What does this mean?Pros & Cons
Pros
Identical intake filter enclosures in my grow-house. Each cabinet has a 4 filter installed, 1 of which is vanleno. Both fans are identical and are delivering their rated output @ 195 cfm. Custom mesh with 53% open area allows for increased air flow.
Highlights
Quality
Exactly as described good quality for a good price

With that and only that criteria in mind i ran a series of anemometer tests on this 4 vanleno filter and its vivosun counterpart
