KNOKOO FES035 Panel-Mounted Fume Extractor Filter Cost-Effective to Replace Individually

KNOKOO FES035-set Dual-Effect Panel Filter Set: Ensuring the FES035 Fume Extractor Maintains "Powerful Purification"

Still troubled by the FES035 welding fume extractor's inability to effectively remove fumes? Replacing the entire filter set is too wasteful, and you only want to replace the dirty layer but don't have the right replacement parts? The KNOKOO FES035 dedicated fume extractor filter set features a dual-layer design of "pre-filter + main filter," intercepting 99.97% of 0.3μm dust, tar, and PM60 particles. Its precise 16.6×16.6×3.1cm dimensions perfectly fit the FES035 body, and it supports individual replacement of each filter layer—no need to discard the entire set. This extends the fume extractor's lifespan and reduces consumable costs, ensuring consistently clean air in 3D printing, laser engraving, and electronic soldering environments.

I. Core Advantages

1. Dual-layer Precision Filtration + 99.97% Purification Rate, "Complete Interception" of Harmful Pollutants

First Layer Pre-filter (16.6×16.6×3.1cm): Specifically intercepts large PM60 particles (such as 3D printing residue, laser engraving debris, and soldering slag). Replace every 10-60 days to prevent large particles from clogging the main filter and reduce its workload.

Second Layer Main Filter (16.6×16.6×3.1cm): Deeply filters fine particles ≥0.3μm and tar (such as electronic soldering fumes, laser marking fumes, and 3D printing VOCs adhering to the filter). Replace every 2-7 months. Filtration efficiency reaches 99.97%, ensuring that the exhaust air is free of harmful substances.

Benefits: The dual-layer filter works synergistically, covering all dimensions of pollution from "large particles → fine particles → sticky substances," making the FES035 fume extractor ideal for industrial welding, DIY projects, and other applications. 1. Maintains optimal purification during creative and other scenarios, preventing smoke leakage due to filter failure.

2. Individual Replacement Design + Precise Size, Cost-Effective and More Fitting

Two-layer filter replacement: No need to replace the entire set due to wear and tear on a single layer. For example, replace only the pre-filter when it gets dirty. Compared to replacing the entire set, long-term use can save 40% on consumable costs (based on monthly pre-filter replacement, the annual cost of replacing the pre-filter individually is 500+ RMB lower than replacing the entire set).

16.6×16.6×3.1cm Precise Size: Perfectly matches the filter compartment of the FES035 fume extractor. No cutting or adjustment is required; simply open the filter compartment and insert it directly, avoiding filter gaps and airflow leakage caused by size mismatch.

Details: The filter edges feature a sealed sponge design, ensuring a tight fit with the compartment wall after installation, preventing unfiltered air from escaping through gaps and ensuring undiminished purification efficiency.

3. Tool-free installation + CE certification: Safe and convenient.

Tool-free installation/removal: No need for screwdrivers or wrenches. Simply open the filter compartment of the FES035 fume extractor, remove the old filter, and insert the new one. Replacement is completed in 1 minute, even for beginners. It won't delay your work (e.g., if the filter gets clogged halfway through 3D printing, you can quickly replace it and continue printing).

CE certification + environmentally friendly materials: The entire filter set has passed EU CE safety certification. The materials are odorless and do not cause secondary pollution. Even when used in a closed electronics repair shop, they will not release harmful substances. The main filter uses high-density filter material with a large filtration area and low airflow resistance, which does not affect the FES035's suction power.

II. Frequently Asked Questions (Answers in Advance)

Q1: Can this FES035-set filter cartridge only be used with the KNOKOO FES035 fume extractor? Can it be used with the same model from other brands?

Yes, this filter cartridge is specifically designed for the KNOKOO FES035 model—its dimensions of 16.6×16.6×3.1cm and the position of the sealing sponge are perfectly matched to the FES035's filter cartridge compartment. If other brands of fume extractors have the same compartment size and installation structure as the FES035, it is theoretically possible to try it. However, to ensure filtration efficiency (avoiding air leakage through gaps) and equipment compatibility, it is recommended to use it primarily with the FES035. If you need to adapt it to other models, please contact customer service and provide your equipment parameters; we will recommend the corresponding fume extractor filter.

Q2: How do I determine when the pre-filter and main filter cartridge need replacing? Is there a simple method?

There are three intuitive ways to judge:

1. Check the appearance: If the pre-filter cotton surface is noticeably blackened and covered with large particles (such as 3D printing filament residue), and cannot be cleaned even with gentle tapping, it needs to be replaced.

2. Test the suction power: After turning on the FES035, place your hand near the suction port. If the suction power feels significantly weaker, or if the smoke swirls around in the nozzle and cannot be drawn in, it indicates that the main filter may be clogged.

3. Check the time: Based on a usage frequency of 4-6 hours per day, the pre-filter lasts 10-60 days, and the main filter lasts 2-7 months. Even if there is no obvious change in appearance, it is recommended to replace it after the cycle to avoid a decrease in purification efficiency.

Q3: Can the pre-filter cotton be cleaned and reused after vacuuming? Will it affect the filtration effect?

Reuse is not recommended! The pre-filter's function is to "intercept large particles and protect the main filter." When cleaning with a vacuum cleaner, some small particles may become embedded in the filter fibers. Upon reuse: firstly, these residual particles will be carried into the main filter by airflow, shortening its lifespan; secondly, the filter pores may deform due to cleaning, reducing its ability to intercept large particles later. From a cost perspective, the pre-filter has a shorter replacement cycle and lower unit price, making a one-time replacement more economical and better protecting the main filter.

Q4: Is there an installation tutorial after purchase? I'm worried that installing it incorrectly will affect the use of the FES035 fume extractor.

Yes! Each set comes with an illustrated installation manual, which clearly indicates the installation sequence as "pre-filter → main filter" (pre-filter near the air inlet, main filter near the interior of the unit). It also includes a disassembly diagram of the FES035 filter compartment, making it easy for beginners to understand. We also offer online support; if you are unsure about the correct orientation during installation, you can take a photo of the filter compartment and send it to customer service for real-time guidance to ensure you don't install it backwards—incorrect installation not only affects filtration efficiency but may also cause premature clogging of the main filter.

Q5: Will the filter cartridges be damaged during transportation? If I find the filter media damaged upon receipt, can I return or exchange it?

We use a 20×20×15cm thickened cardboard box for packaging. Each filter cartridge is individually wrapped with a moisture-proof film, and the interior is filled with cushioning foam to prevent deformation during transportation. If you find the filter media damaged, the size incorrect, or the sealing foam detached upon receipt, as long as it is unopened and unused, you can return or exchange it within 7 days without giving a reason.
