Flow through humidifier concern

[sparkchaser61]

I have an aprilaire 401 filter...it is a "two year" filter composed of a paper/cloth material. My concern is ,if I install a flow through humidifier.... I will be pulling moist air through the filter and acrossed the fan and A coil. I think this will damage the filter and cause mold to form. Have any of you HVAC tec's had any experience with these problems.

2 years? Meaning filter changed every two years? I never heard of this. I even looked it up and says replace one or twice a year.

No need to worry. if this was an issue, they would done something else.

The humidity in the air is no higher than a hot muggy summer months.

Aprilaire / Space-Gard #401 High Efficiency Filtering Media (2-Pack)

These are the original, OEM expandable "accordian" style, factory recommended replacement filters for the Aprilaire/Space-Gard Model 2400 Air Cleaner. MERV 10 rated.

The filters ship like a collapsed accordian and are expanded into a plastic frame within the air cleaner cabinet. The filter is snapped into the plastic frame and held in place with existing pleat spacers. Assembly instructions are printed on the product carton.

The air cleaner media in the Model 2400 can last from 6 months up to 2 years. If installed on a 5-ton system, in the presence of high concentration of particulate, or if the furnace fan is on continuously, it may be necessary to change the media more frequently. In any application, the life of the media is dependant upon the total volume of air being moved through it as well as the amount of particulate it is filtering.

This is from the aprilaire web site.......but I change it every 6month to 1 year


Thanks for the information
