Air conditioner cleaning and adding WEB filters--questions

July 14, 2008

Jeff, I just bought a small, portable AC unit, 12,000 BTUs, and I want to

add a WEB or similar filter to it. My house may have hidden mold, as I have

biotoxin symptoms, and occasionally smell a faint musty odor. I will probably

have to tape the filter on the outside of the AC unit.

I looked at the WEB Products website, and called them for recommendations.

I was told that their filters might restrict air flow and burn out the motor.

I don't know how this AC motor compares to a more standard window unit.

What do you think--is this likely? Would a higher MERV number restrict air

flow more? What MERV rating is best for filtering out mold spores?

I plan to use the AC as a dehumidifier as well as for cooling. This latest

batch of rainstorms has made the house much more humid. Not good. So I need

to figure this out right away.

Thank you.

Judith

Surella,

The mold is inevitable if you use the filter that came with the A/C as

these filters are all completely inadequate. After thorough

cleaning/disinfecticleaning/disinfecti<WBR>ng you must purchase WEB p

and cut it to fit. This is a MERV-7 filter (MERV 8 is preferable but

not available). The filter probably does not fit inside the A/C filter

holder so it will probably have to be placed over the front intake,

taped in place so that there is no air bypass.
