Anden 5781 MERV 11 Replacement Filter for Anden A210V1 - 14 x 18 x 2

The Anden A210V1 Filter Size, and Why It Is a Short List

Anden publishes this panel at 14 x 18 x 2 inches under part number 5781. They name one machine against it: the A210V1. That is the whole compatibility list. It is worth saying plainly, because most of the work in finding a filter is working out which of several similar panels fits your machine. Here there is nothing to work out. The A210V1 takes one filter, that filter is 5781, and the size is the size Anden prints.

MERV 11 in a Grow Room, and What the Panel Is Protecting

The grade matters more than it sounds. The EPA holds MERV 11 to 65 percent or better capture between 1 and 3 microns, and 85 percent from 3 to 10. In a flowering room that band is where the trouble lives. Leaf dust, trimmed material, the grit that lifts off media whenever somebody moves a pot. Anden builds the filter as a multi-pleat with what they call high holding capacity. The media is folded rather than flat, so there is more surface inside the frame. More surface means more room for dust before airflow starts to drop. Behind it sits the evaporator coil, and that is the part worth caring about. Coils are cleaned with a teardown. Filters are changed in a minute. Anden's guidance is to replace the panel every 12 weeks or at the end of a harvest.

Key Features

• Anden part 5781: The number to match for a single panel, which is how these are stocked
• 14 x 18 x 2 as Anden publishes it: Their own figure for this part, so there is no gap between the listing and a tape measure
• MERV 11 multi-pleat media: EPA holds the grade to 65 percent or better from 1 to 3 microns and 85 percent from 3 to 10
• One machine, one filter: The A210V1 is the only unit Anden names against this part, so there is no compatibility puzzle to solve
• High holding capacity: Folded media rather than flat, which is what lets it hold a cycle of room dust before airflow suffers
• Keeps the coil clean: A loaded face makes the unit draw full power for fewer pints, so fresh media is the simplest way to hold output
• Every 12 weeks or every harvest: Anden's published interval, tied to the grow cycle rather than to a calendar quarter
