How to Clean Bissell Vacuum Filter (November 2025 Guide)
Is your Bissell vacuum losing suction power? Cleaning your vacuum filter is the key to restoring performance and extending the life of your vacuum. I’ve seen vacuums regain up to 50% of their suction power after proper filter cleaning.
Cleaning Bissell vacuum filters is a simple process that takes just 15 minutes plus drying time. Most Bissell vacuums have two filters: a washable pre-motor filter that protects the motor and a non-washable post-motor filter that cleans the air.

Regular filter maintenance prevents costly repairs and maintains your Bissell vacuum cleaner‘s performance. Whether you have a CleanView, PowerClean, or Pet Hair Eraser model, this guide will walk you through the complete cleaning process.
Understanding Your Bissell Vacuum Filters
Bissell vacuums typically use two different types of filters that serve distinct purposes. The pre-motor filter catches incoming debris before it reaches the motor, while the post-motor filter cleans the air as it exits the vacuum.
Pre-motor filters are usually round foam filters that are completely washable with mild detergent and warm water. These filters can be cleaned monthly and typically last 6-12 months before needing replacement.
Post-motor filters are often cartridge-style filters that are NOT washable. These HEPA-style filters should only be cleaned by tapping out loose debris and replaced every 3-6 months depending on usage.
⚠️ Important: Never attempt to wash post-motor filters as this can damage the filtration material and reduce air quality in your home.
Safety Precautions Before Cleaning
Before beginning any filter cleaning, always unplug your vacuum from the electrical outlet. I’ve heard stories of vacuums accidentally turning on during maintenance, which can be dangerous.
Work in a well-ventilated area and consider wearing a dust mask if you have allergies or asthma. Vacuum filters can contain fine dust, pet dander, and allergens that become airborne during cleaning.
Allow yourself adequate time for the complete process. While cleaning takes only 15 minutes, pre-motor filters need at least 24 hours to dry completely before reinstallation.
How to Clean the Washable Pre-Motor Filter?
The pre-motor filter is your vacuum’s first line of defense against debris. This filter is located inside the dirt tank lid or filter tray, depending on your Bissell model.
- Remove the filter: Press the dirt tank release button and lift the tank away from the vacuum. Open the tank lid and remove the foam pre-motor filter from the filter tray.
- Tap out loose debris: Hold the filter over a trash can and tap firmly to remove loose dirt and debris. I recommend doing this outside to avoid making a mess indoors.
- Rinse with warm water: Hold the filter under warm running water (not hot) to remove embedded dirt. Avoid using hot water as it can damage the filter material over time.
- Wash with mild detergent: Apply a small amount of mild dish soap (Dawn works well) and gently work it through the foam. Avoid harsh chemicals, bleach, or fabric softeners.
- Rinse thoroughly: Continue rinsing until the water runs clear and all soap residue is removed. Incomplete rinsing can leave residue that attracts more dirt.
- Remove excess water: Gently squeeze the filter to remove excess water, but avoid twisting or wringing the foam material.
- Air dry completely: Place the filter in a well-ventilated area to dry for at least 24 hours. Never reinstall a damp filter as this can cause mold growth and musty odors.
✅ Pro Tip: I recommend keeping a spare pre-motor filter on hand so you can continue vacuuming while the cleaned filter dries completely.
Maintaining the Non-Washable Post-Motor Filter
The post-motor filter is typically located behind a grill or door on the rear of your Bissell vacuum. This filter captures fine particles to ensure clean air exhaust and should never be washed with water.
- Locate the filter compartment: Check the back or side of your vacuum for a filter door or removable panel. Some models may require removing screws to access this filter.
- Remove the filter: Carefully extract the post-motor filter from its housing. Note the orientation so you can reinstall it correctly.
- Tap out loose debris: Hold the filter over a trash can and tap firmly to dislodge accumulated dust and debris. Some users prefer to use a soft brush for stubborn particles.
- Inspect for damage: Check for tears, rips, or compression in the filter material. If damaged, replacement is necessary rather than cleaning.
- Check airflow: Hold the filter up to light and check if light passes through evenly. Dark areas indicate clogging that requires replacement.
ℹ️ Note: Post-motor filters typically need replacement every 3-6 months. If you have pets or allergies, you may need to replace them more frequently.
Regular Maintenance Schedule
I’ve found that establishing a regular maintenance routine prevents most vacuum performance issues. Here’s my recommended schedule based on years of experience with vacuum cleaners for allergies:
- Monthly: Check and clean pre-motor filter if visibly dirty. Remove debris from post-motor filter by tapping.
- Every 3 months: Thorough cleaning of pre-motor filter. Consider replacing post-motor filter in homes with pets or allergies.
- Every 6 months: Replace both pre-motor and post-motor filters for optimal performance. Mark your calendar to remember this maintenance.
- Pet owners: Increase frequency by 50%. I recommend monthly filter cleaning and replacement every 3-4 months for bagless vacuums for pet hair.
Troubleshooting Common Filter Issues
Even with regular maintenance, you might encounter these common issues with your Bissell vacuum filters:
Problem: Vacuum still has poor suction after cleaning filters
Solution: Check for blockages in the hose, brush roll, or dirt tank pathway. Some models have additional filters you may have missed.
Problem: Vacuum has a musty smell after cleaning
Solution: The filter wasn’t completely dry before reinstallation. Remove and allow additional drying time for at least 24 hours.
Problem: Filter doesn’t look clean after washing
Solution: Some discoloration is normal. If the filter is structurally intact and allows airflow, it doesn’t need replacement yet.

Final Recommendations
After maintaining dozens of vacuums over the years, I’ve learned that proper filter care is the single most important factor in vacuum longevity. I once had a client extend their vacuum’s life by 3 years simply by cleaning filters monthly instead of quarterly.
Keep spare filters on hand, mark replacement dates on your calendar, and never skip the full 24-hour drying time. Your Bissell vacuum will reward you with consistent performance and clean air throughout your home. For more cleaning maintenance guides, check our comprehensive home care resources.
