Anden 5772 MERV 11 Replacement Filter for Anden A70 - 8 x 11.75 x 1

Anden A70 Filter Size: 8 x 11.75 x 1, and the Part Number to Match

The A70 is the smallest dehumidifier Anden builds for growing, and it takes the smallest filter in their range. Anden publishes it at 8 x 11.75 x 1 inches under part number 5772. One machine, one panel, with nothing else named against it. The middle figure is Anden's own and it is not a rounding. Some listings write it as 11-3/4, which is the same measurement expressed in fractions rather than a different part.

What a Small Face Means for a MERV 11 Panel

A small face carries less media, and less media fills sooner. That is a function of the machine's size rather than a shortcoming in the filter. It does mean the change interval carries more weight here than on a large overhead unit with room to spare. The media itself is the grade Anden uses across the line. The EPA holds MERV 11 to 65 percent or better capture from 1 to 3 microns, and 85 percent from 3 to 10. That covers leaf dust, trimmed material and the grit that lifts off growing media. Anden folds it into a multi-pleat, which puts more surface inside the frame than a flat panel would carry. Behind the panel sits the evaporator coil. Keeping that face clean is what holds a small machine at its rated pints, and a small machine has the least margin to give away. Anden's guidance is to replace the filter every 12 weeks or at the end of a harvest.

Key Features

• Anden part 5772: The number to match for a single panel, which is how these are stocked
• 8 x 11.75 x 1 as Anden publishes it: Written 11-3/4 on some listings, which is the same measurement in fractions
• The smallest panel in the range: No other Anden dehumidifier filter has a smaller face, which is worth knowing when you plan the interval
• 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
• Less media, less patience: A small face fills sooner than a large one, so the change interval carries more weight on this machine
• 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
• One machine only: The A70 is the only unit Anden names against part 5772
• Every 12 weeks or every harvest: Anden's published interval, tied to the grow cycle rather than to a calendar quarter
