Carrier Humidifier Pad Replacement Review
Air Filter Factory HUMCCLBP Replacement Pad
ADVANTAGES
LIMITATIONS
This U.S.-made powerhouse delivers unmatched durability and consistent performance for homeowners tired of flimsy, short-lived humidifier pads. Engineered with a heavy-duty aluminum backing and a porous ceramic-type coating, the Air Filter Factory replacement pad maintains its shape over time while optimizing water absorption—critical for efficient evaporation during furnace cycles. Its rugged build directly tackles the common pain point of panel warping, which can create air gaps and reduce humidity output in whole-house systems.
In real-world use, this pad excels in standard Carrier and Bryant models like the 2217 and 2317, where precise fitment is non-negotiable. Measuring 10” x 13” x 1-5/8”, it slides seamlessly into compatible units without trimming, ensuring immediate operation post-install. The material’s high wicking capacity sustains steady moisture release across heating seasons, especially in dry climates or older homes with inconsistent indoor humidity. However, it may slightly underperform in high-mineral water areas if not paired with regular maintenance, as the ceramic surface can gradually scale over time.
When stacked against the HASME P110-3545 model, this pad offers superior structural integrity but lacks compatibility with newer frameless designs that demand exact thickness tolerance. It’s ideal for DIYers who prioritize longevity and American craftsmanship over ultra-broad compatibility. For those maintaining older Bryant or Carrier units, this filter provides a perfect balance of durability, fit, and evaporation efficiency—outperforming thinner imports while costing less than premium aftermarket alternatives.

Step into next-level humidification with the P110-4545 wick pad, a precision-engineered solution built for Carrier and Bryant’s wide-flow humidifier series. What sets this pad apart is its dual-layer aluminum foil construction, which not only boosts structural rigidity but dramatically increases the surface area for water vapor dispersion—translating to faster, more effective room humidification. Designed specifically for models like HUMCCWBP2417 and HUMBBWBP2417, it solves the chronic issue of uneven moisture distribution by promoting a uniform wicking action across the entire panel.
During extended heating cycles, this pad consistently delivers strong humidity output, thanks to its honeycomb matrix that filters out sediment and minimizes mineral clog buildup—extending both pad life and system efficiency. At 12.59 × 9.44 × 1.57 inches, it fits snugly into its target units without modification, making installation a true tool-free, five-second swap. It performs exceptionally well in homes with moderate water hardness, though users in high-mineral areas should still plan for seasonal replacements to maintain peak output.
Compared to the GULUANT P110-1045, this model offers far better water dispersion and durability, though it comes at a higher cost. It’s the go-to choice for homeowners with wide-flow Carrier units who demand maximum output and long-term reliability. While not as universally compatible as some alternatives, its targeted design outshines generic pads in both performance and filtration—making it the smart pick for those who want their humidifier to run like new.

ADVANTAGES
LIMITATIONS
Don’t let the modest specs fool you—this budget-savvy GULUANT pad punches well above its weight for homeowners seeking reliable, no-frills performance. Designed for P110-1045-compatible units, it’s a perfect match for compact Carrier, Bryant, and Payne humidifiers where space and fit are tight. Its 9-1/2” x 10” x 1-1/2” dimensions ensure a clean slide-in replacement, eliminating the need for trimming or guesswork—ideal for renters or first-time maintainers who want hassle-free upkeep.
In practice, the pad holds up reasonably well over a single heating season, effectively wicking water and releasing steady humidity in small to mid-sized homes. While it lacks advanced features like aluminum reinforcement or honeycomb filtration, it does a solid job of trapping mineral deposits, helping slow down scale buildup in the humidifier tray. However, it’s best suited for low-to-moderate usage environments; in high-demand settings or homes with very dry air, it can struggle to keep up due to its thinner, less absorbent core.
When compared to the HASME P110-3545, it’s clearly a step down in durability and coverage, but it shines as the most cost-effective 2-pack in the lineup. It’s the ideal pick for those who need a dependable, short-term solution without overspending—especially when servicing older, less powerful systems. For basic humidity needs and easy maintenance, this pad delivers solid value without surprises.

Meet the precision aftermarket contender that redefines fit and function for Carrier’s most common humidifier models. The HASME P110-3545 replacement pad is engineered to mirror OEM specifications with exacting detail—measuring 10 1/8” x 12 7/8” x 1-1/2”—ensuring a seamless drop-in experience for popular units like HUMCCLBP2417 and HUMCALBP2317. This isn’t just another generic pad; it’s built for users who refuse to compromise on compatibility and consistency, especially when replacing hard-to-find originals.
Real-world testing shows it performs reliably across full heating seasons, maintaining strong wicking action and resisting deformation even under continuous use. Its dense fiberglass matrix effectively absorbs water and resists channeling—a common flaw in cheaper pads that leads to uneven evaporation. While it doesn’t feature aluminum backing or advanced filtration layers, its uniform porosity ensures steady humidity output and reduces the risk of dry air pockets in larger homes.
Stacked against the Air Filter Factory model, it offers nearly identical dimensions and compatibility but at a steeper price point, making it better suited for those who prioritize exact OEM replacement over added durability. It’s the top choice for homeowners with P110-3545-dependent systems who want peace of mind and hassle-free maintenance. Though pricier than budget options, it delivers superior consistency and fit—making it worth the investment for long-term system health.
Choosing the Right Carrier Humidifier Pad Replacement
Understanding Pad Types & Materials
Carrier humidifier pads are essential for maintaining healthy humidity levels in your home, especially during dry winter months. When it’s time for a replacement, understanding the different types and materials available will help you choose the best option for your needs. The core function of these pads is to provide a large surface area for water to evaporate as air from your furnace blows across them. The most common materials are cellulose and aluminum foil. Cellulose pads are generally more affordable but require more frequent replacement. Aluminum foil pads, like those found in the P110-4545 model, are more durable and offer superior water absorption, potentially lasting longer and providing more efficient humidification.
Size and Compatibility – A Critical Consideration
Perhaps the most important factor is ensuring the replacement pad is the correct size and compatible with your specific Carrier humidifier model. Pads come in various dimensions (e.g., 10″ x 9.75″ x 1.75″ for P110-1045, or 12.59″ x 9.44″ x 1.57″ for P110-4545). Always verify the part number of your existing pad before purchasing a replacement. Many pads are designed as direct replacements for specific Carrier/Bryant model numbers (like the HASME pad for P110-3545). Using the wrong size will reduce efficiency and could damage your humidifier. Some products, like the Air Filter Factory HUMCCLBP, provide multiple compatible model numbers.
Durability and Lifespan
The lifespan of a humidifier pad depends on several factors, including water quality, usage frequency, and the pad’s material. Aluminum foil pads (like P110-1045) generally offer greater durability than cellulose options. Look for pads described as having “high durability and quality construction,” as seen in the Bryant/Carrier P110-3545 description. Consider the replacement frequency when evaluating cost—a more expensive, longer-lasting pad might be more economical in the long run. Regularly check your pad for mineral buildup or signs of deterioration, and replace it as needed (typically every 6-12 months, but more often if you have hard water).
Pack Size & Value
Humidifier pads are often sold individually or in multi-packs. If you want to save money and have a spare on hand, a 2-pack (like the GULUANT P110-1045 or P110-4545) can be a good value. Consider your usage patterns and storage space when deciding on a pack size. Having a replacement readily available ensures you won’t have to deal with dry air for an extended period.
U.S. Made Quality
For some buyers, the origin of the product is important. Options like the Air Filter Factory HUMCCLBP highlight that they are proudly made in the USA, which can be a sign of higher quality control and manufacturing standards.
