This listing targets the HC-888 model string, specifically for Honeywell and Walgreens units, which is the exact code you need to match against the label on your existing wick. The 4.9-star rating suggests a tight fit, but the title does not specify a pack size, so you are buying a single replacement unit.

In the product photo, look for the specific ribbed texture and the exact dimensions of the wick, as this is a direct fit for the HC-888. If your current pad is thicker or has a different core structure, this will not seat correctly in the tray, leading to water bypass and dry air.

The title explicitly lists compatibility with AprilAire models 300, 350, 360, 560, 560A, 568, and 600, identifying this as the 35-series panel. This is a single unit replacement, not a multi-pack, so the price reflects one wick for your whole-house system.

Check the photo for the specific depth of the wick; the 35-series is distinct from the 10 or 45 series in thickness. If you are replacing a 45-series pad, this 35 will be too thin, causing the water level to drop below the wick and the unit to run dry.

This is the 10-series panel, compatible with AprilAire models 110, 220, 500, 500A, 500M, 550, and 550A. The '10' designation refers to the wick depth, which is thinner than the 35 or 45 series, and it is sold as a single unit.

In the listing image, verify the width of the wick against your current pad. The 10-series is designed for specific AprilAire housings; if your unit requires a 35 or 45, this wick will be too narrow, leaving gaps that allow water to bypass the evaporative surface.

The title identifies this as a Honeywell Home whole-house humidifier pad, but it does not list specific model numbers in the headline, relying on the brand and type. This is a single replacement wick for your forced-air system.

Look at the photo to confirm the ribbed pattern and the overall shape. Honeywell pads have a specific core density; if your unit is a different brand or a different Honeywell series, the dimensions will not align, causing the pad to shift in the tray and fail to absorb water efficiently.

This listing is a 2-pack of Generalaire 990-13 water pads, which is a cost-effective option if you need to replace both sides of your humidifier or want a spare on hand. The '990-13' is the specific part number you must match.

In the product photo, check the thickness of the wick. The 990-13 is a standard depth, but if your unit requires a different Generalaire model number, this pad will not fit the tray correctly, leading to water leakage and reduced humidity output.

This is a 2-pack of AprilAire 45-series panels, compatible with models 400, 400A, and 400M. The '45' indicates a thicker wick than the 10 or 35 series, and you are getting two units for the price.

Verify the depth in the photo; the 45-series is the thickest of the AprilAire lineup. If your unit is designed for a 35-series pad, this 45 will be too thick to fit in the tray, preventing the water from reaching the top of the wick and causing the unit to run dry.

The title specifies compatibility with GeneralAire 900 and 1000 humidifiers, referencing GFI #7919. This is a single wick replacement for those specific models, and the 'GA900' designation is the key identifier.

Look at the photo for the specific shape and ribbing of the wick. The GA900 pad has a unique profile; if your unit is a different GeneralAire model, this pad will not seat properly, causing water to bypass the wick and the unit to fail to add moisture to the air.

This is the Generalaire 1099-20 evaporative water pad, a single unit replacement. The '1099-20' is the specific part number that must match your current wick to ensure a proper fit.

In the listing image, check the width and depth of the wick. The 1099-20 is a standard size for many Generalaire units, but if your unit requires a different model number, this pad will not fit the tray, leading to water leakage and reduced humidity output.

The title identifies this as the AIRCARE 1041 Super Wick, a single unit replacement. The '1041' is the specific model number, and 'Super Wick' suggests a higher capacity or density than standard wicks.

Look at the photo for the specific ribbing and core structure. The 1041 is designed for specific AIRCARE units; if your unit is a different model, this wick will not fit the tray correctly, causing water to bypass the wick and the unit to fail to add moisture to the air.

This is a 2-pack of replacement pads for Bryant and Carrier humidifiers, compatible with models HUMCCLBP, HUMBBSBP, 2217, 2317, 2417, and HUMBALBP. You are getting two wicks for the price, which is a cost-effective option for whole-house systems.

In the product photo, verify the specific shape and ribbing of the wick. The Bryant/Carrier pads have a unique profile; if your unit is a different brand or model, this pad will not seat properly, causing water to bypass the wick and the unit to fail to add moisture to the air.
