FAQs
What is the difference between KWT and Competitor Particle Separators?
What are the particle separator's dimensions?
How Does the KWT Particle Separator Work?
The KWT Particle Separator uses the induction of the engine to pull the dusty air through the front and bottom of the filter. The internal cyclonic tubes separator the clean air from the dust. The dust is captured in the bottom dirt collection tray and the clean air is delivered to your stock filter box and engine.
What is the CFM Threshold?
1000CC engines up to 300 CFM
What ways can I mount the KWT Particle Separator?
The KWT Particle Separator can be mounted forward, backward, and sideways. The KWT Filter uses the induction of the engine to pull the airflow through the front and bottom of the air filter to ensure air flow efficiency. There are several mounting solutions available utilizing the KWT the dual-arm bracket and the single-point universal mounting bracket. There are some photos of the various mounting solutions.
Has the KWT Particle Separator been Dyno tested?
Yes, see the "How it Works" page for ISO 5011 and Dyno testing results.

What happens if I am riding in wet or rainy conditions?
The KWT Filter has been tested and designed for rain and water intrusion. The inlets inside the filter are located on the top side of the intake making it hard for water to reach. The screen pulls down most of the water to the lower section of the intake where weep holes are located, visible if you turn the KWT Filter upside down. A slight amount of water may enter the system and into the dirt collection chamber but is easily removed by emptying the detachable dirt tray.
The filter has been tested in rainy conditions with little water intrusion into the dirt collection chamber. If you typically ride in rain, having a prefilter may not be your best option since particle separators are designed to filter dust particles which are not present in these conditions.
How do I clean my KWT Particle Separator?
Can my KWT Particle Separator be installed behind my windshield?
Yes, it can be installed on a vehicle with a rear windshield. Since the KWT Particle Separator uses the induction of the engine to pull the airflow through rather than the need for forced air, it can be mounted behind a rear window and still work as efficiently as designed to. Here is a photo of Talon install with a rear windshield.
What percentage of dust does it remove?
Up to 98% of dust and dirt are removed before reaching you stock air filter.
What is the difference between Version 1 and Version 2 (X2)?
Some of the upgraded features of X2 include an updated innovative cyclonic technology, dual air intake which increases air flow, higher efficiency at removing dirt and dust particles, and a larger detachable dirt collection chamber.
Where can I find the install instructions?
Each installation instruction is located under each product on our website.
Also, you can find installation videos for each vehicle on our YouTube Channel.
Is there any power needed for the filter to run?
No power is required for our pre-filter to work. The “how it works” brochure explains our technology and how it uses the induction from the engine to pull the air through the particle separator. Hence, no power, no fan and no noise. Dyno tests on the Can Am Turbo indicate no change in HP or restriction of airflow to the engine. The fuel efficiency with and without our particle separator has been measured on a RZR 1000 XP with no difference.
A competitor claimed that they tested KWT’s particle separator and says it does not work. Have you done IS0 5011 testing on your particle separator?
In November 2018, a competitor claimed they ran a performance test on the KWT Particle Separator per ISO 5011 Filter Test Standards. They provided results on the filter efficiency of the KWT Particle Separator at 14.48%. KWT Filters own ISO 5011 test series shows the efficiency to be much higher than this in the 90% range. KWT investigated the competitor's claim and found their test to be invalid. The competitor modified the test to suit their marketing needs by making up their own “Test Terminal Condition” which effectively allows the KWT Filter to fill its dirt collection chamber and stop working. What they’ve done is selected test stopping point (Test Terminal Condition) that would represent never opening the KWT Filters Sight Glass and extracting the dirt over years of service. It clearly states in the ISO 5011 Standard, Section 3.1.19 Test Terminal Condition, “an agreed value” and a condition of terminating the filter test is “the dust-removing efficiency falls to a specified or agreed value”. KWT Filters did not agree to the competitor's Test Terminal Condition nor does the competitor test agree with the requirements of terminating the ISO 5011 testing. Since the KWT Filter is Cyclonic and will never increase air restriction like a paper filter when dust accumulates, the ISO Test requires Cyclonic Filters to have a test termination such that when “the cleaner has been fed with sufficient quantity of dust for its efficiency to be determined as accurately as required” (Section 7.5.2.10 of ISO 5011), which is how KWT tests its filter efficiency. What our competitor has done is solely a marketing ploy to undermine our product. KWT filters mission and focus is to bring enhanced filter less technology to the off-road industry.
