Vacuum Accessories & Supplies Price Comparison 2026
Compare 735 vacuum accessories & supplies — filters, dust bags, hoses and brush heads — from Kärcher, Hoover, Bosch and more, at prices from 3 £.
Replacement filters, dust bags, hoses, brush heads — the accessories market for vacuums is far larger and more nuanced than most people expect. With 735 products listed across brands ranging from budget-friendly Nedis to professional-grade Festool, the price spread is striking: you can spend as little as 3 £ on a basic dust bag or push past 27 £ for a multi-stage filtration kit designed for workshop use. Knowing what you actually need before you buy is half the battle.
Kärcher dominates the catalogue here with nearly 150 products, and their accessories are generally well-priced relative to performance — though we'd note that Festool commands a significant premium (average around 24 £ across the full range, but Festool sits well above that). For everyday home use, Hoover and Numatic offer solid consumables at sensible prices, and Numatic's dust bags in particular are a reliable choice for Henry and HettyHoover owners. Bosch accessories tend to sit in the mid-range and integrate cleanly with their own vacuum lineup.
One pattern we see repeatedly: buyers purchase the wrong filter. Compatibility is everything in this category. A HEPA H13 filter that doesn't seat correctly creates air leaks, bypasses filtration entirely, and can strain the motor over time. Always cross-reference your vacuum's model number before ordering — several brands now offer QR-code matching or model-lookup tools to reduce this exact error. If you're an allergy sufferer, don't compromise on HEPA certification; a sealed disposal system paired with a genuine HEPA filter makes a measurable difference to indoor air quality.
For workshop and trade use, Makita and Draper Tools accessories offer strong value — Draper in particular has a broad range of filters, anti-foaming agents, and drum vacuum consumables that are well represented among the most-compared products on this page. Wet-dry vacuum owners should also factor in anti-foaming agents; skipping them risks motor damage that far outweighs the cost of the additive itself.
Whether you're restocking consumables for a cylinder or upright vacuum, kitting out a handheld vacuum, or sourcing professional-grade filters for a stick vacuum, comparing prices across retailers — from Amazon.co.uk and Currys to specialist tool suppliers — can yield meaningful savings, particularly on frequently replaced items like dust bags and pre-filters.
How to Choose the Right Vacuum Accessories
Most people only think about vacuum accessories when something stops working — suction drops, a bag splits, or a brush head wears out. But buying the wrong replacement is one of the most common (and costly) mistakes in this category. Here's what actually matters when you're comparing options.
Model compatibility before anything else
This is non-negotiable. A filter or dust bag that doesn't match your vacuum's exact model number will either not fit at all or — worse — fit loosely and create air leaks that bypass filtration entirely. Check your vacuum's model number (usually on a label underneath the machine) and cross-reference it with the accessory's compatibility list. Many brands including Kärcher and Bosch publish model-matching tools online. Universal adapters exist, but they're a compromise: fine for brush heads and crevice tools, but not recommended for filters where a proper seal is critical.
HEPA rating — and whether you actually need it
HEPA H13 captures 99.97% of particles at 0.3 microns — that includes dust mite allergens, pollen, and fine bacteria. If anyone in your household has asthma or allergies, a genuine HEPA filter (not just 'HEPA-style') paired with a sealed disposal system is worth the extra spend. For general cleaning without allergy concerns, a good pleated cartridge filter is perfectly adequate and often cheaper to replace. Be wary of vague marketing claims — look for the H13 or H14 designation explicitly stated on the packaging.
Disposable vs. reusable: the long-term cost calculation
Disposable dust bags and filters are convenient but add up quickly — replacing a dust bag every 4–6 weeks at 10 £ per pack costs considerably more over a year than a washable filter at 17 £ that lasts 12–18 months. Reusable filters make most sense for frequent users and workshop vacuums. That said, for allergy management, sealed disposable bags are often preferable because they contain allergens during disposal — a washable filter shaken out over a bin defeats the purpose.
Hose diameter and connection type
The two standard diameters in the UK market are 32mm (common in domestic vacuums) and 38mm (typical for workshop and wet-dry models). A 50mm connection appears on larger industrial machines. Getting this wrong means either a loose fit with suction loss or an accessory that simply won't connect. Bayonet fittings (twist-and-lock) are common on European models including Kärcher; push-fit connectors are more typical on Hoover and Numatic. Multi-adapter kits can bridge the gap but add bulk to the connection.
Anti-foaming agents for wet-dry vacuums
Often overlooked, anti-foaming agents are essential if you're using a wet-dry vacuum to pick up soapy water or foam-producing liquids. Without them, foam can overflow into the motor housing — damage that voids most warranties and is expensive to repair. Draper Tools' anti-foam concentrate (designed for their WDV21 and WDV30SS models) is a good example of a brand-specific product worth buying correctly. Dosage matters: too little is ineffective, too much wastes product. Follow the 1:10 dilution guidance on concentrate bottles.
Brush head bristle stiffness by surface type
Stiff bristles are effective on carpets and workshop floors but will scratch hardwood, laminate, and delicate tiles. Soft natural-hair brush heads suit smooth floors and upholstery. Combination heads with adjustable bristle exposure offer the most versatility but tend to cost more. For a single-surface household, a dedicated brush head outperforms a universal compromise. Check whether the bristle stiffness is specified — many budget accessories omit this detail entirely, which is itself a warning sign.
- Everyday consumables (From 3 £ to 10 £) : Basic dust bags, foam pre-filters, and simple crevice tools. Brands like Nedis and Draper Tools are well represented here. Fine for standard cleaning without allergy concerns, but don't expect HEPA certification or long service life. Good for stocking up on frequently replaced items.
- The practical sweet spot (From 10 £ to 17 £) : Where most genuine HEPA filters, quality dust bags (including Numatic's sealed bags), and decent brush heads sit. Hoover, Kärcher, and Numatic accessories in this range offer reliable compatibility and reasonable longevity. This is where we'd direct most home users.
- Mid-range and specialist (From 17 £ to 27 £) : Pleated cartridge filters, multi-stage filtration kits, and branded hose assemblies from Bosch, Makita, and Kärcher. Worthwhile for workshop use or households with allergy sufferers who need proper HEPA sealing. Makita and Bosch accessories in this bracket are built to last.
- Professional and Festool territory (Over 27 £) : Festool dominates this segment — their accessories are engineered for trade use and carry a significant price premium. Genuinely worth it for professional contractors who need certified dust extraction (particularly for fine dust from sanding). For home use, this spend is rarely justified unless you own a Festool vacuum already.
Top products
- Numatic 907075 vacuum accessory/supply Dust bag Cylinder vacuum (Numatic) : The go-to dust bag for Henry and Hetty owners — reliable sealed disposal, widely available across UK retailers, and consistently well-priced. Not the cheapest option, but the fit and allergen containment justify the cost over generic alternatives.
- Draper Tools 20955 vacuum accessory/supply Filter Handheld vacuum (Draper Tools) : A solid cloth dust filter for the WDV30SS handheld — good value for workshop users who need frequent replacements. Works as intended but is model-specific, so don't buy it unless you own the matching Draper vacuum.
- Draper Tools 48558 vacuum accessory/supply Filter (Draper Tools) : One of the better-value HEPA filters in the catalogue — covers both the WDV21 and WDV30SS models, which is a useful dual compatibility. If you're doing dusty workshop tasks and want genuine HEPA protection without Festool prices, this is the sensible pick.
- Kärcher 2.641-959.0 vacuum accessory/supply (Kärcher) : Kärcher accessories are reliably well-engineered and this is no exception — good build quality and broad compatibility within the Kärcher range. Priced fairly for what it is, though you'll want to confirm model fit before ordering as Kärcher's product codes can be confusing.
- Bosch 2 607 432 037 vacuum accessory/supply (Bosch) : Sits at the upper end of the mid-range, which is typical for Bosch accessories. Build quality is dependable and it integrates cleanly with Bosch's vacuum lineup. Worth comparing prices across retailers — this one in particular shows meaningful variation between merchants.

Frequently Asked Questions
How do I know which filter is compatible with my vacuum?
Check the model number printed on your vacuum's label (usually underneath the machine or inside the dust compartment), then match it against the accessory's compatibility list. Most major brands — Kärcher, Bosch, Hoover — publish model-lookup tools on their websites. Buying a filter listed as 'universal' is a risk for filtration accessories specifically: a loose fit creates air leaks that bypass the filter entirely, reducing both suction and air quality.
Is a HEPA filter worth the extra cost for a home vacuum?
Yes, if anyone in your household has asthma, hay fever, or dust mite allergies — a genuine HEPA H13 filter captures 99.97% of particles at 0.3 microns, including allergens that standard filters miss. For households without allergy concerns, a quality pleated cartridge filter is adequate and cheaper to replace. The key word is 'genuine': look for H13 or H14 explicitly stated, not just 'HEPA-style' or 'HEPA-type', which are marketing terms without certification.
How often should I replace vacuum dust bags and filters?
Dust bags should be replaced when around two-thirds full — overfilling restricts airflow, strains the motor, and reduces suction noticeably. For average home use that typically means every 4–8 weeks. Disposable filters generally last 3–6 months; washable filters can last 1–2 years with regular rinsing. A useful rule of thumb: if suction has dropped and the bag isn't full, the filter is the first thing to check.
Can I use third-party accessories instead of branded ones?
For brush heads, crevice tools, and hose extensions, third-party accessories are generally fine — compatibility is easier to verify and the performance difference is minimal. For filters and dust bags, we'd be more cautious: generic alternatives often lack proper HEPA certification, may not seal correctly, and can void your vacuum's warranty. The price saving on a filter is rarely worth the risk of reduced air quality or motor damage over time.
What's the risk of skipping anti-foaming agent in a wet-dry vacuum?
Skipping anti-foaming agent when vacuuming soapy water or foam-producing liquids is a genuine motor risk. Foam can overflow into the motor housing, causing damage that most manufacturers won't cover under warranty. Anti-foaming agents are inexpensive — typically well under 10 £ — and the cost of ignoring them can be a full vacuum replacement. Use the correct concentration (usually 1:10 for concentrate products) and don't substitute washing-up liquid or other household products.
Are Festool vacuum accessories really worth the premium price?
For professional contractors, yes — Festool's dust extraction accessories meet strict certified dust class ratings (L, M, H) required for trade use, particularly when sanding or cutting materials that produce fine or hazardous dust. For home users, the premium is hard to justify unless you already own a Festool vacuum. At prices well over 27 £, you're paying for trade-grade certification and build quality that most domestic cleaning tasks simply don't require.
What hose diameter do I need — 32mm or 38mm?
32mm is the standard for most domestic vacuums sold in the UK, including the majority of Hoover, Miele, and Dyson-compatible accessories. 38mm is typical for workshop and wet-dry vacuums, including most Kärcher and Numatic industrial models. Check your existing hose's internal diameter before ordering — a 6mm difference sounds small but means the connection either won't fit or will be loose enough to lose meaningful suction. Some multi-adapter kits bridge both sizes, but they add length and a potential leak point at the joint.
