UpStart Battery Linx Foam Filter

For optimal suction, we recommend rinsing the filter under cold water every 2 to 4 weeks, depending on how frequently you vacuum. Always ensure the filter is completely air-dried for at least 24 hours before reinstalling it to prevent mold or motor damage.

These filters are engineered to be compatible with the Hoover Linx series, including models SH20030, BH50010, BH50030, CH20110, BH50010W, BH50015, and BH50010CA. Please double-check your vacuum's model number against this list before purchasing to ensure a precise fit.

While the filters are washable, they eventually degrade over time and lose their ability to trap fine dust effectively. Having a five-pack allows you to rotate filters while one is drying, and provides convenient replacements for when the foam begins to break down or retain odors.

This is a standard foam filter designed primarily to capture dust and debris to protect your vacuum's motor. While it will catch larger particles, it is not a HEPA-rated filter and is not specifically designed to trap fine allergens or microscopic particulates.

You should replace the filter if you notice the foam is tearing, crumbling, or if the suction power remains weak even after a thorough cleaning and drying. If the filter looks discolored or retains a musty smell even after washing, it is time to swap it for a fresh one from the pack.
