PVDF (polyvinylidene fluoride) washable filters are high-precision, durable, and reusable water filtration units, often using 0.01-micron hollow fiber membranes to remove bacteria, sediment, and heavy metals. Designed for long life, these filters can be hand-washed, allowing for 100+ cleanings or up to 5 years of service, making them cost-effective alternatives to disposable cartridges.
