20030812 ordered two replacement filters ("media") direct from Aprilaire. Replacements are #201 High Efficiency Filtering Media. Also available are the brackets, edge pieces and electronic manuals. Re-ordered in 2005.
The HVAC coils also have a UV lamp over the coils, a UV-Aire with a 12-inch bulb. The bulb should be replaced every year or two for full efficacy.
