Honeywell

This page carries Tier1 water panels in the Aprilaire #10 and #35 sizes for whole-house humidifiers, sold in 2-packs. Check the size and part number of the current pad in your Honeywell unit before ordering. Aprilaire recommends replacing these panels once a year.

How to check fit

To check whether a Tier1 panel fits your Honeywell humidifier, compare your current pad with the #10 and #35 sizes.

• Read the part number on your current pad.
• Measure its dimensions.
• Compare both with the #10 and #35 product pages. The #10 fits Aprilaire 110, 220 and 500 series humidifiers, and the #35 fits Aprilaire 600 and 700 series humidifiers.

Common questions

Which filter does my Honeywell whole-house humidifier need?

Your Honeywell whole-house humidifier needs a pad that matches its current one. The Tier1 #10 and #35 panels fit only if your Honeywell unit, such as an HE360 or HE260, takes the same size pad, so compare dimensions and part number first.

How often should you replace a humidifier water panel?

Aprilaire recommends replacing #10 and #35 water panels once a year. For other sizes, browse all humidifier water panels, or shop Honeywell air filters.
