Slightly OT, but, this seemed as good a place to ask as any:
Our water is from a shallow well & we have a small whole house water filter that takes the 10” x 2.5” round filter cartridge). The water tastes fine & tests fine, but sometimes does have a bit of sediment in it, therefor the filter.
I was looking at replacement filter cartridges online, and was rather surprised that most did not state flow ratings, and, others stated the same flow ratings for everything they carried, from variable density 5 and 10 micron spun polyester filters for medium sediment filtering to 1 micron spun polyester filters for fine sediment filtering to activated charcoal filters for drinking water filtering: The sources that say anything all state 1 gpm.
1 gpm is really slow! Possibly this is sloppy marketing? But sites like Home Depot don’t seem to provide this info., and going to major mfgr. sites like 3M and GE, this rating is not there either. The wrapper for the last 2-pack of string wound filters I bought is long gone (from Rural King, brand unknown, but some cheap string filters shed their own fibers - sheesh! while back I found a very old pleated filter @ my Dad’s with a rating of 10 gpm, but, the material is so old it’s brittle. No help there...
Generally, asking the bigger companies is a roll of the dice as to whether one will get a reply, or, anytime soon. And Filtrete (3M), for example, doesn’t have a chat option for questions...
I’m thinking my best bet is to go on Amazon (yeah, I know...) and query sellers, looking for a rating of 5-10 gpm. But, I’m open to other ideas and input.
I’d also certainly be interested in other’s experience with the variable density spun polyester filters, as I’ve not tried those.
Thanks!
Paul, I would be happy to assist but unfortunately I use a gravity type Berkley type filter with municipal water. Maybe someone else with a well might know. Another place to ask would be the Prepper thread.
