Conversion Kit to install 400-04A (6" Main Filter) in MA400 Mistaway Unit.

Using a conversion kit, you can convert your older model MA400 to use a 6" main filter.
The 6" main filter is used in the new MA400C 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.
