Customer Questions & Answers

Does this filter have a charcoal base?

Asked by: Babs
No, it does not have a charcoal base. It is made from with a sturdy plastic frame covering a green filament material. Per instructions the filter is washable. Therefore, no charcoal to ruin or charcoal dust to clean up after.

Can these filters be used in mobile home units also?

Asked by: Sible77
Yes it can be used in a mobile home HVAC system. I live in a mobile that had the old fashioned cardboard and charcoal base filter. The prior owners had only one filter installed when they really needed two..

Does it block too much air flow?

A filter this "good", must be dense to get such small matter filtered. It worries me that the air flow through it would be too slow, and maybe hurt the furnace, and/or decrease it efficiency. Any one know anything about this? Any Pros use this type of "dense" filter? What do the pros think about the air flow?? Thanks, Karl K
Asked by: KarlK
It's probably not as dense as you are thinking. An FPR 5 (Home Depot rating system) filter is about equivalent to a MERV 8 filter, which for many residential systems is a good trade-off between good air quality and stress on the forced air system. This filter is FPR 4, which has no directly equivalent MERV, but would be lower than MERV 8 and therefore allow for increased air flow.

Rated 1 out of 5 by from Not for tight spaces No problems cutting this down to size. It only took a few minutes with diagonal cutters and a box cutter. However, the plastic tabs that hold the frame in place stick up so that the frame is actually a little thicker than a regular disposable filter. My filter had to slide into a slot that did not provide much leeway, so it would not fit. Since I had already cut it to fit, I could not return it. I wound up gluing it with my hot glue gun and cutting off the tops of the connectors with a box cutter.

Rated 5 out of 5 by from Very "green" as it is washable, not going into the trash! I change filters in my furnace every month, this will save me money and not end up in the trash. I just keep one of the disposables and use it for one day while this one dries completely. It fit perfectly and is very sturdy. Just wish they would carry more sizes in the store so more people could buy them without shipping costs.
