filters for peace of mind.
- Limited to MERV 8 performance, which is adequate for standard residential needs but not for those requiring higher filtration (e.g., MERV 11 or 13).
The AIRx Filters 16x25x5 MERV 8 replacement is a strong contender for anyone needing a reliable, budget-friendly filter for their HVAC system. Its design fits exactly as advertised, making it a great choice for homeowners who value precision fit and ease of installation. Specifically compatible with Air Bear 229990-105 systems, this filter targets the dust, pollen, and common irritants that can accumulate in your home.
What makes this filter stand out is its electrostatic charge, which actively attracts particles rather than simply trapping them. The synthetic gradient media performs well under real-world conditions, and customers consistently praise its fit and performance. The moisture-resistant frame ensures it stays dry during humidity spikes, adding longevity.
Build quality is excellent for a MERV 8 filter: all materials from the paperboard to the electrostatically charged media are high-quality. The filter includes a foam gasket to ensure a tight seal, a detail often overlooked by cheaper counterparts. Users report fitting their return air vent and shutting the door with ease, eliminating the need for additional tape.
One small trade-off is the housing material: the paper-based housing is thinner than the original OEM Trion filter, which some might consider less sturdy. For everyday residential use, this is likely not a performance issue, but those seeking the exact same heft as the brand filter may take note. There are no other significant drawbacks based on customer feedback.
Overall, the AIRx Filters 16x25x5 MERV 8 2-Pack offers excellent value, a perfect fit, and US-made quality. It's a cost-effective solution that doesn't compromise on filtration performance. If you're in the market for a replacement that fits, works, and protects your HVAC system, this is a strong contender.

Buying Guide
MERV Rating Matters Most
The Minimum Efficiency Reporting Value (MERV) tells you how well a filter captures airborne particles. For most homes, MERV 8 captures lint and dust mites, MERV 11 traps pollen and mold spores, and MERV 13 stops smoke and bacteria. Our list includes filters from MERV 8 up to MERV 16, so you can match the level to your family’s needs without overworking your HVAC system.
If you have allergy concerns, consider a MERV 11 or higher. The top 20 x 25 x 1 furnace filters for cleaner air guide also covers similar choices for different filter thicknesses.
Fit and Compatibility
Not all 16x25x5 filters have identical actual dimensions. Some measure 15.75 x 24.75 x 4.31 inches, while others are slightly larger. Always check your HVAC cabinet’s clearance and compare the actual size listed by the manufacturer. Many of our picks, like those from AIRx Filters, are compatible with common systems from Bryant, Carrier, Honeywell, and Lennox.
Build Quality and Longevity
A well-constructed filter uses moisture-resistant frames and electrostatically charged media to maintain efficiency. Filters that are 100% made in the USA, as many AIRx Filters are, often have stronger corrugated beverage board frames. Higher MERV filters may need replacement every three to six months, while premium options like the Lennox X6672 can last up to one year under normal conditions.
Special Features
Some filters come with carbon coating for odor removal or include reminder magnets. The Lennox X6672 Carbon Clean filter combines MERV 16 filtration with activated carbon to tackle volatile organic compounds. Others offer multi-packs for convenience. Decide whether you value odor control, ease of installation, or extended life when making your choice.
Final Thoughts
After reviewing ten impressive filters, we recommend the AIRx Filters 16x25x5 Furnace & AC Filter MERV 8 for budget-friendly, reliable performance that fits many standard systems, and the Lennox X6672 16x25x5 Healthy Climate Carbon-Clean for those who want the highest filtration combined with odor removal and a year-long lifespan. Whichever you choose, swapping your old filter for a fresh one will immediately improve your indoor air quality and protect your HVAC equipment.
Frequently Asked Questions
How often should I replace a 16x25x5 furnace filter?
Generally, every three months for MERV 8, every two to three months for MERV 11, and every six to twelve months for MERV 13 or higher. Check your filter every month and replace it when it looks dirty.
Can I use a MERV 16 filter in my standard HVAC system?
Most residential systems can handle MERV 16, but high-efficiency filters may restrict airflow if your blower is not powerful enough. Consult your HVAC manual or a professional before upgrading to a MERV 13 or higher.
Are AIRx Filters compatible with Menards furnace filter sizes?
Yes, the nominal 16x25x5 size matches what you would buy at Menards. The actual dimensions (around 15.75 x 24.75 x 4.38 inches) fit most standard cabinets. Always measure your slot before ordering.
What does MERV 8 mean compared to MERV 11?
MERV 8 captures particles 3 to 10 microns (lint, dust mites), while MERV 11 captures particles 1 to 3 microns (pollen, mold spores). For better allergy protection, choose MERV 11 or higher.
