Conversion Kit to install 1200-04A (6" Main Filter) in MA1200 Mistaway Unit.
Using a conversion kit, you can update your older model MA1200 to use a 6" main filter.
The 6" main filter is used in the new MA1200C Mistaway Collector model.
The benefits of the 6" main filter are both lower cost and longer life than the 4" main filter used in the previous model.
Note: The carbon filter used in previous models is eliminated with the new 6" main filter setup.
If a carbon filter is needed, it is an option to the Hepa After Filter.
