Question on filter size
On the infinity carrier system, the quote includes "installing a properly sized 1" filter slot." There is also the option to install the aprilaire 2210 media style air cleaner for $495. I don't know that we need the air cleaner. Should I inquire about price for a 4" media cabinet? Is the filtration better with the 4" or is the benefit just that you do not have to change the filter as frequently as the 1"? In the past we have used the highest rated filtrete filters and changed them monthly, just as a precaution for our daughter who has mild allergies (she has been fine in our house). Just trying to figure out if the cabinet/larger filter is more for convenience or if it is actually a better filter.
