Maximum Filtration, Minimum Maintenance
The Netlea G2 Prefilter is a revolutionary external prefilter system that dramatically reduces main filter maintenance while delivering superior water purification through innovative design and massive filtration capacity.
Fish Manure Interception Bin – Reduce Cleaning Frequency
The unique fish feces interception chamber design intercepts and settles fish waste and large particles of impurities at the bottom of the filter barrel, preventing filter cotton from clogging in the upper section. This intelligent design reduces the frequency of filter cotton cleaning significantly – ordinary front barrels typically require weekly cleaning, while the No. 2 Prefilter semi-cotton version can go 4–8 weeks between cleanings.
Reduced Main Filter Cleaning – Save Trouble and Worry
The super-large filter material capacity provides more efficient water purification, keeping the main filter tank clean for 8–12 months. This greatly reduces the frequency of main filter cleaning, stabilizes the nitrification system, and saves you trouble and worry while maintaining pristine water quality.
22mm Large Outlet – Nearly 2× Water Flow
The innovative 22mm large water inlet and outlet quick connection delivers approximately 2 times the filtered water volume compared to the No. 1 prefilter (16mm), meeting the filtration needs of various planted tank specifications and high-bioload aquariums.
10.7× More Filtration Surface Area
The innovative gear-shaped filter cotton design provides twice the filtering effect under the same volume, dramatically improving pre-filtering performance:
-
No. 2 Prefilter: 171,449mm² effective filter surface area | 6.9L capacity | 10.7 items filtration efficiency
-
No. 1 Prefilter: 80,042mm² effective filter surface area | 3.8L capacity | 5 items filtration efficiency
-
Other Brand Prefilter: 16,000mm² effective filter surface area | 5L capacity | 1 item filtration efficiency
