Anden 5813 MERV 11 Replacement Filter for Anden A320V1, A320V3 - 20 x 22 x 2

Anden A320 Filter Size, Settled: 20 x 22 x 2

If you came here for the size, here it is: 20 x 22 x 2 inches. Anden publishes that figure themselves, so there is no nominal-versus-actual gap to work around. You cannot say that about every filter in this category. The part number is 5813 and it covers both builds of the machine, the A320V1 and the A320V3. The unit takes a single panel. When you swap it, note which way the old one sat before you pull it out. Anden's instruction is to install the new one in the same direction.

What MERV 11 Holds Back on an Anden A320V1 or A320V3

MERV 11 sits in the middle of the pleated range. For a room full of plants that is about the right place to be. The EPA holds the grade to 65 percent or better capture from 1 to 3 microns, and 85 percent from 3 to 10. That is the leaf dust, the trimmed material and the fine grit that comes off growing media. What the panel is really protecting is the coil behind it. A clean coil keeps the machine pulling its rated pints. A loaded face makes it work harder for less water. Anden calls the construction multi-pleat with high holding capacity. That is their way of saying more media is folded into the frame than a flat panel carries. On timing, Anden speaks the grower's language rather than the HVAC one: replace the filter every 12 weeks, or at the end of a harvest.

Key Features

• Anden part 5813: The number to match for a single panel, which is how these are stocked
• 20 x 22 x 2, straight from Anden: Anden publishes this size themselves, so there is no rounding gap between the catalogue 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
• High holding capacity: Anden's own term for the multi-pleat build: more media in the same frame, so more dust before airflow drops off
• Covers both A320 builds: The A320V1 and the A320V3 take the same panel, so the V number does not change what you need
• One filter per unit: Anden's A320 manual lists a single filter, part 5813, behind one access door
• Keeps the coil clean: A loaded face makes the machine 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, written for grow rooms rather than for houses
