Carrier Filter Housing- must I use a Carrier element?

[bm17601]

I haven an Infinity system with a 16"x25"5" media filter. I am wondering if a Honeywell Merv 13 element would have too much restriction compared to the Merv 8 Carrier element? I was considering the Infinity Air purifier but had decided to keep the media filter. Thanks in advance!

The short answer is that standard air conditioner blower motors will not deliver adequate, designed, airflow to achieve the SEER and capacity ratings because almost all of the installed duct systems are already too restrictive even with the standard throwaway filter. Low airflow is the number one major cause of compressor failures.

On a gas furnace, low airflow raises the temperature of the heat exchanger and the air output, This leads to heat exchanger stress and failure (major safety issue.)

Choosing equipment with a variable speed blower is the consumer's safest choice when considering better filtration.

See page 4 Fig. 3. Capacity, Pressure Drop and Area of F200 Filter media. http://www.giveme5.honeywell.com/Product/F200/F200%2068-0238ef.pdf#search=%22Honeywell%20Merv%2013%20%20fi lter%20pressure%20drop%20specifications%22

The final pressure drop of .5 inches static is equal to the available total pressure drop of a typical furnace.

The infinity system is a variable speed fan system and it does a static pressure test everyday at 1pm. Yes you can try different filters however you may have to tell the system you changed the filter or have your service guy reset your system for the new filter otherwise your system might think the filter is dirty.
