New Unit: Filter Options

With a new heat pump inside and outside unit to be installedI have filter options. Since one family member has allergies, I wanted the best filter for that. What is recommended?

Unhappy filtering

The most thourough is most likely the electronic air cleaner (EAC),
It's expensive BUT it does the best job of removing things in the air stream.. The only draw back is that you must keep it clean, this is easy... you toss it in the dishwasher once a month and rinse off the pre-filter and dry it. The unit will come with the instructions on operator maintenance.
The cheaper, but less effective would be the Spaceguard 201 pleated air filter. You gotta change them out, but it's quicker than the electronic, and no moving parts, but less effective in removing contamination... If allergies are the main concern, get the EAC, Carrier makes a good one. A positive note is you have no filters to replace, they can break down though after years of use, but so does everything!

Electronic and pleated HEPA type filters are excellent for households with allergy problems. Pleated filtration, however, is not recommended for use in home central air filtration systems where heat pumps are involved due to airflow restrictions caused by the high probability of such filters clogging up much more quickly than electronic filters. Both types of filters require proper regular maintainence in order to be effective at controlling allergens.

The odd thing is you can ease the maintainence burden, keep up the airflow and actually get better air cleaning by using the two types in conjunction with one another. The EAC is installed with the indoor blower section and the HEPA type filtration units are put in individual room.
