UK Manufacturer of Pond Filter Brushes

For over 40 years, The Speedy Brush Company has been manufacturing pond filter brushes from our purpose-built factory in Kent. We pioneered twisted-wire brush technology for pond filtration systems in the early 1980s and have since manufactured millions of filter brushes for domestic, commercial and industrial installations across the UK and worldwide.

As the manufacturer behind the Black Knight range (the world's best-selling pond filter brush) we combine decades of specialist knowledge with UK-based production to deliver filter brushes that are trusted by pond keepers, koi farms, public aquariums, commercial hatcheries and water treatment facilities around the globe.

Whether you're a trade buyer, a commercial operator requiring large volumes, or you need a bespoke specification that standard ranges don't cover, you're in the right place.

The Black Knight Range: Designed & Made by Speedy Brush

The Black Knight pond filter brush range is designed, manufactured and shipped exclusively from our factory in Maidstone, Kent. Every brush is constructed from high-quality Hydrotek polypropylene filament twisted onto two stainless steel wires: a method that produces a dense, durable cylindrical brush capable of outstanding mechanical and biological filtration performance.

The Black Knight range has become the most widely used and extensively tested pond filter medium in the world, trusted across:

• Domestic garden ponds and koi ponds
• Public aquariums and ornamental water features
• Commercial fish farms and hatcheries
• Research institutes and scientific facilities
• Sewage treatment and water processing plants

Looking to buy Black Knight pond filter brushes? The full consumer range  (including all available sizes, bulk packs and spawning brushes) is available on the dedicated Black Knight website.

Bespoke and Custom Water Filtration Brushes

As a manufacturer rather than a retailer, Speedy Brush is uniquely placed to produce filtration brushes to your exact specification. If the standard Black Knight range doesn't meet your requirements (whether due to size, volume, filament material or application) we can manufacture to order.

Custom Sizes and Specifications

Our manufacturing capability extends well beyond the standard consumer range. We can produce pond and water filtration brushes in non-standard diameters and lengths, with filament type, density and core wire specification tailored to your application. If you have a technical drawing, an existing sample, or simply a set of dimensions, contact our team and we'll advise on the best approach.

Trade and Wholesale Orders

We supply trade customers and wholesale buyers directly from the factory. If you're a pond specialist retailer, aquatic centre, landscape contractor or distributor looking to stock Black Knight brushes or commission a private-label product, we'd be glad to discuss pricing, minimum order quantities and lead times.

Call our team on 01622 747299 (Monday to Friday, 9am–5pm) to discuss your requirements.

Commercial and Industrial Filtration

For large-scale or industrial filtration applications (including fish farms, hatcheries, public aquariums and water treatment facilities) we have extensive experience supplying high-volume brush orders built to precise specifications. Our brushes are already in use at installations across the UK and internationally, and our technical team can advise on filter chamber design, brush configuration and spacing to maximise filtration efficiency.

Air Filtration Brushes

In addition to our water filtration range, Speedy Brush also manufactures horsehair brushes for air filtration systems. These are produced to order based on your specific requirements. Please call us on 01622 747299 to discuss your application and we'll be happy to provide a quotation.
