Shark Vacuum Filter

Shark Vacuum Filter Replacements: What to Know

Replacing worn or clogged filters keeps your Shark vacuum’s airflow strong and reduces fine particles recirculating into your home. Most models use a washable foam pre‑motor filter plus a felt and/or HEPA post‑motor exhaust filter. Always confirm what your specific model requires.

How to Choose the Right Filter

Filter type	Location	Washable?	Typical replacement	Use if	Avoid if
Foam (pre‑motor)	Before the motor, under the dust cup	Yes (rinse only)	Replace every 6–12 months or when misshapen	You want low‑cost, regular maintenance	You plan to use soap/hot water (can damage foam)
Felt (pre‑motor)	Often paired with foam	Varies by model; usually not washable	Replace every 3–6 months or when heavily soiled	Need extra fine dust capture before the motor	If your manual forbids washing; replace instead
HEPA/post‑motor (exhaust)	After the motor, behind a grill	Usually not washable	Replace every 6–12 months (sooner with pets/smokers)	Allergy sensitivity or finer particle capture	If your manual specifies a different type/interval

Tip: HEPA filters capture very fine particles. If your vacuum supports HEPA, use genuine or equivalent‑spec parts and follow the manual’s guidance.

Compatibility: Match Parts to Your Model

1. Find the model number on the rating label (often under the dust cup, on the back/bottom, or near the power cord). Common prefixes include NV, ZU, LA, UV, and IZ.
2. Locate the filter kit or part code in your manual or on the manufacturer’s site.
3. Verify whether your unit uses a sealed system HEPA filter and whether the felt filter is washable or replace‑only.

If you can’t find an exact part code, compare the filter’s shape and measurements, or contact support with your full model number (e.g., ZU62, NV352, LA502).

Care and Maintenance

Rinsing foam pre‑motor filters (2–5 minutes active time)

1. Turn off and unplug the vacuum; remove the dust cup.
2. Remove the foam filter. Tap gently to release loose dust.
3. Rinse with cool water until clear. Do not use soap or wring hard.
4. Air‑dry completely for at least 24 hours.
5. Reinstall only when fully dry to prevent mold or motor damage.

General schedule

• Light use (weekly): Rinse foam every 2–3 months; replace HEPA yearly.
• Pets/allergies or heavy use: Rinse foam monthly; replace HEPA every 6–9 months.
• Replace felt when stained, matted, or if airflow doesn’t improve after cleaning.

When to Replace vs. Clean

• Replace if the filter is torn, misshapen, has lingering odors, or sheds material.
• If suction is still low after rinsing and drying the foam, upgrade to a full kit (foam + felt + HEPA) and check hoses for blockages.

Pack Sizes: What to Buy

• Single replacements: Infrequent use or one‑time restore of suction.
• 2‑packs: Keep a clean spare ready while the other dries.
• Complete kits (foam/felt + HEPA): Best yearly refresh or when moving to a new home.
• Bulk cases: Ideal for property managers, rentals, or cleaning businesses.

Safety Notes

• Always unplug before servicing.
• Reinstall only when filters are fully dry.
• Do not use hot water, detergents, or a dryer unless your manual explicitly allows it.
• Do not wash HEPA/post‑motor filters unless the manual says they are washable.

Troubleshooting Signs of a Clogged Filter

• Reduced suction or the vacuum running hotter than usual.
• Visible dust puffing from the exhaust.
• Musty odors that return quickly after cleaning.

FAQ

How often should I replace Shark filters?

Foam: replace every 6–12 months. Felt: every 3–6 months (or as your manual advises). HEPA: every 6–12 months. Increase frequency with pets, renovations, or heavy use.

Can I wash all Shark filters?

Foam is generally washable with cool water only. Felt and HEPA are often not washable—tap to clean or replace. Always follow your model’s manual.

Why did suction drop after washing?

Filters may still be damp, restricting airflow. Let them dry at least 24 hours. Also check for hose clogs, a full dust cup, or a worn belt (for brushroll models).

Do third‑party filters void warranties?

Using non‑OEM parts typically does not void a warranty by itself, but damage caused by incompatible parts may not be covered. Keep receipts and verify compatibility.

How do I find the right part number?

Use the model number from your vacuum’s rating label and cross‑reference the filter kit in your manual or the manufacturer’s website. Match shape and dimensions if needed.
