Whirlpool Heat Pump Dryer Tertiary Filter available

A homeowner is giving away a homemade filter he built for the full-size Whirlpool Heat Pump Dryer (model WHD560CHW2), free except for shipping. He posted it in an online forum thread and asked interested readers to contact him to work out details. This isn't a company recall or product launch, just one person passing along a DIY part he no longer needs.

The backstory is more useful than the filter itself. He bought the Whirlpool heat pump dryer in early 2022. A heat pump dryer works like a heat pump air conditioner in reverse, recycling heat to dry clothes with less energy than a standard electric dryer. After about 35 months, drying times had slowed way down. He found a forum thread describing the same problem, opened the dryer to clean the coils, and also built a "tertiary filter," an extra lint filter beyond the machine's built-in ones, to catch lint the factory filters were missing. Neither fix solved it, and the heat pump function eventually failed. He couldn't find a repair company that even knew what a heat pump dryer was, so in March 2025 he replaced it with a full-size LG heat pump dryer.

He reports the LG cost less, has an interior light, and filters lint much better. After 18 months, its coil is nearly free of lint buildup, unlike the Whirlpool. If you own the same Whirlpool model, or are shopping for a heat pump dryer, this is one owner's real-world experience worth knowing before you buy or troubleshoot slow drying times.
