This genuine AprilAire replacement water panel humidifier filter features a porous ceramic-type coating that absorbs water and maintains the proper level of hydration to support the evaporation process. Water is vaporized as air warmed by the furnace passes over the water panel humidifier filter carrying humidified air throughout the house through the air ducts. AprilAire has been there since the beginning by introducing the first whole-home humidifier in 1954. Since then, we've continued to focus on quality design, engineering, and manufacturing to deliver Healthy Humidity to every home. Healthy Humidity reduces the incidence and risk of respiratory infections from airborne viruses. It also helps remedy your dry skin, chronic sore throat, frequent nosebleeds, and static shock. Additionally, proper humidity levels protect your home's wood furnishings from cracking or splitting while lowering your energy bill. Keep your AprilAire Humidifier running at peak performance by replacing your water panel annually. The Model #35 Water Panel dimensions are 10" W x 13" H x 1.75" D and illustrated instructions help you change your water panel quickly and efficiently.

These fit our AprilAire whole house humidifier system, they're easy to install, and we only need to replace them once per winter season, so the price is right and nothing works as well as original brand equipment.

These water panels fit my Aprilaire humidifer perfectly and seem to provide the most efficient water to water vapor conversion of any panel because they increase the humidity faster than the other brands.

I’ve been using the Aprilaire 35 Water Panel Humidifier Filters for years now, and they’ve never let me down. These filters are an exact fit for my Aprilaire 600 model, and the installation process is straightforward, no tools required. The filters are well-made, and you can tell they’re built to last.One thing I’ve learned over the years is to replace them at the start of each winter season. If you live in a cold, dry climate like I do, this will make a noticeable difference in keeping your home comfortable. The air feels fresher, and it really helps with dry skin and static electricity.The 2 pack is a nice bonus because it saves me from running out mid-season, and it’s cost-effective. I also appreciate that these are genuine Aprilaire parts, made in the USA.My tip? Mark your calendar as a reminder to replace it every year. It’s one of those small maintenance tasks that can really pay off when it comes to indoor air quality.

The box comes with all the detail instructions needed to install. I felt very confident after reading and was able to perform on my own device. I ordered the 10 pack which gives the most value for my money. In addition, it gives me the peace of mind not having to buy more filters down the road. The filter feels good quality, and looks identical to the default one already installed for my home.

Good product, but the thickness is 1.5" not 1.75", 1.5" is the right size to fit in the filter frame.

The panel came as expected and was made of metal. So 2 pack will last me 2 years unlike the other paper material panels that you have to replace every few months. Panel fit perfect and works well.
