Keeping your Shark vacuum running at its best starts with knowing how to clean Shark vacuum filters. A clean filter is the heart of your vacuum’s suction power, and neglecting it can lead to poor performance and even damage. This guide will walk you through every step for all common Shark filter types, making maintenance simple and effective.
You’ll learn the right way to clean each filter, how often you should do it, and crucial mistakes to avoid. Let’s get started and ensure your vacuum keeps working like new.
How to Clean Shark Vacuum Filters
This main process covers the universal steps for cleaning the most common washable filters found in Shark vacuums. Always check your specific model’s manual first, as instructions can vary slightly.
What You’ll Need
- Cool, clean tap water
- A sink or large bowl
- Mild dish soap (optional)
- A clean, dry towel
- A well-ventilated area for drying
Step-by-Step Cleaning Instructions
1. Remove the Filters Safely
First, unplug your vacuum. Locate and remove the dust cup or bin. Open it and take out the pre-motor filter (usually a flat foam or felt piece). Then, find the post-motor or HEPA filter. This is often a pleated, rectangular filter located near the vacuum’s exhaust.
2. Tap Out Loose Debris
Over a trash can, gently tap each filter to dislodge any loose dust and hair. Avoid banging them hard, as this can damage the filter material. For foam filters, you can gently stretch and flex them to help debris fall out.
3. Rinse With Cool Water
Hold each filter under a stream of cool, running water. Rinse thoroughly until the water runs clear. For the foam filter, gently squeeze and release it under the water to wash away embedded dirt. Never use hot water, as it can warp or shrink some filter materials.
4. Use Soap for Stubborn Dirt (If Needed)
If filters are very dirty, you can use a drop of mild dish soap. Lather it gently in your hands and rinse completely. Any soap residue left behind can attract more dirt later or cause clogs.
5. The Most Important Step: Dry Completely
This is where many people go wrong. Filters must be 100% dry before reinstalling. Gently press water out of foam filters with a towel. Do not twist or wring them. Place all filters in a well-ventilated area, away from direct sunlight or heat sources. Allow them to air dry for at least 24 hours. This can take up to 48 hours for thicker HEPA filters. Never use a hairdryer or put them back in the vacuum damp.
Cleaning Specific Shark Filter Types
Different Shark models use different filter combinations. Here’s how to handle the main types.
Foam and Felt (Pre-Motor) Filters
These protect the vacuum’s motor from large debris. They’re usually the first filter in the assembly. Clean them every 1-3 months, or more often if you vacuum fine dust like pet hair or baking flour. The foam ones are very durable but be gentle when squeezing them during rinsing.
HEPA (Post-Motor) Filters
These fine filters trap microscopic particles. They are not all washable. Check your manual—if it’s labeled “washable” or “permanent,” you can rinse it. If it’s not, you must replace it. For washable HEPA filters, rinse carefully under cool water, holding the pleats open. Let them dry for a full 48 hours to prevent mold.
Anti-Allergen Complete Seal Filters
Common in many Shark uprights, this system often includes both a felt and a HEPA filter. Both are typically washable. Follow the general steps above, paying extra attention to drying the dense HEPA filter completely. A good tip is to set it near a fan to circulate air.
How Often Should You Clean Shark Filters?
- Pre-motor (foam/felt) filters: Every 1-3 months.
- Post-motor (HEPA) filters: Every 3-6 months.
- For heavy use or pets: Clean all filters monthly.
- Always check your manual for the manufacturer’s specific recommendation for your model.
Common Mistakes to Avoid
- Not drying filters fully: This is the top cause of mold, mildew, and poor suction. It can even damage your vacuum motor.
- Using hot water: Hot water can melt adhesives or distort filter shapes.
- Brushing or scrubbing: This can tear the delicate filter material, especially on HEPA filters.
- Using harsh chemicals: Bleach or strong cleaners will degrade the filter material.
- Putting filters in the dishwasher or washing machine: The agitation and heat are too harsh.
When to Replace Your Shark Filters Instead of Cleaning
Even washable filters don’t last forever. You need to replace them if you notice any of the following signs:
- Visible tears, holes, or permanent discoloration.
- A lingering odor even after thorough washing and drying.
- Reduced suction power even after cleaning the filters and checking for blockages.
- Your vacuum’s “check filter” light stays on after proper cleaning.
- Non-washable filters should be replaced every 12-18 months with regular use.
Keeping Your Entire Vacuum Clean
For optimal performance, filter cleaning should be part of a broader maintenance routine.
Empty the Dust Cup Regularly
Don’t let it fill past the “Max” line. Empty it after every few uses, especially if you’re picking up fine dust. This prevents debris from prematurely clogging your filters.
Check for Blockages
If suction is low, check the hose, wand, and nozzle for clogs. A common spot is where the hose connects to the dust cup. Detach these parts and look through them for obstructions.
Clean the Brush Roll
Regularly cut away hair and strings wrapped around the brush roll. A clogged brush roll strains the motor and reduces cleaning effectiveness on floors.
Troubleshooting Filter-Related Problems
Vacuum Has Weak Suction
First, ensure the filters are clean and completely dry. Then, check for blockages in the hose and nozzles. Make sure all parts, including the filters, are correctly reseated after cleaning. A misaligned filter door can also cause a loss of suction.
A Strange Smell is Coming From the Vacuum
This usually indicates a damp or moldy filter. Remove and inspect all filters. If they smell musty after drying, they likely need to be replaced. Also, empty and wash the dust cup with mild soap, as odor-causing debris can stick to it’s walls.
The “Check Filter” Light is On
This sensor monitors airflow. The light means airflow is restricted. Turn off and unplug the vacuum, then check and empty the dust cup. Next, remove and inspect the filters. Clean them if dirty, and ensure they are 100% dry before putting them back in. Also clear any hose or nozzle blockages.
FAQ Section
Can you wash all Shark vacuum filters?
Not all. Most Shark pre-motor (foam/felt) filters are washable. Many, but not all, post-motor HEPA filters are also washable. You must check your user manual to be certain. Non-washable filters will be clearly labeled and should only be replaced.
How long do Shark filters take to dry?
Drying times vary. Thin foam filters may dry in 6-12 hours. Dense felt and pleated HEPA filters need a minimum of 24 hours, and often up to 48 hours, to dry all the way through. Never rush this process.
What happens if you don’t clean your Shark vacuum filter?
Neglecting filter cleaning leads to a rapid drop in suction power. It forces the motor to work harder, which can overheat and potentially burn it out. It also reduces air quality by recirculating dust back into your home and can cause unpleasant odors.
Can I use my Shark vacuum without a filter?
No, you should never run your Shark vacuum without its filters installed. The pre-motor filter is critical for protecting the motor from dust and debris. Running it without filters will almost certainly cause permanent and costly damage to the vacuum’s motor.
Where can I buy replacement filters for my Shark vacuum?
Genuine Shark replacement filters are available on the Shark website, through authorized retailers like Amazon, and at major appliance stores. Always use your exact model number (found on the vacuum’s rating plate) to order the correct filters. Using off-brand filters can sometimes affect performance.
Regular filter maintenance is the simplest way to extend the life of your Shark vacuum and keep it performing powerfully. By following these clear steps—especially the crucial drying time—you’ll avoid common problems and ensure your vacuum is always ready for a cleaning session. Set a calendar reminder every few months to check your filters, and you’ll save time and money in the long run.
