How To Wash Dyson Vacuum Filter

Knowing how to wash Dyson vacuum filter is essential for keeping your machine running at its best. A clean filter is the heart of your vacuum’s suction power, and washing it regularly is a simple task that can save you money and hassle. This guide will walk you through the entire process, step-by-step, for all common Dyson filter types.

We’ll cover everything from identifying your filter to the crucial drying steps many people miss. Let’s get started.

This is the core process for washing the main post-motor HEPA or carbon filter found in most Dyson cordless, upright, and canister models. Always check your user manual first for model-specific instructions, as the steps can vary slightly.

What You’ll Need

Cool tap water
A clean sink or bowl
Your hands (no brushes or tools)
A dry, well-ventilated place to dry for 24+ hours

Step-by-Step Washing Instructions

Step 1: Remove the Filter

First, make sure your vacuum is turned off and unplugged. For cordless models, remove the battery. Locate the filter compartment—it’s often on the top, back, or near the bin. Twist or pull the filter gently to release it from its housing.

Step 2: Tap Out Loose Dust

Take the filter outside or over a trash bin. Gently tap it against the side to dislodge any loose, dry dirt and debris. This preliminary step helps prevent clogging your sink with fine dust.

Step 3: Rinse Under Cool Running Water

Hold the filter under a gentle stream of cool tap water. Rinse the outside of the filter first, letting the water flow through the pleats or foam. Never use hot water, as it can damage the filter material and potentially warp the plastic casing.

Step 4: Wash Until Water Runs Clear

Continue rinsing, occasionally turning the filter to wash it from different angles. You may gently squeeze the pleated filter or press on foam filters to help water flow through. Do not twist or wring it aggressively. Keep washing until the water running out from the filter is completely clear.

Step 5: The Crucial Drying Step

This is the most important part. Gently shake off excess water. Place the filter in a dry, well-ventilated area away from direct heat, sunlight, or radiators. It must air dry naturally for at least 24 hours. Drying it completely usually takes a full 48 hours. Never put the filter back in the vacuum while it’s even slightly damp.

Common Mistakes to Avoid

Using Soap or Detergent: This can damage the filter’s material and leave a residue that affects performance and odor.
Using Hot Water: Hot water can shrink or warp filter components, ruining the seal.
Incomplete Drying: A damp filter will cause your vacuum to lose suction and can trigger safety shut-offs. It can also lead to mold and mildew.
Using Tools or Brushes: Scrubbing can tear the fine material. Your hands and water are all you need.

How to Wash Different Types of Dyson Filters

Not all Dyson filters are washed the same way. Here’s a breakdown for the main types you might encounter.

Pleated HEPA/Carbon Filters (Most Common)

These are the blue or purple pleated filters found in models like the V-series, Outsize, Cyclone V10/V11/V15, and many uprights. Follow the standard washing procedure above. Be extra patient with drying, as the many pleats hold a lot of water.

Pre-Motor Foam Filters (Older Upright Models)

Some older Dyson models, like the DC07 or DC14, have a pre-motor foam filter. This is usually a thick, yellow foam sleeve. Remove it and rinse it thoroughly under cool water until the water runs clear and the foam returns to its original color. Squeeze it gently—don’t twist—and let it dry for 24 hours completely before reinstalling.

Combined Filter Units (Some Cordless Models)

Models like the V7 or V8 sometimes have a filter that combines the HEPA media with a plastic housing. You wash the whole unit. Just be sure no water gets trapped inside the plastic cavity. Shake it thoroughly after washing and point the opening downward while drying.

How Often Should You Wash Your Dyson Filter?

Dyson recommends washing your filter at least once every month under normal use. However, your frequency depends on a few factors:

Usage: Vacuuming daily or in a pet-heavy home? Wash it every 2-3 weeks.
Environment: Lots of dust or fine debris (like construction dust or ash) means more frequent washing.
Vacuum Performance: If you notice a drop in suction, it’s a clear sign the filter needs attention.

Setting a monthly calendar reminder is a great way to remember this important maintence task.

What to Do If Your Vacuum Still Has Low Suction After Washing

If you’ve washed and fully dried the filter but your vacuum isn’t performing well, don’t panic. Try these troubleshooting steps:

Double-Check Drying: Is the filter 100% bone-dry? Even slight dampness is a common culprit. Give it another 12 hours in a warm, dry room.
Inspect for Blockages: Suction loss is often caused by a clog elsewhere. Check the hose, wand, brush bar, and all openings for trapped debris. A common blockage point is where the bin connects to the cyclone.
Check the Bin Seal: Ensure the clear bin is clicked securely into place and the seals are clean. A poor seal breaks the vacuum’s airflow.
Consider Filter Replacement: Filters don’t last forever. Even with proper washing, they wear out. If your filter is over 2-3 years old or appears damaged, it’s probably time for a new one.

How to Properly Dry Your Dyson Filter

We can’t stress this enough: drying is key. Here are the best practices to ensure it dries correctly:

Location: Choose a warm, dry room with good air circulation. A laundry room or spare bedroom is often perfect.
Position: Stand the filter upright on its end, if possible, to allow water to drain from the bottom. For pleated filters, you can alternate between standing it up and laying it on its side every few hours.
What to Avoid: Never use a hairdryer, oven, microwave, or place it on a heater. Avoid direct sunlight, which can degrade the materials. Do not cover it with a towel, as this traps moisture.

Patience is your best tool here. Rushing this step will only lead to frustation later.

When to Replace Your Dyson Filter Instead of Washing It

Washing can’t fix everything. You should replace your Dyson filter if you notice any of the following:

Visible Damage: Tears in the pleated material, holes in foam, or a cracked plastic housing.
Persistent Odor: If a musty or unpleasant smell remains after a thorough wash and complete dry, the filter media may be contaminated.
Reduced Performance: After washing, drying, and checking for blockages, suction is still significantly weaker than before.
Age: Dyson suggests replacing filters every 12-24 months with regular washing, depending on use.

Using a genuine Dyson replacement filter is always recommended for the best fit and performance.

FAQs About Washing Dyson Vacuum Filters

Can I use warm water to wash my Dyson filter?

It’s best to stick with cool or lukewarm water. Hot water can damage the filter’s delicate materials and potentially melt adhesives, leading to failure. Cool water is effective and safe.

How long does it really take for a Dyson filter to dry?

While the minimum is 24 hours, a full and guaranteed dry almost always requires 48 hours. In humid environments, it may take even longer. When in doubt, let it dry for an extra day.

My filter smells bad after washing. What did I do wrong?

A bad smell usually indicates it was put back in the vacuum while still damp, allowing mold or mildew to grow inside the pleats. It can also happen if it wasn’t rinsed thoroughly enough. Try washing it again, ensuring you rinse until the water is perfectly clear, and then dry for a full 48+ hours. If the smell persists, the filter likely needs to be replaced.

Can I wash the pre-motor filter and the post-motor filter the same way?

Generally, yes—both are washed with cool water only and air-dried. However, always refer to your specific model’s manual. Some pre-motor filters, especially foam ones, are more delicate and require gentler handling.

Is it okay to wash my Dyson filter in the washing machine or dishwasher?

Absolutely not. The agitation, heat, and detergents used in these appliances will destroy your filter. Hand washing with cool water is the only recommended method.

Why does my Dyson pulse or shut off after I washed the filter?

This is a classic sign of a damp filter. The vacuum’s safety sensor detects restricted airflow and shuts down to protect the motor. Remove the filter and allow it to dry completely for another 24 hours. This is the most common issue people face after washing.

Maintaining Your Vacuum Beyond the Filter

For peak performance, filter washing should be part of a broader maintenance routine. Here’s a quick checklist:

Empty the Bin Regularly: Don’t let it fill past the MAX line. Empty it after every use for best suction.
Clear Brush Bar Tangles: Regularly cut away hair and threads wrapped around the brush bar on floor tools.
Check for Blockages: Periodically inspect the hose, wand, and air pathways.
Wipe Down Seals: Clean the rubber seals on the bin and cyclone unit with a dry cloth to ensure a good seal.

Following these simple steps, especially regular filter washing, will keep your Dyson working powerfully for years to come. It’s a small task that makes a huge diffrence in your cleaning results and the longevity of your machine.
