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. It measures 8 x 11.75 x 1 inches, part number 5772. One machine, one panel, with nothing else named against it. The 11.75 in side is sometimes written as 11-3/4, the same measurement in fractions.
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. MERV 11 is rated at 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. Replace the filter every 12 weeks or at the end of a harvest.
Key Features
- Anden part 5772: The number to match, one panel per unit
- 8 x 11.75 x 1 in: Also written 11-3/4, 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: Rated at 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 part 5772 fits
- Every 12 weeks or every harvest: An interval tied to the grow cycle rather than to a calendar quarter
