prima klima  vs bullfilter

Which 200mm filter for 1300m³/h?

For large growth chambers, choosing the right carbon filter for a 1300 m³/h extractor is crucial. Today, we compare two essential references: the Prima Klima K2605 Ø200 mm and the BullFilter 200x600. These models are designed for the same extraction power, but differ significantly in terms of format, materials and longevity. Here's our full analysis to help you choose the best filter for your needs.

Technical specifications

Here's a summary of the technical specifications for both filters:

FeaturesPrima Klima K2605BullFilter 200x600
Maximum air flow 1300 m³/h 1300 m³/h
Optimum airflow ~1000 m³/h ~1300 m³/h
Flange diameter Ø 200 mm Ø 200 mm
Dimensions (ø × L) 280 × 800 mm 200 × 600 mm
Total weight 13.2 kg 8.66 kg
Activated carbon 9.2 kg (coconut) 7.2 kg (Australian RC-4/8)
Materials Steel + fiber pre-filter Aluminum + fiber pre-filter
Life expectancy ≈ 12 months ≈ 18 months
Pre-filter included Yes Yes (x2)

In direct comparison, the Prima Klima K2605 offers a robust structure, a thick carbon bed and a large diameter for smoother airflow. It's perfect for installations seeking a flow rate slightly below maximum to extend filter life.

In contrast, the BullFilter 200x600 offers very solid performance, with a lighter, more compact structure, while incorporating 7.2 kg of highly absorbent Australian charcoal. It also boasts a longer service life and two pre-filters.

Service life and maintenance

Visit Prima Klima K2605 has a rated service life of around 12 months in continuous use. After this period, replacement is recommended to maintain effective filtration. In contrast, the BullFilter 200x600 boasts a longer service life: up to 18 months of efficiency, according to the manufacturer. This difference can be explained by the quality of the Australian RC-4/8 activated carbon, recognized for its long-lasting adsorption capacity, as well as by a well-utilized volume despite a more compact filter.

Both models feature a fiber pre-filter to protect the activated carbon from dust particles. To preserve filtration capacity and ensure optimum airflow, we recommend regular cleaning of the pre-filter (vacuum or dry). The BullFilter comes with 2 pre-filters, a significant advantage that allows rotation during cleaning, further extending the filter's durability.

Please note: the Prima Klima K2605 is designed with a removable metal body, which theoretically offers the possibility of replacing worn activated carbon. This option, although a little technical, represents a real plus for advanced users concerned with durability. The lighter, non-refillable BullFilter, on the other hand, focuses on simplicity and ready-to-use efficiency.

Ease of installation

Both BullFilter and BullFilter can be installed directly at the intake of your air extractor or inside your grow box. Thanks to their standard Ø200 mm flange, they are compatible with the majority of 200 mm extractors on the market, without the need for an adapter.

The BullFilter 200x600 is lighter (8.66 kg) and shorter, making it much easier to handle, especially at height. Its compact size reduces the load suspended in the grow tent, a real asset if you're working alone or in a confined space.

In comparison, the Prima Klima K2605 weighs over 13 kg for a length of 80 cm: it therefore requires sturdy supports (reinforced straps, metal hooks) for secure attachment. This weight can be a limiting factor in certain configurations, especially if you have a light structure or a low tent ceiling.

In short, both filters are easy to install, but the BullFilter gains a slight advantage here thanks to its superior maneuverability and reduced footprint, without compromising filtration performance.

Value for money and durability

The BullFilter 200x600 is a top-of-the-range solution optimized for 200 mm extractors. Its price is generally slightly lower than that of the Prima Klima K2605, while offering a longer service life (18 months vs. 12 months). Supplied with two pre-filters, it also offers a long-term economic advantage, with less maintenance required between cycles.

The Prima Klima K2605, for its part, justifies a slightly higher price by its robust metal construction and the quality of its coconut activated carbon. Its greater carbon capacity (9.2 kg) makes it a high-performance filter for particularly odorous growing environments or very intensive installations. It can also be considered on a long-term basis if you wish to manually refill it with carbon, although this operation remains reserved for experienced users.

In terms of customer feedback, both brands enjoy a solid reputation in the world of indoor cultivation. BullFilter is renowned for the lightness and efficiency of its filters, while Prima Klima seduces customers with its reliability and durable design.

Ultimately, when price is weighed against durability and practicality, BullFilter offers better overall value for money for standard use. The Prima Klima will be better suited to demanding users looking for ultra-efficient filtration with a large carbon reserve.

Verdict: If you're looking for a durable, lightweight filter that's immediately ready for a 1300 m³/h installation, the BullFilter 200x600 is an excellent choice.
